We are always eager to upgrade our phone to the latest version so that we might enjoy the new features and apps that come with a new update. Ask a Galaxy S2 user how keen he is get the Jelly Bean firmware update. While most of times we are happy with the new things introduced in an update, it also happens sometimes all our hopes are undone when we have to face a bug or lack of a favorite  feature that we used to enjoy on an older firmware.

It happened to me a couple of weeks ago when I updated my Galaxy Note 2 to the Android 4.1.2 Jelly Bean firmware. For some days I remained busy with exploring the new features and enjoying them. It was later that realized that there was something wrong with the WiFi connectivity. Everything else was just fine but this issue was great enough to make me think again. “What should I do now?”- I kept thinking. Then I decided to try another firmware in a hope that it might solve the problem. But again the same WiFi bug! With Android 4.1.1 on my Note 2, I was happier, so I downloaded the Android 4.1.1 firmware and flashed it.

How many of you ever wished to downgrade the firmware of your Android phone? Only a few. The present article is for those people who are looking a way to go back to Gingerbread from Ice Cream Sandwich to Ice Cream Sandwich from Jelly Bean, or from Android 4.1.2 to Android 4.1.1. The tips described below will also be helpful to even those who want to downgrade their Samsung Galaxy device to Gingerbread from Ice Cream Sandwich.

Before you Actually Downgrade, Try a Few Workarounds

In most cases, the wish to downgrade the firmware of one’s Android device’s firmware is a rash judgment. I say this because I have heard a lot of people saying, “I upgraded my phone’s software yesterday…Now it is very slow and battery is draining fast…I want to downgrade.”  Is it really worthwhile to think of downgrading just a few hours/days  after installing a new update you waited for long to get? Think again!

Our OEMs release an update after testing it and when its performance is found satisfactory. I wonder why new updates aggravate to our worry rather than pleasing us. The most common issues why we consider downgrading are:

  • Slow and laggy performance
  • Battery drain
  • Connectivity issues: WiFi or data connection
  • The absence of an important feature found in the previous firmware.

Here are a few workarounds that you can try to fix the above-mentioned issues.

  • Try data factory reset a couple of times after upgrading your phone’s software. Follow the Step# 10-14 from below.
  • The Lithium-ion battery used on your device requires a proper synchronization with the new software, it ‘s normal that you face issues like fast battery drain and battery heat up after upgrading. You must have seen the same battery problems for a week when you bought the new device. Usually, the sync requires 3-4 charge and discharge cycles to complete. I would recommend you to avoid plugging the charger into your device frequently. Charge the device after turning it off, let it charge fully. Then use the device until the battery discharges completely out of use and then turn off the phone and charge it. Repeating this for a week will certainly improve the battery performance.
  • As for WiFi or internet connectivity issues trying a data/factory reset might help fix this. You can also try rebooting your device a couple of times.
  • As for the absence of a feature you liked in the previous firmware, you can find an alternative among the more than 7 million apps found at the Google Play Store

In case, the above troubleshooting measures do not yield any positive results, your decision to downgrade was right.

Disclaimer & Warning

Please note that the method described here has been tested (by me, more than once) on Galaxy S4 (Android 4.2.2), Galaxy S3 (Android 4.1.2 to ICS), Note 2 (Android 4.1.2 to 4.1.1) and Galaxy S2 (ICS to GB). I have not been able to test for downgrading to GB from JB. All the same, I would like to warn you that the procedure is considered risky. Proceed only if you understand the gravity of such things and make sure you are not drunk while following up the steps. We’ll not be responsible for any data loss or damage done to your device.

Downgrade to Gingerbread from ICS or JB

Those willing to downgrade their Galaxy device to Gingerbread from Ice Cream Sandwich or Jelly Bean should not follow the method given here unless you have the firmware files with Bootloader or PIT. In case you have a PIT file for your device model, select it while installing the firmware and do not forget to check “Re-Partition” on Odin.  We warn you against proceeding with the single file installation method as described below.

However, if you are to downgrade to a lower version of Gingerbread from a higher version of GB ( from Android 2.3.7  to 2.3.3, for example), you can follow this tutorial.

Getting Prepared:

The firmware downgrade drill for the Samsung Galaxy devices is not much complicated as compared to the phones manufactured by other brands. It requires you to boot the device first into Download/Odin Mode, and then into Android Recovery Mode. I hope many of you would be acquainted with both the methods. Even if you are not, it doesn’t matter.

  • Download the downgrade firmware for your Samsung Galaxy device and extract it on your computer. A good source to download Samsung firmwares is Samsung-Updates. Type your device name in the search box at the sidebar, you would find it hopefully. If you do not get it, let me know (your device and country). To find out the correct firmware you can use CSC codes.
  • Download and install Samsung USB Drivers on your computer. Skip this step if you already have it.
  • Download Odin Firmware flasher and unzip it (if you get any error with Odin3 1.85, try the greater version): Odin3_All Versions   [Mirror Link]
  • Since the downgrading procedure will delete all data stored on the internal SD Card of your Galaxy device it will be better to backup your messages, contacts and installed apps. These nice free apps will help you backup your data easily.
  • Charge your device’s battery to the full
  • Make sure that you have turned on USB Debugging from Settings> Developer Options>.

Before You Downgrade Firmware:

Please note that in some cases, downgrading firmware might lead to IMEI loss. This occurs due to the difference in EFS location in newer and older Samsung firmwares. Several people who tried downgrading to Android 4.1 or 4.2 from Android 4.3 have reported this issue. We, therefore, strongly recommend you to be prepared for good. To backup your EFS partition/IMEI, please refer to the following tutorial:

How to Backup and Restore IMEI on Samsung Galaxy Devices

Installing the Downgrade Firmware:

Installing a firmware version that is lower than the current one is just the same as installing a higher one, but you have to do one more thing that you do not usually do. Finally, here are the steps on how to downgrade firmware on Samsung Galaxy devices. I assume that you have already done as described above, so let’s go ahead.

  1. Turn off your Samsung Galaxy device whether it a phone or tablet and boot into Download/Odin Mode. If it is a phone, you can enter the Download Mode doing this: Press and hold the Volume Down+Home buttons together and then long press the Power Button till the screen turns up. Now press the Volume Up key to enter the Download Mode. In case you have a Galaxy Tab device, do this: Press and hold the Volume Up+Power buttons together, and then press the Volume Up key when prompted.
  2. Now go to the Odin folder and run the .exe file there.
  3. This is the time, you have to connect your device to the computer using a compatible USB cable.
  4. When the connection between the device and computer is established, the ID:COM port at Odin will turn to Yellow or light Blue (depending on the Odin version you are using) and you’ll see “Added!! text in the message box below.
  5. Make sure that only “F. Reset Time” option is checked on Odin. The “Auto Reboot” option is checked by default, so please uncheck it.
  6. Okay, now click on the PDA button on Odin and select the firmware file in tar.md5 format.
  7. Now click the “Start” button on Odin. This will initiate the firmware installation. Wait till it finishes. odin-flashing-firmware
  8. Finally, when you get a “PASS!” message on Odin, remove the USB Cable from your device.
  9. Now open the back panel of your device and pull out the battery. Wait for about 60 seconds and reinsert the battery back to its place.
  10. Now reboot your phone into Android Recovery mode. If you have a smartphone, you can do it this way: press and hold the Volume Up+Home buttons together and then hold the Power button till the screen turns up and the Samsung logo blinks for two times. Release the Power button but keep the other two keys pressed till you see a black screen with green Android bot and Blue text. In case you got  a  Galaxy Tab or Note 10.1, press and hold the Volume Down+Power keys together for a few seconds till you see the yellow triangle with Android bot followed by a black screen with blue text. android-recovery-on-galaxy-s3
  11. In the Recovery mode, you will have to use the Volume Up/Down keys to scroll up or down, and the Power button to select an option.
  12. So, scroll down to “wipe data/factory reset” option and select “yes” to confirm your choice.
  13. Now go to “wipe cache partition” and confirm the choice.
  14. Finally, go to the “reboot system now” option and select it.

Your device will boot now and it might take a longer time than it does usually. When it completely boots up, it should be on the downgraded firmware you installed. Cheers!

  20. I have galaxy note 2 GT N8000, I want to downgrade from 4.4.2 to 4.1.2 because all the software are not compatible. i made the upgrade using Odin and could not go back

  21. Hi,
    i have recently try to downgrade my Samsung S3 Neo (GT-I9300I) to JellyBean…I have done all the process thru odin it shows me Pass also….But now my phone cdnt get in to normal boot means ….it only restarts everytime on the boot logo of samsung…it repeatedly restarting only…so please give me a nice sollution to sort out or even just make my phone work…even any version if it work jelly bean i will b more thankful…..and also i cant gert into recovery menu means even if we need format manually by pressing Vol UP-Home-Power Key….its also only restarting….but its shows in the corner recovery booting but cdnt get in to the menu….

  22. Hey Rakesh, I have Kitkat 4.4.2 on my Note 2 which i updated using Odin, but the battery drain is really fast. I have tried to factory reset, but the problem is still there. I would like to downgrade back to 4.3 using the odin. Can you please tell me how to do it?

  23. Well, the Sprint S5 sport model does not have a locked bootloader but I can’t say anything about downgrading unless I see what Odin says when you try to install the firmware.

  24. There’s a ton of articles on downgrading to KitKat 4.4.2 from Lollipop. You are saying it wont work for me or anyone?

  25. It’s because the Android Lollipop firmware has an undowngradable bootloader. You ca install a greater version of firmware though.

  26. I am trying to move from Lollipop 5.0 back to Kitkat 4.4.2 on my S5 sport (sprint G860). We keep getting a “FAIL!” error in odin. Any suggestions? I did a factory reset of the device yesterday however did restore it from a backup since I needed to use my phone…

  37. You can go back to ICS instead( given the fact ICS is available for the phone which is not there, I suppose).

    If you are having any issues with 4.1.2, you can try a data factory reset.

  38. Hey can i downgrade my samsung galaxy grand 2 from 4.4.2 to 4.3 i am facing lots of issues plz help

  39. Hi Rakesh,

    Yeah. A long time ago. 🙂 Thanks.

    But that flash you helped me with in this article, was my first :D. Can’t forget your first :))


  40. Hi Rakesh,
    I just found this site. I have a Samsung galaxy s3 (sgh-t999) for T-Mobile. Trying to downgrade from android 4.3 to 4.1.1 and so far you are the only person that offers some hope of that happening with this phone.

