Default [Q] No sim error and CSC unknown

I am trying to flash CM11 from Maclaw, but when I reboot, I get a no sim error and CSC shows as unknown.

I have rooted my S3 mini. The stock ROM is customised by Three UK (H3G). On stock the CSC is i8190NH3GALL2. I have unlocked the network carrier so that I can use other network sims.

It seems I am losing the CSC code when I flash with CM11.

Can anyone help me updating the CSC code after I flash CM11 or pulling the CSC code from my stock ROM to upload after I flash?
