Unlock SIM on Galaxy S3 and Note 2

It’s true that most users do some research before buying a smartphone and when it comes to choosing a carrier, they often make their decision after comparing plans and offers. In many cases users later find out that they made a mistake by going for a certain cellular operator because its offers poor service or an unstable connection. In a case where a device is locked to a carrier, a user might feel imprisoned.

In order to be able to switch to some other network provider, the user has to purchase hefty amount to get the SIM unlock code from the operator. In some cases, the carriers do not provide the unlock code until the contract period is over. Believe me, it really feels like hell to be left on the mercy of you network provider. There might be yet another reason why people want to unlock SIM on their device. Suppose you are planning to travel outside your country, you’ll certainly not be able to use a local SIM with your phone because it is network locked.

Of course, there are some websites that sell SIM unlock codes to those who are willing to pay a certain amount of money. But if you can unlock your device for free, there is no wisdom in wasting your hard-earned money. In the past, we covered various tutorials on unlocking Android device. Today, we’ll see how you can easily unlock SIM on Galaxy S3 and Note 2. The method described below works on the T-Mobile and Canadian Galaxy S3 and Galaxy Note 2. It have been tested successfully on following devices:

  • T-Mobile S3
  • T-Mobile Note 2
  • Rogers Note 2
  • Bell Galaxy Note 2
  • Bell Galaxy Rugby LTE
  • Telus Galaxy Note 2
  • Wind Mobile Note 2
  • Mobilicity Note 2
  • Wind Mobile S3
  • Mobilicity S3 YMMV
  • Bell Galaxy S3
  • Koodo Galaxy S3
  • Telus Galaxy S3
  • Rogers Galaxy S3

The SIM-unlocking method given below utilizes the unlock feature found on your phone’s system software and so it does not require root access. Needless to mention, the trick works only on Samsung’s TouchWiz-based stock ROMs.


If the procedure described below doesn’t work for you, you might need to downgrade your Galaxy S3/Note 2 to a lower version of firmware. The method has been tested on Android 4.1.1 and 4.1.2.

Unlock SIM on Galaxy S3 and Note 2

  1. Open your phone’s dialer.
  2. Dial the following keys *#197328640#
  3. Doing this will bring up the Service Menu of your device.
  4. Select [1] UMTS sim-unlock-menu-1
  5. Then tap [1] Debug Screen 
  6. Select [8] Phone Control on the next screen.
  7. Next, tap [6] Network Lock  option.
  8. Then select [3]Perso SHA256 OFF sim-unlock-menu-2
  9. Now wait for about 30 seconds and then go back one step by tapping the Menu button on your device and selecting Back option on the screen.

  11. This time select [4] NW Lock NV Data INITIALLIZ.

All of us love software updates as they bring new features, bug fixes and improvements in performance. Our device manufacturers keep sending new updates to give us a greater user experience.

  2. Look for a file named “install.bat” inside the Saferoot folder and double-click it.
  3. A new cmd window will open.
  4. Now connect your Verizon Note 2 to computer. Wait for a few moments till your device is connected successfully.
  5. Finally, press any key on your computer’s keyboard to trigger the rooting script.vzw-note-2-saferoot

A few days ago we broke out the news that Samsung have postponed the Android 4.3 Jelly Bean update for the Galaxy Note because they were not able to resolve some performance and stability related issue. It has been more than a month since we saw the first leaked firmware for this popular phablet device with build version N7100XXUEM16. At a time when the new update should have reached to the users long ago, there is still no news from the manufacturer as to when it plans to release the update.

What the users have been getting instead are some randomly leaked versions of Android 4.3 firmware now and then. In a very recent development regarding the new update Sammobile has shared another leaked firmware with build version N7100DDEMJ9. If you compare the older and new build numbers, you’ll notice a difference and it shows that the present version has been extensively revised. However, we cannot say with certainty how better in performance it is. We have some some feedback from the users who have tested the leaked test firmware and to believe them, it is more stable than the last release.

We would like to tell our users that the new  firmware is the unofficial version of the official one and flashing it on your Note 2 will not affect it warranty or trip the custom flash binary at all. The available firmware bears INU as CSC that means it is for India. Since it is an unbranded version, it can be installed on any Samsung Galaxy Note 2 GT-N7100 that is not locked to a network operator.

