Question: On the bootloader screen, somewhere on the lower left hand side, it should display the BOOTLOADER LOCK STATE... On my older N7, it says: LOCK STATE - UNLOCKED.

Further, when your N7 boots, do you see a white unlocked padlock symbol, at the bottom of the screen... underneath the Google Logo?

That means the bootloader is definately locked...which means you can't fastboot flash a factory stock image.

As I've alluded to previously, the only way to proceed, is by successfully running the command...

Code:
fastboot oem unlock
...and confirming the request at the Nexus 7 end with the Power Button.

If this command continually fails, then you likely have a hardware problem... probably a bad eMMC chip.

The only thing I can suggest, is you try every combination of USB ports/USB cables... every permutation you can think of. Even try another PC, if you have access to one.

But whatever you do, the above fastboot command MUST SUCCEED if you have any hope of fastboot flashing anything.

As you've probably gathered, you'll know if it's worked by looking at the lock state in the bootloader screen, and by the presence of the unlocked padlock symbol upon boot.

I wish I could help you more... but I have to go out in the next 20 minutes... but I'll be back online in around 4 hrs.

Best of luck.

Rgrds,
Ged.
