Firmware image in a 10.7 MB ZIP, named necn38ww.bin, with no brand, model or board number given. The NxxxxxWW pattern resembles Lenovo BIOS version naming, so it may be a BIOS or EC update image, but the target device must be confirmed separately. Such images are written to the SPI flash with a programmer like the CH341A after the original chip has been read and saved. Make sure the extracted size matches the flash chip capacity, and check that the image suits your exact board before writing it.
