So, my S3 started to freeze randomly so I would take the battery out and reboot it until it wouldn't boot past the initial s3 GT-I9300 screen (not the blue samsung splash screen) I tried to go into recovery mode, but it would go back to the screen. after a couple of times of me taking the battery out and rebooting, it asked me to do a factory reset...me being the ***** I am, I once again took the battery out etc...so I tried to do a firmware upgrade and initialization, but samsung kies does not detect my device ( my computer doesnt detect my device either, but it still installs the drivers and it doesnt charge) so can anybody PLEASE help me out? Or has my phone been destroyed?
