How:

1. Blackberry Battery Disconnect.

2. Wait about 30 seconds and then plug it in again (same as Hard Reset)

3. Once the notification light turns red immediately press the back / exit



4. Continue to hold the back / exit until the boot process is complete (until no logo)

5. If successful it will be no notification on the home screen like this


6. Just hit ok

7. Congratulations you've made it into "Safe Mode'' men immediately delete / uninstall applications that problematic.

8. To exit safe mode, remove the battery and let it run normally (quick pull plain)

hope that helps....
