Head over to the development thread to learn more about AOSP NeatROM.

Galaxy S3 users who wish to update their devices to Android 4.4.2 with AOSP NeatROM v2.4.1 may follow our step-by-step guide.

IBTimes UK reminds its readers that it will not be held responsible for any mishap. Before following the installation, users are also advised to ensure their devices meet following requirements.


1) Install USB Drivers for Galaxy S3 to transfer files between the Android device and the computer.

2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Navigate to Settings>> About phone. Tap on Build Number several times until a message appears saying 'You are now a Developer.' Now enable USB Debugging Mode by navigating to Settings>> Developer Options.]

3) As the tutorial might wipe out all data of the phone, create backup. If the device is having any custom recovery such as ClockworkMod or, TWRP then backup data using the same.

4) If the Android phone powers off due to lack of battery during the process, it could damage the device. Therefore, the Galaxy S3 should have charge above 80% battery charge.

5) The phone should be rooted and have ClockworkMod recovery installed. Ensure that latest version of recovery is installed. [The NeatROM can be installed using TWRP recovery as well. However, this guide uses CWM mode.]

6) The Android 4.4.2 KitKat AOSP NeatROM works only with Samsung Galaxy S3 GT-I9300. As applying this to any incorrect variant might brick the device, verify the model number of Galaxy S3 by navigating to Settings>> About device>> Model number.

7) After flashing the ROM if the device gets stuck on Booting animation or experiences boot loop, then perform wipe cache partition and wipe dalvik cache a few times before rebooting the device.
