Hello, I've tried the procedure multiple times, the app asks to update the firmware, I agree, it goes to 20% "uploading to drone", the drone starts flashing yellow, then green, then the app states "Firmware upgrade failed, turn off and back on both radio and drone and try again", doing this just keeps triggering the same error.
I've tried copying the zip file on an SD card, turned on and of the drone with radio on and it did the trick, just for you to know.
