    Lumin D2 stuck at circle

    Just bought the Lumin D2 yesterday and last night was playing fine. This morning I turned it on, it shows the circle on display. Can't figure out what happened. I tried hard reset by using a pin from behind , reset it a few times, still the same thing. If I remove the network cable, it will show network error. But as soon I as I plug the cable in , it shows the circle. (see attached pic). Did I get a defective unit?
    My Lumin app won't detect this unit as well.

    This post is for a U1 that had similar problems. Perhaps it will help:

    Keep getting Network Error message on front panel of U1

    You might try doing a factory reset using the Lumen app on your phone or tablet. You can also power cycle by unplugging the power cord for a few minutes. Just some things to try. It may or may not solve your problem. Good luck.

    Turn the Lumin off with the back switch and shut the network down back to the router and re-boot from the router forward one piece at a time. No need to turn the Lumin off when not playing it just let it go to sleep at the most. During this process turn the control device off too.

    A circle display is normal expected behavior after factory reset or clearing the current playlist. Please use Lumin app to add some music to the D2 and start playing.
