    R your shsh codes backed up? If yes, is your hosts file pointed to the shsh codes?

    I do have my shsh codes backed up, but I never had to point my the host and I have restored multiple times in the last few days/weeks

    Alright something seems to be stopping me from restoring my iPod Touch because I tried to restore to 4.0.2 and 4.1 betas and it still gives me error 21. Another Thing that I just noticed was that when it says "preparing ipod for restore", the recovery mode screen flashes, then reboots. I also can't manually get it to STAY in recovery mode.

    FIXED!!!!!!!!! Had to create a new user account on the same computer, and it successfully upgraded. No more jailbreak for me.
