[Huawei P8 Lite (Kirin)] ROOT with TWRP 2.8.7.x

Hi All!
I found some process to a simple ROOT for P8lite on a czech board:
1/ flash TWRP
2/ in TWRP flash SuperSU v2.46 from "https://goo.gl/Ci0Yzd"

It is possible take it so simply? Try or make it successful someone?

P.S.Sorry for my english, Google helps me... :p
