[Q] No LTE at all (Verizon Variant)

so i have a Verizon one max running on T-Mobile but i cannot get an LTE lock at all , my girlfriends phone has 4 out of 5 bars on LTE but this phone for some reason will not grab signal. Edge works perfect HSPA/HSDPA works perfect but when i go to the *#*#4636#*#* menu and select LTE ONLY it still won't get any signal at all. I've tried this on stock while still S-ON , i tried it on 5.0.2 Sense 6 , and i've tried on CM 12.1 none of these roms will get LTE, what gives ?

also today i tried changing the NV values for the LTE Bands to support T-Mobile bands 2 , 4 and 12 but still no signal.
