Tutorial: Root Shield Android TV (Pro; 500GB)

This has been updated to handle Oreo 7.2.2 and tested. SuperSU has been superseded by the Magisk root tool. If you’ve done this before, you are simply changing out one zip file and installing an APK file when completed.

DO NOT ATTEMPT TO FLASH THIS TWRP. Only use it to BOOT to TWRP for rooting purposes

Note: The hardware of the Shield Android TV Pro has not changed between 2015 and 2017.

We are rooting the Shield Android TV Pro running Android 8.0 (aka Oreo Shield TV 7.2.2+).  This should work on all builds of Oreo moving forward.  Looking for the Shield Android TV (2017; 16GB SKU) tutorial?  Click here. Looking for the Shield Android TV (2015; 16GB SKU) tutorial?  Click here.
