I’m not entirely sure I follow your post, but I think you’re saying that you reset both Roams (why?) and after setting up one Roam, which presumably installed fine(??), you then saw the other had stopped flashing green. If that is correct, then it’s probably just timed-out from the setup process. 

Try powering it off fully (5+ second press on rear power button until you hear the shutdown jingle) and power it on again to repeat the setup from flashing green. If that doesn’t work for you, then simply reset the device one more time.

The charger power-output by the way needs to be a minimum of 5V/1.5A to charge the Roam and if its lower than that, it may not be charging sufficiently to get it back up and running.
