I'm trying to update my firmware to 2.2.1. I've created my custom firmware for it, I put the iPod Touch into dfu mode, then connect it to iTunes, alt-click find my custom ipsw, it starts to extract and install then it pops up with an error number 1600. Any explanation? It won't do anything but this. EDIT: I've tried the automator program, didn't work. I've tried the IOUSBFamily package deal, didn't work (unless you have to use iTunes 7.7 then I don't know), and QuickPwn may be a last resort. But the problem with QuickPwn for me is, as soon as the iPod is in DFU mode, I plug it in, quickpwn sees it, brings me to the find your ipsw step, then immediately quits. Please can anyone help me? Anything is appreciated.
