How do I over ride the phone lock on a HTC Chacha?

From here :

"Please note that all data will be deleted from the HTC Chacha as a result of this procedure. This process may or may not delete data stored on the microSD card. We recommend backing up all of your personal data before proceeding.

First, try this:

From the main home screen, tap menu

Tap Settings, then Privacy

Tap Factory data reset

Tap Reset phone

Enter your password if required, then tap Erase everything to confirm

If that doesn't work, or if your phone is frozen:

Turn the power off. If your HTC Chacha is frozen, pull the battery out and reinsert it

Hold the Volume Down button

Press and hold the Power button until the device turns on

You are now presented with a menu that allows for Fastbook, Recovery, Clear Storage, and Simlock

Select Clear Storage by pressing the Volume Down button

Press and release the Power button

Now simply confirm your decision: Volume Up for YES and Volume Down for NO
