Are you getting "an unknown error occurred (1)" when trying to downgrade from 1.1.3 to 1.1.1? The problem may lie in your timing. 1. Get your iPod to connect with iTunes in it's normal mode (not the DFU mode or whatever) 2. Press and hold both the home button and sleep button simultaneously 3. Let go of the power button AS SOON AS THE iPod disappears from iTunes. Continue holding the home button 4. Let go of the home button AS SOON AS THE iPod reappears in iTunes 5. Option click restore 6. Select your 1.1.1 ipsw 7. ??? 8. PROFIT!!! Seriously. Time it right and you're good to go.
