Update PureBoot
===============

Purism periodically releases firmware updates.
To see the changes in each firmware release, check `the changelog <PureBoot_changelog_>`_.

Librem 11 ships with PureBoot Basic.
PureOS requires the Wi-Fi and Bluetooth device firmware from PureBoot's blob jail.


.. _l11_pureboot_update_download:

Downloading the update
----------------------

#. :ref:`In a terminal <pureos_terminal>`, create a directory for the utility script: ``mkdir ~/updates && cd ~/updates``
#. Get the utility script: ``wget https://source.puri.sm/firmware/utility/-/raw/master/coreboot_util.sh``
#. Run the utility script: ``sudo bash coreboot_util.sh``
#. Action: 1 - Update firmware using precompiled image
#. Firmware type: 2 - PureBoot (coreboot/Heads)
#. Device: just press **Enter** for default - Librem 11.
   This downloads the PureBoot update file, saved in a  ``.zip`` file format.
#. Save this file onto a USB flash drive, then leave the flash drive plugged in
#. Reboot into PureBoot


.. _l11_pureboot_update_flash:

Flashing the update
-------------------

#. After the PureBoot logo appears and it says it will boot automatically, press a key such as Spacebar to enter the menu
#. Select **Options** > **Flash/Update the BIOS** > **Flash the firmware with a new ROM, retain settings** > **Yes**
#. Select a disk/partition if you are prompted to choose one
    * There is usually no prompt for a single flash drive containing only one partition
#. Select the ZIP file that was downloaded
#. Select **Yes** to confirm the ROM
#. Wait for the flash to complete, then select **OK** to reboot
#. Wait 60 seconds for memory training to complete
    * The screen may still display the output from PureBoot shutting down.
      This is normal.
