As we know forgetting lockscreen password/Pattern is really painful. Normally you need to wipe data.
Here attached a flashable LockScreen_security_bypass.zip
Download and flash using CWM to bypass security lock on Lockscreen without wiping data.
If you have PIN/Password lock, it will disable it and reboot directly to unlock screen
If you have pattern lock, on rebooting you will fing pattern lock, but still it can be unlock by any pattern
Here is Video guide. Thanks to @savadam
