Upgrading PureBoot

Purism occasionally releases new PureBoot firmware. You can update PureBoot firmware directly from PureBoot itself!

To update to a newer version of PureBoot:

  1. Download the new PureBoot ROM from our PureBoot release repository for your corresponding hardware.

  2. Copy that to a USB thumb drive and attach it to your Librem device.

  3. Power on your Librem device and enter the PureBoot settings by pressing the Escape key.

  4. Head to Options -> Flash or update the BIOS -> Flash the firmware with a new ROM and retain BIOS settings.

  5. Next, select your USB device, then select the ROM file.

  6. Select yes to proceed.

  7. Your BIOS will update and your computer will reboot once done.

Note

You will receive a notification to update your TOTP/HOTP secret during the subsequent boot after updating the firmware.
