[Moto X Q&A] yahya69:
My son's Moto X with unofficial Lineage OS 13 has been working just fine until today, when it suddenly stopped finding any network operators. The SIM card is still recognized, I may enter the pin, but then it says "No service", and when I go to network operators choice, I find that not a single operator is displayed.

I tested the SIM in another phone, it seems to be fine. I also inserted different sim, which I know to work into this phone, but that did not help.

This is what I get from adb logcat, but I can't make sense of it:

Could it be that suddenly the hardware has become faulty? Does anybody have suggestions how to test for the cause?

Thanks very much in advance!!!
