Downgrade 2G Firmware

I'm experiencing problems with the 1.1.2 firmware upgrade for my 2G nano (resets and other weird problems). I'd never had any problems with the 1.1.1 firmware that came installed on the unit.

Unfortunately since the ipod didn't come with a CD I cannot downgrade the firmware. Apple also does not provide archived versions of their firmware. I found a copy of the old firmware 'iPod_19.1.1.1.ipsw' on the net, but I also need the signature file (presumably for checksums).

Could someone post the file or the contents of the file 'iPod_19.1.1.1.ipsw.signature'?

Thanks

Just connect it to your computer, select the iPod in iTunes, and hit the reset button under the summary tab. This restores it to factory settings (and firmware).

This allows me to restore my current firmware (1.1.2). To restore to the previous firmware version (1.1.1) requires that I have 2 files in my ipod update directory:

C:\Documents and Settings\<username>\Application Data\Apple Computer\iTunes\iPod Software Updates\

I need:
iPod_19.1.1.1.ipsw (I already have)
iPod_19.1.1.1.ipsw.signature (file I need)

Did anyone with a 2G ipod do a restore which cached this file from apple?

Thanks

I, too am looking for the contents of ANY of the ipod_19.1*.ipsw.signature files (apart ipod_19.1.1.3 as that one is freely available).
So, if you have 19.1.1.2, or 19.1.1.1, or 19.1.1.0 (with the .signature at the end), please open notepad and paste the really long key here. If you don't know how to do that, please upload somewhere (like rapidshare, mediafire) - it is a really small file.
If you are running Vista/Win7, it is NOT in the location stated above. It is at C:\Users\<LOGIN NAME>\Appdata\Roaming\Apple Computer\Itunes\iPod Software Updates

Please! I really, really need this file, and I suppose the guy above me is still searching.

EDIT: If you have anything from around the 1.0.1 era, could you UL the ipsw and ipsw.signature file? I think I may need a really, really old firmware version to get the micromemo recorder to work with it.
