Loading firmware is quite easy, Open the Mimi App, and camera, and it gets loaded with minimal steps:
1 DJI Auto firmware does not format the card, or place the Bin file on the card, its done directly through the app.
2 Preparing the card before download only with the memo app auto download disabled.
3 have the batteyr a minimum of 50% and ready for DL
4 Save  the settings, write down all customes, Pro exactly how you had your camera to your Liking! Save files and then format  and ready for  firmware, by going back and selecting download.



Once the Camers  firmware has been updated, its best to;

A) Format the card,

B) Factory Reset the camera

C) Reload all settings back in.

D) bench test the camera  by going through the camera, turning on and off and snapping some shots for a few minutes.

Once satasfied, your Camera should be trouble free.  If any  Bugs and issues caused  should be reported to DJI, if no bugs and issues are reported and just posted,  this clearly  sends a 100%  trouble free camera is on the market


Hope this helps out.

What are the steps to "C) Reload all settings back in." ?
