well... never underestimate the ability of somebody to still mess it up. Even when every update from DJI includes a PDF file with instructions. The fact that one of the precautions at the bottom says: "Do not perform firmware update while the aircraft is still flying in the air." tells me that has happened so many times that they had to specifically point it out.
If you plug in a USB with the firmware but the controller does not start beeping does that mean you dont need that update? I was putting the latest version on (which does say controller is not required) on my phantom, but I dont know what firmware was already on it. Not sure what Rev I am coming from so I dont know if I need to look for the last controller update or not before flying.
