Got this today with new props on the Mavic Mini in perfect flying conditions, so add me to the list! There is ALWAYS something!!! It's as if... you know... they never really test the firmware before being released! Not good enough Dji!!!

Grrrr!!!!!!

What happened when you replaced the propellor?

"What happened when you replaced the propellor?"

Lol

did you do what the error message asks you to do? The rear propellers are the reason for the uncommanded descends we've been seeing with the Mini.

Actually very much more probably you didn't check your propellers before flying!

That error usually supervenes for rear upper motor rpm reached, actually meaning the props aren't producing enough lift.
You could have checked before opening another thread, there are already a hanful of them open, all on the same topic.

The props are too flimsy. Assuming this was for weight savings but they are super flimsy. Does anyone not find it a coincidence that everyone is reporting the rear left props? Even more shocking that once replaced the error goes away.

Hi, this is a new notification added to the new firmware. Please check the propellers and see if any of them have damaged or get severely bent, if so, please change the propellers.
If the propellers got slightly bent because of improper storage, please try to smooth the propellers and test again.
If the error persists or appears frequently, it is suggested to send in the drone for diagnosis.

Hi,

There is another thread speaking about this issue (very long thread actually), and in which, a lot of users have the same issue.
A lot of them upgraded their firmware again using dji assistant and the problem disappeared.

Those who still have the issue after changed their propeller and again, problem solved.

Try this and tell us ;)
