Ah, sorry! Hopefully this is better.
After logging in as root in the terminal, I get to the ChromeOS Device Firmware Utility Script with:
cd; curl -LOfk https://mrchromeboxmrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh
I pick option 2, Install/update UEFI (full ROM) firmware, say yes to the warnings, no to the backup of the stock firmware.
