I am reaching out to ask for help on a problem I have been having for about a week now with my Forerunner 955 Solar. It started the day I installed update 18.26. I was about an hour into an activity, and the watch began boot looping. I managed to get out of the activity after a while, but now whenever I start any activity, 3-10 seconds after having started, the watch restarts and goes back to the homescreen. I have attempted a master reset to no avail, with the issue persisting. It does this at all battery levels and I am really not sure what else I can do. Simply navigating menus results in a crash and reboot, with it sometimes rebooting 2-3 times before reaching the watch face.
Is it possible to perform a rollback on software updates for troubleshooting? What else can I attempt?
I can supply additional information if needed.
EDIT 1: I have enrolled in the Beta program and have updated to 19.09. For now it seems to be allowing me to start an activity and bootloops might be gone. I will go out now to test more extensively. Possibly a botched installation of 18.26 caused this issue?
EDIT 2: Looks like the 19.09 upgrade fixed the issue.
