iPhone is not recognized in recovery mode / DFU (Dowgrade impossible if you are not in DFU):
Manually put your iPhone into "recovery mode": Press Home and Power for 10 seconds After 10 seconds release the Power button and let Press the Home button until you see the message "iTunes has detected an iPhone in recovery mode "
Manually put your iPhone in DFU: Hold the Home button + Power simultaneously to re-boot your iPhone (10sec). Only then release the Power button until the message "iTunes has detected an iPhone in recovery mode" (25sec).
The downloaded firmware selects or is incoherent with the version of your camera, or file is corrupt.
Re-télélcharger firmware solution for the version of the iPhone - Phone1,1_xxx.ipsw for V1 (Edge) - Phone1,2_ xxx.ipsw for V2 (called 3G) - Phone2,1_ xxx.ipsw for V3 ( Called 3GS)