New Features and Changes:

  • New lockscreen with multi-page and widget support
  • New calculator
  • New video player, S Voice, Group Play, S Planner, Music Player, Gallery, Samsung Keyboard, Calculator
  • Some new icons
  • New music player with old icon
  • Display enhancement tweaks: text looks sharper and the screen more vivid
  • KNOX
  • New tabbed UI in Settings
  • Daydream
  • New Quick Settings page available in Notification panel
  • Galaxy S4 ringtones
  • ANT+ Support

android 4.4 kitkat rom on galaxy note 2

At a time when Nexus 5 users have been enjoying the new exclusive flavor of KitKat and other Nexus users are counting down the very hour when Android KitKat would reach their device, there is still a larger community of Android users who can only keep their fingers crossed in a hope that KitKat might come to them some day. Most of non-Nexus users have not  received even the lower versions of the OS like Android 4.2 and 4.3. Yesterday, we published a news that Samsung has pulled back the already out Android 4.3 update for the Galaxy S3 and postponed the OTA for Note 2 to fix some serious issues.

The users of both the Galaxy devices have been forced to remain with Android 4.1.2 and keeping in view Samsung’s software update policy for its older devices, it appears that it would take forever for Android 4.4 KitKat to come to these models. Thanks to the open source nature of Android that does not let some die of eating and others die of hunger. Yes, this is pretty true for those who have a rooted device with a custom recovery installed on it. I see it as an irony that we have lazy and careless OEMs whose only goal is to dump the market with new models, and then we have hard-working developers who keep trying to give us the latest and best of Android.

Anyway, if you own a Samsung Galaxy Note 2 and are frustrated with the jumbo delays in firmware update from Samsung and your carrier, it’s time to kick them to side and move on. You need not be jealous of Nexus users as the Android 4.4 KitKat based custom ROMs are now available for almost all the variants of Galaxy Note 2.

In the present article we’ll see some new ROMs that will let you enjoy the latest version of Android on your phablet device. Before proceeding, make sure you have one of the following variants of Note 2:

  • Samsung Galaxy Note 2 GT-N7100
  • Samsung Galaxy Note 2 LTE GT-N7105
  • AT&T Galaxy Note 2 SGH-I317
  • T-Mobile Galaxy Note 2 SGH-T889
  • Sprint Galaxy Note 2 SPH-L900
  • Verizon Galaxy Note 2 SCH-I605

You can check your phone’s model by going to Settings> About.


Please note that the procedure described below and considered risky and despite that fact that is has been tested successfully, you can get into trouble if you do not follow the steps to the word. We or the developers of the included ROMs shall not, in any case, be responsible for any mishap. Do not proceed unless you understand what you are going to do. Remember, you’ve been warned!


  • A rooted Galaxy Note 2
  • Latest version of CWM (v6.0.4.3 or above) or TWRP (vv2.6.3.0 or above) Recovery installed on the device. If you do not have the latest version of these recoveries, you’ll receive “Failed!” message while installing the ROM. The older versions do not have support for Android 4.4 KitKat. To update your recovery software, you can use the ROM Manager app (for CWM) or Goo Manager (for TWRP).


About the ROMs:

Please note that all the ROMs that are listed below are still in experimental stage. Therefore, do not expect bugless performance from them. I have tested the Omni ROM and the only issue I discovered was the camera FC bug. We hope that with new versions of the ROMs, all such bugs will be fixed.



Android 4.4 KitKat ROM on Galaxy Note 2:

Download Google Apps Package (for all):

Download the Latest SuperSU:

Download Camera App:

After installing the Android 4.4 based ROM in case you discover that  your app is not working, please download any of the photosphere camera apps from below and install it manually.

  3. Copy the downloaded Android 4.4 ROM file in zip (do not extract) to your Note 2.
  4. Then copy the Gapps file to the device.
  5. Now copy the “” file to the device too.
  6. Boot your Galaxy Note 2 into CWM/TWRP Recovery mode. To do this, hold down the Volume Up+Home+Power buttons together for 4-6 seconds till the screen turns up and you see the recovery screen. If you are not able to get into recovery using the key combo, use any of these apps.
  7. If you are using CWM, use the volume keys to scroll up/down and the power button to select files and options. TWRP users can simply touch the corresponding buttons to get a job done.
  8. Important: Before doing anything, do not forget to backup your current ROM using “backup and restore” option (in CWM) oe “Backup” option (in TWRP) and check all items to backup.
  9. CWM Users: Go back to main menu in recovery and select “wipe data / factory reset> yes”. Then go to “mounts and storage” and wipe data and system.
  10. TWRP Users: Just tap on “Wipe” button and select Data, System and Cache.
  11. Now go back again and choose “install zip from sdcard> choose zip from sd card” option, select the ROM file in zip and choose “yes” when asked. If you have TWRP, use “Install” button, select the ROM and swipe the slider to confirm installation.
  12. When the ROM is installed, install the Gapps zip package just like you flashed the ROM in Step 11.
  13. Then install the “” file the same way.
  14. Finally, select the reboot system option.
  15. Done!

