AOKP Android 4.4.2 Nightlies will remove all bloatware from your Galaxy S4 and install a more pure KitKat OS on your phone, so that you will get the best out of it in terms of performance and functionality.

Read the guidelines below before starting the updating process:

  • use this post only with the T-Mobile version of Samsung Galaxy S4.
    – do not attempt to update any other Android devices with the files that you will find in this post.
  • your device has to be rooted and running the latest CWM Recovery image.
    – TWRP should also work with your phone, but we didn’t manage to test it.
    > note that whichever custom Recovery you have installed on your device, then you will make sure to update it to its latest version before starting the AOKP KitKat installation.
  • a NANDROID Backup for the installed ROM and a Factory Reset are required.
    – these steps are listed in the tutorial and you should not skip them.
    > Factory Reset will wipe all data from your phone’s system partition, while the internal and external storage will be left unaffected.
  • backup data from installed apps using Helium for Android — here.
  • sync Contacts data and People details with your default Gmail account you’ve set for your device.
  • enable USB Debugging from Developer Options menu.
  • charge the phone’s battery, so that the power level is over 50% – it will prevent the TMO Galaxy S4 from switching off during the installation of AOKP Android 4.4.2 ROM.
  • this is a guide for advanced Android users, do not blame us in case you lose any data or get your phone bricked in the process.
