This is my fist post so keep with me. I recently rooted my sgs2 i1900 (unlocked from 3 network) with no problems and them flashed slim rom 4.2.2 again with no problem. I have been using it for a few weeks with no problem and then yesterday it has got stuck on boot up. The only way to turn the phone off is to remove the battery. My question is how do I repair this problem? Is it a full install all over again? Any help would be appreciated. Sorry in advance if typist is in the wrong place.
