[920XT] Random Restart Issue with Forerunner 920XT Watches (version 10.20) started (26/05/2024)

Hello,

I am experiencing problems with my two Forerunner 920XT sports watches (version 10.20).

The issues are as follows:

  1. Random Restarts: The watches restart randomly, especially when I think they are trying to connect to the Garmin cloud.
  2. Startup Freeze: After restarting, they always get stuck on the startup screen with the Garmin logo.
  3. Reboot Cycle: The screen stays on the Garmin logo for a few seconds, then turns off and restarts again, repeating this cycle indefinitely.

To try to resolve this issue, I manually restart the watches by holding the power button for 15 seconds. Then, upon restarting, I press both right buttons until the first beep, and then only the bottom right button until the second beep to reset the watch. Despite this, the issues persist.

I noticed these problems after the latest update to the Garmin app on iOS, but I am not sure if it's related. Here are the tests I conducted:

  • Connection to Garmin app on iOS: Once paired, the watch performs an "update" (I had time to check in the system and it's already in 10.20 so not a software update) and then goes into the perpetual reboot cycle. I am not sure if this update is an OS update or just configuration files.
  • Connection to Garmin app on Android: Once paired, the watch performs an update and then goes into the perpetual reboot cycle.
  • Connection to the cloud via Wi-Fi: The watch performs an update and then goes into the perpetual reboot cycle.
  • Connection via Garmin Express on PC: No issues. I can send data and workouts. I even completed a workout and uploaded it to the cloud via Garmin Express.

I was considering staying in this mode via Garmin Express temporarily while trying to identify the source of the problem, which based on these cross-tests, could be related to Garmin Connect. However, my watch just restarted without being connected, and I had to perform the reset again.

I am aware that the Forerunner 920XT is no longer supported, but I would like to keep using it. I just love that old and efficient watch. Are there any diagnostic tools available to me? I would also like to test reverting to version 9.X if possible to conduct more testing.

I'm sure I'm not the only one having problems since I had poroblems with my 2 watches, but a quick search on internet does not lead to any other person having the same issue (recently).

Thank you in advance for your help.

I am posting this on a forum dedicated to newer watches, knowing that this issue concerns an older model that is no longer supported, but I would like to keep using it.

    Just quick update after having done a few other troubleshooting sessions on my end.
    The problem appears only when my calendar is filled with training peaks workouts.

    The "update" screen that appears before the watch freezes is the calendar update aparently (which was not an issue during the past 6 months).
    After deleting the calendar connection between TP and garmin, the issue is resolved.

    Now I will have to investigate what's exactly the root cause.

    Hello,

    I'm running into the same issue with my 920XT as well. I am unsure what triggers it to restart. It appears to be random perhaps. Sometimes it's a one-off. Sometimes it restarts repeatedly. My software version is 10.20 as well. This is my first time observing such behaviour. Have you found a solution yet? 

    Thank you.
