Default LGG2 Flash stock 4.4 KK with CWM + xdabbeb cam mod

Newbie looking for help :s

I have a lg g2(d802) with 4.2.2 JB i and tried xdabbeb camera mod to get 120 fps record, but if i have understood correct that only works with 4.4.2 stock KitKat.

Should there be any problems in flashing my g2 with cwm and the new "4.4.2 D802_Stock_KK.Zip" and be able to record 120 fps?

Thanks!
