Re: blackberry desktop manager cannot comunite to detect this device


I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, attempt to undo whatever you most recently did.


Otherwise, this KB might be helpful:

  • KB30100 "JVM 200" appears on the BlackBerry smartphone

Good luck and let us know!
