I just can't seem to get past the 1600, 1602 codes no matter what I do, I have reinstalled iTunes and cleaned out my registry my phone is in DFU mode and I'm using tinyumbrella with my shsh saved and I'm using the same exact 5.1.1 firmware version that is on my phone now and I have modified the hosts file to 74.208.10.249 gs.apple.com I don't know what else to do this has always worked for me before I don't understand why it won't work now....
