[Help Please] Unlocking my bootloader in Marshmallow. (ZE550KL)

Hello, i have ZE550KL and i need to unlock my devices bootloader.

I know how to unlock bootloader in my phone but in the Zenfone 2 Laser if you are in Marshmallow it says "Unlock Device App stopped".

There isnt problem in Lollipop, if you use "Unlock Device App" it succesfully unlocks bootloader.

But i want to unlock bootloader in Marshmallow, but how?

Thanks. Greetings from Turkey.
