Updates this to Canadian firmware to to UM designation. got it to Android 12. Worked fine except for Network error NT code FFFFFF at start up.
As I cant find anything about UMW model, I flashed to EMW - Taiwan Android 12 all working no NT code issues.
Whoever refurbished this mob did a job on it to show UM, and Sim IMEI says it is an LG wing!! wish I had these skills!
