Interested users, who wish to update Galaxy S3 to Android 4.4.2 using Fusion Boeffla ROM, may follow our step-by-step guide.

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

Pre-requisites

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 has any custom recovery such as ClockworkMod or, TWRP then back up 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 above 80% battery charge.

5) The phone should be rooted and have the latest version of ClockworkMod recovery. [Click here for our guide to root Galaxy S3.]

6) Android 4.4.2 KitKat Fusion Boeffla ROM 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 phone>> Model number.

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

8) Once the ROM is installed, users are advised to give 10 minutes to the ROM after the device boots up for the first time for better user experience.
