The text menu will come on the screen. Then use volume keys to select and home button to select/enter.

Just go to phone settings in settings and reset to factory settings default. this will reset the phone to factory settings but will not clear any messages, contacts, pictures or data.. then you can go ahead and set a new password. 

the firmware might have got corrupted ...

give "restore factory settings"("reset") when you press "restore factory settings"("reset") you will be asked for the "security code"("password") provide that and after the task is complete restart your phone once ...

this will fix all the firmware problems ..

thank you
rate my solution

by resetting to factory settings, the security password is also reset.
Try this code: 00000000 (that's 8 zero's)
