This means you can't unlock your boot loader

Dial this
*#*#7378423#*#*

And then check if it says boot loader unlock: yes

For this go to ⬇

Go to service info and then customization

No sorry you cannot unlock it
There isn't anything you can do, sorry. On the bright side you at least won't flash anything and brick your phone. I bootlopped my phone while Unlocking Bootloader :P
