My daughter abused the heck out of her iPhone. The screen in cracked beyond hope and it only works when plugged in to an electrical outlet. I had to replace it, but I'd like to get whatever I can out of the old one. I don't want to sell it for parts until it can be restored because it's full of photos and stuff. As I said, it will turn on when plugged in to a wall outlet, but if I connect it via USB to my computer, it won't do anything, not even power on. Any suggestions?
If the phone is broken and you have everything backed up, then why dont you get a new phone instead of restoring it?
Insetad of using computer to restore, you have another way to restore, just go to settings-> general-> reset-> erase all content and settings. This will do almost the same job.
