Hello all, After experiencing issues using DJI GO to upgrate my P4 to firmware version 2.8.3 I decided to give DJI Assistant 2 for Windows a shot today. The drone upgraded fine, but when I tried fliying it indoors a weird message appeared indicating firmware version missmatch between the drone and the flight controller. I noticed that only the two midle leds of the DJI intelligent battery where lit on during the drone flight, and the battery leds where blinking! DJI app showed criticall low voltage warning, but the battery reported to be at 80% moments before. Naturaly I landed my drone and went back to DJI GO app, the app was reporting firmware update in process, but the process appeared to be frozen. I've now closed DJI GO APP, reset my iPhone and also my drone and RC controller. Everything appears to be working fine, the About screens report the following: App: Version 2.8.3 Aircraft: Version 01.01.0411 Remote Controller: Version 1.6.0 Could you please confirm I've got the latest firmware version of my drone and the remote controller? any guess of what went wrong? I'm glad that I've checked this indoors before the first flight!
