Root access on Tinker OS android

Before carrying out these steps you need to install Android on the tinker board and conect required peripherals to it like a keyboard, mouse, screen and connect it to a network where your computer is also connected to.

This documentation is for windows systems. Linux users need to do the linux equivalent tasks on a linux machine.

Preparing the tinker board for root:

  • Download termux.apk and install it on the tinker board

  • Download SuperSU V2.79.apk and install it on the tinker board

  • Enable developer options on the tinker board's android OS by selecting the about phone/tinker board in settings and clicking on the build number at the bottom repeatedly untill it tells you that you are a developer

  • Go into developer options inside settings and turn on USB debugging

Preparing the PC for rooting:

  • Download android platform tools for your operating system and extract it somewhere in your computer which can be easily accessed.

  • Download the rootandroid.bat file and paste it in "android platform tools" directory.

  • Download flashable Super SU zip file - Recovery V2.79 Flashable.zip and extract it inside "android platform tools" directory, not within another directory.

  • Make sure that the tinker board and the PC are connected to the same network or preferably connected to each other via ethernet.

Rooting tinker board:

on certain systems you might have to use ./ before the powershell commands

  • Open the "android platform tools" directory and right click while pressing L-shift.

  • Select "open power shell window here" (the option name might vary) or open CMD/Powershell and cd into the "android platform tools" directory.

  • Find the IP address of the tinker board by running "ip a" in termux on the android OS.

ip a

or go into "about phone" and into "status", here you will find the IP addr also.

  • in the powershell run
> adb connect 192.168.xxx.xxx:5555     (replace the tinke rboard IP address in place of the 'x')

> adb root

> adb connect 192.168.xxx.xxx:5555     (again)

> adb shell
  • Now you will get a root shell of the android system, in the root shell run
# mount -o remount,rw /system

# exit
  • Now you have to run the rootandroid.bat file
> rootandroid.bat

  • Open the SuperSU app on the android and update the binary

  • After the reboot rooting is successfully done

  • Now you can open termux in android and get root shell by typing "su" or "tsu"
