Thanks for any input folks. I connected the Phantom 4 aircraft to DJI assistant on my PC today to look over all that’s available in the software. It connects just fine but I keeping getting “can not load firmware list” message. I’ve only connected to DJI assistant once last week when I received the Phantom 4 to register it and it worked fine. I don’t want to hit the “restore factory defaults” button because I’m not sure what it’s going to do my Phantom 4 is flying perfectly. Appreciate any input and Happy and Safe New Year All !
