The one-time Samsung’s flagship, the Galaxy S4 is quite an old device now. The phone was released with Android 4.2.2 about 2 years ago and things have changed drastically since then. The Android OS has witnessed the greatest update since its evolution in the form of Lollipop. It might sound surprising to you that only 3% of all Android devices have been fortunate enough to rock the new software in the last 6 months. The Samsung Galaxy S4 Active is really lucky to get the Lollipop update despite being so old now.

The AT&T Galaxy S4 Active (SGH-I537) started receiving the Android 5.0.1 Lollipop OTA with build number I537UCUCOC6 just a couple days ago. Most users of the phone might have already got the new update but if you have been able to get the OTA for some reason, or just did not take the Lollipop update for fear of losing root privilege, our today’s tutorial is just for you.

Whether you want to just enjoy the stock Android 5.0.1 Lollipop without root, or you happen to be one who can’t live without root, we got a detailed guide to help you get what you wish.

Install Lollipop OTA on AT&T Galaxy S4 Active (No Root)

Note:

To be able to install the Android 5.0 Lollipop OTA package on your AT&T Galaxy S4 Active, your device must be fully stock (no root) with Android 4.4.2 (NH3) firmware running on it. You can check your firmware and build version under Settings> About on your device. If your S4 Active is on a lower firmware version, download the NH3 firmware from below and install it. Then flash the NH3 OTA package using the instructions given below. You can then install the Lollipop OTA. Flashing the OTA will not wipe your phone’s data!

Download Android 4.4.2 NE3 Firmware: SGH-I537UCUCNE3_v4.4.2_ATT_ALL.zip

Firmware Installation Tutorial: Install stock firmware on Samsung devices

Download NH3 OTA package: NE3toNH3.zip

→ Having downloaded the OTA zip package (NE3toNH3.zip), unzip it. Open the extracted folder to find 2400258.cfg. Rename this file as update.zip and copy it to the external SD card of your phone. Install it via stock recovery (detailed steps below)

Installing the OTA Package

  1. Download the Lollipop OTA package: NH3toLollipop.zip (972MB)
  2. Now extract the downloaded zip and unzip it. Open the extracted folder to find a file with .cfg extension. Rename the xxxxxxx.cfg file as  update.zip and copy it to the external SD card of your phone.
  3. Enable USB Debugging on your phone as a precaution.
  4. Turn off your device and reboot into the stock recovery. To do so, hold the Volume Up+Home+Power keys together while the device is switched off. As soon as you see the Samsung logo, release the Power key and keep the other two keys pressed until you see the recovery menu.
  5. Using the volume keys, scroll to apply update from external storage option and select it by pressing the Power key.AT&T-Galaxy-S4-stock-recovery
  6. Navigate to update.zip package and select it.
  7. Confirm installation when prompted.
  8. When the file is flashed, go back to the main menu and select reboot system now option.

Done! Now you need to wait patiently for about 5-10 minutes and when your AT&T Galaxy S4 Active boots up, you’ll have Android Lollipop on it.

Install Lollipop on AT&T Galaxy S4 Active & Keep Root

Note:

The procedure will not trip the KNOX Warranty Void counter but it will wipe your apps and data present on the internal storage of your phone. You can use Titanium Backup or similar apps to back up your data. It’s a good idea to backup everything before proceeding. No base firmware is required to update your AT&T Galaxy S4 Active to Lollipop using the FlashFire method given below. You can install the pre-rooted firmware regardless of what Android or firmware version your device has. However, your device must have root access as FlashFire requires it. To root your S4 active on the 4.4.2 KitKat firmware, you can use Towelroot.

Preparations

  • Enable USB Debugging on your Galaxy S4 Active. This step has nothing to do with the method given below but it could be a lifesaver if anything goes wrong.
  • Install Chainfire’s FireFlash app on your AT&T Galaxy S4 Active. Since this new app is only available for beta-testers currently, go to the Google+ page and join the Android-FlashFire community. You must be signed into Google+ using the same Gmail ID that you use on the Google Play Store. Having joined the community, click the Play Store link to download FireFlash.
  • Download the stock rooted Lollipop firmware for the AT&T Galaxy S4 Active: I537_OC6_Stock_Rooted_ROM.zip
  • If you also want to enable WiFi Tethering on your AT&T Galaxy S4 active, download this file too: I537_OC6_TetherAddOn.zip
  • Backup your apps and data.

