Use Official CM 10.2 Nightly ROM to Update T-Mobile Samsung Galaxy Note 2 to Android 4.3 Jelly Bean

Install CM 10.2 Nightly ROM for the Samsung Galaxy

Read this entire article and you will learn how to successfully update the Samsung Galaxy Note 2 T-Mobile variant with official CyanogenMod 10.2 Nightly ROM.

This new build is a testing one as are all Nightlies that are usually launched by CyanogenMod team. It is based on AOSP Android 4.3 and if you want to install it on your smartphone, then you should first read the guidelines below:

  • Use this post only with the T-Mobile variant of the Samsung Galaxy Note 2.
  • Don’t attempt to update any other devices using the info listed in this post, as you will brick them.
  • The ‘phablet’ has to be factory unlocked, rooted and running a custom Recovery image like CWM or TWRP.
  • The Factory Reset step will remove the contents from the system partition. This is required so that the new ROM will successfully install and boot into normal mode.
  • The contents stored on the Internal / External storage won’t be affected by this installation.
  • Backup installed applications data using Helium app from Google Play Store here, or use Titanium Backup tool here.
  • Backup SMS, Call Logs info and APN Internet Settings using the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access is needed for some of these apps.
  • Sync your Contacts with your Gmail account. This will backup to Google cloud all your saved phone numbers and other Contacts data that’s stored on your phone right now.
  • Create a NANDROID Backup of your currently installed ROM. This will set a restore point for your phone and it can be used in case something goes wrong.
  • Enable USB Debugging from Developers Options.
  • Make sure that your phone’s battery has enough power so that it won’t switch off in the middle of the updating process.
  • This is a guide for advanced users. You cannot blame us in case you brick the phone or you lose data after installing the new ROM.
  • If you cannot complete the update, then you should ask for more help in comments.

How to install CM 10.2 Nightly Android 4.3 Custom ROM for T-Mobile Samsung Galaxy Note 2:

  1. Download CM 10.2 Nightly latest build from here.
  2. Download Gapps for Android 4.3 custom ROMs from here.
  3. Connect your TMO Note 2 with your PC using USB cable.
  4. Move both zip files to your phone’s internal storage. Remember where you’ve copied the files as you will need to find them later.
  5. When the files are copied, disconnect the device from PC.
  6. Power off the phablet now.
  7. Boot the device into CWM or TWRP Recovery Mode. Both versions will work with this tutorial.
  8. First you need to create a NANDROID Backup of your currently installed ROM:
    – TWRP Recovery: press Backup, then select the system files you want to backup and confirm.
    – CWM Recovery: select ‘backup and restore’, then confirm.
  9. Now you have to apply ‘factory reset’ for a clean installation of CM 10.2 Nightly ROM:
    – TWRP Recovery: press Wipe, then Factory Reset. Confirm.
    – CWM Recovery: select ‘wipe data/ factory reset’. Confirm.
    > this step can be skipped in case your device already runs on a previous CM 10.2 Nightly build.
    > if the new ROM doesn’t boot then you need to return to this step and apply factory reset. For other problems use the comments section.
  10. Next, start the installation of the new CyanogenMod 10.2 Nightly ROM for your T Mobile Galaxy Note 2:
    – TWRP Recovery: press Install. Find the CM 10.2 Nightly zip and use the blue button at the bottom of the screen to start the installation.
    – CWM Recovery: select ‘install zip from sdcard’, then ‘choose zip from sdcard’. Find the CM 10.2 Nightly zip and confirm that you want to install it.
  11. After the CyanogenMod 10.2 is successfully flashed on your Galaxy Note 2 TMO you need to repeat step 10. This time you have to flash the Gapps zip.
  12. When the installation of both zip files is complete, return to the main CWM / TWRP Recovery screen.
  13. Reboot your smartphone.

Now wait for your phone to boot into normal mode and note that the first boot process of CM 10.2 Nightly might take a while before it manages to load all the required files. In case the device doesn’t boot correctly or it enters into a boot loop, then you should power it off and repeat the entire tutorial starting with step 6. Make sure that you don’t skip any steps.

If you don’t like the performance of your Galaxy Note 2 T-Mobile when it runs with CM 10.2 Nightly, then you can use the NANDROID Backup files created in step 8 in order to restore it to its previous ROM. For any other problems you should use the comments section.
