There seems to be procedure at the end of this videoz:
I know there are earlier versions of the software as well
QUOTE="Fly Dawg, post: 1391815, member: 60700"]To my knowledge the Assistant only works for P4's and above. It will not work for the P3 or P2 series.[/QUOTE]
What do i use then after a reset to restore firmware
There is a version 1 of the software
DJI's website has a complete listing of all versions of pretty much all firmware. Yes, I know there is a version 1 of assistant, but it is not compatible either as far as I know. I know that neither work with a P3. So I would assume the same for the P2.
