Hi,

I have an Invalid Imei problem after flashing the stock ROM (downloaded from this forum) and the serial number is gone too (well, I still have it but it's just 012345ABCDE number so...). Even if I can set my IMEI back with exposed module I still don't have any mobile network. (I also wanted to try to set my IMEI with MTK EngineerMode but I have no "CDS Infofmation" in Connectivity partition). I guess I damaged my nvram and i would really appreciate an advice please

Thank you
