I just bought P3 standard. I did power tests and everything was fine. I did firmware update using wifi than tried to fly it and the controller doesnt stop beeping and flashing red. I thought the power may be low so i plug it in the wall and a minute later its solid green. I turn the controller on and power indicator flashes red and battery indicator flashes green. I read to remove SD and reformat it so i did and the wierd thing is after i turned on the dji it said my firmware was up to date. but how can that be when i just formated the SD. i can just turn on the controler with the dji off and it beeps continuously.
