[Q]Unlocking bootloader - LG Optimus L9 P760, P765, P768, P769

I was trying to unlock my bootloader, but always i tried it reboots only in simple way, no in fastboot.
I tried all of methods, but unsuccesful.
I have lg p760 maybe Romanian version.v20d , android 4.1.2
I tried flashing european version, maybe i have problem with unlock cuz of romanian version.
I tried with offline kdv but i get this error

Yes, i installed it correctly
I can flash with kdz only v10xx firmwares. For some reason with v20x firmwares i cant succed. But its not problem, from v10a with clockworkmod i installed v20h rooted. My real problem is that i can unlock my bootloader.

Maybe problem is that i cant install correctly the driver.

I've only translated the tutorial and make it more noob friendly, but it was almost same. Can you try it at another PC with windows 7?

No, i dont have another pc. I try to translate what error shows up when i try to install the driver
windows found driver for the deivce, but a problem occured during the instalation.
The inf-file from external manufacturer, doesnt include digital signature, or something like this.
Sorry for my bad english.
