Well, my new P3 Pro arrive today. I have charged up both batteries and was starting the firmware updates. The aircraft had no problem updating. It was sucessful. The RC controller will not update. I have tried putting the micro sd card in the USB on the back of the controller as well as inserting the micro sd card into the aircraft and running cables between the RC and the aircaft. I have watched the firmware updating instruction video from DJI and followed it to a tee. Nothing. The RC Controller light will not turn blue and update. It remains red. Please help if anyone has had the same issue. Thank you.
