help needed badly with u700 touch sensitive buttons!
 

I have made a big mistake!! Was looking through the service menu on the u700 by pressing *#0523# and have somehow managed to disable the touch sensitive buttons and they do not work at all and neither does the centre wheel and button so i can't do anything! The keypad works still but nothing else! Any ideas?

put phone on without sim card - and type - *2767*3855#
phone will reset - reboot - and back to factory settings