Instructions

  1. Open SuperSU app, tap Settings and check Enable su on boot option.enable-su-during-boot
  2. Copy the I537_OC6_Stock_Rooted_ROM.zip to your device.
  3. Open the FlashFire app and Agree to the Terms and Conditions prompted by the app.
  4. Press the rounded “+” button twice to bring up the Actions menu.fireflash-app-android
  5. Tap Flash Zip or OTA option and select the I537_OC6_Stock_Rooted_ROM.zip.
  6. Make sure that Auto-mount is unchecked under the Options menu and press the checkmark to continue.
  7. From the main menu uncheck all options under EverRoot and use default Reboot settings.
  8. When all’s done, tap the Lightning bolt icon followed by OK to begin the installation.

The screen of your phone will turn black for a while and then show the contents of your device before initializing the installation. Just wait patiently while it all happens. Your device will reboot automatically.. The first boot might take more than 5 minutes, so be patient until the device boots up. Done!

Note: To enable WiFi tethering on your S4 Active install the tether add-on zip file using Flash Fire app using the same method as above. Just make sure to use only Flash ZIP or OTA option and do not select the Wipe option this time.

  25. Big thank you for putting this walkthrough together. I’m now enjoying rooted Lollipop on my S4 with tethering enabled no less! I think I may just keep this phone for a bit more.

  26. I was stuck on the incorrect base version too. Created an XDA account just to thank you for taking the time to make this post. Worked beautifully.

  27. Pls can anyone help me, i was trying to install the rooted rom but my phone went black and refuse to boot. and the phone is no longer working

  28. I found out there is an authorized Samsung repair center (RSI) in Plano, TX. So I took my phone in there, showed them my receipt (it was still under warranty as I bought it new online), left it during lunch, and they had it updated to Lollipop when I returned. No problems! Don’t know why we couldn’t update it, but thanks for the info.

  29. I honestly don’t know. I shared pretty much exactly what I did, and that was flash AB, BL, CP, and CSC. Maybe you can try different version of Odin?

  30. I got stuck. Please help. I downloaded 4.4.2 NE3, full Odin package, and then unzipped. With Odin 3.9, I loaded the AP file, then booted the phone holding down arrow and home buttons and get it into “Downloading…” mode. My Win7 PC recognizes the phone, but when I click “Start” on Odin, and I get a “no PIT partition”. Can you provide any other details/steps of how you were successful? Maybe you did things in a different order?? I also tried Odin 3.10.6 with same result. Thanks!

  31. HI, i have a question, why odin ask for the pit file? where or how i can update my s4 to kitkat? im on jelly bean,but when i try update to kitkat send me a message ” Fail : Re-partition operation failed” what should i do?

  32. Hola, tengo este error,

  34. Hi trying to update from 4.4.2 to 5.0.1 OTA (NO ROOT) method, but keep getting this.(PICTURE).then the phone just boots back up and wipe all data,anyone knows how to fix this. tried root method also and no luck.

  35. Naww sorry and backup ur stuff because using odin to update to 4.4 will wipe all ur data, and as soon as you get 4.4 root it with towelroot don’t do anything else

  36. I was afraid of that. I’ll look into getting to 4.4 and see what I can do from there. Have any ideas?

  37. I’m following the directions to update and keep root. I follow the direction all the way and hit the lightning bolt to flash the phone. When it reboots, it shows the no command error, and i have options to reboot or attempt recovery

    I’m using 4.3 but the directions say it shouldnt be a problem

  38. After I hit the lightning bolt to flash, the phone reboots, but I get a No Command error and can only reboot from there. Any ideas? Need any more info?

  39. Wait this article is ABOUT getting 5.0.1 on the i537, with and without root, how can you say there hasnt been one yet?

  40. I want to know, did you tick every thing off just like the flashfire photo on the tutorial except we are using Flash Zip or OTA or did you do what they wrote on the tutorial and then add your part after.

  41. Mine kept doing that too but I kept trying

    Just flash the KitKat with odin from the first tutorial then enable USB debugging and root using towel root then use my method it should work

  42. Did your method to but still didn’t work phone boots up showing Samsung logo then the screen goes black and remain black, try flashing the software with odin but it’s failing. thank for your reply greatly appreciate it.

  43. Follow the root method on here, but before you are about to press the lightning bolt, press the “+” button and select everything except the internal storage.now u can press the lightning bolt to start

  44. Hi I have tried many of times and I would like to know what you did please, not sure ware I have to apply your method,

  53. Hi, I live in the British Virgin Island and I also have a SGH-I537 AT&T unlocked same baseband as Incognikool picture, I updated from 4.2.2 to 4.4.2 using the OTA method but lost my baseband, phone is saying baseband unknown. phone not recognizing sim card. need help please.

