    IOS4 isn't available for the iPad - it's intended for the iPhone. IOS4.2 will be out for the iPad in November. If you're using the Beta version for the iPad, I think you need a developer IDfor it to work.

    Put your iPad into DFU mode and a restore to 4.2 beta 1 will work fine provided your UDID is registered as you said.

    Provide some details about the desktop setup please. That might help...

    Also, I'm just checking because lots of people tell me they tried DFU and it didn't work, when actually they didn't know what DFU was and weren't doing it properly, you are absolutely sure you tried in DFU mode, yes?
    I've never known a properly done DFU restore to fail... If everything is set up as you said, udid registered, hosts file pointing at apple, not Cydia, and DFU mode on the iPad, then there is nothing that should stop it from working other than faulty hardware.

    I'm not exactly sure why, but I couldn't do it yesterday, either, although it worked perfectly fine today!

    No idea.
