I was trying to update the iOS to version 6. The iPad was backed up and when trying to update the iOS 6 it errored with -1 error code. I set the iPad in recovery mode and tried to Restore it. It then gave an error code of 1604. I have tried the steps mentioned in the troubleshooting article for 1604 error and so far no luck restoring my iPad. Please help.

iPad 2, iOS 4.2.7
