Nexus 7, Cant unlock bootloader with command prompt, PLEASE HELP!

[KennyFabian]

HELLO GUYS! I HOPE YOU HELP ME WITH MY PROBLEM.

A few days ago my tablet ran out of battery, so when I connect it to the wall charger, and a couple of hours passed, i turned it on again, it was stuck on the GOOGLE logo and no further that, the GOOGLE logo with the same options of the fastboot mode.

I did some research and found this to be a known issue, so I have to unlock my bootloader and flash a new image to my nexus 7.

I can get access to FASTBOOT MODE perfectly. And my USB fastboot drivers are installed correctly. When i put the command

"fastboot devices"

It works perfectly founding my device as well showing me its serial number.

My problem is that I cant unlock my bootloader, and i judt dont know why.

This is the command to unlock the bootloader I tried:

"fastboot oem unlock"

When i press enter, suddenly pops a window in my tablet asking me if Im sure to unlocking bootloader and avoid warranty. When i press YES.

This is the result:

(bootloader) erasing userdata...
(bootloader) erasing userdata done
(bootloader) erasing cache...
(bootloader) erasing cache done
(bootloader) unlocking...
FAILED (remote: (Unknown error code))

On my device in fastboot mode, it just shows at the top "unlocking now......" and nothing else happens.

Does anyone have a clue what might be wrong? :-\

Is it the END for me?

Try wugs toolkit was your USBdebugging set to on before this issue? I suppose it was to get that far.
