Galaxy S2 users who wish to install Android 4.2.2 using the SlimBean Build 4.2, may follow our step-by-step guide. The device may encounter with minor bug issues after flashing the Build 4.2 as it is in its development stage.

It should be noted that those users who are on Build 4 should be able to dirty flash the Build 4.2. But those who are running on older version should perform data wipe.

IBTimes UK reminds its readers that it will not be held liable for any mishap. Users are also advised to ensure that their devices meet following requirements before installing the custom build.
