Folks at Sammobile have done it again. They have released two new leaked official Ice Cream Sandwich firmwares for Samsung Galaxy S II. According to early reports, being the early builds, they have fair share of bugs and can be slow at times. So, basically you can use them to test Android 4.0 on your S2 for some time and then get back to Gingerbread.
- I9100XXKP4 – Android 4.0.1 Build – December 20 2011
- I9100XXKP8 – Android 4.0.3 Build – December 30 2011 (better one)
These are flash-able via ODIN. So, all you have to do it grab the firmware files from Sammobile along with ODIN, backup your phone data and just flash one of the builds.
