Certain Hardware keys not working

[Guest Silverdoller]

Hi all,

I soft resetted my phone because of programs hanging and after i soft resetted,

The lock key, W&L and the front shortcut hardware buttons dont work anymore

The phone answer keys and vol rocker still works though

I am sure its not hardware problems because from the lcd test function i can still use the phone front shortcut buttons

and also when the phone is in sleep mode i can turn it back on with the lock button

However i cannot turn the phone back into sleep mode when i press the lock button and the main menu/task switcher doesnt come out when i press the front shortcut button

I am also stuck in the work mode because the W&L button doesnt bring me back to Life mode as well.

Can somebody help me on this? Thanks a bunch
