Read these guidelines before starting the installation process:
- use this tutorial only with the Samsung Galaxy S3 model number I9300 – the Exynos CPU model.

- your phone has to be rooted and running the latest build of either CWM or TWRP Recovery..
– note that in case your device doesn’t have the latest custom Recovery version installed on it, then you cannot flash any new KitKat custom ROMs.
- the tutorial will tell you to Factory Reset the phone and create a NANDROID Backup for the installed OS before applying Factory Reset. Do not skip those steps.
– NANDROID ROM Backup sets a restore point for your phone, one that can be used in case your device doesn’t boot in normal mode.
– Factory Reset allows you to apply a clean installation of AOSB Android 4.4.2 for your Galaxy S3.
– Factory Reset wipes data from system partition, while it leaves the internal and external storage unaffected.
- save data from installed apps, SMS and other similar files using the Helium tool for Android.

- read the entire post, don’t skip any steps and you should be able to complete the tutorial easily without bricking your phone.
- check the battery charge level of your device and make sure that it is over 50%, so that your phone will not switch off in the middle of the installation.
- this guide is for advanced users, do not blame us nor the developers in case you brick the phone.
