Firmware dump for the board numbered 6050A2823301-MB-A02, packed in a 3.67 MB RAR archive. The 6050Axxxxxxx pattern is used by Inventec, and the MB-A02 suffix marks the main-board revision A02. The name does not state the laptop model. A technician writes such a dump to the SPI flash with a programmer like the CH341A to recover from a bad update or no-boot fault. Save the original chip first, confirm A02 on the PCB, and make sure the image size matches the flash chip capacity.
