unlocked 1.1.2 phone then updated to 1.1.4 it was automatically jailbreaked but no signal and apps so i restore again to 1.1.4 and it ends up with 1604 unknown error .

i entered dfu mode and tried to restore 1.0.2 but still same 1604 error

i tried iliberty+ and ziphone to get away from recovery mode but nothing helps...

pls tell me how to fix this

thanks in advance
