So far the note says that there are two methods to do it and both I have tried and it works.!
This tutorial is for Asus Zenfone Go ZC500TG/Z00VD users only. On the web site I want to share the batch auto tool that I have created. So, without wasting your time, lets go to the tutorial how to unlock your  bootloader..

The first thing to keep in mind is this tutorial is only for stock ROM firmware V36 / V25 and below.
If for stock ROM firmware V47 and above is impossible because it has no option to enable OEM unlocking.. So, it's easier if you are in stock v36 firmware stockrom.So, the first step you should do is to download the file below first.

How to run this tool?
Download and extract at your PC Desktop/Laptop. At your smartphone, go to phone setting and scroll down, search About phone option and under Build number try tapping 7 to 10 times for enabling Development options. Try to back again, this time we go to Development options. Under OEM unlocking  and under USB debugging, please enable! Open AutoBootloderTool.exe by double-clicking your mouse and then plug your USB cable into the phone and follow the instructions as stated.

Second method :-

This is a second method to unlock your bootloader, as many have not been able to use the available way there before. After it is identified that this device has 2 different bootloader secure, so I assume that this way can work and it is true. First you need to download 3 files and 1 tool and this file can be saved for emergency,  if your phone is in BOOTLOOP or DEAD PHONE.
