Tag: Root

To start, you will need a few tools and files.

• adb and fastboot (Android SDK tools)
• SuperSU files.
• twrp images – credit to Steel01

Make sure to back up your device in the event something goes wrong and preserve any of your data.

1. Once your TV shield is up and running, head over to the settings.

2. Go to About (First Row) and scroll down to “Build Number.”

3. Here, click “Build Number” 7 times. This will enable the developer options.

4. Now go back to the previous screen (settings). You should now see the developer options in the second row at the end.

If not, you may need to wait a little and reload the settings screen.

6. Go to Developer options to enable USB debugging and plug in your OTG cable to your device and computer.

7. Navigate to where your adb and fastboot folder and type in:

./adb devices

You should see your device.

8. Once that is working type in:

./adb reboot bootloader

A word of caution – the next steps will erase any data you may have.

9. Check if your device is connected.

./fastboot devices

10. Type in:

./fastboot oem unlock

A new prompt will be displayed. Click continue by tapping the power button on your shield TV to navigate to “continue” and holding the power button to select.

** On the pro (500 GB) version, the unlock takes more than an hour. For the 16GB version, it takes a few minutes at most.

You may need to repeat steps 1-9 to re-enable the debugger.

11. Now navigate to the directory where you downloaded SuperSu and type in:

./adb push supersu.zip /sdcard

Note ** if an error comes up for /sdcard, try sdcard/

12. Now type in:

./fastboot boot < path to twrp image>

OR to keep the stock recovery image or you could flash it with:

./fastboot flash boot

13. Select “Install” and navigate to the SuperSu.zip file you pushed onto the SD card. Click it.

14. Once that is done, click reboot.

Congratulations, your device is now rooted.

If your device becomes unbootable, but is able to boot up to the Nvidia logo screen, please follow this guide.
