can someone please help me!! i installed CM10 on my galaxy s3 but i didnt get any service. i then reinstalled ics from the backup i made.﻿ But when i went back to the bootloader to try the cm10 again the screen shut off (just like normal) but it never came back on. the phone is completely unresponsive to anything. when i plug into my computer its not recognized either. the phone is literally a paper weight now any advice??