  41. hi i have galaxy s2 i757m its a unlocked mobile used in india but tried to update jb through odin it got suck and then a tried to restore stock firmware but i couldn’t help me to resolve this issue

  42. pls help

    i have samsung s4 gt 19606, when i upgraded it by mistakenly i clicked boot loader using odin. now i got an firmware issue. how should i recover my mobile ?

  43. Please help me I have GT-P3100 and I tried all ways on internet but still can’t fix! >:(
    I have the Firmware Upgrade encountered an issue problem pls helpppppp.

  44. Well, rooting will void the warranty but you might find an exploit that roots the device without doing that. As long as you use a tested method carefully, there should be no risk in rooting. I half half a dozen devices, all rooted on the day they’re bought, but I have not face any problem on any of them.

  45. Will THAT void the warranty? Because that phone’s gotta last and if something happens to it and I can’t replace it, I’m screwed.

  46. Downgrading the KNOX bootloader might prove risky. It’ll be good if you root you phone and remove the bloats and use 3rd party apps to get better performance.

  47. If you own the Snapdragon model of the S4, you should have used Saferoot to skip flash counter tripping. If you have already tripped it, Triangle Away is the only solution for you currently.

  48. Thanks for help..i try those step but still can’t..

    so i just install new firmware stock..done.it back to normal.


  49. Try to re-flash. IF success, go into recover and wipe data/cache partition/dalvik cache.

  50. Hello Rakesh, I am soon to have an SGH-T989 (T-Mobile Samsung Galaxy S2) and it will come with Jelly Bean. I’ve heard people both say the update is good or bad, but I can’t exactly trust it. I want to downgrade but I’m afraid I might void the warranty. Is there any way to get GB on my S2 without tripping KNOX/voiding warranty? Thanks.

  51. Hi Rakesh, need help on this..how i can get my offcial kernel? any link for the official kernel? how to use the ( .tar) file? mostly kernel i think..thanks

  52. There is a problem with connecting to Sprint LTE on my L900. I’m still with Carbon ROM nightly 4.3.1. But only have 3G. I’ve switched t Sprint Internet in the options but the selection bubble disappears after a while. On top of that, it often disconnects from the network and reconnect. So for now I chose to stick to CDMA/EVDO.
    Anyone knows what’s going on here?

  53. So if I leave out the bootloader what bootloader will it flash. The at&t Samsung note 3 has a special burned in boot loader. I thought the leaked MLG 4.4.2 had the same bootloader as the NC2 4.4.2 OTA update was the same but it’s not. But what I was thinking since NC2 and MLG was the same firmware that would be ok then I could revert back to MJ5 4.3 then but its just getting away form the Samsung kitkat bootloader. I’ve search but can’t comfirm this being done yet using odin. unless there is a way to format the system to get this bootloader of the phone then burn MLG 4.4.2 on the system without tripping knox or going into a software soft brick. Thanks for the reply and let me know something. Samsung and At&t has gave us a boot on this.

  54. Is there a way to install the leaked version of MLG 4.4.2 over the OTA update of NC2 4.4.2 on At&t Samsung note 3. Trying to get back to MJ5 4.3. I don’t think that I can downgrade the new OTA NC2 4.4.2 to MJ5 4.3 because of the bootloader. that’s why I was thinking if this can be done with the leaked Kitkat then I can go back to MJ5 that way with odin 3.

  55. If you want to go back to 4.1.2 from 4.3 all you have to do is use Odin. Flash stock 4.1.2 onto 4.3 you get an error “unsupported firmware” then put your phone back into download mode (volume down+home button+power) next flash CF-auto root. After that you can boot into recovery (volume up+home+power) in recovery format everything factory reset, format cache. Last reboot your phone it should reboot into 4.1.2

  56. Hello Rakesh, I been looking around trying to find the right guide to downgrade my Note 2 T889 from 4.3 to 4.1.2. Is there a link you might be able to help me that can guide me the right direction in doing this please? Thanks in advance!

  57. Downgrading will go fine or not, depends on whether your device has secure bootloader or not. As for EFS thing, it’s a system partition and you need to have root access to access and backup it.

  58. Hi Rakesh, what about downgrading the latest firmware to the one right before it, both bearing the same Android version (4.1.2), shouldn’t it be as simple as your tutorial, and lessen the risk of losing EFS like when downgrading from 4.3 to 4.2 / 4.2 to 4.1?
    And what about backing up EFS from device that is NOT rooted? the reason i want to downgrade is that so i can root my device using Tegrak’s kernel, as he doesn’t support the latest firmware.

    thanks for this awesome tuts, cheers

  59. Hi Rakesh,
    I’ve been following these posts after rooting my Note 3 (N9005) and I’m now trying to restore it to original condition.
    I’m new to all this and not confident about what I’m doing. I’ve downloaded stock ROMS for Australia and Hong Kong (the phone came through Kogan and they assemble under licence in HK).
    In all my attempts, after waiting the 10 minutes or so for Odin to transfer, it comes up with fail, ext4 error.
    This happens with all images. I’m not sure what section in Odin (3.07) to use so I tried them all.
    I used the CF-Auto-Root-hlte-hltexx-smn90054.tar.md5 to root the phone, then put in Philz files to access the advanced options, but as I said, I’m not sure what is going on.
    Can you see where I’m going wrong. I’ve tried changing the CSC but that didn’t work, Kies won’t look at my phone at all so I’m left with Odin.
    Any help will be appreciated….
    Thanks, Peter

  60. Do you have any recommendations as to where to get a multi filefirmware so that I dont touch the bootloader? Please dont forget about me 🙂

  61. Hi, I downgrade is just a downgrade. I doesn’t matter why you are going to do that. If you want to try downgrade, the best way will be to find a multi file firmware and then you will be able to downgrade the firmware without touching the boot loader.

    A more riskier way will be to downgrade by flashing 4.2.2 firmware. In case you encounter any issues, I you will have to install the same version of firmware as you currently have.

    When I get home, I will try to find some workaround for you. 🙂

  62. Rakesh, I tried to unlock my phone via the network codes I received. The company that supplied to me sent me to your thread to downgrade my os from 4.3 to a lower version. Bell Canada Model SGH-i747m. I have backed up my imei etc and have the phone rooted. I will attempt to downgrade the version following your post here. But what is this i read about canadian phones having secure bootchain and not being allowed to be downgraded? I just need to downgrade to be able to unlock the network.

  63. i have read all the blogs yesterday i tried with 8gb pit csc it was working fine but today i tried with only pda downloaded from samsung update site. is service center people make it to work again

  64. I updated my S4 GT-I9500 via OTA. Then I rooted my device and flashed cyanogenmod 11 (official). I want to get back to stock 4.3. I tried flashing 4.3 firmware via Odin but it shows failed…fused 3 binary 2. Can you please guide me to revert back to stock 4.3?

  65. i tried using pit csc and other it was successful yesterday but today i tried by downloading official 2.3.6 software from the site. i got pass but my s advance is not working it stopped working. is there any way to make my mobile to turn it on

  66. Just kidding, I was installing the wrong firmware! I downgraded to 4.0.4, then upgraded to 4.1.1 using this method and it worked great 🙂
    Galaxy S3 I747, AT&T

  67. If it helps, in my “downloading… Do not turn off target!!” screen it says “Unsupport dev_type”.

  68. I cannot get the “pass” message no matter what I do.. I used both ODIN’s and everything. I’m really trying to unlock my S3 so I can activate it.. this is really irritating. How can I fix this? I followed the instructions perfectly.

  75. i have tried the tutorial several times already everything works as it should, but when i check the firmware on settings>about> it displays 4.1.2 🙁

  76. You can downgrade the firmware using the tutorial above. As for the SIM unlocking, you will have to google for that. You can also try the Galaxim app from the market.

  77. hi Rakesh i have a galaxy s3 i8190l(latin version) 4.1.2 im trying to downgrade it to 4.1.1 to see if i can unlock it, but no luck! any ideas on how to do it or unlock it?

  78. Hi Jacinda, downgrading to 4.1.1 from Android 4.3 will damage the bootloader, resulting in a hard brick. As far as I know the SIM unlock still works on the Canadian S3. Try this:

    Dail *#197328640#
    Main Menu
    [1] UMTS
    [1] Debug Screen
    [8] Phone Control
    [6] Network Lock
    [3]Perso SHA256 OFF

    Wait a few seconds then press menu and go all the way back to the main menu.

    [5] run EFS Sync()

    Reboot and done.

  79. hay thx for reply how do i find out if it has or doesnt have a secure boatloader im sooo computer illiterate its not funny lol

  80. i just got samsung galaxy s3 1747m 4.3 and im in canada but want to be able to unlock it for wind because its w kodoo is there a way to do so and do i have to downgrade to 4.1.1 to b able to unlock pls help???

  81. What do you mean when you say the phone is not booting? Is it bootloop, or is it not booting in download mode, or if the screen does not light up at all?

  82. @RakeshHello, I have same problem, did downgrade from 4.1.2 to 4.1.1 and phone do not boot. I have Samsung S3 T999V. Is there any solution for this ?

  84. Hi again, I need help finding my firmware I tried going to the websites you gave links to but it did not work, my device I am trying to downgrade is the Samsung Galaxy Tab 2 10.1 Model GT-P5113. I am trying to downgrade it as 4.2.2 to 4.1.1

  85. Could I downgrade from 4.3 to 4.2.2 using the 4.2.2 for SCH-I545 firmware you provided in the “How to Install Latest Official/Stock Firmware on Samsung Galaxy S4 (All Models)” tutorial?

  86. Thanks for the response. It wasn’t showing anything. Turns out somehow
    It was removed so I flashed a stock MA5 Kernel and Modem. All is well.

    Thanks again, Rakesh.

  91. It is a CDMA phone and do not have an Access Point option. Wifi is working fine. Even I talked to Reliance about the settings and they said the CDMA sim cards do not require any APN settings for running mobile data.

  92. I think it’s a modem related issue. By the way, did you check your APN settings under Settings> More network settings> mobile data> Access Points

  93. yes I can see my imei no. in about phone>status> Imei. I have a doubt If the “Kernel version” has anything to do with this? Please Help

  94. I tried another sim as well. but the mobile data is not working. one more thing, from the shortcut key menu (which comes when we pull screen down) whenever I try to click on mobile data button, It say “insert sim card to access the network services”. Does anybody has any Idea about it? Is there any software required for this and I might have lost it while upgrading or factory reset?

  95. I have samsung galaxy s3 sch r530u.I wanted to downgrade my 4.1.2 to 4.1.1. followed the instructions and I am happy to say that It worked. but I did not succeed in what I intent to do. Actually I have a reliance CDMA connection and I was using mobile data. but after I upgraded the software( which came with automatic notification) I was unable to connect to mobile data. and even after this downgrade I am not able to connect to mobile data. Can anyone tell me what should I do?

