Looking for BIOS flash file for HUAWEI MateBook X Pro 2019 (MACH-WX9)

[maanee11]

Hello Everyone,

I have HUAWEI MateBook X Pro 2019 (MACH-WX9) whose BIOS got corrupted i beleive. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need BIOS bin/hex file which i could use to reflash it externally via the flasher tool.

It seems like the support page of this model no longer exist: https://consumer.huawei.com/be/lapto...ro-2019/specs/

In the website, you can only see specs etc.

I have not tried to extract the BIOS dump yet as I want to see if there is any ray of sunshine to recover this laptop. The current BIOS version showing up is 1.37 and i dont know if it is the latest.

About the issue, the system prompts no Boot device found even though i installed fresh working SSD which can be seen in BIOS but the Bootable device menu is empty (See attached)

if someone already have a BIOS bin/flash file for this particular model, please send me a copy. I dont care which BIOS version is it but should be a working one.

Look forward to your reply and help.

With Regards,
Brecht

post S/N, full name and model, motherboard model, ,etc.

post the contents of the bios chip even if it is corrupted..

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

It's written on the motherboard

Update:

for the board Number: SP1MACHW19MVER.BRFHF
and for the BIOS chip MXIC MX25U6473F, this bios worked!

You can only program it by desoldering the chip because of the pinout type