  54. so i did option number two and everything turned out great!!!! thank you so much! BUT when i installed the files for wifi tethering i forgot to uncheck wipe options i did not pay attention to that, my hotspot now works just like normal should i be worried?

  55. What u do is to first download the the 4.4.2 NE3 version and install using the OTA version but make sure u back up first cos u will definitely lose all your data, then follow the tutorial from that NE3 to NH3 part

  56. Hi, I have a Unlocked and rooted SGH-I537, I live in Venezuela so I cant use AT&T, it has Android Version 4.2.2, can I upgrade it to Lollipop keeping root w this tutorial?

  57. I have an unlocked AT&T Galaxy S4 Active (SGH-I537) that I am using on the t-moble network. Will the OTA Lollipop upgrade work with my phone on the tmobile network?

  58. Back up using kies on desktop then do the recovery and by the way it’s stock recovery and not custom

  59. You can use Odin to restore back to 4.4.2 incase u upgrade and u end up in soft brick, i.e the Samsung logo just comes on and then goes off

  60. Do u use the stock recovery or a custom one because I really don’t want wipe my data rakesh please help

  61. This is the best site ever, I finally got the lollipop after trying the flash fire and getting a soft brick. I went back to I537UCUCNE3 through Odin method and everything else upto the stage of lollipop works like magic. Thanks Rakesh

  62. Good afternoon , I could not even make the FlashFire root …… apk root access does not work I Could not be acquired , or you are not running Either SuperSU CMSU or are you rooted …. please suggest me I do

  63. this guide is amazing. everything works on my i537. I have to redownload a few files and try about three times, but it finally took with no errors.

  64. sorry for my bad english but i have a question, is possible to be in NH3 but the device still showing NE3?

  65. My S4 aCTIVE is in 4.4.2 (following the intructions above) but the Wi Fi it doesn´t work i cant turn on, and failed when try to update the Lollipo OTA package, please helpe me

  66. Hi, can you provide me with a different link where i can download NH3TOLOLIPOP, ive tried almost all the links some download have incorrect md5sum im exhausted trying to downlod the correct file. please help.

  67. so for the sake of the group, i did load all files into odin bl ap cs …. ect. but if failed about half way during the flash, so i tried loading only the ap file an it passed but as mention in the earlier post WiFi is not enabling due to security reasons. should i try kies or reflash using all the files??

  68. ygcgvgc no worries, jus restored my device to 4.4.2 kitkat after soft brick thanks to rakesh, the files wuked jus fine rakesh, thanks. one thing tho when i try enabling wi/fi a msg comes up saying[ my device security has blocked an action that is not permitted. no further action is required]. any ideas

  69. Im kinda scared of trying it because what is the phone breaks because there are alot of commets.u should make a video on how to do it

  70. I tried to do the version to keep root (had it rooted w/ towelroot and stuck on 4.2.2). I followed the instructions, but during the flashing process it got hung up forever. Eventually I forced it to restart, but ever since then it will only show the Samsung logo and restart. I tried to go into recovery mode and reset and wipe cache, still doesn’t work. I then tried to use odin to put the original firmware that was shared in another comment and it won’t allow me to go into download mode (I hold the required buttons, but it just powers off instead of goes into the download mode). So right now my phone is bricked, is there anything else I can do???

  71. tried that but the “Samsung Galaxy S4 active” welcome message pops up and goes off again. What do I do? I used the keep root method by the way

  72. Flashing the PIT with other firmware components is not necessary in all situations. You just go with the files I gave you earlier.

  73. Phone has been off for close to an hour after installation ..should I press the power button to turn it on normally or continue to wait ‘patiently’

  74. To go with the OTA method, you must have the NH3 base without root.
    If you want Lollipop+root through FlashFire method, you need to be rooted.

    As far as I know, the Lollipop bootloader is not downgradable. If you want to attempt downgrading to NH3, do it at your own responsibility.

  75. It won’t work for your if you have already taken the Lollipop update. There is no working root method available for the AT&T S4 Active on Lollipop.

  76. I don’t understand. Now that i’ve upgraded to Lollipop, how do i root it ? You say to download Flashfire and copy the file to the device but flashfire asks for a root. Or this walkthrough needed Android 4.2 ? It’s not really clear to me.

