HI, Could use some HELP!!! I recently installed v1.4.0 on phantom 3 professional, the v 1.3.2 worked flawlessly. I think I may have installed it correctly the first, text file said success. Anyway I did not believe to be correct and did not turn on RC. Instead I reinstalled the 1.3.2 version. I formatted the card, put the bin file in correctly. It Made loud continuous sirenlike sounds, but eventually it calmed down. Since then I have tried new SD cards, downloaded the 1.4.0 file and tried several times to install on quadcopter with RC off. I did the All RESET option on RC as well. When I insert the new file, the LED Lights on Arms flash Yellow and the Red Led stays constant. For a few seconds the camera stays level and then droops. The Camera Status lights flash Green and Red, BUT there are NO DDD or any sound at all from unit. I called Dji Support, but no help, just said send in unit. I've left the unit on for several times over an hour, but no update. ANY SUGGESTIONS PLEASE
