security - "Account unlock" when not connected to internet?

I have a Samsung Galaxy Y mobile phone. I see this screen when I press "Forgot Password" in the pattern lock screen that comes by default with the phone:

My Question is: How would my account be unlocked when (i) "Wifi" is turned off and (ii) "Packet Data" is disabled?

Answer

1. 
   

   Search and download Unlocker or Screen Lock Bypass app from internet (which are no longer available in Play Store).

   
   


2. 
   

   Push it to the system from recovery (with update.zip).

   
   


3. 
   

   Start the system.
