Automated rooting procedure completed!

But when I open the SuperSU application, the message "Root undetected". The Root Checker Basic app also can not confirm that my phone is rooted.

I could see the custom TWRP recovery in the rooting process, but after rooting I can not open it myself. When I go to Recovery, I see Stock Recovery (which has no options such as complete factory reset, cache removal, dalvik). cache and erase data / factory reset).
