    Huawei Matebook BIOS update with Linux

Tested with Huawei Matebook X Pro (MACH-WX9)
This is more or less a step by step tutorial, written 02/2021. Sadly at the moment Huawei does not ship a package in Linux Vendor Firmware Service.
WARNING

Please note that you can damage ("brick") your device if something goes wrong or is done incorrectly. This is for the advanced user! I can only say that I flashed the new firmware 0.1.33 to my MACH-WX9 successfully.

Side-Note: BIOS version of firmware 0.1.24 does not match the firmware version. With firmware 0.1.33 Huawei shipped also BIOS 1.33.
Install Firmware Packager

sudo apt install fwupd # the packager script is shipped with the fwupd package, at least with the package in Ubuntu Bionic.
sudo apt install gcab p7zip-full python3

Packaging Step

Find the UEFI FD File

Important: You need to tell the packager where to find the UEFI Flash Descriptor ("FD"). The location changed since 0.1.24, now with 0.1.33 you find it like this:
7z x MateBook_X_Pro_BIOS_1.33.zip
cd MateBook_X_Pro_BIOS_1.33/
7z x MateBook_X_Pro_BIOS_1.33.zip
7z x MHIKR133.exe
7z x BIOS_1.33.exe

There it is: UEFI_FW.bin
Check, if there is an FD file layout inside:
7z l UEFI_FW.bin

                               7543280      7543280  5 files

Create .cab file with the firmware

An update requires a reboot to complete. Restart now? [Y|n]:

Then the system needs to be rebooted and F12 must be pressed, to choose booting the updater, which is located on the NVME (EFI Partition) in the menu.
