Trying to restore but receiving errors :'(
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.
