A [[DFU]] loop only happens when you've put your device into [[DFU Mode]] (by hardware). Sometimes during the restore with your messed-up [[IPSW File Format|IPSW]], [[iTunes]] will return error 31. This indicates that your device is in [[DFU Mode]] and cannot be exited, even after attempting to reboot. This is what's referred to as a DFU loop. The only solution is to restore a working firmware.
 
Have fun.
