    So summed up = You can't restore to iOS 4.2.1? If this is the problem, all you need to do is install "TinyUmbrella" and once that error pops up (0x8000001) simply leave that open, head to tinyumbrella, and click force out of dfu. I didn't quite understand the question, so if this does not help whatsoever, please reply a little bit more detailed.

    If you're restoring to 4.2.1 without SHSHs, this could be the result of the problem. Do you have 4.2.1 SHSHs saved from before Apple stopped signing, and if so did you use them properly during the restore?
