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?
It does not really answer OP’s question, but there are alternative OSs for consumer devices. I found one: https://wiki.asteroidos.org/index.php/Category:Watches
I know the project and keep my fingers crossed for it, but they currently support very old watch models that are not sporty.
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.
Just curious, what features work and what do you have to miss out on by foregoing Garmin connect? On their website Garmin devices are generally listed as partially supported, and I’m not sure what that entails.
The official website is not updated particularly often so I check here https://codeberg.org/Freeyourgadget/Gadgetbridge/commits/branch/master/search?q=garmin&all=
Thanks, I’ll keep an eye on it and consider if I should give it a shot.
Try. What do you have to lose?
