Hello all, I am using stock ROM upgrade from Wifi.

The phone works nicely yesterday, however today it come to emergency calls/no services, restart phone also no use.

Took out the SIM card and reinsert also same result.

Tried other sim card to my phone also cannot to register to telco.

However I am able to search for signal such as Digi, Maxis, Celcom.

What is the problem?
