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?
Just use the regular Garmin account and Bluetooth to your phone every 2 weeks to sync for health data use storage scopes and permissions to stop unwanted data collection, use privacy settings in the app, fake account. Be done. Never use support they will dox you.
