Garmin has shared new ways to fix its smartwatches that are stuck on the “ blue triangle of death ,” a boot-up error that’s been stopping owners from using their watches. The steps could get more watches working again — but some models will lose data in the process.

Since the last two days, many Garmin smartwatch users have reported that their devices have stopped working or are stuck in a boot loop with a blue triangle being displayed on the screen. However, the company has now acknowledged this issue and released an official fix.
