iPod 2nd Gen MC Downgrade Problems

[IPOD2GMC2008]

Hi

I've got an iPod 2nd gen MC running IOS 4.2.1 and I want to downgrade to the original IOS 2.1.1 Firmware. I either get error 20 or error 1601 when restoring from ispw in dfu mode from itunes. Is there anything I can do to fix this problem?

I should also add i am not able to get the ispw blobs because tinyumbrella crashes and when i finally got them through that website there was no blobs for ios 2.1.1
