    I downloaded the 4.0 firmware, but when I tried to restore (shift + restore -> select the downloaded firmware) it said there was an unknown error. Is there any other way to downgrade?

    i don't have shsh and yes, i downloaded the correct version.

    the error was unknown. i looked on the website about the error and it showed nothing about it.

    oh, and i have the newest version of itunes.

    If you dont have your shsh blobs for 4.0 you're no longer able to downgrade to 4.0
