I am trying to install iOS 5.1.1, 4.3.5, or 4.3.3 using my SHSH blobs and TinyUmbrella. When the restore finishes, iTunes displays Error -1. I have disabled my antivirus and firewall, and I've tried both pwned DFU and normal DFU modes, but the error still appears.

iTunes Error -1 often occurs during a downgrade or restore process when the firmware update is nearly complete but fails to exit recovery mode correctly. To resolve this, you can use a tool like Redsn0w or TinyUmbrella to kick the device out of recovery mode. In Redsn0w, go to Extras and select Recovery Fix while the device is in DFU mode. If you are using TinyUmbrella, click the Exit Recovery button. In some cases, this error can also indicate a hardware issue with the baseband chip, but attempting a software recovery fix is the recommended first step for legacy device restores.

Go to Redsn0w, select Extras, then choose Recovery Fix. Put the iPhone in DFU mode and Redsn0w will attempt to fix the error for you.
