Q: How do I update the SpaceFlow D2090 firmware?

A:Keeping your SpaceFlow up to date is easy:

1. The app will show a pop-up when a new version is available

2. You can also check manually under Device Details > Firmware Version

3. Tap "Update Now" to start downloading (it downloads in the background, so you can keep using your SpaceFlow)

4. When the download is complete, choose "Restart Now" or "Restart Later"

5. Your SpaceFlow automatically switches to the new firmware after restarting

Simple as that!