  77. After downloading the stock rooted version, must I move it to my SD CARD or just leave it in my phone memory before performing the flash fire process

  78. It’s because you have not joined the Google+ community for FireFlash with the same Gmail ID you use for Google Play. It loads for me.

  79. The thing there is that I flashed the stock ROM on my rooted I537 and I think that’s why I am getting the error. I will download the rooted one and flash it using the flash fire and I hope it won’t brick my phone

  80. We’re sorry, the requested URL was not found on this server.

    I could not that’s the phrase that appears

  81. Great Rakesh, i extracted the 4.4.2 firmware i linked me, but their are correlating tar files for each value in Odin, do i load each one or just the AP value? thanks

  82. Great Rakesh, i extracted the 4.4.2 firmware i linked me, but their are correlating tar files for each value in Odin, do i load each one or just the AP value? thanks

  83. I have decided to download the rooted one and also download flash fire but the link to the rooted lollipop expires once I pause and resume. Please fix it

  84. Friend I could not download the APK FlashFire … I am part of the community but do not see the download link you help me please

  87. hi i jus did the steps an now my phone turns on fr jus a second and powers off need help!!

  88. rooted my s4 active i537 {4.2.2 } using active root can i use this method mention to upgrade to lollipop

  89. If it does not work, you can roll back to an older version of stock firmware. As for problems after installing successfully, no one has reported any serious issue yet.

  90. What happens if my phone like doesn’t work after i do it and if it works what problems does it have does everything work,does it freeze alot,will it be slow

  91. just rename the “xxxxxx.cfg” to “updae.zip”. Copy update.zip to external sd card and install it via recovery 9see steps above).

  92. Yes, extract the ZIPs, rename the .cfg files as “update.zip” copy it to SD card and install it. When one is installed, do the same to others one by one.

  93. Ok thanks a lot for your time! Youve been a big help! And i have to extract all the files first before copying them to my sd card right?

  94. Ok sounds good! So all the updates i have to make, i download them and copy them to my sd card and then i install them from recovery mode? and i wont lose my data?

  95. Ok thanks a lot! When i install the NH3 update< if i would check if there is an update in settings? could i get it over the air to?

  96. Okay thanks! The OTA update above, is it the same as the official update givin by samsung or is it more lika a custom rom? i would like the lollipop update but i havent gotten it yet!

  97. Does anyone know if i can install the nh3 to lollipop even though my firmware is I537UCUCNC9? Its Android 4.4.2

  98. Yes. However, different people say different things about OTAs. Some say it installed on rooted phone and some say it failed to install as it detected root.

  99. Anyone know how to fix a problem that does not turn on wifi in 5.0.1 , 4.4.2 also happens to me , but no air 4.3

  100. I posted it^^ not turning on still after factory reset and wiping cahce partitions

  101. ok, please answer my last questions, also I did the factory reset, same problem. Just turns off. I don’t there is an operating system in the phone. Anyway of just putting lollipop in it now?

  102. ok, and what do I do after that to ugrade to lollipop. is it possible that I can do the “update from external storage” to get lollipop. Maybe put the lollipop rom on the SD card then do apdate from external storage? will that work? what are my option? please let me know thank you very much

  103. HI! PLease help!! I rooted my sgh1537 long time ago and it is also unlocked. I followed the steps for installing lollipop and keeping root carefully. I dont understand where I went wrong, I did all the procedures care fully, but now when I turn on my phone, all that shows up is the “Samsung galaxy S4 Active” logo! after that it just shuts off or something, idk, the screen jusat goes blank, no signs of life. What do I do?!?!? PLEASE let me know asap!!

  104. Successfully booted up quickly and still rooted! Everything got wiped, but I backed up my apps and contacts before so I’m not worried about that. Thank you very much for this tutorial! So glad to finally have Lollipop on my phone, been loving it on my Nexus 7.

  105. It’s showing up now. I installed it and it seems to be working. I’ll be proceeding with the instructions…

  106. I doubled checked that and I definitely am. Google Play said it may take a few hours for the beta build to become available, so I guess I’ll wait and see if it shows up in a bit.

  107. It doesn’t seem to be showing up in Google Play on my phone or on my computer. I downloaded it from the link in the instructions. I have signed up for the community.

  108. If I use the keep root option using FlashFire, will it keep all of my phone’s application data? Even the built-in apps like contacts? Thank you for the tutorial btw, I’ll be trying it as soon as Titanium Backup finishes.

