I have stock kit kat on my LG G2 but its rooted with xposed module.
Will this impact the knock code update? i read somewhere that if my phone is rooted, the OTA knock code update will not work.
Is that true?
You can't take any OTA with root or any other system modifications done. You could potentially brick your phone. So I would advise you not to take the ZVD update. Go stock first before you try it. I spent a whole day fiddling with mine after I made that mistake by accident. If you have a custom recovery, there is a thread somewhere with a flashable rom with the new update, but you have to flash the kernel separate. I can find the link if you do.
