ios 6 upgrade problems

My iPhone 4S is not unlocked nor jailbreaked yet when I connected it to my PC the installation failed and my phone has been wiped. I have tried many times since to restore it but keep getting a message to say, 'The iPhone could not be restored, an unknown error occurred.' Very annoying. I haven't yet found a solution to it either so have no phone. I have had two different error messages one is 3014 and the other -1.

iPhone 4S, iOS 6

I'm having the exact same problem.

when I connected it to my PC the installation failed and my phone has been wiped. I have tried many times since to restore it but keep getting a message to say, 'The iPhone could not be restored, an unknown error occurred.'



so i keep trying, and it keeps stalling on "preparing iPhone for restore"... then after a while it times out, I get the "The Iphone coule not be restored, an unknown error occured message." only difference is, my error number is 1604. So I restart my phone and try again, and the same thing keeps happening over and over. On my 7th try now. Really frustrating

Update: Maybe it's an issue of updating iTunes and iPhone one right after the other?


I updated my iTunes. It prompted me to restart my computer, but I didn't do it straight away. Then I went to try and update my iphone. And that's when I had the issue above.


It just occured to me that maybe it's cos the iTunes update wasn't completely finished?

So I restarted my computer, restarted iTunes, accepted the licence agreement for the new version of itunes, and THEN tried to update my phone again. and it worked. in like 2 minutes flat.


If you're having this trouble, have you just updated iTunes too? Have you restarted your machine since? Try restarting your computer and then see if that helps.


wish I didn't have to lose all the data off my phone to figure this out.....

Thanks JulieInNZ,


Unfortunately that wasn't the problem with me. I had updated iTunes the day before and my pc had been off before I downloaded and tried to install ios6. Still no joy with it either. Been without a phone now for a day and have also spent 35 minutes on the phone to Apple support without any success. Not sure where to turn next.
