Hi guys , This is my situation I bought a iPhone 5 from the bay last week to replace my broken iPhone 4. The ad quoted a cracked screen but factory unlocked. So I changed my screen and put the simcard in and it worked fine for 2 days. The phone then ran out battery, once I charged it up the apple logo shows then it just reboots every 5 seconds. So it got me thinking had the phone been jailbreaked and unlocked, maybe? I really don't know as I couldn't play on it much but there certainly wasn't cydia installed! So now I'm stick with a phone which won't turn on and iTunes won't restore I get errors when trying iOS 7.0.4 or 7.0.6 and I either get error 4193 or 9 when restoring too iOS 7.1. I'd really like to get it fixed as I haven't had a phone for weeks now. By the way I have access to both PC and Mac. I hope you can help. Thank you.
