Root 6.0 problem

[Izzxy]

So recently i updated my lg g stylo to 6.0 (through the flashable) it works and I follow the step to root it. Now when I use KingRoot it roots my device but when reboot it unroots. And when I flash SU i get stuck into the boot. This had never happen before

What do you mean "Through the flashable"? Did you use LG Up version to get Marshmallow?
