My M600 Pro was working fine before this recent upgrade mess, now I get no video/drone connection using DJI Android apps. I get some functionality using the XT Pro app on an iPad mini 4, but DJI Pilot doesn't quite work on that device.  I've tried downgrading all firmware but still getting limited function with DJI apps on Android devices.  If anyone has any advice on getting all the firmware back to working versions I'm all ears.  Thanks!
