Firmware archive labelled LOCO-M2-W, 13.3 MB in RAR format. The name most likely refers to a Ubiquiti NanoStation Loco M2 outdoor wireless unit, though the trailing W token is not explained and no firmware version is given. Extract it and inspect the contents before use: it may hold a full flash dump for SPI programming or a vendor upgrade image. Read and save the original flash contents with a programmer before writing anything. Make sure the image size matches the chip fitted to the board, otherwise it will not fit or the unit will not boot.
