For Firmware 13.2.0 you should unzip the file and then from within that folder copy all the files, 12 .hex and 2.txt files directly to the root of the SD card with nothing else on the card. Then pull the power cord out, insert the SD card, plug the power back in. If I remember correctly it doesn't work by just turning it off using the button on the front. Each 250 Pro has to be done separately.
