How to root an Android device via ADB?

Question

Android

I enter in the terminal (Ubuntu 15.10):

> adb usb
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting in USB mode
> adb -d shell
[email protected]:/ $ su
[-] Unallowed user
[email protected]:/ $ exit
> adb -d root
adbd cannot run as root in production builds

I go google, I find adbd insecure , which seems to solve the problem. I put it, give it root rights, press enable insecure adbd, restart ADB on the computer, try to connect - now ADB stupidly ignores all commands. That is something like this:

> adb -d shell
# пустая строка, ничего не происходит, пока не нажму ^C

Has anyone come across something similar?

Answer 1

It might make sense to wait. Or press ctrl + C when an empty line appears.

Answer 2

and if my memory serves me (debugging via usb) in the developer should be enabled))
and stand superSU as it will give access to adb
