Xperia S forgotten PIN on screen unlock.
So today I somehow forgot my PIN on screen unlock and don't know how to "reset" PIN on screen unlock. Umm,if it is possible without FACTORY RESET because I have really important job stuff on my device and since it hasn't got option for SD it will erase all. Please help me guys... It is even rooted Xperia S.PLEASE GUYS HELP ME!!! P.S - I have no GOOGLE PLAY login,only numbers and emergency call so there is no other way.. Even though I tried 205 times today and still no GOOGLE VERIFICATION.
