I was able to fix this by doing the following:
1) after downloading and unzipping the factory image from Google, you will see another zip file inside. Extract all those files into the same directory:
2) Create a new bat file called flash-it.bat, copy paste the following into that file:

4) use the volume up/down buttons untll you see "Recovery" , then press the power button
5)on the screen with the dead android press power button then volume up
6)Select "Wipe data/factory data reset"

8) celebrate! because it may take a while on the swirly colored balls screen.
