We received a Phantom Pro 3 from a friend who no longer wanted it. When I try to update it to the latest firmware (1.11.20) it fails. The first time it was updating for around 15 minutes, and then it emitted the long solid beep and would not stop. So I shut it off an tried again. Now it fails within a minute of turning it back on. I have formatted the sd card to FAT32 and put the .bin file on the card, still no luck. Here is the output  ...
