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

  • use this tutorial only with the International LTE Samsung Galaxy S4 model number I9505.
    – that’s the Snapdragon model, not the Exynos variant.
    – don’t update any other devices with the files that you will find in this post.
  • your Galaxy S4 has to be rooted and running the latest CWM or TWRP Recovery build.
    – if your installed custom Recovery isn’t updated to its latest version, then it cannot be used to flash a KitKat custom ROM.
  • the tutorial will tell you to create a NANDROID ROM Backup and apply a Factory Reset, don’t skip any of these steps.
    – NANDROID Backup creates a restore point for your phone, one that you can use in case the new ROM doesn’t boot correctly or in case you don’t like how it works with your phone.
    – Factory Reset will wipe the data from system partition, but it will allow you to clean install AOSB Android 4.4.2 KitKat ROM.
    – the Factory Reset process will not remove any data from internal nor external storage.
  • if you want to backup data from installed apps, SMS text messages or other data you should use Helium for Android.
  • Sync Contacts info and People details with your default Gmail account.
  • check the battery power level and make sure that it is over 50%, so that it won’t switch off in the middle of the installation process.
  • read the entire tutorial first, don’t skip any steps and you won’t have any problems flashing the custom Android 4.4.2 ROM.
  • note that this post should be used by advanced users, do not blame us nor the developers in case you brick your Galaxy S4 LTE.

Since you’ve read all of the above you can continue to the next step and learn how to successfully update your phone.

I hope that you managed to complete installation and that now you’re customizing all the ROMs features. In case the installation fails, then you can repeat the entire tutorial several times until the ROM manages to install. Such custom ROMs might not always install at the first attempt, which is why you have to repeat the guide from time to time.
