phone bricked?

[Black Gas]

I used setup moto4lin as instructed here, http://mac.themotoguide.com/index.php

and it connected to the phone (v3r). It was working. Then, I hit disconnect, unplugged the phone. Now the screens are black, and nothing works.

When I plug in the usb, it still beeps.

I didn't do anything else, just plugged it in and connected it, now its dead.

Help!

EDIT: Never mind, removed the battery and reinstalled it, now it works!
