Default [Q] I've inherited an original (broken?) Nexus 7

Apologies if I'm asking anything blatantly obvious, I'm relatively new to all things Android..

The Nexus 7 I have won't boot it just displays the Google logo & an open padlock.
I've been advised to try the Nexus Root Toolkit & it's Soft-Bricked/Bootloop option.. unfortunately this doesn't work:

erasing 'boot'
FAILED (command write failed (Invalid argument))
finished. total time: 0.001s
erasing 'cache'...
erasing 'recovery'...
FAILED (command write failed (Invalid argument))
finished. total time: 0.001s
erasing 'system'
FAILED (command write failed (Invalid argument))
finished. total time: 0.001s
erasing 'userdata'
FAILED (command write failed (Invalid argument))
finished. total time: 0.001s

sending 'bootloader' (3911 KB)
FAILED (command write failed (Invalid argument))
finished. total time: 0.001s
rebooting into bootloader...
FAILED (command write failed (Unknown error))

archive does not contain 'boot.sig'
error: out of memory

Any help would be greatly appreciated

Thanks.

If the padlock is opened chances are there is a custom recovery see if u can boot into it. Hold volume up and down together and power

Nope, I can't do that.. it just starts the bootloader & I can't select anything when it's on
The bootloader screen info is as follows:

FASTBOOT MODE
PRODUCT NAME - grouper
BOOTLOADER VERSION - 3.34
LOCK STATE - Unlocked

you might be able to soft-boot it (that is, have it boot a custom recovery without actually flashing it to the eMMC chip) as in:

Code:
C:\blech> fastboot boot eg-custom-recovery-imagefile-of-your-choice-goes-here.img
and have a look using adb at the kernel boot messages from that custom recovery's boot log (once it has finished booting)

Code:
C:\blech> adb shell dmesg > dmesg_log.txt
my guess (because fastboot erases are failing) is that it might boot but will not recognize any valid partition tables - you will see messages to that effect in the kernel log.

If that's the case, there is nothing you can do to fix it.
