Unroot / hide root ?

[karako]

I wish to use a TV app, but it complains about the device being rooted.
I've been searching for a solution, but I read replies that it still doesn't work after unrooting, and that it may leave stuff behind. I am afraid I would later not be able to try hiding the root.
Also I couldn't find a way to hide root on my device.
Anything that works?
Thank you!
