All,

Although appreciated, it's completely absurd the only guidance we have are some other users suggesting button combinations to get these devices to power back on but not resolve this issue. Where is…

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…

Hard reset and sync with Garmin connect solved it for me. Though really frustrating that no better guide from Garmin is available for this issue.

I also had this issue yesterday or two days ago. Started the run screen, gps getting ready but went into bootloop since then. Stuck in bootloop. Omg.

A few months ago, turning it off then off fixed it. But today, it didn't.

I had to hard reset the watch, delete it from garmin connect. Great... That should have never happened.......

can you explain what we are loosing after the reset?

From what I see and understand, you lose the customization of the screenwatch, garmin pay config.. Apparently there is a saving of the watch settings you can reapply after pairing.

I still have my training plan, my previous data (up until the stuck bootloop ofc). I guess it's alright.

1) Force it off
2) Press and hold Start and Back
3) Press and hold Light (now you're holding 3 buttons down)
4) After first beep, release Start
5) After second beep, release Back

I tried this a few times and still not working.

Just realised it’s because their instructions aren’t clear, step 5 should be release the back and light button at the same time!
Then it worked for me (forerunner 255s music)

But step 3 is to press the light button, not press and hold, so when you get to step 5 you only need to release the back button. At any rate, glad it's working for you.

Ensure the watch is powered off.
- You may need to hold LIGHT for up to 30 seconds to turn the watch off.
Press and hold BACK and START/STOP.
Press LIGHT to power the watch on while holding these two buttons.
After the first beep release START/STOP.
After the second beep release the remaining buttons.
