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?
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.