  96. How Long does it. take to install firmeware? Possible few hours samsung logo blinks on screen and i Walt Now two hours is is possib that i may have another Recovery Modus?

  97. Hello ! I’ve been trying to unlock my T699 ( galaxy s relay 4g) from T mobile. Ive tried the secret menu method which didnt work and then bought an unlock code which didnt work. I’ve just tried the downgrade from 4.1.2 to 4.0.4 hoping that would fix it. After reboot the phone just shows a black screen. Any ideas? Really appreciate your help!
    many thanks, Declan

  98. and one another thing i downloaded firmware from samsung updates, but it is boot.img file and not “tar.md5” is it ok?

  99. hello!!! i m using SHG-t989 samsung galaxy s2, it came up with 4.0.4 and i upgraded to 4.1.2 after that , i feel battery heating up very much and sudden battery drain, many a times, should i downgrade to 4.0.4???? with your tutorial ?

  100. Thank you Rakesh, now I have downgrade to android 4.0.4 and my touch screen seems better then Jelly Bean. You are amazing

  101. I have Galaxy Note Korean (SHV-E160S) run on Jelly Bean 4.1.2 and got the problem with touch screen sensitivity. I want to downgrade to ICS 4.0.4. Do you have any idea will this will fix this problem? Please let me know …

  102. Sorry I failed to mention a key detail. Right under NETWORK LOCK is a NETWORK CONTROL You MUST change that setting to AUTOMATIC. I was very tired while working with this booger of a tablet. What it boils down to… it is set strictly for LTE.. on AT&T. You’ll acheive unlock but then it’ll never ask for the network pin on boot. It’s unlocked but T Mobile uses a frequency than AT&T and unfortunately the SGH-I497 version of the tab 2 10.1 does not operate on that 4G bnd for HSPA or LTE. Unless something changes you’re stuck on 2G/EDGE:2. You have to change all the band selections to AUTOMATIC to make this tablet work even after it’s unlocked. That includes CDMA also. Don’t get selecting specific frequencies. The options you need all say AUTOMATIC as option 1. If you don’t know what I’m talking about just go in and look around. You’ll find what I’m talking about 🙂 There is an area where you can do a restore of default settings if need be but I believe you’ll have to do the actual unlock proceedure after that. I’ve never done the restore but unless you make a backup after you’ve unlocked the tab it’ll restore the NV data I’d imagine. If you’re truly interested and totally lost leave a reply and I’ll go back in and find all the settings that need changed to use the tablet on other carriers. Good luck! I’m sorry I was incomplete with the aforementioned post.

  103. Lag and TouchWiz UI from Samsung are deeply interwoven and so you cannot get rid of lags altogether on a Samsung ROM. Root your device and try a custom Rom for bett experience.

  104. Do you know if 4.3 will fix the lag issue, I have tried everything else removing animation, unlock effects, disabling all Samsung apps and the phone still shows lag I think I will return the phone instead if there is no solution

  105. Hi, I have a Samsung Galaxy S2 Epic 4g Touch from Virgin Mobile and a couple of months ago, I updated the phone from ICS to JB and now I would like to change it back to how I bought it, would your tutorial work on my phone too? Because most of the tutorials I have read are for the new version of the S2.

  106. Wow I have figured out something… new???… I have been playing with my SGH-I497 Galaxy Tab 2 10.1 These are a total pain to unlock from network without a code… I downgraded to 4.0.4… now back up to 4.1.1 searching for “ServiceMode” & I just found it!!!!! Wanna unlock your tab for FREE? This probably wont wotk if you’re on 4.1.2 JB as it wont on the S3… so downgrade to 4.1.1. Here is how to unlock… step by step… never read this anywhere before. 1) Enable USB bebugging in Developer Options in the settings menu. 2) Go to th calculator and enter the following. (+30012012732+ this will give you a phone dialer 3) On the phone keypad enter the following *#197328640# Welcome to ServiceMode and the key to your free unlock. Now… select the following options… [1] UTMS, [1] DEBUG SCREEN, [8] PHONE CONTROL, [6] NETWORK LOCK, [3] PERSO SHA256 OFF…. now we wait 30 seconds… tick tock… on the button in the top right of the screen select “back” from the drop down menu. Now… select the NEW option [4] Its long but has “NV” in it… push it and wait a few seconds. Now…. Push the power button and shut the tablet down. On a phone you would remove the battery for about a minute… cant do that with the tablet easily but it works anyway. Some may say to put in a foreign sim card, but I did this with no sim in at all… my AT&T tablet it now running on T-Mobile… and I’m posting this with it! Hope this helps someone and post this everywhere after you’ve done it. Hiw to downgrade to 4.1.1 is laid out in the article above. I chose to go up to 4.1.2 to see if I remained unlocked… I did 🙂 So we’re even safe to upgrade if that’s your thing. I’m going back to ICS though lol.

  107. Keep only one things on PC, either Kies or the drives (preferably).

    Reboot PC and device.

    Try reinserting the USB cable.

    Make sure that your download mode shows “downloading…do not turn off the target” message.

  108. Hi, i am trying to downgrade my samsung galaxy tab 10.1 from android version 4.2.2 to 4.1.1, i have downloaded everything including samsung kies and drivers but Odin is not recognising my device in download mode, i saw below that someone else commented saying the same thing and i followed the steps you suggested to them but still got nothing, can you provide me with any help?

  109. The downgrade went perfect! I was able to unlock using the calculator like I had hoped & added a few little things that I can’t get to work quite right with JB. Thanks a million!

  110. Wow you’re fast! Thank you kindly Sir 🙂 found a better place for stock firmware to boot even!

  111. Hi… wanting to downgrade sgh-i497 from 4.1.2 to 4.0.4. I located 3 versions and all have 4 tar files… also a pit file. Never used 4 files before to downgrade… I know one is the OS and another the modem, not clear on the other 2 though. I usually use odin 3.04 so 1) Do I need all 4 files plus the pit file or just the big one for the OS? 2) If I need more than one file, can I add more than one to odin? And how to do that would also be helpful 🙂 Thanks!

  112. You made a mistake. Downgrading directly to GB from JB will corrupt the bootloader and that’s why you are not able to get into recovery mode.

    Here is the solution:

    Download Odin 1.85 from above

    Download this firmware file: http://hotfile.com/dl/160905578/f4ed0fd/I8530ZSLE5_ZSLE5_OZS_Taiwan_Android_2.3.6.rar.html

    Extract the .rar file. You will find 2 files inside.

    Put your phone download mode.

    Launch odin

    Connect device to PC

    Click on PDA and select the file with CODE in its name

    Then click CSC and select the CSC file.

    Check Auto reboot and F Reset Time on Odin

    Hit the start button.

    Let me know what happens.

  113. After downgrade its not going to recovery mode.plz give link for samsung galaxy beam 2.3.6firmware

  114. sir can i update s3 19300 4.2 or how to use and install s4 features like smart pause , eye scroll

  115. Check if the firmware file is correct and USB debugging is enabled. If these things are fine, try using a different version of Odin (1.85 or 3.07).

  116. help me T_T I’ve did everything right but at Odin i got a problem it’s said

    “All threads completed. (succeed 0 / failed 1)”

    I did it more then once but it’s still giving me the same thing *_*

  117. Hi Sir, will this work with the 4.3 update for S4? I upgraded to 4.3 and would like to downgrade to 4.2.

  118. sir i have samsung galaxy beam.i upgraded from 2.3.6 to 4.1.2 .but when i restarted my cell now its have charge problem.when i connect the charger the charging icon appears at battery but not storing charge.i tried to downgrade bt when download complet and get restart its get stuck.plz tell me how i should downgrade it to 2.3.6

  119. Downgraded Samsung Galaxy Note 2 SGH-T899V (Mobilicity, Canada) from 4.1.2 to 4.1.1 and then Unlocked successfully. Worked like a charm! Rakesh Shuklajee ko humaari taraf se dhero pranaam!

  120. Is the CSC the code you get from the baseband version code? If it is, here is my baseband version: I8190LUBALJ7

  121. Hello! I have a S3 mini GT-l8190L on telcel. It is at 4.1.2 and I would appreciate having it downgraded to 4.1.1

  122. Hi. I have a SIII SGH-1747M on SaskTel (Canada). It was upgraded to 4.1.2 and I want to downgrade it to 4.1.1 Which firmware should I be using to do that? Thank you.

  123. Uninstall Kies temporarily, install the drivers again, reboot computer and device and try again.

    Make sure to install either Kies or the drivers.

  124. The connection between the device and computer isn’t established (the ID:COM port at Odin not changed at all). I have installed Sumsong USB driver_1.5.27.0_2 and Odin 3_V3.04. Kies Firmware recognize my phone (in normal mode) but the Odin doesn’t in Download/Odin Mode. I tried this with two different computers. what should i do with Odin? I can’t go to the next step. thanks.

  125. Hi. I tried this. On note 2 with 4.1.1 flashing and downgrading from 4.1.2. After doing the whole thing in a way it is described, I could not get onto network, had access to emergency calls only. IMEI was numerical starting with 0049, so flashed recent modem. But then, you simply do not get any benefit of 4.1.1. Why I am back to 4.1.1 is a great battery backup which is a huge problem with 4.1.2.
    If you have any solutions to this, it would be highly appreciated, rather modem for 4.1.1 which will work in this case? or downgrade bootloader, a risky task though!!

  126. Another quick question, I have a MAC and Odin doesn’t work. Can Heimdall do the job?

  127. Hello! I have a quick question, I have a Samsung Galaxy Note 2 locked to Telus and the version of the model is SGH-I317M, android version 4.1.2. I want to downgrade to 4.1.1 so I can unlock it, but looking at the firmware on Samsung updates, I’m unsure of what firmware I should download. Am I suppose to download 4.1.2 because my phone is currently that version or download 4.1.1 because that’s the version I need to downgrade to ? Thank you !

  128. i actually ended up getting it a minute later after i posted haha. downloaded the wrong file, i was wondering why the file was so small.. I was like this can’t be the firmware file and then i found the right one. But thanks for the steps on downgrading! 4.2.2 was horrible compared to 4.1.1. x-x

  129. File extension should not be a problem, but you can try by adding .md5 at the end. Give a try with both versions of Odin.

    What your carrier’s name?

