Warning

If your device has hit AUE (Auto Update Expiration), you will not be able to revert to chromeOS.

  2. Connect to WiFi.

  3. Open a terminal, then update and install curl.

    • Use the distro's package manager to install it.
  4. Obtain your ROM backup.

  5. 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.
  6. Choose option 2: Restore Stock ChromeOS Firmware.

    Tips

    If, for whatever reason, lost your stock firmware backup, Use an additional drive to flash a recovery image.
