I have the 30 gb video ipod, And all i have to do to load original firmware is hold the menu and center button, Till it reboots soon as it starts to reboot i click the hold button over and it says loading original firmware works like a charm, I have done it 5 times repeatedly just to make sure its working right and not a problem yet even if i do it when i am playing doom, I have done without closing doom just reboot and load orginal firmware!