  130. i am install this soft ….i dont like this ….i want back my old phone…i have Galaxy Grand Duos GT-I9082….. Android 4.1.2 jelly Bean…..

    please help me …email me

  131. i am install this soft ….i dont like this ….i want back my old
    phone…i have Galaxy Grand Duos GT-I9082….. Android 4.1.2 jelly
    please help me …email me

  132. Thanks for your help. I am back up and running with version 4.0.1 No more random rebooting.

  133. Help please! I downloaded odin, along with the the firmware that I’m trying to downgrade to (4.1.1 since im using a P5113) and i just keep getting stuck on the samsung logo no matter what I do. Any ideas?!

  134. Android TAB 2 10.1 Downgraded from 4.2.2 to 4.1.1 (Flash games for my 3 year old son – what a pity that Adobe and Google only think of themselves!)

  135. You’ll lose root as soon as you change firmware, anyway. Nevertheless, for us, we rooted on 4.2.2, then downgraded to 4.1.1 with the wipe partition and factory reset options. We initially tried the downgrade without wiping and resetting and were stuck in a boot loop at the Samsung logo. Our units were GT-P5113, so perhaps the “ts” on the end of your model number is the issue and your firmware isn’t available. Just a guess.

  136. im on a gt-p5133ts Ive gone as far as to try to root it with no luck, it wont take the root file from xda nor their 700+ meg file of the original firmware of 4.1.1 honestly at a loss as to what to do? was thinking if I rooted id be good but it fails everytime

  137. Not sure what would be causing that. First, make sure you’re using the exact firmware for your device (as referenced above, I wasted nearly three hours trying to install firmware for a 7.1 rather than 10.1). Personally, I’ve never had the cache wipe fail, so I can’t provide much guidance. But a quick web search yielded many pages of people with this complaint about various, mostly Verizon devices, an issue which A.) Verizon deals with by swapping out the device and B.) doesn’t seem to have a solution (at least not one which I found). Otherwise, not much more I can suggest, sorry.

  138. That would have been ideal. Unfortunately, Samsung doesn’t provide 4.1.2 on their site for my device, and I don’t trust firmware I find in the wild.

  139. Im trying to do this on my tab now I hate 4.2.2 trying to go back to 4.1.1. I keep getting stuck at the Samsung logo, I did a factory reset but when I go to wipe cache I get a error and a reboot and back to logo. Oddly reinstalling 4.2.2 goes just fine. Any Ideas?

  140. Help! I have a Galaxy S2 i727R after upgrading to OS 4.1.2 it was randomly rebooting I tried reverting back to OS 4.0.4 vers I727RUXLF3. Following directions all went well and as described above until the reboot. The phone is saying the firmware upgrade encountered an issue select recovery mode in Kies. Kies tries to connect to my phone but does not recognize my device now (it did before). I have reinstalled the drivers and even uninstalled and reinstalled Kies, rebooted the computer several times. The error Kies gives me is “device not responding to resolve the issue reboot the device”. I have tried this several times with no results. Any help would be appreciated. Thank you.

  141. Yup, easy as the proverbial pie on my Galaxy Tab 2 10.1″. (Well, once I
    realized I was stupidly trying to install the 7.1″ firmware that is!!)
    And yes, no need (or even feasible way) to remove the battery from
    Samsung tablets with this method (I didn’t use auto-reboot, but trust
    your judgement). IF YOU HATE ANDROID 4.2.2,
    THIS IS *THE* METHOD TO DOWNGRADE TO 4.1.1: IT’S SAFE and the only
    time-consuming part is waiting for the firmware to download. That, and
    re-installing apps on non-rooted devices. PROCEED WITH DUE CAUTION, BUT

  142. Successfully downgraded TAB 2 [GT-P3100] to 4.1.2 without any issues…
    Thankz for the tutorial…

  143. As i am using P3100 how can i open back panel cover to remove battery like said in step 9.?

  144. Downgraded to 4.1.1. Jelly bean 4.2.2 has a terrible GUI for the tablet, compared to 4.1.1. Additionally, we found many apps didn’t perform well (NetFlix for one stuttered and stopped a lot), or crashed unexpectedly on the newer OS. Even if a factory reset would have fixed app issues (which we doubt) the GUI design is just horrible for this particular device, and whatever else 4.2.2 has to offer isn’t worth a problematic and poorly designed user interface.

    I’ll also add that step 9 (pull out the battery) is not necessary on this device, and leaving auto-reboot checked in Odin is also not an issue. You may want to mention that downgrading will remove root as well, but that’s easily redone.

  145. Hey. i need help fast. I have a galaxy s 3 with 4.1.2 on it and was trying to downgrade to 4.1.1, but i keep getting a fail. and I cant recover because it tells me to connect to kies, and kies wont recognies my phone now. so idk what to do.

  146. Thanks a lot for the help. I was able to get it going. Someone had to do a J-tag (I think it’s called) then reset it. Apparently the update (over the air) damaged the software itself so they had to repair it and then reset it. I’m just curious now that if I install the new version through Odin if my tab will be ok.

  147. Oh. I wasn’t able to select it. Right after my tab installed the updated firmware it got stuck on the “Samsung” boot screen. I tried to do the reset but when I even brought it up I saw in the background “No command” then the recovery screen came up. I can’t wipe the cache partition. I did the factory reset but when I did reboot the tab, in the background instead of seeing “No command”, I saw “Error” but it still rebooted.

  148. Ok. In the meantime, would the fact that I was unable to select the USB debugging option on my tab affect anything? Cuz my tab bricked before I could do any of that.

  149. Hi. I downloaded both the recent update and the previous version for my tab. I tried both firmware but it failed. I saw this message “Can’t open the serial(COM) port” even though I saw the “added” message in Pdin.

  150. hi, does this second error message clarify things because i”d really love to know what the problem is and if there is a solution to it

  151. sir please help me there is an other problem when ever i download any thing its pdf file or other else it shows start downloading but actully it doesnt …so what i do please help me sir

  157. HI Rajesh I have an S4 I337 and since i downloaded the latest firmware using the phone, the 4G&3G bands no longer connect my mobile data connects as Edge only by i can’t actually use it, it just shows up on the phone as an edge connection but there’s no internet. I have tried several methods to manually select the bands but if i select the lte band only for example I lose connectivity with the network. A month ago before my upgrade 4G connectivity worked like a dream, now I live in Trinidad but never had any issues with the phone before the update. I am trying to downgrade the firmware but i keep getting FAILED with odin every time and various versions of Odin. I do not know what to try again is there anything else that can be done to downgrade and get back my stock firmware?

  158. If youR device on Android 4.2 is rooted and has CWM, you can restore the backed up 4.1.2 after wiping Cache Partition, dalvik cache, and format system.

    In case you do not have root on 4.2.2, try this guide.

  159. Hi Rajesh I upgraded my grand duos from 4.1.2 to 4.2.2 last week..There was some incompatibility in my office reader…so I was wondering what to do..With this post I am confident I can downgrade to 4.1.2…I have take Cwm backup at that time shall, I restore it..when am I to do this wipe dalvik and factory reset. ? Please advice..

  160. i have a question, can we install another operator firmware for the same model of phone?

  161. i have a Galaxy S4 I9505, After installing a recent official update, my phone blocked when i try to call someone., Then i saw this thread, that’s how i solved the problem.
    Downgraded successfully to anterior version, and everything is OK, works like a charme !!!
    A very big Thanks Rakesh…

  163. Sir I searched it but i didnt get any solution …please sir if you recomemned me any app which you know that is better for me

  164. Hi Matt, sorry for the inconvenience. Actually the site has been under maintenance for a few days not. However, it is now opening and you can see the page. Due to DNS propagation delay, you might be able to open the link after a few hours. If you are able to see this page, that should open too.


  165. Sir please dont tell like this you have all problem solution soo please help me out i will be very grantfull to you

  166. Thanks again Rakesh, your replies to me are available to everyone else and I think they are as valuable as an article. The way I see it is that an article is an introduction of an idea and the Q&As that follow hold the key to learning a subject. I will look forward to the update to you articles and new articles. I carefully read your answers to other readers, because sometimes therein lie(s) the answer(s) to my questions.

    Keep up the great work !


  167. Hi Rakesh.Firstly Thanks for your advise. But I could not find any downgraded version (i was looking for 4.0.4) for Samsung galaxy S3 I9300 on the samsung-updates link.Can you please provide me with a direct download link for the download. I need to downgrade from android 4.2.2 to 4.0.4.Kindly advise.

    Thanks in advance.

  168. Hi Matt, there are 2 partitions on S3’s and most Android devices. One is the flash memory that contains all system files that constitute the OS and also other info like connectivity configuration, EFS/IMEI data and certain devblocks that keep sensitive files. The other partition on the internal memory is known as internal SD that is available for users. Additionally, you can insert a micro SD card to expand it for more storage.

    In most cases messing up with the flash memory, might make the device unusable and unrecoverable too for users and therefore even developers do not dare modify them. The commonest things that we modify are the system/apps and meta directories. This part contains files like apps and data and therefore it is easy to recover from an issue in case something wrong turns up.

    Smartphones have become alternatives for computers but the latter is a way ahead than its smaller counterpart. Moreover, every OS has it own limitations and as I said earlier, Android is not an exception. It has a BIOS like system that can be accessed through a set of secret codes that vary from model to model: http://droidviews.com/2013/some-secret-codes-for-android-phones-that-you-must-know/

    As for the ROMs post, I have not got time to update that but I’ll try to add more ROMs in a few days. To the best of my knowledge, the first ROM in the list “Jelly Beans’ is still the best. Try it and let me know.

    I would have written an article in the time I spent on answering, LOL 🙂

  169. Just use the above procedure carefully and you’ll land safe. You will find all required resources in the tutorial. For further assistance, let me know.

  170. Hi Rakesh. thanks for the info. I have upgraded my Samsung S3 mobile using odin to android 4.2.2 . but i need to downgarde it to 4..0.4. Can you please advise me the complete procedure for downgrading it !! and also please advise if the procedure you will suggest will be very safe…………..
    Thanks in advance

  171. Thanks again Rakesh. You are wonderful !

    A few more ambiguities that remain in my mind.

    What kind of storage medium do all the Android partitions exist on inside an S3, is it an SSD ? or flash memory ?

    So,at this point, there is no way to image all partitions inside a
    smartphone including the root access and boot loader into ONE image and
    restore that image ‘en bloc’ without having to restore root access /
    unlock boot loader FIRST ?

    Comparing with a PC, what is the equivalent of BIOS in an Android smartphone ? because in a PC, BIOS is the only item that exists as part of the hardware and is not imaged in imaging a system ?

