[VZW] HiddenMenu
Read the entire 7 page thread, and follow directions.
System app this should be with terminal instructions.
This did fix my knock on problem.

I flashed back to stock twice using the ZVC tot and knock on wouldn't work either time. Thankfully I got the knock code update to ZVD and that did fix it.

Really? The update worked fine for me[emoji4], I love the Knock Code feature.[emoji4]I had the opposite problem, ZVC was all fine and ZVD messed up the knock on feature,

Knock on won't work when you have knock code lock screen.

This doesn't work for me. I've replaced the HiddenMenu.apk properly, changed permissions, and rebooted. Once into the menu either by terminal or dialer code, there is no HW Device Test option to choose. It's giving me the same hidden menu that Sprint already has. Again, yes, I replaced the apk properly.
Stock rooted ZVC
To Clarify even more:
If you tap your "Knock On Code" while the screen is off, it will wake up and unlock to desktop. The double tap to wake is not active while you have the knock code active.
just sharing my experience: i updated to zvd, back to zvc, to cm11, back to zv7 and ota'd all the way back to zvd and my knock on still worked, it is now broken after i flashed the white lines fix after flashing the tmobile stock rom by novembre5. tried every fix in this thread and still no fix. knock off works flawlessly. im sure if i went back to zv7 and took all the ota's again ittl work but i need this rom to use my tmobile service.
I'm on a US Sprint LG-G2 and folllowing beezar's advise was able to get into the proper hidden menu. I went ahead and updated the Touch Firmware but still no go. 2 questions:
1. What is the correct firmware version that will fix the knock on issue?
2. Does the proximity sensor have any effect on knock-on? I just recently replaced my screen and think I may have damaged the proximity sensor. When I use one of the proximity sensor tests it never seems to work. Stays at 0cm.
Thanks for any help!
Just noticed that yesterday. I have stock zvc rooted. It did work shortly after i ran .tot. I just dont know why or when it stopped working. Knock off works just fine.
Apparently toggling it on and off, and recalibrating the screen in settings fixes the issue for many.
