Problem with Google Pixelbook (2017 EVE)'s touchpad

Hi everyone. I need some help with my GGPixelbook’s touchpad. It stopped working at all after I reinstall ChromeOS from Windows (it works on Windows and Linux though). I used MrChromebox Firmware Utility and a Chromebook Recovery USB to install ChromeOS. I did try downgrading touchpad firmware but it’s still no response.
Appreciate you time.

This only worked for me if after I reverted back to stock ChromeOS (from backup) first — then reran the script like I was doing it for the first time. but make sure to downgrade the firmware before rebooting (after it flashes it to coreboot)
