Firmware for an ASUS Chromebook given as C423N and C223NA, board revision 2.2, packed in a 2.63 MB RAR archive. Chromebook firmware usually combines coreboot and device-specific data, so a donor image may need hardware ID or VPD details restored. Write it to the SPI flash with a programmer only after saving the original contents. Confirm the model and revision 2.2 on the board, and remember that write-protection on the chip or by a screw or battery may need to be disabled.
