    Earlier I was installing a Cydia hack, but it became frozen during the package installation.. so I figured I would restart my iPhone 4S.
    What a mistake!

    Now my iPhone 4S will not get past the boot logo.

    I have tried restoring while in DFU mode, but I only receive error messages like the on included below (The iPhone "iPhone" could not be restored. And unknown error occured (21)
    Is there something I can do to restore or am I screwed?

    P.S. I also have my SHSH blobs saved to TinyUmbrella if that means anything.

    (sort of) fixed the problem!

    I entered DFU mode and restored from my Mother's Windows computer instead of my Mac!
