Enduro 2 is frozen/stuck (bricked) on the "Enduro 2" startup screen.

Enduro 2 is frozen on the "Enduro 2" startup screen.

Soft reset (holding down light button) doesn't work.

Can't get it to give me hard reset (light + lap button) option as doesn't seem to be able to get that far on starting.

Plugged it into computer overnight with Garmin Express open but can't find my watch (as I guess it's not starting up far enough).

Every now and then a button will make a beep if press them enough, and sometimes the HR sensor will flash green.

Watch screen will blink off then on again.

On a couple of occasions I have managed to get the light to come on but will auto shut off.

I'm signed up for beta testing.

Any ideas????
