Can't unlock bootloader

I am using Moto g5s plus and I unlocked the bootloader using unlocking key. But after some time i relocked the bootloader using the cmd " fastboot oem lock". But now I want to unlock the bootloader again but it showing the error msg " invalid boot state" . I used many methods like "unlocking key" , cmd - "fastboot flashing unlock" , fastboot oem unlock" but nothing works. Please help me to unlock the bootloader. Thanks in advance.

My RM3 was already bootloader unlocked,

Your bootloader is still unlocked. It just means everytime you wana flash something through ADB you have to send first the following code:
Code:

Question How to UNLOCK BOOTLOADER UNOFFICIALLY ?

Greetings!
As far as I know ASUS does not have a physical bootloader unlock counter like Samsung smartphones with their KNOX. This means that ASUS gets information about the unlocked bootloader via the internet when using their official unlock bootloader app. That is, ASUS gets the IMEI or S/N of the smartphone and puts it on their blacklist.
Is there any way to unlock the bootloader unofficially?
I really want to be able to get the bootloader back to its locked state and start getting and installing updates from my smartphone without using a PC as it was before the bootloader manipulation.
I tried these adb commands, but they don't work.
fastboot oem unlock
fastboot oem unlock confirm
fastboot oem asus-go
fastboot oem asus-go confirm
fastboot oem get_unlock_key
fastboot flashing unlock
fastboot oem asus-unlock working but i got error Verify unlock token fail.
