reboot loop - device not usable any more

I have the solution:
Factory Reset Instructions
Power off (press and hold Light)
Press and hold Start/Stop and Lap/Reset
Press and hold Light (three buttons should now be pressed in).
After first beep, release Start/Stop.
After second beep, release Lap/Reset.
Release Light.
Watch is now reset.

This was done in the shop where I bought the fr955.
The watch is now working again!

I have the same now with my FR955. It shows the green Garmin triangle, then after a while it reboots. This repeats endlessly. I tried the suggestion above to restore to factory default settings. But unfortunately, during that process (you see the cogwheel with a progress bar), the watch reboots again, and the endless loop is repeated. Does anyone know of any other ways to bring the watch back to life again?

Also, I tried connecting to a computer, but then the computer says the watch is not connected. Before I tried all these things, the watch has been charged for a few hours.

Last few days I had the same problem with my FR955 solar watch 

Exact same issue for me. Any advice Garmin-Kevin?

same! cant find a fix!!

Worked for me. Thank you

Did you find a solution? I have the exact same problem

No, I ended up returning the watch under warranty, and got a new one...
