    Default Downgrade Error 16xx Fix?
    Hey guys, I located my SHSH blobs, using TinyUmbrella, on my iPhone 3GS and I started to restore my iPhone back to firmware 4.0.1. I turned the TSS server on and after 5 minutes of "Verifying iPhone Restore with Apple" or "Preparing iPhone to Restore" it gave me an error, 16xx. After waiting forever, the verification either never stops rendering or it stops the restore process.

    I then learned that I should put my iPhone 3GS into DFU mode. Hoping it would work, it came out to the same conclusion.

    Is there a fix for this?

    Thanks.
