Bootlooping after Flash to Stock

I was having trouble (bootlooping) with my Nexus 7 (2012, WiFi), and someone recommended this toolkit. Ran the "Flash Stock + Unroot" utility. Here's the cmd:

Booting up your freshly flashed stock device...

------------------------------------------------------------------

Wait for your device to finish booting up...

- It may appear to be boot looping; just wait...

- It could take 5-10 minutes; please be patient...

When its finally booted back up, please remember

to re-enable USB debugging if you plan on using

the toolkit to perform other operations.

NOTE: If this process was too quick and your device

is still in bootloader mode, then flashing stock may

have failed or been incomplete. Simply check the

log above: if you notice it skipped steps because it

didn't meet certain requirements, like the bootloader

or baseband version, then consider enabling 'Force Flash'

mode in the toolkits options menu and trying the

'Flash Stock + Unroot' processs again. Cheers.

Press any key to exit...

It's been stuck on the neon nexus "X" screen for at least an hour. I haven't touched it since the utility ran. Any help would be greatly appreciated!
