How to get root rights in ADB?

Question

Android

Good afternoon!
We have Nexus 5 on Android 6.0: stock firmware MRA58K, kernel from here , TWRP 2.8.7.1, SuperSU_v2.52.
When trying to get root from the console, we see the following:

cmd> adb root
adbd cannot run as root in production builds

Moreover, before that I installed both custom firmware and technical preview 6.0, and dropped to 5.0 - nothing helped.
On the Internet they write that you need to edit the default.prop file , which lies at the root. And do you need to unpack boot.img ? edit default.prop in it and pack and flash it back. But that didn't work either. Maybe he didn't do it right.
So how do you run the adb root command?

Answer 1

try su command or sudo

Answer 2

Hi all. I have a Chinese phone with a very exotic processor
a bunch of viruses already out of the box. I can’t root ((((
Neither su, nor sudo, nor root.
Here are my futile manipulations
