Try disabling SELinux from viperfx settings (developer mode) and turning on master power (after installing the drivers). Before installing the drivers change audio_effects.conf to audio_effects.conf.bak in vendor/etc.
Help, I just flashed the cameramod zip file and reboot but the camera app doesn't change. If i try to install the camera app manually it said "The package conflicts with an existing package by the same name."
I'm using LOS 14.1 official 14th August build.
