you should definitly format the SD card before you copy the firmware files on it. I had a similar issue some years back. I was able to copy the files on the SD card without any problem, but the update on the Devialet fails. Then I have formatted the SD card and copied the firmware files again. Then it was working fine. The message on your Devialet is clearly stating that the update fails, so I don't think you have a faulty unit.
