So I thought it would be a great idea to try and root my brand new 2013 Nexus 7. After checking out a few tutorials online, I found one for mac, and downloaded the toolkit at:

I opened up the bootloader by holding down Power + Volume Down and opened the included script on my computer, which unlocked the device. I then attempted to restart it into recovery mode. I pressed Power + Volume Down on startup and opened up the bootloader. I then scrolled to Recovery Mode using the volume keys and pressed Power to select it and boot into recovery.
This is where everything went downhill.
I could open up the bootloader, but when I attempted to boot into recovery to load SuperSU onto my device, it got stuck on the Google logo with an unlocked padlock icon at the bottom of the screen. So I tried to boot normally, and it got stuck on the same screen.
All the forum posts I have come across so far to fix a bootloop all require the ability to boot into recovery mode or normally. I cannot find a guide that tells me how to relock and return to factory settings if I cannot boot at all.
Basically I need to unbrick my 2013 Nexus 7.
