Twice in the past couple of weeks, my FR 255S Music has crapped out in the middle of an activity showing the gear / down arrow "updating" icon for a while, and then going into a blue triangle reboot loop a few times before going black altogether. If I try to restart it on the fly, it does the blue triangle loop, buzzes a few times and then goes back to black.
When I get home and plug the watch in it comes back up to the activity screen, paused at the point where the problem happened. I can then save the partial activity, but I've lost all data for the second half of the run.
Battery's not the problem...it was at 20% when it came back up at home. Firmware is up to date and auto updates are turned off, so I don't get why it would try to update itself during an activity, if that is indeed what's happening. I run with my phone, so it's possible something is getting pushed to it from the internet?
Any idea what causes this, or what I can do to fix?
Thanks,
