Galaxy S3 users who wish to install Android 4.2.2 on their devices using SlimBean Build 5 may follow our step-by-step guide. The device may encounter minor bug issues with the installation since Build 5 is still in its development stage.

IBTimes UK reminds its readers that it will not be held liable for any damage to the device. Users are also advised to ensure their handsets meet following requirements.

Pre-requisites

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

5) The phone should be rooted and have ClockworkMod recovery installed.   

6) This SlimBean Build 5 ROM works only on Samsung Galaxy S3 I9300. As flashing this on any incorrect variant is likely to brick the device, verify the model number of Galaxy S3 by navigating to Settings>> About Phone.
