    Make sure you're using the correct firmware. Sounds like you're trying to load 3gs firmware.

    the problem is that the Apple Server doesn't sign the 3.1.2 fw anymore... so you won't be able to restore to 3.1.2...

    You've now got 2 options:

    1. Upgrade with a custom 3.1.3 Fw

    2. Restore with help of a local verification server (which is a bit more complicated and you will need to have your ECDID and SHSH file backed up, if you don't have the don't even try.) --> Check This also works for 3g

    But I would suggest that you upgrade using snowbreeze (windows) or pwnage (os x) to 3.1.3

    hope this helped
