IBTimes UK reminds its readers that it will not be held responsible for any mishap. Before proceeding users are advised to ensure that their devices meet the requirements below.
1) Install USB Driver for Samsung Galaxy S2 on the computer.
2) Enable USB Debugging Mode to connect the phone 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) Create a backup of all the data of the device.
4) The Galaxy S2 should be rooted and have ClockworkMod (CWM) recovery installed.
5) Verify that the phone should have above 80 per cent of charge.
6) If the device is stuck on boot or experiencing boot loop, then perform 'wipe cache partition' and wipe dalvik cache' for a few more times before rebooting the device.
7) Navigate to Settings>> About Phone to verify the build number of the device since the AOKP Build 6 ROM is compatible only with Samsung Galaxy S2 I9100G. Installing this build on incorrect variant will brick the device.

6) In CWM recovery, perform a Nandroid backup of the existing ROM which can be restored later if the new one does not work or in case users wish to return to the previous build. To perform a backup select 'Backup and Restore' then on the next screen select 'Backup' again. Go back to the main recovery menu after backup is completed

9) After the ROM is installed, follow the similar procedure to install Google Apps zip
10) When the installation process is completed, go back to the main recovery menu and select 'reboot System now' to reboot the phone and boot up into the customised AOKP Jelly Bean ROM. The first boot will take some time.

[Note: In order to go back to the previous ROM, boot the device into recovery, then select 'backup and restore' then restore the previous ROM by selecting it from the list.]
