I just bought a new Galaxy S2 today. I did all the essentials and ran the update and it was running fine. I was simply waiting for the battery to finish its first charge. Then it simply turned off on me and every time I try to turn it back on it freezes at the black screen with the Samsung Galaxy S II. I already tried removing the battery and that didnt help. I tried turning it back off using the power button and it still didnt fix the problem. Any ideas on what I could do?
