Help restoring 2g Ipod Touch to factory default

I jailbroke my Ipod Touch 2g awhile ago on the 3.0 firmware. But I wanted to restore it back to factory defaults, upgrade the firmware, then jailbreak it again.
I'm just having problems restoring it.
First I tried just plugging it in and restoring from apple, though it failed on the authenticating with apple.

So I tried downloading firmware onto my computer, shift clicking and doing it that way, same thing.

Then I put it into DFU mode, screen was blank so it wasnt recovery, it opened up in itunes and said I need to restore it, then I shift clicked to restore to the firmware I downloaded. If just gave me a box that said unexpected error (13).

I'm attempting to download the latest version of itunes now, but I'm not sure if that will help. The firmware file I downloaded is fine too, downloaded a few times, even tried a lower version.

The Ipod touch is a 2nd gen,8GB, non mc model on jailbroken 3.0 firmware
I'm trying to restore to 4.2.1 or even 4.1, whichever works.

Can anyone help me get through this error and restore it right? I'll worry about jailbreaking again later. Thanks

 

Got it to work.

That way to get into DFU mode didn't work for me. What I did was keep the ipod on, hold down power/home until it went blank, and then held home until it popped up in itunes that it was in dfu mode. Worked perfect first try.

From there I could restore to an updated firmware. The new itunes seemed to be the trick, even with dfu mode it wouldnt work in the older itunes.


Thank you for your help
