Question [Q] Can't write Akey after update to Stockl 4.3 ROM.

When I update to Stock 4,3, I can't write Akey. I try use workshop or DFS, but no result.

The AN/AAA and ESN IMSI write success. Now, I can connnect to internet by EVDO. But I can't make a call.

Does anyone know how to do it?

BIG THANKS!!!
