I did the new firmware update today. put it on the sd card with no other info on it but the new bin file the phantom 3 pro. looked like it was taking the update like I did in the past for older updates, but this time it was taking over a hour still beeping and lights flashing on gimbal, gimbal was very hot, so I turned it off. I was going to reload the update again but to my surprise the text file said it was successful. Very odd. Hope it is fully installed so I don't have flight problems.
