[G3 General] grymmy:
Hey guys, I'm having the same issue with regards to the NT-Code error. This is my error code: NT-Code mcc/mnc [FFFFFF], subset [55].

I have read the instructions thoroughly and tried to the best of my abilty to fix the error, but no success. My device is a D855, 32GB, rooted, stock MM. My original software version according to About phone was V20x-xxx-TWN just before I updated to V30c-GLOBAL-COM. Can someone guide me or shed some light on this issue please?

Many thanks in advance guys...

I added line 1 as seen below in my "cust_path_mapping.cfg"
