Unofficial scripts to copy SuperSU files to an Android system image on Chrome OS

Be aware that modifying the system partition could cause automatic updates to fail (unlikely), may result in having to powerwash or restore from USB potentially causing loss of data! Please make sure important files are backed up.

Download the SuperSU zip manually. The link in the script now redirects to a download page instead of being instantly downloaded with "curl" or "wget". Also note that trying to root ARC++ (Android 9, CrOS 77+) will make the container bootloop with signal 9 (project abandoned)

If you use Chrome OS 77+, try this: github.com/gerriarob/arob. This project is used for Chrome OS on custom setups with Brunch framework, but make sure your PC runs an Intel x86_64 cpu and back up all your data first.
