I've been trying to load a pwnagetool cooked version of the iPad 4.3 GM, but whenever I try to actually load the firmware via itunes I get an error 1 that pops up as soon as the white apple logo appears on the iPad. This is both in recovery mode and DFU mode. I've tried this with both windows and mac version of the program with no success. Can anyone shed any light? I also tried pwn'd dfu mode with iREB and get the same result.