The first boot will take a few minutes, so do not panic. Set up your data connection, Gmail, Google Wallet, etc. and enjoy the newly installed Android 4.4 based custom ROM. Enjoy and allow me to go on a KitKat Break too! Cheers!

We all know that Samsung cancelled the Android 4.2.2 update for a number of its devices like the Galaxy S3, Note 2 and Note 10.1 because it was late in rolling the update. The OEM then decided to upgrade the software version of these and some other devices directly to Android 4.3. The international GSM and LTE variants of the Galaxy S4 have already received the latest version of the OS and we already have the leaked 4.3 firmware for Note 2 GT-N7100 too.

When it comes to firmware update for the Galaxy devices, it seldom happens that a new version of firmware (leaked or official) arrives to a US carrier variant. XDA member designgears has shared Android 4.3 leaked firmwares for four devices from AT&T namely the Galaxy S3 SGH-I747, Note 2 SGH-I317, Galaxy S4 SGH-I337 and S4 Active SGH-I537. If you have any of these devices and you wish to get a peek into the latest version of Android before it’s available officially, you can download the complete firmware and install it manually using Odin or Heimdall.

Having installed to the leaked test firmware on your device, you’ll notice the following changes and features:

  • Galaxy Gear support
  • New Reading Mode in Display settings and Notification toggles
  • Driving Mode now becomes Hands-free Mode
  • Improvement in Camera performance and imaging
  • New tabbed UI in Settings
  • TouchWiz launcher now has less lag and feels much faster
  • Samsung Wallet comes pre-installed
  • Improved Keyboard

  • Samsung Browser is now fullscreen by default
  • New firmware adds Galaxy Gear support
  • OpenGL 3.0 Support
  • ANT+ Support
  • TRIM Support
  • Better RAM management
  • Many other UI tweaks to improve performance


Please note that the firmwares available below are test versions and therefore one should not expect perfection in performance. After installing the firmware on your Galaxy, you might discover bugs. The good thing, however, is that no user has yet reported any major bug. Installing this firmware will unroot your device and will wipe the apps and data. Therefore, we strongly recommend that you backup all important data before proceeding.  Also, install the firmware at your own risk. We do not hold any responsibility for any mishap.

Hidden-CSC-Features-on-Galaxy Samsung’s firmware for its Android devices have several components and CSC is one of them. The term is an abbreviated form of Consumer Software Customization and denotes to a specific geographical region or carrier branding. While most features of a specific Galaxy device are common globally, there are a bunch of other features that may or not be available to the end users in a particular country and region.

Every Android device from Samsung has a folder called csc under system directory. This folder contains some XML files that keep the configuration codes for country and carrier based customization options. If you have root access on your Samsung phone or tablet, you can access this directory and edit those XML file to enable or disable the features that are available or unavailable on your device. In other words, by editing the XML files present in the csc folder, you can easily personalize your device by adding features like your native language pack, screen rotation control, infinite scrolling on home screen, turn on/off camera shutter sound and so on.

        <!-- This is a comment. You may write anything between these tags -->
  4. Make sure to add your CSC feature comment line (you can find some of them below) between <FeatureSet> and </FeatureSet> otherwise it would not work.

Installing KNOX-Free Bootloader on Note 2:

When you are sure that you have made all required preparations and gathered the tools, follow the following steps to install the customized version of CWM recovery.

  1. Boot your Note 2 into Download Mode. To do this, press and hold the Volume Down, Home and Power buttons simultaneously for 2-3 seconds. When you see the warning screen, press the Volume Up key.
  2. Launch Odin and connect your device to PC via USB cable.

