Firmware for the Acer Chromebook CB314-1H-C8NQ on the Quanta board DA0ZBCMB6E0 revision E, packed as a 4.03 MB RAR. Chromebooks use coreboot-based firmware, often with write protection, so the chip normally has to be programmed externally or with protection disabled. Use it to recover a bricked unit by reflashing the SPI chip. Keep a backup of the original contents, which hold device-specific data, confirm the board revision, and ensure the image matches the flash size.
