Garmin says it has fixed the blue triangle boot error that was bricking some devices

Garmin has identified a resolution for devices stuck on the startup screen, commonly referred to as the 'blue triangle of death.' A factory reset or power sync is necessary, depending on the device. Unfortunately, users may lose data such as Garmin Wallet and Body Battery insights during the reset. For Forerunner watches, detailed steps are provided for users to follow to facilitate the reset. Once synced with the Garmin Connect app, much of the data may be recoverable, alleviating user concerns about loss.

"We have resolved the underlying issue causing some devices to be stuck on the start up screen," a Garmin spokesperson told Engadget, discussing the solution found for users.

Garmin has provided additional troubleshooting information for those with devices that are still malfunctioning after a power reset, with the required steps varying by product line.
