It probably does, but your KG status is likely PRENORMAL.
OEM UNLOCK needs to be enabled and then you need to boot directly into TWRP after the first time you flashed it and flash the RMM V3 bypass otherwise you will get KG locked again at next boot.

I'm not sure if any of this is included in any of the patches in the OP.

Multidisabler includes all of it.

Second post updated with further instructions , hoping this helps everyone understand the differences.
Reverted to old twrp build, more testing needed.

Yes. Bootloader is properly unlocked. Magisk works.

Bootloops on gsi are not related to twrp. Check with GSI dev.

PERFECT ! WORKS excellent now. I'm writing this small noob-friendly tutorial so people can follow, I hope it's fool proof.

Step 0: Prereq
Download all the zip files from the main page on your phone and put them in the external SD card.

How to enable developer
Goto settings -> About Phone -> Software Information -> Tap "build number" 5 times

Enable OEM unlocking
Go back to Settings -> Developer options -> Enable "Oem unlocking" (if you do not see this option OR its grayed out try to connect your phone to internet, or follow this https://forum.xda-developers.com/gal...s-100-t3823361)

Note: Enabling OEM unlock here does not mean your OEM is unlocked! This switch only allows you to unlock it..Also enable USB debugging.

Turn off your phone.

Next: hold UP + Power until you will see a green screen. It must say "Hold long up to OEM/bootloader unlock." Follow those steps, to unlock it.
Congrats, now your OEM is unlocked. Turn off your phone.

Install TWRP
Hold UP + Power again. In the screen select "wipe data (factory reset). Then select Turn off Phone (should be one of the lower options)

While phone is off, hold UP + DOWN volume and attach USB cable to your phone. It should go into download mode.

In Odin, put the TWRP_A40 image in AP
Un-tick Auto reboot in the options tab.

Remove usb cable.

Tricky part: hold 7 seconds down+power. As soon as screen goes black hold UP + power!
Now you should be in TWRP!!

Once inside TWRP
Flash all the zip files you downloaded to your SD card
Go back to main menu, select reboot -> Recovery. Then reboot normally.

Enjoy =) Android must now boot up normally.
