Ask Huawei NbDE-WDH9 (Board: DA0H99TB8E0 REV E HF)

[noktabil]

Hello,

I need a working BIOS dump for a Huawei laptop. The device powers on but has no display.

Symptoms:The laptop turns on, and the keyboard is responsive (I can toggle the Caps Lock/backlight lights on and off), but there is absolutely no image on the screen. It looks like a corrupted BIOS issue.

Device Details:

• Model: Huawei NbDE-WDH9
• Board Model: DA0H99TB8E0 REV E HF
• BIOS Chip: MX25L25673G @ WSON8 (8x6)
• CMIIT ID: 2020AP10393
• Serial Number (S/N): NQNPM23404000234

I have already desoldered the chip and backed up the original corrupted dump.

Thank you!

Thanks for the file.

Unfortunately, this dump (builds872.zip) didn't work. After flashing it, the laptop is completely dead now. It doesn't power on at all, and the adapter light just keeps blinking when plugged in.

I really appreciate your help!
