Default "EXPAND" Not a command to do kdz for lg p769

Hi to all

So yes I have bricked and will not go past Lg logo because it says Security error on my LG Optimus L9
the thing is I have found the solution but now when I try using a kdz to bin file it wont let me because the following thing come up

So any have an idea of how this will not work I am using W8 by the way and if this a computer problem then sorry for posting it hear

and as well its more easier to recover a dam Samsung than a ******* Lg

Thank you for your time
