I bought an iPhone 4S from the marketplace here, it had a damaged screen. I took it completely apart and replaced the screen, and that all worked fine. The software was all working fine as well, I was able to use the phone, no problem. I decided to do a fresh restore of the whole phone, thinking it would be no problem. So, I went to restore it, it extracted the data, and started putting the software back into the phone. It seems to get 3/4 of the way (judging by the bar on the iphone) and then give me an Error. "Your iPhone cannot be restored, an unknown error as occured. (Error -1)" Going off of iTunes, it seems as though it gets the software on there, and then errors while trying to install the Firmware. It was working before I tried to restore it, so not sure what could be happening here.. Is there anything else I can do? Is there another way to put software onto an iPhone other than through iTunes? I put it into recovery mode and that's what iTunes is picking up. I'm out of ideas here. P.S: It's a Verizon model if that makes any difference.
