This is not my first rodeo, evidently DJI keeps forgetting how to do a simple upgrade. What were they thinking with a bin file and put it on a card and boot and hope the firmware sticks... Seriously they should stick with the Windows/Mac apps they have already built for this... I did as the instructions suggested when I got my new P3 Pro today and when it finished it just beeped constantly - would not stop.. Irritating (and loud) as hell. Got DJI support via web support and they said - oops! Bad update of the firmware.. just reflash.. Problem was it wouldn't stop beeping.. Short version: They were right; I formatted up the SD card again, put a new firmware on it, popped it into the slot, made sure the RC was off before I turned on the P3 and ... in-spite of the constant beeping..(I put it in a closet) 15 mins later it stopped beeping then D-D,D and Poof! all done. So if your getting that constant beeping - reflash. It works. Just be patient. Lastly the good: AMAZING flight and controls. I have a Phantom 1, 2 (FPV w/ Gopro 4) and Vison, and now P3 Pro. With the video down & controls this simply STICKS in the air - I mean NO movement. I did a quick test video and my wife came in and thought it was a still photo - nope - P3 sitting at 200 ft - motionless. Hats off DJI, you did good. This is by far the most impressive piece of kit. I had plans if this didn't go well I was going directly to a Inspire.. Nope don't need to, I have one.. its called a P3 Pro.
