When you pulled out the battery was the phone powered on?

If you are able to access the settings, you will want to perform a Factory Data Reset.

1. From the main screen, select MENU.

2. Select Settings & Tools.

3. Select Phone Settings.

4. Select Security.

5. Enter the security code then select OK.

6. Default is the last 4 digits of the phone number.

7. Select Restore Phone.

8. Select Yes.

9. Press OK.

10. Enter the security code then select OK.

          -Default is the last 4 digits of the phone number.

Check to see if you are still covered in warranty. If not, you will need to upgrade.
