Boot loader won't unlock LG G4 H811

Boot loader won't unlock LG G4 H811
I have a LG G4 H811 (firmware version H81120o)
I want to unblock the bootloader but all attempts did not help
when you try to unlock through the ADB, after the second command line
the following text appears on the phone:
--------------------------------------------------------------
* Welcome to Fastboot Mob for bootloader unlock:

* Quik Guidance
1) How to ulock: fastboot oem unlock
2) Check bootloader is unlocked: fastboot getvar unlocked

* HOW TO exitfastboot mode
1) Press the Power button for 10 secs to turn off the device
2) Use "fastboot reboot" command if the fastboot is available
----------------------------------------------------------------
After the appearance of such text, the phone freezes and does not respond to any commands
I've tried all the ways that you can find on "YouTube" but they do not help
help me please
sorry for the incorrect text, I use Google translator
thanks to everyone

This is 2 months late, but if you're still looking for a possible solution, this is what I did:

1.) Download the tools you need here: https://developer.android.com/studio/releases/platform-tools/ and extract
2.) Install LG United Mobile Drivers from here: https://lg-united-mobile-driver.en.lo4d.com/. I recommend uninstalling previously installed LG G4 drivers from Device Manager and then reinstall from that page. You may need to install additional drivers once you connect your G4 to your computer.
3.) In Developer Options, make sure you have "Enable OEM unlock" checked and "USB Debugging"
4.) Open a command prompt in the tools directory (hold shift, right-click inside the folder, and click "open command prompt here." If you've authorized your device to be recognized by your computer (two prompts should popup: one to allow USB connection and another to allow USB debugging), your device should be listed if you enter the command "adb devices"
5. Enter "adb reboot bootloader"
6. Once the phone has rebooted into the bootloader, you should be at the stage where you get the text on your phone, as you described. Enter "fastboot oem unlock"
7. Check if you've unlocked the bootloader: "fastboot getvar unlocked"
8. If successful, you can then go on to flash TWRP onto the recovery partition and root your phone by flashing Magisk from there.

    To regain root, simply use
    Code:
    fastboot boot
    and drag and drop the TWRP file and press enter, and install root of your choice.
