DORIMANX KERNEL for JB on the Samsung Galaxy S2... i9100, i9100M, i9100T & i9100P only and no other variant. (If you are unsure of the model of your phone, go to Settings > About phone > Model number) Supports SAMSUNG STOCK/ AOKP / JB-AOKP / CM9 / Jelly Bean + CM10 / Sense 4 All. Installation instructions (please read carefully and thoroughly) You will need to be rooted, see here, and have ClockWorkMod, (CWM), installed. Before doing anything, you should do a nandroid and Titanium backup. You should also install Root Explorer, or a similar file manager, and use it to navigate to the, "/efs", file in the root directory of the phone and make a copy of this and put it on both your external SD card and PC as its loss or corruption in future could render your phone unusable and require a Samsung repair. Alternatively, you can install, "GS2 Repair", free from the Play Store which can do this for you. These are your, "Get out of jail FREE" cards in case anything goes wrong, now or in the future. Download the .zip version of the Dorimanx kernel and Hawker's, GS2Wiper and place them on your external SD card, safest place, (if you downloaded them using your phone they will be in... "/sdcard/Download"), and then go into Recovery and select, "install zip from sdcard", followed by, "choose .zip from sdcard", and then navigate down the menu until you get to "GS2Wiper" and install it. It is a small script that wipes any crud from your previous kernel and takes about 2 seconds to complete. You then navigate to "Kernel_Dorimanx-V?", and install it and then reboot your phone.
