Custom recovery problems

[Suren Manukyan]

Guys here's the thing. Android N on my N5X. When trying to install TWRP 3.0.2.2 through Nexus Root Toolkit it first boots up the recovery then when I reboot to system and back there is no TWRP. But it remains there when I use the Root button which roots and installs custom recovery. So when I have root I have TWRP. Can't I have TWRP without root I wonder?

Have you done the 7.0 update? I was having a few issues but then did the update and everything seems to be ok.

Yup I have the update. ( Even the 7.1.1) but it still doesn't work...
