I'm about to give up. My app is v. 2.20. My aircraft is v. 1.1.9+ and the RC is v. 1.1.8 everything works great. I just really want to try these new features. I for the life of me can not get P3X_FW_V01.03.0020.bin downloaded from DJI website to Unzip. Without it unzipped the aircraft will not recognize it and update. It's my understanding that I have to update to that version before updating yet again to the newest version out. If any users out there can enlighten me on how to unzip this file that would be fantastic. I've tried a few apps from the AppStore with no luck. As for now, I've been beatin.
