When I plug my BlackBerry to be charged or in the computer, the LED will light for about 20 seconds, and turn off; then the screen lights up with a battery icon in the middle with the lightning bolt icon in it. Screen won't power up unless I try to install the OS back onto the BlackBerry, and when that is tried, the computer says it won't detect my BB (although it detects the Unknown Pin option in the AppLoader).
