New to the post, and trying to get my second hand bird up and running. Firstly, when purchased, seller said that battery, uas, and controller needed updates. Connecting controller oth drone shut off to attempt to find out latest firmware, upon opening app version say N/A. Any clue clue as to why it would not even show any firmware versions. This is my first bigger drone like this, Phantom owner otherwise, I feel like I have a very expensive paperweight on my hands. I figured if I couldn't get the controller updated no sense in trying anything else. Any help is appreciated. Thank u.
