For the EFS folder, i do not have a backup
Workaround 1: disable SIM pin number. After that the network should work
Workaround 2: use an older version of android.policy.jar (from an unofficial developer release from Samsung). In this versions the check for a corrct IMEI seems to be disabled.
I have this problem myself and was lucky to get an upgrade with the so called developer imei. Since then I use the android.policy.jar from this upgrade.
But please try W1 first. If you'll get the network then it is solvable with W2.
If W1 doesn't work then even W2 will fail.
