Firmeware reflashing

when you should do a Firmeware Reflashing ? Can you solve the problem of a few satellites in the Rover?

You can flash the firmware whenever you want. If you have some trouble, you can reflash and see if it helps.

In a normal situation, you should never have to reflash though.

If you update to the development version and want to go back to stable, you do have to reflash though.
