I have been working on this thing for about a solid day. this iphone would not turn on, so I took it apart and checked all the connections, reinstalled and to my surprise it turned on. It loaded up and everything worked accordingly, however I did buy this iphone off craigslist so I immediately went to settings to erase the content. I didn't check what version iOS and all that because I thought I could just set it back up. Well thats when all the problems occurred. I've done everything I know to get this thing through and it seems like everytime I try I get closer and closer. It started out with 16xx errors and 21, wouldnt even prepare the iphone for the restore. Ive done: disconnected logic board from battery updated my computer updated itunes switched computers switched usb ports tried in DFU mode held button while plugging into itunes it went from not even able to prepare, to being stuck a 1/4 of the way when restoring, to stopping 3/4 of the way and giving error code 14. I figure that its getting closer each time. This iphone was working just fine before I erased the data. Anyone have any suggestions? thanks!
