I bought a Garmin Forerunner 255 watch that I want to use only with Gadgetbridge. There is an old software version on the watch and I want to update it and I don’t want to connect it with Garmin Connect or Garmin Express app?

I have looked for the possibility to do an “offline” update but have not found it. Maybe the community will help?

    You’ll need to find someone sharing the gupdate.gcd file for firmware 21.22. You can drag and drop those onto the watches storage.

    Alternatively, use the desktop app to install ovwr USB?

      The latest version is 22.24 but I can’t find it anywhere gupdate.gcd file. As I wrote I don’t want to use the Garmin Express app.
