Updating Custom Firmware

NOTE

The script does not work on Windows. If you are using Windows, boot a live Linux iso, such as Ubuntu or Fedora, and run the script from there.

TIP

curl is not installed by default for Ubuntu or Ubuntu-based distros. To install it, run: sudo apt update && sudo apt install -y curl

1. Run MrChromebox's Firmware Utility Script.
   • In case you forgot, type cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh and press Enter.
2. Choose option 1: Install/Update UEFI (Full ROM) Firmware, and reboot if successful.

DANGER

DO NOT REBOOT if flash was not successful