  109. when i went to recovery mode i selected the file from my sdcard nd all it did was reset

  110. I have been waiting for the I537_OC6_Stock_Rooted_ROM to download for over a day. Could someone please upload it somewhere else?

  111. Some password error and somehow I got the cfg file and can’t rename it it’s not giving me the option to remove .cfg from the end.

  112. I’m getting an error when trying to extract the nh3tololipop and can’t rename the cfg file to update zip. Why?

  113. i can’t get officially it when i flashed back to stock it lose th imei number, tried different ways to restore the imei number and fails and i have it with the old mf1 modem.bin and the lollipop rooted rom but the the baseband fm1, if i flash the partitions of lollipop again i lose the imei. I don’t know what else i can do, i was almost 4 days trying to have the nh3 baseband but no luck

  114. so where can i get the flashfire apk to download from cant get it from play store since there is no app like that

  115. I made already 2 times and does not work , I also returned to version 4.4.2 and again perform the same procedure and the wifi still does not start , which tried Unsubscribe Stack as some say , but really not Turn on wifi

  116. Yes.. I have Root access and I am able to run rooted apps and root checker without problems.. I updated SuperSU (even re-installed it – same affect – The phone goes to recovery mode and does nothing)

    Here are the details of my device:

    SuperSU Free – V2.46
    FlashFire Free – v0.16
    Baseband – I537UCUBML2 (Jelly Bean 4.3)
    Build – JSS15JI537UCUBML2

  117. Can’t say it works. I have a rooted SGH-I537 running lots of root apps. Followd the steps EXACTLY as above.. Flashfire puts the phone into stock recovery mode without flashing everytime..

  118. He followed the process and am lollipop, but the wifi does not light, how do I fix .

  119. He followed the process and am lollipop, but the wifi does not light, how do I fix .

  120. Make sure that the update is not zipped twice. For whatever reason when I first downloaded it and tried it I kept getting signature failure and finally decided to crack the zip open to see what was in it only to find 2400258.cfg inside the zip. I copied it out and renamed that to update.zip and opened it to check the contents which were then correct. Flashed perfectly fine after that. Not sure why It appeared zipped twice but it works.

  121. I tried replying a couple times, not sure why that is not showing up. I was able to make this work by following Rakesh’s instructions about renaming the CFG file, and then following the revised instructions above. It went smoothly so I don’t have anything else I can tell you … (BTW, I doubt it matters but I think I got my zip file download from the CA source)

  122. I dont think he’s going to respond now. Could my problem be due to the IMEI being lost? If so..how can I regain my IMEI?

  123. Glad to know! Actually, I don’t have this phone so did not try the files. When you reported the error, just figured the probable cause.

  124. follow our posts or go back and re-read the instructions. The instructions were updated and now it works for me as well. I was having the same problem.

  125. Okay, now do this: rename “2400258.cfg” to “update.zip”. Then copy it to your device and install it. Let me know. It should work.

  126. No, it was running NE3. I was too tired to realize that last night as I was staying up to try and finish it at 5 am. But, it still says verification failed when trying to flash to NH3 from NE3.

  127. The no root option did not work for me. I confirmed I had the 4.4.2 NH3 version to start with. Went through the process and it basically just did a hard reset to my phone. I had to spend a bunch of time setting my phone back up. About Device says I’m still at 4.4.2. Tried checking for software updates manually and it is telling me none are available & try again after 24 hours. Any suggestions?

  128. Since the OTA package says “NH3 to Lollipop”, it means you need to have NH3 firmware installed on your S4 Active, You won’t be able to install unless you have the base NH3 firmware.

    “To be able to install the Android 5.0 Lollipop OTA package on your AT&T Galaxy S4 Active, your device must be fully stock (no root) with Android 4.4.2 (NH3) firmwarerunning on it. You can check your firmware and build version under Settings> About on your device. If your S4 Active is on a lower firmware version, download the NH3 firmware from below and install it. Then flash the NH3 OTA package using the instructions given below. You can then install the Lollipop OTA.”

  129. How do you do this exactly? I downloaded the OTA “NH3toLollipop.zip”, copied it to my SD card, rebooted into my recovery, selected install from external, selected the update.zip. After have watched it fail over 20 times with signature failures out the wazzoo, it just all of a sudden restarts, back to 4.4.2. Yes, I have the stock firmware installed. Yes, my device is the S4 Active SGH-i537 as well. It just doesnt work. If i could get help for this, please…I need the help.

  130. Even after flashing the stock images in Odin the OTA is failing signature verification. Any suggestions?
