Your problem is not from rooting. You may have inadvertently messed up something in your system partition. Try to lg flash tool back to stock.

⬆⬆⬆⬆ Rooting cannot break knock on. I would try
1. Make sure it's on and toggle it either way
2. Factory reset after making a LG backup and dragging that file over to your computer. Then reset and drag the file back To the LGbackup folder on your phone. Restore from backup and the whole process shouldn't take more than 5min and you're phone will be exactly the way you had it setup still.

Did you by chance downgrade from 4.4 at some point?

Yeah def try these first before restoring back to stock. Also some xposed modules can break features

You need to update your touch firmware in the hidden service menu. I could provide you with how to get there if you had mentioned what variant of the flex you have

I'd LOVE to know how to fix this issue on AT&T 950 variant. That's the only thing keeping me from flashing back to 4.2.2 so I can install custom recovery. If you know how to fix it when I downgrade from KK to JB I'd be forever grateful.

Like justinwidebody suggested dial 3845#*959# then click "Settings" then "Update Touch Firmware"
or in Geners case I think you have to dial 3845#*950#

Hey Justin. I believe you have the sprint variant correct? If you do, what is the dialer code for it to fix knock on after downgrading?
