Help phone diconnects when trying to restore.
So earlier today I was just on my phone when I press the home button then sleep. A few seconds later I attempted to wake the phone trying both the home and sleep/wake button. No luck. Plugged the phone in to the power (not pc) after a few minutes the apple logo appeared but that was there for about an hour so i unplugged the phone. As soon as i did so the screen went blank again. I then plug it into my PC and put it in recovery mode as i have a backup not long ago and attemp to restore. New software is download first and is absolouly fine then my usb "unplug" sound goes off and it says "waiting for phone" before it says failed to resore (21) or something like that. Anybody got any idea?
