Hi my iphone 4s (ios 7.0.4) will not factory restore - i am using dfu / recovery mode but itunes will not allow the phone to restore or update. It gets the error 'an error has occurred (2003)'. I have also tried resetting my hosts and the shift update thing. Is there any way i can restore the phone to factory settings and clear everything from it. I want to sell my iphone 4s but cannot because it will not delete anything etc.
plz help
