Failed to upgrade my iphone 3G singtel set to f/w 3.1.
The itunes indicated that my iphone has to be restore, so I proceed the restoration, but restore fail as well, error code 1603.
I've tried restart my pc, plug the iphone into the rear usb port. Both didn't work, same 1603 error code. Anyone here face the same problem?
Reinstalling itunes9 now, see if that solve my problem.
Updates: Problem Solved
Restore using a new user accountCreate a new user account on your computer and try to restore while logged in as the new user. iTunes will download a new version of the software restore file. After creating the new user, log in to that account and open iTunes and attempt to restore to see whether the issue persists in this new user.
hey. i experienced the same issue while trying to update my iPhone. turns out the problem is less complicated than i thought. well i hope its the same scenario in your case.
my phone was connected to a ubs hub before being connected to my mac. i dont knw why but once i took the usb out and connect it straight to my mac, the problem was solved. no doubt, they still asked me to restore my iphone but everything in the phone is already backed up. so after successfully installed v3.1, you can restore your phone back to how it was, it will prompt you.
hope it works out for you.
