ROG 5 tencent version / unable to unlock bootloader

[nersih_rashyd]

Model Name: ASUS_I005DA
Firmware Version: WW_18.0830.21011.75
Rooted or not: NO
Frequency of Occurrence: tried 5 times with no luck
APP Name & APP Version (If your issue relates to the app): Device unlock App
========================================
I want to root my phone, but I cannot download the bootloader unlock application from my ROG phone, so I downloaded the same app via PC and transfered to phone. After running the APP the bootloader doesn't unlock.
