Possibly Soft-Bricked Moto X with flashing recovery screen

Hopefully you guys can help me with my problem. Recently, I downloaded the new Marshmallow app drawer from Android Pit's "Here's how to get Android Marshmallow's new app drawer on Lollipop". It was successfully installed and seemed to be working fine. However, Google Now gave me a message saying that it was not connected to the microphone and that I should reboot my device. Thinking that the actual reboot key combo was power and volume down, I did this and this brought me to the fastboot page. I selected and entered the power up normally option on the top, which the booted my phone to a completely black screen, from which only the "power off" option would show if I held the power button down. I was confused and concluded that the app drawer somehow soft bricked my phone. After reading up on the web, I went into recovery in the fastboot screen, then selected clear cache. Two lines of orange text appeared at the bottom saying that the cache clear was starting and that it was finishing. I hit the power button, tried to boot my phone up, then, recieving another black screen, brought back up the fastboot menu and tried to enter the recovery screen again so that I could factory reset my device. The recovery screen gave me messages about how it could not load the cache, and since then has been flashing on a set interval on my screen (going black, showing the broken Android with "no command" then going black again).

Any ideas on what I can do to fix this problem?

note: (I have not rooted my phone)
