[LG Optimus L9 P760, P765, P768, P769] andras7008:
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
