Vivosmart 5 Blinking or Solid Logo - Will not Start

My Vivosmart 5 will not start and the triangular logo keeps blinking and just displaying the logo.  I have tried pressing the button for up to a minute with and without power as suggested in these groups but it seems locked and will not start up.  The problem started earlier when I tried to connect it to Garmin Express to check for software updates.  Is there any other way to force it back to factory setting or reset the software?
