Having all kinds of trouble updating the firmware. Downloaded the zip file extracted the .bin to the sd card and the Phantom just sits there with the lights blinking but won't update. Also when I plug my RC into my iPad and turn it on and open the Go app it shows I have a P4 instead of the P3A with no where to change it that I can tell. Is there a reset button on the RC like there is on the gimbel on the drone? Had the drone since Tues and it's been a paper weight so far.