    Empowered by the education from you, I am definitely going to root again and install a custom ROM to shut Verizon out. My concern about a Custom ROM is that you have posted your reviews of the Custom ROMs for S3. But that was how it looked like 5-6 months ago. How do I know which ROM is best at this point and
    how do I track the development of custom ROMs to make sure I always
    have the best one around ?

    Kindly advise.


  172. Hi Matt,

    I have used almost all platforms (except Blackberry) available for smartphones and and I come to realize that Android is the most flexible of all. However, I do not mean that it is the best, just better that others as it lacks certain things found on others or at least thing a smartphone must have.

    As for your concern regarding the full system image backup, it is already there but for devices with unlocked bootloaders and root access. If you have a Samsung device, there are a few more advantages, like availability of firmwares that you can install to restore your device in case anything goes wrong.

    Of all carriers, Verizon is one that sucks most because it tresspasses the common open source spirit by closing the environment. Belated updates, irritating bugs, unlocked bootloader, imposed updates against the users’ will- these make Verizon intolerable.

    The best way to escape Verizon’s tyranny is to root your device and then install a custom ROM that is closed to stock firmware. Also if you downgrade your S3’s firmware with a 4.1.2 firmware, you’ll not lose any data. As for rooting, we have a very easy one-click tool for SCH-I535: http://droidviews.com/2013/root-and-install-cwmtwrp-recovery-on-verizon-galaxy-s3-sch-i535-android-4-1-14-1-2/

    If you backed up the previous ROM, you can restore that after rooting. http://droidviews.com/2013/things-to-do-before-and-after-installing-a-rom-troubleshooter/

    Hope it helps.

  173. Hi Kane, I still have no news about a working bootloader unlock for SCH-I545. I’ll keep an on things and let you know if something new pops up. 🙂

  174. Hi Rakesh,

    Thanks for your excellent advice. I have a very basic question. Working with a PC if something goes wrong with the OS that cannot be fixed, a great option is to re-format the HD re-install the OS and you are back in business or use a backup image to restore 100% to a previous state. Why this does not apply to an Android phone ? Why we have to go into recovery, downgrade OS and what not.

    Why do the PC options do not exactly apply to an Android phone ?

    Is there not any PC software that can image my working phone/its entire storage/medium and I save that image, if Verizon does something to my phone like it sometime does, why can I not restore that image from backup by hooking up the phone to my PC and get my phone back, rooted phone with custom recovery just as it was before Verizon messed it up ?

    I say that because recently Verizon messed up my rooted S3 that had custom recovery and I had to go back to installing stock ROM and now I have an un-rooted phone and no custom recovery and I am scared to start the process all over again.

    Please advise.



  175. Hi Rakesh! I’ve been out of the loop but I just saw the root exploit for VRUAME7. I’m backing up my sd card so I can format it the proper way and try this. Any word on the progress for unlocking the bootloader on the Verizon Samsung Galaxy S4? I couldn’t find anything but I figure you’d know if someone was close.

  176. because the battery is dead as you say, we can’t suggest a way remotely. Your device must be able to boot into Download Mode to be able to do anything. Anyway, I’ll research to find out a way. We have our limitations, you know.

  177. Tried factory reset and cache wipe again. No luck. Device will not take a charge and battery is dead. I have tried two new USB cables (OEM) and two wall outlets and have tried charging via computer USB as well. Could this be a result of the firmware problem? Any ideas on what to do now?

  178. Hello again,

    Kies cannot connect to the device. It asks to reboot tablet to resolve issue, but tablet is in boot loop. I have done a factory reset and cache partition wipe with no success to stop loop.

    I have tried to reinstall original firmware via Odin. Although I receive a “Pass” message from Odin, device will not boot.

    Any ideas on what to try next?

  179. Are you sure you downloaded the correct firmware?

    Anyway, do this:

    Open Kies and click Tools > Firmware Upgrade and Initialization.

    Enter your device’s model name. This information can be found under the battery on device with a removable battery, and on the back of devices that have an internal battery. The device model number we are using in this example is SGH-T779. Make sure you enter the model number in all CAPS. Click OK.

    You will be asked to enter your serial number (S / N). The serial number is located near the model number. The serial number format will vary based on the type of device you are using. Do not enter your IMEI or MEID. Any letters in the serial number should be entered in all CAPS. Click Next.

    Then follow on screen options.

  180. Thanks for your prompt reply. I tried again (twice) with Odin3 v3.07 and the install hung at the same point as with v1.85. I can’t seem to get to recovery mode now…just gives me a message that firmware install had an issue and I should go into recovery mode with Kies.

  181. I am having Samsung S3 SCH-530 US Cellular piece and I did software update from baseband version MB1 to MD4 and andriod 4.1.1 to 4.1.2 but after the update my data services are not working tried everything but is not working pls help with a solution. Thanks

  182. Hi Bill, sometimes it happens. Boot the device in Download mode again and try with Odin 3.07.

    To boot it into download mode press and hold Volume down & power buttons. Let me know.

  183. Hello, I’m trying to downgrade to 4.0.4 on a Galaxy Tab 2 10.1 SGH-T779. I’ve followed the instructions precisely. The download via Odin3 v1.85 has frozen at this point:

  203. hey on my galaxy chat wifi and bt is not working.its just turning on…..please help me

  204. This worked for me. Downgraded my S4 M919v M919VVLUAMGI to M919VVLUAMGJ. My phone is from Wind Mobile Canada.

  205. Yes, I saw on droid-life & xda that there’s a bounty to unlock/root the latest version. It sits at $3200 right now. You should keep your loyal viewers updated on the progress.

  206. Thought I’d move this downgrading issue to the proper page. Dude, I am so starting to believe that downgrading ME7 is not possible (yet). I’ve read other people that are having the same issues. There is not a file besides the pure stock, that I’ve been able to odin or adb to my ich-515. I seem to recall that before, I had to do something to unlock the bootloader first but I can’t find that webpage.

    I have the samsung galaxy s3 with 4.2.2 OS which is not official! I want to downgrade it to previous firmware (4.1.2) ! It will work?

  221. Hello!
    I have the samsung galaxy s3 with 4.2.2 OS which is not so official! (I found it in youtube) ! I want to downgrade it to previous firmware (4.1.2) ! It will work?
    (Sorry for bad english)

  222. No, it will not. Just make sure you do not have both- Kies and USB drivers- installed at the same time. If yes, uninstall one of them. Also ensure that Kies is not opened while you do the drill. 🙂

  223. Okay, will KIES interrupt the firmware downgrade? I do not want to risk it, so what should I do? Also, what would happen if I tried and do this on a 20 percent battery? I do not fully see how it could use up the rest of the battery on a SGH-i317. This thing has a 3100 mah battery correct?

  224. Is there anyway to flash tar files from phone memory itself (sdcard), i want to flash ICS on to JB galaxy note but my phone connector is having issues and am unable to connect to laptop. are there any applications which can do this job without connecting to system? i have seen ODIN app on playstore, but not sure if it will do the job. please guide me on this

  225. thx ive done it and installed omega rom..but it still gets hot ..only when i play heavy game like vice city or asphalt 7 🙁

  226. im trying to root and put cwm now…do i have to factory reset before installing jeboo kernel or it is ok?

  227. With stock JB, yes it gets hot, but if you try a custom JB ROM, it’ll not make it hot. As for bloats, you can uninstall them yourself using a root file explorer.

  228. u know what..im going to install a custom rom…can you help me find one that look exactly like samsung jb but no bloatware or any other stuff that make it slow..and can u tell me what happens when i want to go back to stock?

  229. ye but with jb it gets hot ….with gb is not..and yep i think i should install a custom rom but i dont want to avoid my warranty..on my old phone i installed many roms but in this one i dont want because its new and expensive and i dont want to brick it..soo thx for help…one last question…is there any way to downgrade it to gb..? i know its old but i want to see if it gets hot…and if there isnt is there any way to fix my problem without custom roms? i can root..

  230. hi sir…i have a problem with my s2…it gets heated around camera..it has 4.1.2 and i want to downgrade it to 2.3.6 because i know it hasnt got that problem..its not any hardware problem but software,,,i got it about 3 days ago..( i know how to flash roms root and all that stuff..)soo can you help me and i want to downgrade it with nooo risk cause i dont want to brick it..

  231. i have a doubt please help me…at point 10: After flashing stock rom, without having recovery flashing on to mobile how can we reboot into recovery mode? am i missing anything, please guide me coz am deliberate to downgrade by samsung note (SHV-E160S, JB 4.1.2)
    dont we require to flash recovery?

  232. Hi, I’m on step 12. Wipe data/factory reset. After that it stuck at android logo with blue round is moving. It is take long time? Now about nearly 1hrs already. It is normal?

  233. S2 HD LTE, (SGH-I757M) Bell, failed to downgrade to from JB to ICS. I can’t boot into recovery mode, i get the message “Firmware upgrade encountered an issue. Please select recovery mode in Kies…”
    Please help!

  234. I have a question brothers .. I read in other post like this … where people give after flash with odin, it is inhibited midway, or terminates the process and the phone does not restart, or not re-enter download mode or restoration mode, or maybe all goes well but at want to go back and make flash with the new firmware, the laptop does not recognize the phone drivers, why this happens? I’m not happy with my service provider’s current rates, I want to change to another but for that I need root access and run a program to release my sim, and the program costs and apparently abuse exynos also need to make this program work .. If I change 4.1.2 to 4.1.1 I lose the ota updates? Some users report that using triangle no longer clears away flashs. I hope someone can help .. is complicated but I would lose my device forever.

  235. im at step 10 but i coudnt get to open my phone. im stuck at samsung logo… can someone help me please!

  236. just to be clear…. this does NOT require rooting my device right? because i reallly dont want to

  237. hi i cant get through to step 6. it wont post on the PDA. i click it a couple of times. can someone help me?

  238. Hey thnx a ton, I successfully downgraded back to my Custom ICS using this article…:) 🙂 I had updated to Jelly Bean on my samsung galaxy chat BT-5330….
    Thanks and keep posting…..: ):)

  239. This is brilliant, i’ve already got several apps from here, and any others I simply search around google for the APKs. So far I’ve managed to get almost everything I’ve wanted (plus more). Many thanks.

  240. I tried this, but sadly the install crashes and never finished; was worth a go though, thanks.

  241. I had to reboot 🙁 … that will teach me for 1.) Not backing up my data and 2.) Not reading from the beginning…

  242. You cannot go back. Try wiping cache partition only and reboot. If it boots normally, you will an opportunity to save your data. If not, God bless the world!

