BIOS dump for a board marked NB2686_MB_V3 in a device with model code KLVL-WFH9, listed as working and fully verified. NB2686 boards are used in Huawei MateBook laptops, but check the device yourself. The RAR holds the image for writing to the SPI flash with a programmer to recover a dead or bricked unit. Check the V3 revision on the PCB, save the original chip contents and confirm the image size matches the chip capacity before writing.
