Hi there,
Looks like you should try to Hard Reset it.
This is done by having your HTC Diamond turned off first.
Then, hold the
VOLUME UP and DOWN buttons at the same time and briefly press the
POWER BUTTON.
Now keep holding down the
VOLUME UP and DOWN buttons until you see a screen
At soon as you see this screen, you should release the
VOLUME UP and DOWN buttons.
Now press the
VOLUME UP button to complete the hard reset.
Now this will completely format your HTC Touch Diamond as if it was turned on for the first time from the box. Everything once previously on the phone will be deleted including messages, contacts, music and the like.
Hope I have been of assistance to you,
Cheers :)
