I seriously doubt if the original poster of this thread got DJI's attention. They absolutely do not care! My P4 flipped at 200 feet and powered into the ground upside down. I researched this failure every way I could and sent all this data to DJI proving that a Phantom 4 in working condition cannot flip and yet, after a month, they refused to tell me how it flipped and why. I stayed in contact with them several times a day trying to get anyone to take my proof seriously and they still refused to acknowledge that fact. Then, they sent me a new P4 without explanation, to get me to "Go Away". I did, but occasionally I find someone with a question about DJI's terrible service, or an indication that they finally found out how to deal with them! In short, you can't deal with them. My "new" Phantom finally flew because I scrounged a set of propeller spring clips that they had deliberately removed from my new P4 before it shipped as all the mounting screws were left loose. It took five weeks for the original replacement ones to arrive by snail mail. They just DON'T CARE!
Good luck,
