I am tired of trying anymore so I thought to put the question out here. My P3 controller on the app keeps telling me that I need to upgrade my firmware. Have tried every type of steps from DJI academy videos to youtube videos and still does not update. I updated the firmware on the aircraft to the latest (1.3.20) and it updated fine. Use the sd card connected directly to the controller to update it and never get the "blue" light status and it never updates. Tried updating directly through the app, no update. Tried connecting the controller directly to the aircraft with the cable and nothing... I finally called and through a painful "on hold" waiting process, talked with someone from DJI. They said I would need to send it to them so they can reset the controller, then it would work?? Problem is, they said it would take 8 weeks to get the controller back from them. What a joke! Some customer service they have... Anyway, I'm hoping that someone else has experienced this and can help me take care of it myself without having to ship it to the factory. Any thoughts?
