Outside of a brute-force crack, it is not possible to derive the clear text of the password from the encrypted value. There should be a "reset to factory settings" option, which will allow you to reset the unlock code. Unfortunately, that would end up losing all data and other settings on the device as well. In any case, unless there are tools out there to reset the unlock code without losing everything else, that is all you will be able to do, in all practicality.
