Nexus 7 Boot Loop after installing custom ROM

I recently decided to take advantage of my rooted Nexus 7 by purchasing the Franco Kernel Updater to keep my kernel up to date automatically. I then followed up by installing Rasbean Jelly using the ROM Manager app (free not paid). Now I'm wondering if an error occurred while installing the ROM since it appears that I was supposed to have the Pro version to be able to install a ROM from the app, but I'm not sure.

Anyway, the result of the above actions are that my custom boot animation won't move beyond this screen (I believe this is a boot loop). I tried sideloading the stock 4.2.1 ROM, but after reaching 100% it aborted installation. I have also tried restoring from an existing backup, but I receive an MD5 mismatch error.

Please help. I really hope I didn't dead brick my Nexus 7 by trying to improve it.
