Default Knock on doesn't work ;(

Hi, so recently rooted my LG-F320L and knock on doesn't work anymore while knock off works... I've seen threads where u have to dial something like 3845*#802# or 3845*#800# and you go to hidden menu, but it doesn't work, maybe because it's Korean version..? Maybe I've done something wrong with this root: http://forum.xda-developers.com/show...9#post45692679
And also I've tried hard reset with menu button and volume down button and it doesn't work, just LG logo keeps reloading :/
I'm on my way installing CloudyG3 1.3 today, maybe things will change, hopefully
