If you own a Garmin GPS watch, you may want to power it down for a while. Users on Reddit and Garmin’s forums (via The Verge) report that a botched software update is leaving the wearables in a “blue triangle” boot loop,

Garmin’s instructions seem to suggest that devices will need to be factory reset if a power cycle does not work. Reconfiguring a watch from scratch would be inconvenient, so it might be worth waiting to see if Garmin can issue an update that resolves the issue. If you cannot wait too long, you might just have to go through the hassle.

If your Garmin watch is showing a blue triangle, you’re not alone—users of Forerunner, Fenix, and Epix watches have been reporting this issue since January 28, and Garmin is looking into it. There’s now an official fix.
