Archive for a four-port LAN device identified by part number BT4LBV30, marked as tested and working. The name suggests a firmware dump for a small network board, though it does not name the brand or the flash chip, so check the contents after extracting. Technicians usually write such images to SPI flash with a programmer to recover a bricked unit. Read and keep the existing chip contents before writing. Confirm that the part number on your board matches and that the image size fits the flash capacity.
