Post [Q] MTK 6575 - S3 Replica GT-I9300 - No radio service

Hi to all!

This is my first post i xda-developers, but i have been following the forum for some time.

I tried to help a friend flashing a replica of an S3 GT-I9300 which he bought in Thailand.
I've done it with the SP Flash Tool and everything worked as it should.
The "only" problem is that the phone doesn't recognize the network radio (i think).
I've entered in the "Engeneer Mode" with Mobileuncle and tried to re-write de IMEI on SIM1.
But when i try that it says "Failed to write IMEI due to radio unavailable or something else."

I've tried with several rom's and allways says the same.

When the phone turns on it doesn't even asks for the pin.

Is there anything i can do to save the phone?

Thanks in advance!!!
