iOS 6.1 - [HELP] iPhone 4 will not turn on.
I'm in need of some help! I recently upgraded a friends iPhone 4 from iOS 4.2 to 6.1.3 and attempted to jailbreak it through redsn0w. I received an error and was getting constant apple logo reboots. I was a able to enter DFU a few times and I still received errors when attempting to jailbreak it.
Now the device has turn off but I can't get it to boot back up, I have tried to hard reset probably 30 times and I have tried enter DFU and Recovery mode with no success, the device this wont boot (black screen).
I really hope that I didn't accidentally brick the device by trying to jailbreak it. Is there any other way that I can get the device to boot up? Some other button combo? I cant get it to recognize in windows either...
If anyone has any knowledge they could provide I would really appreciate it!
