Help!!!! Soft bricked nexus 7(2012) wifi - Nexus 7 Q&A, Help & Troubleshooting

Please help..... this is my daughters tablet and its soft bricked.
Im unable to boot it at all....... it just freezes on the `Google` image and the green recovery image is also present on the same page. If i boot it into recovery and try and boot from there it just keeps saying `booting failed`

Have also tried to flash the bog standard Advent software and get the same error.
What could be causing this? Would it be connected to the SD card as it did fail a while ago?
Please help, I sold this to some one and he has sent it back due to this problem and im trying to fix it... might have to refund (
Its not the SD card, have changed it and works fine.....
Any other ideas?
No idea what has changed but have tried a few more times and it has flashed ok... phew!

Go to the android development section and download Wug's toolkit. There is an option there to unbrick your device.
I get this:

Problem with updating cwm recovery

Hey guys,
at the moment I'm trying to go back to Stock rom. But I think my recovery is not working well, because I'm not able to do a nandroid backup or even a restore from an old backup fails every time. So I decided to renew my recovery by following this instruction http://forum.xda-developers.com/showthread.php?t=1831161&highlight=cwm
Unfortunately I´m stucking at this point where I enter this.

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I always get the message "permission denied"
USB debugging is on, I tried several usb ports and corts. Still don´t know how to move on. Hope you can help me.
Ok I solved the problem. I don`t know how, but adb root acess was disabled.

Pic doesn't work.
I suggest downloading and installing the stock firmware via ODIN.
If it still doesn't boot after that, it may be hardware failure.
