I managed to successfully flash iOS 6 onto an iPhone 4s and it worked fine. I then had to put the back cover on and put a few covers back and when I was doing that, I accidently shorted the battery positive to the case. It was only for a fraction of a second and judging by the location, shouldn't have harmed anything. Even so the battery is pretty much dead anyway. Now onto the strange stuff. When I tried to power it on after this, it was stuck in a short bootloop and wouldn't turn on. I have tried both iTunes and 3uTools to recover the phone but I get error 21 with itunes and error -2 on 3uTools. Any suggestions much appreciated!
