Un-rooting stock rom would make Gearvr work again ?

I used to have a rooted Lollipop stock rom and then got the gearvr and it didnt work until I re-flashed the un-rooted firmware again , this caused me to reinstall everything from scratch , now a friend suggested i should try un-rooting option found in KingUser or SuperUser whenever I needed to use Gearvr (untested , just a thought).

so anybody tried this ?

I just dont want to have to reinstall everything once more , its pretty much annoying :)

Thanks in advance :)
