U-l-i-s 2 months ago

This morning i updated to sw 20.26 on my Forerunner 955 solar.

Exactly the Moment after the update all Sensors stopped to Work.

No more heartrate, bloodoxygen, compass or Temperature values are recorded any more.

Restart of the watch does Not recover the issue.

Looks Like all i2c Sensor communication is blocked.

After Reset to factory Default now stuck in "Loading Maps" Screen for 10 minutes.

Then another Update screen appears. Press Install again and watch is stuck again in the "Loading Maps Screen"

Hi, could you please be more specific? The same happened to me - after upgrade all sensors stopped working (heart rate, steps, even the display does not turn the light on after the hand moves...). Charged to 90% and when searching for updates on the watch it tells me "not enough power to turn on the wifi" so I am pretty clueless. Thanks for any help.

Coty you may want to check out some of the existing discussions on this forum, such as: Forerunner 955 keeps trying to update, Forerunner 955 keeps trying to update vol.2 .No Sleep Recorded along with several others on the same topic. Unfortunately, it seems Garmin has not yet publicly acknowledged the issue, so I wouldn’t recommend waiting for an official fix. Your best bet might be to contact Garmin support directly and request a replacement device.
