Install Android 4.0.3 rooted on your Samsung Galaxy S II i9100
There's no telling when Samsung will release the ICS update for Galaxy S II but if you're the impatient lot, then follow the steps below to get Ice Cream Sandwich update on your Galaxy S II.
The ROM(rooted) is Android 4.0.3 with build I9100XXLPB. Compared to prior releases, this build offers improved performance, stability and battery life. Please note that this is NOT an official release and therefore should not be compared to any update that might come from Samsung directly in the near future.
You need a rooted phone for this to work.
