Used the expert mode with pwnage tool and now lost phone service with ATT after recovery. Any ideas as to what to do regain phone service????.
Do I need to downgrade back to 3.0.1 ?
Make sure to UNCHECK the "Activate" box in Expert Mode in pwnage tool 3.1.3 if you are using an AT&T SIM. Then rebuild your ipsw. This seems counter-intuitive compared to the previous version, but it did work for me.