  243. I forgot to back up my data and am at step 11. Is there any way I can go back and back up my data???

  244. I have tried datela factory reset twice. Stil have the same problem. So ill try downgrading it.

  245. Hi have s3 with ice cream and upgraded it to jellybean and now I have problem with messaging. The message fails, and all message will be gone and need to restart for the message to comeback and work normally. I want to downgrade my samsung s3. Plss help

  246. Hahaha! No, my friend your phone is just fine! You missed unchecking the Auto Reboot in Odin. Anyways, remove back cover and pull out the battery and follow the steps 10-14. It’ll be fine.


  247. I did something wrong when I should open the recovery mode so my phone booted wtihout me resetting the phone, and I’m afraid something bad happened. It has been on boot screen for over 10 minutes now. Is it safe to interrupt? Or should I wait for it to finish?

    Should I worry about it being broken?

  248. I have a t-mobile note 2 that I want to unlock. Its on 4.1.2 and I realize that it needs to be on 4.1.1 to unlock it. Will this downgrade method work for me? Im a bit of a noob and dont want to put my device in any danger. thanks in advanced, Josh

  249. Hmm, I don’t really want to put a custom ROM on the phone. However I did manage to get gmail, youtube and a few other google apps working on the phone using the APKs found on the link you provided. I was also able to install the UK version of various widgets. No Google Play Store though :'(

    But otherwise I very good step forward 😀

    Many thanks for all your help,


  250. I did yes. I will uninstall it and try again when I get back from work in an hour, update back here again then.

    Thank you for all your help though, shame it didn’t work 😛

  251. I am thinking that it may be easier to sell this one and get a English one, either that or try make do with the lack of features and google play store. 😛

    Download and extract this file- http://d-h.st/GqD

    Click on PDA in Odin, select firmware.
    Click on PIT, and select the PIT file.
    Also check Re-Partition on the device.

    Then click on Start. Let me know.

  254. Thank you for the extra download links, however I still had no luck. Both resulted in the same output log and a big RED failed error 😛

  255. lol – No idea, but it was worth a go.

    Thanks for the links, i’ll give it a whirl in a moment.

  256. Another few forums suggest removing sim and sd card when doing it, I just tried this and got the same result.

  257. I tried Odin3_v3.04 first and then Odin3_v1.85 the second time around. The log above was from Odin3_v3.04.

  258. FYI – I also tried downloading the same firmware version but from a different website on the second go; also a no go.

  260. Hi Shane,

    As long as your device model is GT-N7100, you can install the UK or any unbranded firmware.

    1.The failure thing often pops up due to some mistake on the side of users. If you are careful and do things with a cool mind no damage will be done. In case, anything wrong takes place you can install the previous firmware back.

    2. As for the OTA update, you’ll not get it because you phone has Chinese modem. You will have to update it manually.

    3. Yes you are right. Install this firmware (the steps are above): http://hotfile.com/dl/202534596/abbc6f4/Samsung-Updates.com-GT-N7100-BTU-N7100XXDMC3-1364348323.zip.html

    Good luck and cheers!

  261. FYI – Just in case it wasn’t obvious, I am not looking to downgrade or upgrade, purely install a firmware appropriate for my region of residency. 🙂

  262. I have a Galaxy Note 2 (GT-N7100) which was a gift from my father-in-law. Because I am a British citizen and reside in the UK the phone he gave me (bought in China) has a Chinese region firmware installed; because of this it is lacking a lot of the main features I would want and use regularly.

    I contacted Samsung to see if they could install the firmware for the UK region, sadly they said they can not and would not. Therefore my only choice is to install the firmware myself, therefore I have three very simple questions that I wanted answer for before I continued…

    1. If the installation fails, can the phone be reset back to its original state without issues? (Otherwise I will have broken a brand new, expensive gift).

    2. If I install a firmware myself, will the phone continue to update automatically to newer versions for the firmware, or do I need to manually do it each time?

    3. I wanted to ensure that I was installing the right firmware for my region, I have a Galaxy Note 2 (GT-N7100) and will be using it in the UK region with Orange/T-Mobile (the combined one they offer). I think I need the firmware with the CODE BTU, can you confirm I am right?

    I thank you very much for your help, and if I do install the firmware I will report back its success.


  263. Download the appropriate firmware zip and extract it to get the file with .tar.md5 extension,
    If you have problem with finding the firmware, give me your phone model, carrier and country.

  264. Hi, can someone tell me where do i get this file from (firmware file in tar.md5 format) thank you

  265. thnx a lot for this tutorial, just wanna let you know that it worked fine for me . I downgraded the s3 of a mate of mine from android 4.1.2 to 4.1.1 without any problems . Since than no problems with his phone anymore. You made somebody really happy. Thnx a lot again.

  266. Bad news boss. Hotfile only allows me to download for 30 minutes, and it cuts it off as soon as I’m halfway..

  267. Sorry I’m pretty noob at this kind of stuff. How would I do that? Which files do I need to download, whats the methods afterwards?

  268. The options showed in method for 4.1.1, some of the options don’t appear to the 4.1.2.. Which doesn’t allow me to unlock the sim.

  269. The method you showed me is on the 4.1.1 Firmware, and I am currently on 4.1.2. Is it necessary that I have to downgrade it to follow the procedures?

  270. I have a Note 2 LTE, not sure if locked to Telstra (Australia) or not. Because whenever I put in a sim, it says ‘no service | | Emergency calls only’ so I’ve decided to try downgrading it to 4.1.1 so I can manually unlock it. I doubt the phone is hardlocked. Any recommendations of firmware, tutorial forums, etc?

  271. Followed the steps and it worked, Just a question and idk if you would know the answer to, im dowgrading to 4.1.1 so i can unlock my phone to use a different sim card, can i upgrade back to 4.1.2 and still have the phone unlocked or do i have to keep it in 4.1.1 now

  272. Hey, i have always needed help finding a stock ics rom for my region: Denmark(XB) , hope you can help 🙂

  273. hmm~ i still have some question, if i downgrade my firmware to 4.0.4, if next time, i would like to update back 4.1.2 through samsung automatic update, is it possible? or must use this method to update for next time?

  274. BASEBAND: I9300DXEMB1

    If i use wrong REgion does effect anything?

  275. i would like chg my Samsung Galaxy S3 from 4.1.2 to 4.0.4. is it an risk? my build number (I9300XXEMC2)

  276. Hi,

    I apologize for being a complete n00b with this stuff. I hope you can help me. I had a perfecting working fine ICS on my Galaxy S2, but after the upgrade to JB the battery drain is immense. Instead of lasting more than a day with frequent use it’s now over in about 4 hours of moderate use. So I’m desperate to get ICS back.

    My model is GT-I9100 and I live in The Netherlands. However I can’t seem to find the right downgrade firmware. Can you be of any assistance?

    Many thanks in advance,
    Van Dattum

  277. oh and I’m trying to downgrade since every code I enter its on “not registered on network” Can you help me locate the appropiate firmware. buid number. JZO54K.T999UVDMD5

  278. Could you send me a link for the 4.0.4 ics firmware? I’m from the Philippines and baseband version is I9300DXDL15. Please. 🙁

  279. hey i did try to follow them… when i press the volume up + down + power it vibrates once and then then it comes back to the odin screen showing that message it has encountered an issue.. i tried doing it 3 times still the same

  280. i tried downgrading from JB using the ROM given above which is UCFL6 but when i reboot it gives Firmware Upgrade encountered an issue… what should i do now?

  281. Hi sir.I dont have the avoid poor connections and WiFi frequency band option. What remedy do I have?

  282. I would advise you to reset the WiFi connection and then remove the WiFi connection information from your device. Then try and connect again.

    I own multiple devices and it is always subjective while it comes to connecting to WiFi.
    Also, make sure that under “Advanced” in WiFi settings you have set the following:
    1) Set “Keep Wi-Fi on during sleep” to “Always”
    2) Untick “Avoid Poor connections”
    3) Change “Wi-Fi frequency band” (if any) to “Auto”

  283. WiFi sir. It just keeps on connecting. But when I am at the door next to the room where the WiFi is, it connects immediately. But on my nexus, it connects even if I am at my room,m.:(

  284. Hi sir. I decided to downgrade again to ICS permanently. 4.1.1 isn’t working for my WiFi. Could you send me a link of the firmware 4.0.x? I’m from the Philippines and baseband version is I9300DXDL15. 🙁 really frustrated. 🙁

  285. hi. i did it again the second time. But the connectivity takes forever. But it detects that it’s signal is strong. Any thoughts?

  286. I will try later. I thought of things thru. I managed to install the Samsung drivers but I failed to download the Kies. Should it be both be installed before i downgrade? I just successfully installed the Kies after my downgrade though. Is it possible that this might be the culprit?

  287. Look, the method given above has been fully tested and working fine but the success also depends on the fact how you do things at your end. Try again to flash the firmware.

  288. I also read at a different forum that they downloaded a modem.bin for the new software. Will this work? and if does, do you have a detailed instruction on how to do it? last time i was using 4.1.1, i didn’t get any problems with my wifi. Im really getting frustrated with the wifi issue.

  289. how will i know? like if it is locked to a specific phone carrier? No. when i bought it, it is open line.

  290. and after some time it ends up being disconnected. I did all the steps right. hmm. should i still downgrade? the original version of this was a 4.0.x i couldnt remember the last digit.

  291. sorry. i successfully downgraded it to 4.1.1. But when i connect it to the net, the connecting to the net takes forever. How come?

  292. Help.

  293. Hi sir…
    Are this method can be use to downgrade my galaxy nexus i9250 from JB 4.2.2 to ICS 4.0.4? T

  294. You have too many questions but it sounds natural for a newbie. Did you backup the original ROM before flashing CM? If yes, you can restore it. If no, you can flash new firmware and it will fix everything. You told me everything but not about the device.

  295. Hi!

    My phone been put on Cyanogenmod 10.1 nightly with the same kernel revision. This rom is based on Jelly Bean 4.2.2. I would like to go back on stock Virgin Mobile Canada firmware which is based on Jelly Bean 4.1.2.

    My friend who put Cyanogenmod 10.1 told me that he was forced to upgrade the radio network settings for Cyanogenmod 10.1 to work. If I go back to the stock Virgin Mobile Canada firmware, will I break the radio network settings on the phone which would prevent me from placing or receiving phone call’s? Also will the firmware put back the original CSC, PDA, PHONE and kernel?

    I am not able to connect to the phone using odin since Cyanogenmod 10.1 been installed on my phone. The usb debugging mode is active on the phone and I can see it using the command ADB /devices. I have Samsung usb drivers installed on the PC but it does not seems to fix the problem. It looks like Cyanogen is based on a Europeen Jelly Bean. Is there a specific driver that I can download to fix that?

