Yep, bricked Forerunner 255. I started a walk and flashing triangle. A soft reset does nothing.

I'm not using beta firmware; had an update about a week ago.

Additionally the Connect app on my phone…

Is anybody else now having trouble coupling their watches with the Connect app after doing a hard reset?

Unfortunately it’s still showing the blinking triangle for me too. I tried hooking it up to my laptop but it doesn’t even show up on it.

I hold down buttons and the triangle disappeared temporarily but it’s there constantly

I tried to do this and it didn't crash/restart:

I turned off the BLE connection on my smartphone (i.e. removed the synchronization with the Garmin connect app) then I purposely started the running activity indoors and obviously it didn't allow the GPS to be hooked up (the red line remains) after about 1 minute I went outside and it hooked up to the GPS regularly without crashing and I was able to run regularly with my 255

I can't guarantee that it works 100% since I only did one test but you could try too.

Hi there! Before I was made aware of the boarder issue I followed various trouble shooting steps including unlinking my Garmin Forerunner 255 Music to my mobile. I’ve restarted my watch multiple and phone times now, have reconnected my Garmin as a new device on Garmin express (laptop) and still can’t connect my Garmin watch to my phone. Any ideas? When I went to connect support last night I was advised because my watch is discontinued I don’t have access to further support. Appreciate any ideas! Thanks.
