Default Knock in doesnt work after Root and Custom Recovery

Hi guys. So I rooted my lg g2 D802 using towel root and flashed twrp using autorec. Then I flashed supersu in recovery. After rebooting, I noticed that my knock code doesnt work but knock off works. I turned knock code after to try knock on but it also doesn't work. Any ideas?

go to phone dialer and dial 3845#*802# a menu will pop up, go to settings>update touch firmware and wait about 15 seconds once done check if knock on works and don't touch anything else in hidden menu
