As we know forgetting lockscreen password/Pattern is really painful. Normally you need to wipe data.
Here is a flashable LockScreen_security_bypass.zip
Download and flash using CWM to bypass security lock on Lockscreen without wiping data. I have wrote script and tested on Note2 but should work on many other device too.
I have searched at various sites (including this one) and have not found a lockscreen mod for the lg g2. I did find a flashable zip for the Nexus 5 but that's about it.
I just rooted and one of my reasons for rooting was to change the lockscreen. I'm not happy with the locker apps on the play store and the lockscreen tweaks you can do through Xposed aren't substantial enough.
