Not sure what you meant Digi mine is a mark 1 and it updated? Unless I'm missing something?
Same problem as peterd and zeng:
My iOSD shows 0.xx beta firmware, for which there seems to be no upgrade available but the assistent nevertheless wants me to upgrade first ...
I'm probably one of the unlucky V1 guys (I bought my iOSD less than 2 months ago).
Exactly the same behavior with me. Thanks for posting. Maybe you should forward this to DJI?
Nothing. Yesterday I had the same situation as shown in the video. Today it worked. Try again, should work now.
