Flash AOKP KitKat 4.4.2 Nightlies for US Cellular Galaxy S3

The new build of AOKP KitKat Nightlies is now ready for the US Cellular variant of Samsung Galaxy S3. Read this entire tutorial and you will manage to successfully flash the brand new ROM without bricking your device’s firmware.

This custom ROM is obviously based on AOSP Android 4.4.2, but it also features its own elements created by the AOKP Team along with other things borrowed from CyanogenMod and Paranoid Android. Learn more about this ROM at its website here. Read the guidelines below before getting to the tutorial:

  • this post works only with rooted US Cellular Samsung Galaxy S3.
    – do not attempt to install the custom ROM on any other Android device.
  • CWM or TWRP Recovery should be installed on your device.
    – in the tutorial you will find instructions for CWM Recovery, but you can TWRP, too. Make sure that you apply the corresponding options.
    – note that your installed custom Recovery has to be running the latest version, as otherwise you won’t be able to flash any type of Kitkat custom ROM.
  • do not skip any steps listed in the tutorial.
    – the Factory Reset step wipes only the system partition, while it leaves the internal and external sdcards unaffected.
  • read the entire tutorial first and do not blame us in case you brick your phone or lose any important data.
  • backup data from installed apps, SMS or other similar files with Helium for Android.
  • check the phone’s battery charge and make sure that it is over 50%, so that your phone will not switch off while you’re flashing the new ROM.
  • sync Contacts info with your default Gmail account.
    – if you can’t do it, then you can use the info in this post to learn.
  • if you cannot complete the guide, then you can ask for more help in comments.
