Knock on not working after "Device test" in hidden menu [D802]

It's been always like that.
Whenever I press "Device test" in the hidden menu, the device gets semi-stuck (not really.. because when I press the home button it exits) and I lose my knock on (both when screen on and off).
I forgot about it and pressed on it again.
My last nandroid backup is pretty old...

What should I try?
Ofc I tried the hidden menu touch firmware upgrade.. Didn't work.

Knock code enabling / disabling with Tasker

I'm sure the answer is going to be stupidly obvious, but I cannot for the life of me get Tasker to disable the lockscreen (knock code) via a task.

The end goal is simply for me to enable the knock code when I am not connected to my HOME Wi-Fi, and disable it when I am connected to it at home. I've set it up similar to other phones I've used but I simply can't get it to function on the G4 (ever owned LG before so it could be a specific way to do it with them and knock codes).

Tasker is set as a phone administrator. Can anyone either show what profiles/scripts they have that DO work, or walk me through the process?
