iPhone stuck in restoring
Tried to update phone's OS from 8.2.3(or something) to 10.2.3 only to have it stuck with the apple logo and the progress bar. As it reaches about 70 percent of the bar, it stops moving forward and eventually restarts.
I put it into DFU mode, tried updating with another computer and eventually it worked. Unfortunately, I'm now trying to revert back to the backup I had saved of the prior OS only to be stuck with the same problem with the progress bar and the apple logo as it reboots endlessly as the bar reaches about 70% and stops.
Am glad to provide any other helpful info.
