Firmware backup for the Bangho Zero M4 laptop, labelled Y116B, containing both the BIOS and the EC (embedded controller) firmware, and noted in Spanish as a working backup. The RAR archive is 3.61 MB. Having BIOS and EC images together helps when a machine shows no power, charging faults or keyboard issues caused by corrupted controller code. Identify which file belongs to which chip, back up the originals with a programmer, and match chip capacity to each image before flashing.
