Venu 3 loop update !?

Hello! I would try a Hard Reset on the device. The steps are below

1. Press and hold the top side button for 15 seconds until the screen turns black.
2. Disregarded any messages that may appear on the screen.
3. Once the watch is off, press and hold the top side button for 2 seconds and let go. You should see a triangle appear. Wait for watch to complete bootup.

 If that does not resolve the issue, Please use Garmin Express to update your device. You can find the steps to do so in the following article:
