Asus 5Z - can't unlock bootloader using Asus tool

[Jazornowsky]

Hi,
im using 5Z - ZS620KL with latest available update. I tried restoring to factory state, connecting to wifi/lte. Nothing works and I just can't unlock bootloader using Asus tool. It just throws error that it failed.
Any suggestions?

Hello Jazornowsky,
This model has stopped maintaining the Unlock Device App.
We apologize for any inconvenience caused.
Thank you for supporting ASUS products.

After few days of trials it finaly unlocked. It's weird that official app behaves like that. I undestand that it's EOF, but at least give some apriopriate message about status in app. Not generic "failed" message.
