SlimBean Build 4.2 custom firmware is also released for the international version of Samsung Galaxy S2 with model number I9100. 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.  

 Pre-requisites

1) Install USB Drivers for Samsung Galaxy S2 to transfer files between the Android device to the computer.

2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.]  

3) The tutorial might wipe all data of the phone, therefore, create backup for the same before proceeding. If the device is having custom recovery such as ClockworkMod/TWRP already installed then users are recommended to backup data using the same.

4) The Galaxy S2 should have above 80% of battery charge.

5) The phone should be rooted and have ClockworkMod recovery installed. Follow the guide here to root and install CWM recovery on Galaxy S2 I9100.

6) The SlimBean Build 4.2 ROM works only on Samsung Galaxy S2 I9100. Flashing this on any other variant is likely to brick the device. Therefore, verify the model number of Galaxy S2 by navigating to Settings>> About phone.  

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 five more times before rebooting the device.
