Hi. I had ice cream sandwch android on my samsung galaxy s2 gi9100. So I downloaded an official crakd jelly bean for s2 from ibitimes.com . Many days it ran smoothly. But now its getting stuck.. also my memory reduced from 16gb to 12gb.
Please send me the link of any website where I can get a stable official updatable android os. Even if it is 4.0.4 , no problem. But I need a stable one which never crashs.. need ur expertise..plsss help me....
