Update AT&T Samsung Galaxy Note 2 to Android 4.4 using OmniROM KitKat Nightlies

The official OmniROM Android 4.4 Nightlies are now available for the AT&T Samsung Galaxy Note 2 device. Learn how to install it using the info that I’ve listed in this post.

OmniROM KitKat Nightly is in its first phase and now it might not be the most stable ROM but it will do its work, which is to allow as many users as possible to test the latest Android 4.4 features. Besides the AOSP Android features you will also be getting some OmniROM new elements: the multi-window support, multi-workspace, per-app permissions controls, flippable quick settings menu, a new more minimal incoming call alert and others more.

Before starting the installation you will first have to take a look at the guidelines below:

  • Use this post only with the AT&T variant of the Galaxy Note 2 phone.
    – do not attempt to update any other devices with the files that you find in this article.
  • Your phablet device has to be rooted and running the latest CWM Recovery image.
  • Factory Reset is required and you shouldn’t skip it, as this step is found in the tutorial.
    – note that the Factory Reset process will wipe data from the system part of your device, while the internal and external storage won’t be affected by this process.
  • Backup data from installed applications using Helium tool here ( Google Play Store link).
  • 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 needed for these tools.
  • Sync Contacts data and other People details with your default Gmail account.
    – if you don’t know how to do it, then you can follow the info listed here.
  • Enable USB Debugging from Developer Options section.
  • Check your phone’s battery power level and make sure that it is over 50%, so that you won’t see the phone switching off before the installation is complete.
  • NANDROID ROM Backup is required for the OS that is currently running on your smartphone.
    – this will create a restore point for your phone and you can use it in case the new OmniROM KitKat Nightly doesn’t boot correctly in normal mode.
  • This is a tutorial for advanced users and you shouldn’t blame us in case you brick the phone or lose any important data in the process.
    – read the entire post and make sure not to skip any steps in order to complete the installation.
  • For any extra help use the comments field.

These were all the guidelines that you had to go over in order to correctly configure your smartphone for the installation of a new custom ROM.
