The Devialet deletes 2 files after a Firmware update, this is so that if you put the configuration and Firmware on one SD card and leave it in the amp, the amp does not repeatedly update the firmware when you power down. If you have dual mono, you need to lock the SD card before updating firmware in the first amp, assuming you want to update both amps with one SD card.