    My only option left is to use clockworkmod as a recovery option and install from zip. Can this be done if I cannot get odin to work?

    Thank you for everything.

  296. I have Note 1 with the updated jelly bean. but the latest android seems not very compatible with galaxy note 1. my phone is just irritatingly laggy! thanks to this tutorial I’m back to ICS 4.0.4 and my note 1 is again running faster than the speed of light. thank you mr. rakesh shukla

  297. I cant see mine. upon checking my setting, here is my base band version i9300XXELKB? pLEASE HELP. Im from th philippines

  298. I have GT-I9305 LTE with EE. Followed the steps, no probs !! Downgraded to 4.1.1 Many thanks mate

  299. Thank you so much once more. I wish I could at least shake your hand 🙂
    I successfully installed the 4.1.2 unbranded version you gave me and it works perfectly. No more bloatware, no more T-Mobile splash screen and my WiFi works flawlessly. I couldn’t be happier.
    Thank you once more.

  300. The reason why I recommended ICS over GB is that if you try to go to GB from JB, you phone might not boot because GB lacks bootloader. I still suggest, try to roll back to ICS. I have used ICS on my S2 and its worked fine.

  301. sir what if I downgrade jb to ics first .. then from ics to gb? multiple steps. cause I read above you said you did the galaxy s2 from ics to gb. and adviced me to downgrade from jb to ics. what do you think it might work?? :DD please help me. thanks so much sir.

  302. galaxy s2. I want to go to 2.3.6 or 2.3.5 or 2.3.4 as long as itd gingerbread. can I flash like when I upgrde it with odin? why ics? I really want go back to gb. thanks sir

  303. I want to Downgrade my Samsung S2 GT-I9100G To 2.3.6. I’ve got some PDA fIles But I can’t successfully Downgrade it So I need Help Here .When I start The Downgrade Process through Odin It got Hooked up in the Modem Section.
    This is the PDA file I’ve Got here: GT-I9100M_BMC_I9100MUGKG2_I9100MUGKG2_I9100MBMCKG2

  304. Hello again. I bought the phone contract-free from a store here. I live in Romania and I’m guessing they imported the phone from Germany. The I9305 is very very rare here so this might be the reason.
    I looked over on Samsung-updates and the only firmware I could find for Romania is one 4.1.2 for the region CNX. This means Vodafone Romania. I’m guessing this is a Vodafone Romania branded firmware?

    Could you please recommend an unbranded firmware I could try? I use the phone with english language so language isn’t an issue. I just want to get rid of the T-mobile bloatware, and T-mobile splash screen at boot and shut down.

    Also, if you could please link me with a 4.1.2 version and a 4.1.1. I would like to try 4.1.2 first and switch to 4.1.1 if WiFi fails again.

    But before I do any of this, do you have any idea if this will void my warranty? I’m guessing it won’t.

    If I encounter any issues during installation, I can always reboot in Odin Mode and reflash the firmware I have right now. Is this right?

    And one more thing I don’t understand if you could explain in a few lines, or link me to an article: How does the region influence the firmware? I understand if it’s branded, but if it’s not branded, then how does the region change anything?

    Thank you for the time and sorry for the numerous questions. I’m new to this.

  305. Nice to know that! If it is not SIM-locked, you can install an unbranded firmware for your country/region. Just make sure the phone model number (GT-I9305) is the same. If you need any other assistance in the matter, feel free to ask.

  306. Hi. I tried it yesterday and it’s really easy and seems safe (I did some more research on the matter). I successfully downgraded to 4.1.1. So go ahead. Just make sure you follow the steps perfectly. Good luck

  307. Hi. Sorry for the very late reply. Thank you so much for your reply and everything. I followed your steps yesterday and I’m now running 4.1.1 on my I9305 and my WiFi is working like a charm again. Your tutorial was perfect. Thank you so much.

    I tried version 4.1.2 first, but I had the same issue, so I installed version 4.1.1 and everything is perfect.

    I really hope version 4.2.2 will fix this.

    I do have another questions if I may:

    How can I unbrand my phone (it’s not sim-locked….just T-mobile branded)? I would like to get rid of the bloatware and install an untouched version of the firmware. Do I have to root my phone? I have uninstalled everything I could and disabled the rest. I suspect this would definitely void my warranty. Also I’m thinking that maybe installing a different version of the firmware (4.1.2) would maybe fix the WiFi issue. What are the limitations of the firmwares I can install with Odin on my phone? I don’t quite understand the region limitations.

    Thanks again

  308. sir I updated from gingerbread 2.3.4 to jelly bean 4.1.2 . and I just want to go back. reaally dislike jb. can I downgrade it? what do I need to do it? I read below about bootloader etc?
    please help me. thanks before sir.

  309. Got stuck in Odin while flashing stock rom(GT-S5360-INS-S5360DDMD1-1366435267) on Galaxy Y S5360. The device was detected by odin, when i started flashing, it got stuck on SetupConnection. Finally i unplugged the phone.
    Plz Help.. i’m currently using Beautysense V1.0 custom rom..

  310. Thanks it worked to some extent.. Another thing i noticed was if i uncheck Do not keep activities, it works fine without lag else there is a small lag..

  311. Got stuck in odin when i tried to install stock firmware(Samsung-Updates.com-GT-S5360-INS-S5360DDMD1-1366435267) on Galaxy Y S5360..
    The device was detected in odin. When i started flashing it got stuck in SetupConnection so i unplugged the phone.
    Plz help.. I’m using a custom Beautysense V1.0 rom presently..

  312. Hello Sir..
    I’m using Galaxy I9300, Rooted GB 4.1.2. I’m from India.
    I’m unable to connect to Leap Wi-Fi network in my office. Is there any patch for this in jelly bean itself or I have to revert to ICS?? Also i found some MSG n Contact lag in GB despite using Seeder..
    Plz Help..

  313. Do not give that guy a single penny. Just follow the tutorial above an you can do it yourself whether you are a tech-guy or not. You can flash the original firmware yourself. Just tell me about your carrier, if any. May be it is Claro!

  314. Hi! i wanna go back to ics from the upgraded jbean on my s2…here in Argentina…a guy-tech says he ll do it “flashing” it for 30 euros….and says there are no risks etc………..Is this so?? will he put the ics that had the phone in it or he will add some from his pc…he says is the original….?? i want the original because the music player (it is louder than jbean) thks!!

  315. Hi Alex, it’s really bad that Samsung took away ripple LS. Whether they’ll add it in the next update or not, depends on them. I think if they have deactivated it once, it’ll not come back.

  316. Sir is there any other possibility to get back the ripple effect on the lock screen after updating my s3 mini from 4.1.1 to 4.1.2? I really loved this feature and it’s sad that it was deactivated. Do you think they will activate it again in 4
    Thanks alot

  317. Hi! i updated yesterday my galaxy s2 gt-i9100 from 4 0 to jellybean 4 1 2..and i hate it!!!…can i go back?

  318. As for the EMMC brick it is most common to certain ICS (4.0.4) firmwares for Galaxy Note and S2. However, Samsung later fixed it by an update. The bug is reported to show its face when a custom kernel is flashed or the device is factory reset.
    I know several cases of people successfully flashing downgrade firmware on Galaxy S2 and I think it should work for you.

  319. I was finally able to complete the process today, thank you for your help! It’s greatly appreciated!

  320. when odin show pass my phone screen displays” Downloading…Do not turn off target!!” ..what step should i do now? is it step 8

  321. That’s why we warn users to be careful. Anyways, pull out the battery, place it back after 40 seconds and then follow Steps 10-14 from above. It should be fixed.
    If it still does not help, reinstall the firmware more carefully.

  322. downgraded note n7000 4.1.2 to ICS 4.0.4 and accidentally checked Auto Reboot and unchecked F:Reset Time…still odin manage to show Pass.. but then my phone stuck on Samsung Logo and blinks on forever..what should i do now.does this means my phone is unrepairable..even with the samsung service centre technicians..reply fast..

Pull battery, start over? Been in the same process for a half hour. How long should the download usually take?

  332. hi, rooted my phone don’t know the next steps to downgrade from 4.1.2 to 4.1.1 tmobile note2 t889, please help

  333. i’ve tried with the newer version of odin and all worked fin until last reboot then the phone says no app available and its like android as never been installed on the phone so i returned it to my carrier Thx for the help

  334. No problem on the delay. It kind of forces me to figure things out and I thinks that’s the best way to learn on these things. I have a SCH-I535. I got that issue solved. I think I have that resolved more of an issue of inpatients. I am still having an issue with the camera on carbonrom 1.6.1 not connecting. Is there a way to uninstall the camera app then reinstall it?

  335. Try this again- dial the following keys *#197328640#

    Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data Initialize ….. wait for a minute then reboot your phone… enjoy!!! There is no confirmation on the phone that the unlock was successful…. just reboot your phone….

    If it does not work, contact the person/carrier from where you bought the unlock code.

  336. This line “Can’t open the serial(COM) port.” from the log indicates that there is problem with connection. Possible fixes: Reinstall the drivers, close/remove Kies temporarily, check the USB cable connection, turn on USB Debugging in case you forgot and also reboot both- the PC and phone.

  338. I recently replaced my Verizon gs3 with a new gs3. This phone has been a pain to root. I flashed it back to stock using the link you provided to 4.1.1. The last step after flashing stock rom is pull battery and boot into recovery mode. When I boot into recovery I get “SAMSUNG” an unlocked padlock and “CUSTOM” I don’t remember seeing this when I flashed my last gs3 to stock. Is this normal? If not how can I fix it.

  339. I have a Note 2 sgh-i317m and i purchased an unlock code and have done this for a few smartphones so i have a good idea of what im doing but for whatever reason the keypad codes that i need to enter so i can input my code doesnt respond. i use the *#06# that responds fine, but it seems any other from the tutorials just dont work, is there different commands for this version of the note2, id also like to add that there was a tutorial of how to unlock the NOTE2 through the *#197328640# although that command works to get into the menu there was an option that wasnt there, im on jb 4.1.2

  340. i have a question can i use this method to downgrade my galaxy s2 from 4.1.2 to 4.0.3 ??
    and if i want to go back to GB 2.3.5 do i have to use the bootloder file ?? and if i do where can i download them ??

  341. Thanks! it worked!

    I’ve downgraded to 4.1.1. and got my phone unlocked watching how to unlock note 2 free.
    I’m not sure if it’s unlocked cause I don’t have any other sim card from other carrier.
    If it’s unlocked, is it the exact same condition as unlocking with the unlock code?
    and I heard that unlocked condition would stay the same even I upgrade back to 4.1.2.
    is it also true?
    I got my data backed up however I can’t restore the applications. I guess it’s because my phone is on 4.1.1 so it won’t restore the application back up from 4.1.2.
    I can’t wait to test the unlock and restore everything.

