    I recently had a scare with my new jailbroken ITouch 2g 8Gb running 3.1.3 FW. I wanted to un-jailbreak it and downgrade to 3.1.2 and that's where my problems began.

    Tried restoring in DFU mode several times but that didn't help!

    1)The device got stuck in recovery mode and wouldn't boot up
    2)If I tried to restore it with the 3.1.3 ipsw I got the dreaded 1604 error
    3)If I tried the restore it with 3.1.2 ipsw I got the 1601 error
    4)If I tried to restore with 3.0 i got error 20.

    Went through literally hundreds of posts on this site and nothing seemed to be working.

    Here's what worked for me:
    1. Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
    2. Restore and wait for error 1604.
    3. When prompted, click OK.
    4. Close and re-open iTunes while iPhone remains connected.
    5. iPhone should now be recognized in Recovery Mode again.
    6. Try to restore again.

    Hope this helps a little.
