I've downgraded to 1.0.2

Perform HW unlock with testpoints

Restore to 1.1.2

Restore to 1.1.1

Wi - Fi is present but can't connect to any network, so downgraded to 1.0.2 activate and jailbreak with iNdependence, but the phone continues not to connect to any network...

Before HW unlock it did with this same network....

What should I do?

Thanks
