Please help me! Nexus 10 problem! topic

I was using the Cyanogenmod nightly for lollipop, and an update came out. I downloaded the update through Cyanogenmod's built in updater, and now my tablet is stuck in a bootloop. I can get to bootloader, but I cant do anything aside from "Start". The volume buttons do nothing. I tried using NRT with the drivers reinstalled according to the directions in the program, but my laptop won't recognize the device! What do I do? Do I just have a giant expensive brick now??

TLDR: I cant get into recovery, bootloader can only "start", it wont boot to home screen, and my laptop (Windows 8.1) won't pick it up.

PLEASE HELP! I RELY ON THIS TABLET FOR EVERYTHING!
