Flash Unofficial CM 11 Android 4.4 custom ROM for Sprint Samsung Galaxy Note 2

The Sprint variant of the Samsung Galaxy Note 2 device can now be updated to Android 4.4 using an unofficial build of CyanogenMod 11 custom ROM. Read this entire tutorial and learn how to successfully update your device. Make sure to read the entire tutorial and don’t skip any steps that I’ve listed below.

Unofficial CM 11 is based on Android 4.4 KitKat created by XDA member and developer, sbrissen. It is not an official release by CM team, so you should expect some bugs and errors, which is why you should only install it if you’re a user who want to tinker with his Galaxy Note 2 device.

Before starting the installation you need to take a look at the preparation guide below:

  • The article works only with Sprint variant of Samsung Galaxy Note 2 model number L900.
    – don’t attempt to update any other different Samsung Galaxy Note 2 models, as you will end up bricking their firmware.
  • The Sprint Note 2 you’re about to update has to be rooted, factory unlocked and running a CWM or TWRP Recovery Modes.
  • Factory Reset is required in the process. The step can be found in the tutorial guide.
    – this will remove all data from system partition.
    – factory reset doesn’t mess with your internal nor external storage cards.
  • In the how-to part of this post you’ll find the ‘backup and restore’ step. That will teach you how to create a full NANROID Backup of your currently installed ROM, which means that you shouldn’t skip it.
    – such full ROM Backup file will allow you to restore your device to its previous working state any time you want.
    – it can be used in case the new ROM doesn’t boot correctly or you find too many errors while testing it.
  • It is not recommended to use tools that are capable of restoring data from installed apps. But, you can at least try to use Helium from Google Play Store here.
  • Backup SMS text messages and APN Internet Settings using the following tools for Android: SMS backup & restore | APN Settings Backup & Restore. Root access will be required for these small tools.
  • People details and Contacts info can be synced with your Gmail account.
    – if you don’t know how to do it, then you can use the guide here.
  • Read the entire post, don’t skip any steps and do not blame us in case you brick your phone or lose any important data in the process.
  • Make sure that your phone’s battery has enough power left before it completely switches off.
  • If you cannot complete the tutorial, then you should ask for more help in comments.

Now that you’ve read all of the above, continue to the next part of this post and learn how to flash a KitKat custom ROM on your phablet. Also, for any extra info on this release, follow the XDA thread here.

How to flash Unofficial CM 11 Android 4.4 custom ROM for Sprint Samsung Galaxy Note 2:

  1. Download the Unofficial CyanogenMod 11 custom ROM zip from here.
  2. Download Gapps for this custom ROM here.
  3. Connect your smartphone with your computer, then move both zip files to your Note 2 internal storage.
    – after the files are copied successfully, disconnect the device from PC.
  4. Power off your phone completely.
  5. Boot it in custom Recovery Mode now.
    – note that you need to run the latest TWRP / CWM Recovery images, as otherwise you cannot flash the custom ROM zip file.
  6. First you need to create the full NANDROID Backup for the ROM that is currently installed on your device:
    – CWM: select ‘backup and restore’, then save the file. Confirm the process.
    – TWRP: press Backup, then rename the file. Swipe to apply the backup.
  7. Next, apply Factory Reset:
    – CWM: select ‘wipe data/ factory reset’ and confirm.
    – TWRP: press Wipe, then swipe the blue button to factory reset your phone.
  8. Now you can install the new custom ROM:
    – CWM: select ‘install zip from sdcard’, then ‘choose zip from sdcard’. Find the Unofficial CM11 zip and confirm its installation.
    – TWRP: press Install, then browse your phone’s internal storage for the Unofficial CM 11 zip file. Swipe to install the new ROM files.
  9. When the Unofficial CyanogenMod 11 KitKat ROM is flashed, repeat step 8 and flash the Gapps files too.
  10. After you do manage to complete the installation of both files, return to the main screen of CWM / TWRP Recovery.
  11. Reboot your phone now in normal mode.
    – note that the first boot process takes several minutes to complete, so you should wait.
  12. When the Unofficial CM11 KitKat home screen appears, enter your Google Account info and take control over your phone again.
  13. Start testing the new features and see if your device is running better than it did with its previous ROM.

NOTE: in case the new ROM doesn’t boot normally, the device enters into a boot loop or it doesn’t go past the Samsung boot animation screen, then you will be forced to remove its battery. Re-insert the battery back into your phone and then repeat the entire tutorial once again.

If you have any other problems with the installation, then you need to ask for more help in comments below.
