Why It Issues?

This methodology creates a backup of the firmware and configurations in a single file. This makes backing up and restoring simple.

In my restricted testing, I efficiently switched between two completely different Betaflight variations, retaining all custom-made settings. I additionally tried switching between Betaflight and iNav in just some clicks. The method took solely about 30 seconds, making it an efficient and environment friendly strategy to backup and restore.

This methodology ought to work with any Betaflight/iNav flight controller utilizing STM32 processors, however I’ve solely examined F405 to date.
