hello,
today my garmin stucked on logo when i tried to upload custom watchface. As there is no topic about it. I tried hardreset like on Fenix3. It worked
Hard reset - method 2 (reset to factory settings) :
Power off the fenix 3 and wait for couple seconds
Press and release the Power button
Once the Garmin Logo appears Press and hold the Start and Back buttons.
When you hear the first beep (after ca. 3s) let the start button go
When you hear the second beep (couple seconds after first beep) let the back button go
The device will boot back up and you will be prompted to enter your profile information.
