Hey everyone, first post. My dad gave me his old iPhone 5s for me to try to fix, seeing as I can't afford to get a new phone. He told me that he was using it like normal, and then it went to a blue screen, followed be a reboot loop. He eventually got it to show a "Connect to iTunes" screen, then tried to restore it, but it didn't work. Disconnected halfway through or something, maybe a flaky cable. When I connect it to my computer, it shows the apple logo for maybe half a second, then goes to the connect to iTunes screen. I've managed to get it into DFU mode, iTunes recognizes it as a phone in recovery mode, and I'm downloading iOS 10.0.2 in the hopes that installing it will fix the phone. Should this work? Is there a way I can guarantee that it's not a hardware problem? I read on another thread that if I'm able to get it into recovery mode and get iTunes to mount it, it's definitely a software issue, but I'm hoping someone else can confirm that for my situation. Would love to get this thing working, I hope I'll be able to get some help here.
