Thanks for the info!

Thank you!
Additionally, if this doesn't work, make sure you have GPS enabled on your phone/controller, as in the new firmware Remote ID is introduced and requires pilot location to be known. If you get Remote ID error and refuses to takeoff, this is why.

Thanks for the info Mindy.  

It's not 1.9.9(1000) that is the solution!!! It IS 1.9.9 (1010 official )

Thanks for the info

Please try to calibrate it through the DJI Assistant 2 again. If it still failed, it may need to be repaired.
