To overcome the above problems you can boot the "Safe Mode in the Blackberry", ie a mode where Blackberry will live without load application as well as third-party themes.
Here's how to do the "Safe Mode on your Blackberry":
- Do a hard reset by disconnecting the battery then put it back.
- When the red LED indicator lights, press and hold the Escape key (Back Button to the right of the trackball or trackpad)
- Confirmation dialog will pop up a message, press OK to enter Safe Mode
- Text "Safe Mode" appears on the screen indicating BB Home Screen has been in safe mode.
- Uninstall program or theme that makes your Blackberry problematic (if not sure, uninstall the program / theme the last time you install)
To exit Safe mode Hard reset did back in the first step.
