iphone 3gs ios 6 upgrade failure
I tried to upgrade my iPhone 3gs to ios 6 and it did not complete normatlly. The error message was "The iphone "iphone" could not be restored. An unknown error occurred (3014)". I researched solutions for this problem and did restores, DFU restore but no matter what I do, when I actually go to RESTORE from iTunes, I get the same 3014 error message shown above. So, I am stuck and the iPhone will not boot up.
I changed the USB cable with another one, I also downloaded the latest iTunes on another PC, and freshly downloaded ios 6 and retried on another PC but I get the same 3014 error message when trying to restore.
I disabled the firewall on the PCs, etc. as well but same error.
I have not done any jailbreaking or anything like that. Only periodic updates of iTunes and the ios.
Any ideas on how to bring my iPhone back up? I don't mind going back to the previous ios; I just want an operational iPhone.
Thank you very much for your help.
iPhone 3GS
