507 means there is no OS on the device. Use the sticky thread at the top of the 9000 forum to reload the OS.

Go here and look at the top. >> General 9000 Series Discussion - Bold - BlackBerryForums.com : Your Number One BlackBerry Community

There are 3 threads that begin with the word "Attention". Those are known as sticky threads. The first 2 are instructions for different versions of OS. Pick which ever one you like and begin reading. I would suggest you read it all a couple times before acting if you are new to this.
