I know this sounds crazy but I fixed my issue. The symptoms were as follows;

Could not connect to Gimbal
Camera was blurry
Updates failed at 40% with the aircraft rebooting every time

It turned out that the SD card I had was causing issues with the Gimbal connectivity, camera focus, and the firmware updates. What is really weird is that the 32GB SD card that was giving me problems works like a champ in my P3P. After I switched back to the 16GB SD that was working with my Mavic Pro, the upgrade finished and everything worked again (Camera focus/Gimbal connection and control, etc)! Hope this helps someone out there.

What’s the deal with the update DJI go 4 to v4.3.16? Can’t update my smart controller, unusable at this point. Missing some great waves now! wTF!!!

I've tired all of the above and have not been able to successfully update the firmware. I've even tried on 2 computers as recommended above.

Am I the only one?
