Hi all,

I just had a brief flight in my bedroom after updating to the latest firmware, and a crash. Now the drone won't turn on. The same happens with any of the 3 batteries I try, and if I put the drone itself on charge with a full battery in, for a minute or two the first two lights flash in a way that implies the battery is at maybe 25% and charging, and then after a while the 3rd and 4th lights flash together 3 times, and then pause, and then repeat.

I guess something is broken, and I don't know what to do now?

Cheers,
Mike.

Check the manual, they give detail on what the lights mean, that should provide some help.

Open up a repair ticket with DJI.