  342. Hi I am using a galaxy nexus and using 4.2.1. It sucks and I want to downgrade it to 4.1.1 again. The problem is I couldn’t find the firmware. I am using Samsung galaxy nexus GT-i9250 from Hong Kong.

  346. There is nothing to be scared. The method is safe if you do it carefully. Try the Steps 10-14 from above. Do not charge your device until it is deep discharged and plug the charger after turning the phone off. You will hopefully see the difference.

  347. i want to downgrade just because battery life decreased,is it worth to take risk and downgrade or i should just wait for the next update ? everything works well on my device i am scared of what can happen

  348. i have the galaxy S3 i9305 i did the same as you hahaha i upgraded but i have no issues with wifi i want to downgrade just because the battery life decreased with the new update, please tell me if you had anu troubles downgrading your firmware i am scared too

  349. I upgraded my Samsung I900G to JB from ICS but when i tried to downgrade it to ICS again using the above procedure my Phone is not booting up into recovery mode, its stuck in S sign window. Please help me

  350. Some possible reasons:
    First of all make sure USB Debugging is turned on. Then check you have not installed Kies and Samsung USB drivers both (if yes, try removing Kies). Also that the firmware you download matches your country and carrier. You can also try rebooting the phone and PC.

  351. Hi, the WiFi bug is a known issue with all 4.1.2 updates for Galaxy devices.

    1. Since you’ll replace an official firmware with another, it does not increase the custom flash counter. As for the warranty part, it’s a disputable part. I have able to claim warranty in my case though.

    2. Yes, all firmwares are not the same and I believe Samsung must be aware of the bugs that concerns millions of its users. It should be fixed.

    3. We do say that it’s risky to do such things manually but they are actually not. I have done it hundreds of time over the years. The biggest punishment may be a bootloop and we have a fix for that too. But if you are careful, nothing wrong will happen. I will be here to help you in case of any such occurance.

    4. You can manually download the latest firmware for your phone and it might fix the issue. Download both the firmwares (4.1.1 and 4.1.2) Try the 4.1.2 first and perform the Steps 10-14 from above guide. In case that doesn’t work downgrade to 4.1.1.

    5. Here is the firmware file for Germany (T-Mobile):

    4.1.1- http://www.hotfile.com/dl/175467127/a627273/I9305XXALI7_I9305DTMALI4_DTM.zip.html

    4.1.2- http://www.hotfile.com/dl/188299559/52dd2d1/I9305XXBLL5_I9305DTMBLL4_DTM.zip.html

    Hope it helps you

  352. Hi. I bought a Galaxy S3 I9305 last week and when I got home, I let it update from 4.1.1 to 4.1.2. Immediately after that, my WIFI couldn’t connect any more. It takes me around 5 minutes of continuously turning the wifi on and off to connect to my router at home. I’m seriously starting to consider downgrading. But having never done this before, I am a bit scared and I would like to ask you a few questions:

    1.My biggest fear is if this will void my warranty. I know it has a flash counter. Will flashing the 4.1.1 stock firmware (I assume it’s stock), increment it?

    2. I was thinking of maybe waiting for the 4.2.2 update. Do you think there’s any chance that will fix it?

    3.In case something does go wrong while flashing. Is there any possibility to end up with a completely bricked phone? Like not being able to do anything with it after that.

    4. If I flash the 4.1.1 firmware and then let it update to 4.1.2 again, is there any chance the wireless will work properly that time? I imagine not all S3 phones have issues with wifi after the update.

    5. And lastly, I cannot find my firmware in the link you provided. I have the I9305XXBLL5 DTM and I can only find the 4.1.2 version.

    Thank you so much for taking the time to write this “How to” and answering to our posts.

  353. i dont know in which way i should convey my thank you,cause your post has helped me enormously. i upgraded to JB but it did not worked (region TCE).with your help i roll back to GB 2.3.6.
    and also thanks to samsung update -firmware archive from where i downloaded the downgraded version.
    now help me once again,please let me know the indian JB version 4.1.2 for my galaxy s2 GT-I9100.

  354. Ok thank you! I’ve tried everything to avoid the downgrade, but wifi problems still occurs, and yesterday I got the “authentication error” message, which took me about an hour to solve. I’ll try with the 4.1.1 firmware, and if it doesn’t work I’ll install the ICS, which is the one that was installed when I bought it.

  355. GT-i9300. In Kies says region is ARO. The problem is when is look for the firmware in samsung-updates I find the one for ARO Region but the “Version” column says I9300UBDLJ1 (for 4.1.1) and I9300UBBLG2 (for 4.0.4).

  356. Hi, I’d like to ask you which is the software I should download to my phone. In “Base band version” it says I9300UBELL1. The phone is factory unlocked and from Argentina.
    Thank you!

  357. Hi Rakesh,

    Its been about 2 weeks since I upgraded to Jellybean and the problem of battery life dropping has been only aggravating. Sometimes the phone switches off even in the middle of a call. I had read quite a few reviews on the effects of upgrading to ICS from GB, with lots of users commenting on the loss of battery life and consequently wanting to move back to GB. Wanted to check with you if there are similar issues with JB, especially on the GT N 7000.

    Also, can you let me know what apps are there which generally lead to a huge drop in battery life.


  358. Thank you!!! Everything worked as described with your link to the firmware for my device. Although I will miss the nicer Gallery interface in 4.1.2, but I am more productive using 4.1.1. Cheers! 🙂

  359. Hi Arnab, I really see no wisdom in sticking with a lower version firmware when the latest with great features is there. If by recently you mean 2-3 days, I would recommend you to let the device complete it 3-4 charge-discharge cycles. By this I mean, charge the phone fully, and then do not plug it till it’s fully discharged. Repeating this for 3-4 times, you’ll see a great difference in battery performance.

    This is very necessary that the Li-Ion battery and your phone’s new software sync and tune up with each other. In case you problem is not solved after doing this, I would suggest you to root your device and install a custom ROM.

    Here is the link to all required tutorials: http://droidviews.com/tag/samsung-galaxy-note-gt-n7000/

    Just browse a few pages. Hope it helps you and thanks for visiting.

  360. Hi Rakesh,

    I am using a Samsung Note GT N7000 and had recently upgraded to Android 4.1.2 Jellybean. On doing so, my battery life has halved from a full day to a half day. First I would like to check with you if this is normal and whether there is a way around this problem. Otherwise, if I need to downgrade to a lower version of Android, could you suggest what version should I go for. As I have never done this before, could you guide me to a site or resource which can help me with the same.


  361. Urgent!!! My phone’s (galaxy note) screen flickering frequently and automatically
    shut down itself. I found this problem after few days when the phone has
    been updated to Android Jelly Bean 4.1.2 version. What is actually
    happening to my phone? Whether there is software issue or battery

  362. Hi, need help. I want to downgrade my S3-LTE (GT-I9305) to 4.1.1 mainly due to Cisco LEAP wifi connectivity issues. However, I cannot find the firmware for my phone. The region code is XSP according to KIES. Thank you.

  367. Hi, I’m on the 3 Network in Austria. Samsung Galaxy S3
    I need to downgrade from 4.1.2 to 4.1.1 – but cannot find the 4.1.1 ROM file – any chance you could find it?

  368. My galaxy S3 I9300 keep freezing & the battery draining out super fast after I had updated to 4.1.2. Sometimes it’s feezing bout 5 times in 1 hour. Can you tell me what should I do ??? urgent 🙁 TQ

  369. That worked brilliantly and I can now connect effortlessly to WiFi, I can’t thank you enough.

  370. Thank you for your superb response time – as soon as it’s downloaded I shall give it a go!

  371. I am about to try a downgrade from 4.1.2 to 4.1.1 on my Galaxy S3 LTE I9035 but I can’t find a 4.1.1 firmware which matches my CSC code. My CSC code is EVR and on the Samsung Updates site the only firmware available for EVR is 4.1.2. I am having horrible WiFi issues and our baby monitor uses WiFi so I am unable to watch our little girl so am very keen to see if going to 4.1.1 helps. Do you have to use the firmware with a matching CSC code or could I use another one from the same country (UK)? Thanks very much for all of your kind help.

  372. Hi, I find your website very helpful so I just want to know, Can I upgrade my Galaxy S3 International version(Philippines) Jellybean 4.12 TO —> 4.2.2 US version instead of downgrading. because after 6 months of using it my S3 is giving me too much head ache it keeps on freezing and restarting after 5- 15mins of using it. mostly when using Bluetooth, Messaging , Facebook and Camera. I’ve been looking for answers about this international issue with S3 but I still can’t find any solution. Please help. if you could please email me at [email protected]

  373. That may be a possible reason and can be fixed too. I guess another possible reason might be the absence of a Modem in the leaked ICS ROM. That might also create problem.

  374. These days i gived the phone to a Phone service and they said it is a problem with chip flash from the mainboard

    what it’s your opinion?

    it can be rapaired or not?

    waiting for your reply…

    thank you!

  375. Thank you very much.. this worked for me on my Samsung S3 had to downgrade it from 4.2.1 to 4.1.2 due to several issues with Messaging

  376. My S2 phone have already downgrade from 4.1.2 to 4.0.4. Everything is all right, but the Messaging button is something wrong. It always get wrong when I press in. It can’t sent message and receive message again. What should I do now…….Also, thank you for your detail steps on downgrade android.

  377. I need to downgrade my 4.1.2 to 4.0.4 so i firstly need to downgrade so then i need to root? right?

  378. ok but i have one question,i need to do downgrade now so i need to downgrade my software,and than i need to root right?

  379. so i just need to root my tablet? and it will disable my auto updates? is there any tutorial how to root my tablet? is it good?

  380. it isn’t i can’t disabe it i just can update it.i’ll downgrade android tomorow but i could’t find it when i first downgrade,so i can disable using kies? could you explain me better?

  381. but i don’t have that option in 4.0.4. i have only that option in the 4.1.2 but i hate 4.1.2 so is there any other way? i’m pissed i did downgrade once cuz it updated and now again :S

  382. Go to Settings> about> software update, tap on menu button and disable it. You can also disable it from Samsung Updates.. If you are using Kies, you should disable software update from there too. I am using custom ROMs for a long time so I do not exactly remember the settings but it should be there.

  383. I have a question how can i disable auto update on Android 4.0.4? i did downgrade ,and again it auto update my software.
