Flashing Triangle

Hi

Hope you all are fine.

I’m here asking for your help, please.

My forerunner 255 today after I turn it on and press the start button started to show only the triangle without any other option.

I did what I saw in the help page of Garmin, like turning it off and press the start button and back bottton at the same time and then wait for the beeps. Everything went fine and Garmin watch reset and I did everything again like connection with cellphone.

Everything seems to be fine but when I press again the start button everything goes again to the same situation and the triangle flashing appears again without any other option.

Anyone with similar situation?

Thank again
