Default Boot loop after 4.4.2 update and Clockworkmod install

Stuck in a bootloop. Here's my story.

Updated to 4.4.2 earlier today.
Tried to root my Nexus 7 later after the update. Here's what I did:
  • rebooted into bootloader with adb (adb reboot-bootloader)
  • unlocked the bootloader with fastboot (fastboot oem unlock)
  • flashed clockworkmod using fastboot (this is the file i downloaded and flashed: -
  • rebooted into recovery
  • selected "install zip>choose zip from sdcard" (trying to install file that I had loaded onto the internal memory)

Here's where I ran into trouble. After selecting "choose zip" nothing happens, and a message shows up on botton of the screen that says "E: Can't mount /sdcard"

So I can't install anything from clockworkmod.
I rebooted into bootloader, tried to re-flash using fastboot - "device not found"
I tried to reboot the device into android - bootloop animation
I tried wiping data, cache, factory reset, dalvik chache, etc from recovery - still getting bootloop animation

Any ideas?

Ok, I wiped/deleted sdcard data from clockworkmod and I managed to get it to boot.

That's deadly but I still don't have root, which was the point of this in the first place. Anyone know where I went wrong?

Strange. I did pretty much the exact same procedure and it worked for me.

So, I flashed TWRP.
Tried installing SuperSu from there. This worked slightly better than Clockworkmod Recovery, it at least could read the internal storage, and allowed me to select the file. But I get the following error when I try to install it:

E: Unable to open zip file
Error flashing zip 'sdcard/Download/

Not sure what's happening here.... May have to do with the 4.4.2 update? Maybe I'll try flashing the 4.4.2 factory image and then retrying the above steps.

I also did pretty much the same. I had a new Nexus 7 2013. The very first thing I did was to update to 4.4.2 through OTA before I went to rooting procedures:

Unlock bootloader (data was wiped because of it)
Flash TWRP
Flash file through TWRP

Everything worked fine.
