Firmware for a board identified only as BTC79X5 version 1.0, reported as working, in a 3.19 MB RAR archive. The name gives no brand or chipset, though the number resembles boards built for cryptocurrency mining rigs. Such a dump is written to the SPI flash chip with an external programmer to recover a board with corrupt firmware. Before flashing, read and back up the original chip, confirm the board marking matches BTC79X5, and check that the image size equals the flash chip capacity.
