Hi everyone. I back again. I really want thank Thunderdrones for his reply to my update problem. It took 4 batteries to update MPP to V01.04.0400.
Now I have another problem. Status display in DJI GO 4 indicates a ULTRASOUND MODULE ERROR. Contact DJI for repare. My queston is this, is it an update problem or is it
an accual failure. If it is an hardware failure, then why should it be with a new drone.
Again thanks Thunderdrones.
Any help will be very appriciated.

Hello, sorry for all the trouble. Could you please export the flight data via DJI Assistant 2 then upload it to Dropbox and send me the link? We will forward the data to our R&D engineers for review. How often did the ultrasound module error occur?

Hope you get this resolved soon..all the best

Hi All

Is there an update with this?

I have recently purchased the MPP, have done all the firmware updates etc... but in the app it gives me the same message.

The drone hasn't actually been flown yet. Only in the simulator, which after I leave seems to be the time that the ultrasound module message occurs.

Might it be a case of downgrading the firmware?

Thanks in advance

Wish your drone all the best