  6. Finally, you will get PASS!! message at Odin and your Note 2 will reboot automatically.

When your device boots up, KNOX will be disabled on it. However, disabling KNOX will create issue with WiFi connectivity on your Note 2. To fix it, you will have to install WiFi patch file using the same steps (as you did above) in Odin. But  this time you have to select patch.tar.md5 file (in PDA section) from the extracted wifi_fix_for_MJ2 folder.


Install PhilZ Touch Recovery on Note 2:

To root the Samsung Galaxy Note 2 GT-N7100 on Android 4.3, we’ll use the advanced multi tool utility by DR. Ketan.

  1. Boot it into Recovery Mode. To do this, press Volume Up, Home and Power keys at the same time for 4-6 seconds till you enter the CWM recovery main menu.
  2. Go to “install zip from sdcard” option, navigate to the file and select it.
  3. Select “yes” to confirm installation.
  4. You’ll then be taken to Aroma installer. Select root option in Aroma:note-2-multitool-root
  5. Besides rooting your Galaxy Note 2, MultiTool can also install a custom recovery, kernel, clean bloat apps and perform various useful tasks.
  6. Finally, select reboot system option in Aroma.

Your Galaxy Note 2 will boot now. When your device becomes ready to use, open app drawer an look for a new app named “SupeSU” there. If you can see this app, your device is rooted. To verify proper root access, install Root Checker app from the Play Store and run it.

The are various instances of exploits bringing out the security vulnerabilities of Samsung’s flagship Galaxy devices. To arouse the trust of business class customers, Samsung also launched an ad campaign. However, it was with the launch of the Galaxy S4 that the company introduced a dedicated security service trademarked as Samsung KNOX.

Previously, the service was only available for people in enterprise and in government institutions. Later during IFA event in Berlin, Samsung  showcased some new devices like the Note 3, Note 10.1 2014 Edition, Galaxy Gear and also revealed the commercial availability of a its Knox mobile security system that helps better protect device data against unauthorized use.


What is Samsung KNOX?

In this way, if you have Knox installed on your device which you use as a personal and as a workplace phone both, Knox lets you store enterprise applications (corporate email, contacts, calendar, etc.) securely using an Exchange ActiveSync Server. The service is capable of separating personal and work data and thus it makes it possible for both types of data to coexist on a Knox-enabled device. You just have to press an icon to switch from personal to business mode.

Here’s an official video that reveals what KNOX does:

Actually, Samsung came with KNOX when it realized that security-lovers and corporate class tended to  abstain from its smartphones due to security vulnerabilities. By integrating KNOX in the TouchWiz UX, Samsung provided a second version of a smartphone as KNOX mode that is protected with password and restricts unauthorized access. KNOX mode includes apps like Camera, Gallery, Downloads, Email, S Planner, My files, Phone, Contacts and S Browser by default. Besides these, there are about 75 KNOX-apps that you can download additionally.


Why Disable Samsung KNOX?

There’s no doubt that Samsung Knox service is really a good security solution for those who got a financial and business reason to protect their data, but there are still many others who might not like to have it on their device. If you are not a fan of the kind of security Knox provides and love to root your device and install custom ROMs on it without caring about the security warnings, we have come with some tips to disable Samsung Knox security shield on your device. Knox might also be responsible for FC (force close) error with some of your root perm apps, and so this is another sound reason to disable it.


Unable to Get Root Access Due to KNOX?

If you have KNOX on your Galaxy device and you have rooted it, you’ll see a verification message that pops up every time SuperSU is called for action by some apps on your device. The message runs like this:

“SuperSU tried to access system in your device without authorization. This action was blocked.”


“An application attempted to access system on your device without authorization.”


“Unauthorized access to a secured area has been blocked.”

You can get rid of this annoying thing easily by disabling Knox service and its agent apps. Remember, once KNOX is aware of SuperUser on your phone, it’ll block its functioning and you might not be able to use any root app. In case you are unable to get root access (after rooting your device) because KNOX prevents SuperSU in doing so, do this:

  1. Download the latest SuperSU zip package:
  2. Extract the zip and open the folder.disable knox security 2
  3. Go the folder named “common” and copy the Superuser.apk to your phone.
  4. Install the APK manually (do not forget to tick Unknown Sources option under Security settings of your device).
  5. Now launch the SuperSU app on your phone and it will ask you whether or not you want to disable KNOX: “Samsung Knox has been detected. This might limit root capabilities and cause annoying popups. Try to disable KNOX.”
  6. Select OK. It will then tell you that KNOX has been successfully disabled.disable-knox-security-2
