Hello yesterday i get my new dji mini 2.

i make a first flight with the dji fly app (version 1.3.1) and everything works.

today i need to update to the version 01.02.0300 i connect my smartphone (iphone 11 pro) with the controller and the mini 2 and download the latest firmware (01.02.0300).
the download works but the installation only works until 95% and cancel the installation. and error code 4000 please try again but nothing works....

i check with the dji assistant but there is no support for the dji mini 2 for the firmware, only the controller i checked and it is updated.

what i dried:
- restart of each part (iphone, controller, mini 2)
- new installation of the fly app
- with the iphone XR from my wife (same error only until 95% of the installation)
- disconnect from wifi & bluetooth

who could help, what could i try?
thx a lot

i never had this problems with my mavic air, before i used the dji go 4 app

Error code 400x usually is from gimbal...did you removed the plastic protection? Try to update the remote first, using Assistant 2 and a PC.
