So the other day I borrowed a couple batteries from a friend who has a P3 Pro to use on my P3 Advanced. My firmware was up to date with version 1.8, but his wasn't. When I put his batteries in my craft, I think I still had the firmware update on my SD card and it updated his batteries - now his craft won't even power on! Also, my craft is now having a bunch of problems - the camera gimball goes limp after it's boot up phase, and all my batteries flash the red button on the shutdown phase for about 10 seconds before shutting down. Also, when connecting to my app, it now recognizes my craft as a P3 Pro, not advanced. What a mess. Who knew something as simple and borrowing a few batteries could cause so much havoc?! Any ideas on how to get back to normal? DJI says send them in.
