I have a 1g Touch with 2.2.1 and iTunes 8.2 I can't get the iPod to go into DFU mode. It seems to say in DFU mode for a second. Itunes says "Waiting for iPod..." then there is a series of USB disconnect/reconnect sounds, the ipod screen flashes white, then it goes into recovery mode. I also attempted to shift+restore to a custom 3.0 firmware while in recovery mode but get error 1604. Edit: I tried connecting it to my keyboard's usb port. The white screen stays but I get a system tray pop up later telling me that the keyboard's usb hub does have enough power for iboot recovery system.
