Hey i'm trying to downgrade my ipod 2g ipod mc model from 4.0 to 3.1.2 or something that i can jailbreak easily. but when I download the firmware and put my ipod in dfu or recovery mode. It extracts the firmware and then says "preparing ipod for restore." and this is where it gets stuck and the green bars keeps going across and the ipod sits in recovery mode not doing anything. I am running 4.0 legit with latest itunes. thanks for any advice!
