Unhappy [Q] Omnia 2 lock prob

Hello there guys,
got a quite annoying prob...i love my omnia 2 phone but accidentally my lil cousin entered several wrong screen passwords and locked it.
The prob is that when i try to enter the a1b2c3 , i can't due to my keyboard different than english language.
i tried to connect in a pc and backup some data but the phone doesn't seem yo be able to connect at all.
I hope there is a solution otherwise i am gonna loose tons of data
