How would I go about fixing SIM card not registering after flashing a custom ROM made for a clone of my device So, I have a BLU Life One X, which is a clone of the Micromax Canvas 5 and a few others.  I've installed a ROM made for the Canvas 5, after making a bunch of mistakes, including wiping my entire system.  The ROM is working just fine except for the actual phone part, which is not registering the SIM card.  WiFi works just fine.

More details here.

Cheers,

Neveraht, or whatever my name is on here.
I fixed it by doing the following:
Wiping Dalvik/ART Cache, Data, System, and Cache.
Flashing the ROM (Resurrection Remix).
Flashing the kernel fix.
Restoring Tee, NVData, and NVRam from my TWRP backup.

See this XDA thread for extra details.
