I currently have a P4 that is experiencing similar update issues. If and when I resolve this I will post it here.


GL to both of us!

I was finally able to update via Iphone directly connected to the Phantom via OTG cable.

Power on TX and Drone
plug OTG cable to the Phantom with the other end to your phone
In your DJI Go App... the top part of screen will ask you to update
this update takes a long time, so make sure your phone and drone has enough power

if my instructions are not clear please let me know.

Cheers!!!
