Firmware file labelled IOT73 version 3.3, noted as tested OK, in a 2.79 MB RAR archive without a stated brand. The name identifies a board or product code and a firmware version but nothing about the manufacturer, so the technician must confirm the IOT73 marking on the actual PCB before use. Typical use is reprogramming a SPI flash with a hardware programmer to recover a non-booting unit. Always save the original chip contents first and confirm that the extracted image size matches the chip capacity.
