I am on the VM SPH-L710, not triband. I have the NDC baseband.
Wiped /data /cache /system
flashed the 0204 CM13 ROM, Open Gapps, booted, flashed Moped Ryder's VM APN fix, rebooted, flashed 0204 CM 13 ROM again, rebooted.
Except as below with camera and phone all works very well. LTE, WiFi, BT all work no problem.
Camera worked at first, then I got "unfortunately, camera has stopped" error. Tried wiping cache and dalvik, no-go.
Bluetooth Media Audio works dandy.
Phone works fine without BT. Works very quirky with BT:
If speaking on an existing call and connect to BT mid-call then it works
If I try to dial out or if I get an incoming call while connected to BT then the phone hangs then reboots.
Not sure what to do with that info, so posting here.
