Hi so basically I was updating my iphone from 4.1 to 4.3.3 but right at the end the iPhone restarted and was put into DFU mode (itunes icon and usb) ive tried using tinyumbrella and recboot however neither have worked, so as a last resort i tried to restore it however an error message came up with 3194. Is there anyway i can get the iPhone out of DFU mode and if not is there a way I can restore it? please help me! thanks!
