Flashable PIN Remover for CM11 topic

Hi guys I am having a strange problem.

After a long time I have restored the CM11 bkp. Since I used PIN lock that time of backup when I booted the phone it is asking me for the PIN. Since it is quite old bkp I cant remember the pin.
So can someone can make a flashble zip file which can disable the PIN.
