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.
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.
