After some research, I have found that a Device reset may be what you need for you to clear that error msg.

You can either pull the battery or restore to factory spec.

Rest your device.

1.
Find " Security Wipe"
Slide your finger down the display starting from the top edge of your mobile phone.
Press Settings.
Press Security and Privacy.
Press Security Wipe.
2.
Restore the factory default settings
Press the text input field and key in blackberry
Press Delete Data.
Wait a moment while the factory default settings are restored.
Follow the instructions on the display to set up your mobile phone and prepare it for use.
