after being a dji fan for years I decided to give the h a try. After unboxing and charging everything up I proceeded to update the 16 and h. The 16 went fine. Not so much for the cam and h. Not too sure what happened but the drone would not turn off and wouldn't go into bind mode. Literally after 4 hours of searching the net I found a fix. It required using the GUI and installing an older version of the firmware. After I did that everything worked fine and was able to upgrade to the latest fw. The reason I'm writing this is because what I found to be the most popular answer to this problem is that the unit has to be sent back to the manufacturer when all you have to do is reinstall an older version via the GUI.
