First, welcome to the forums. It is most likely a JVM error. I assume it is a 507, which typically indicates that there is no operating system on the device. If you don't have desktop manager get it. You will need it to reload the OS. Get the OS (and DM if you don't have it) here: https://www.blackberry.com/Downloads...93E4F3BB068C22
Install the latest version of the OS and connect your device to your PC and start up DM, run application loader, and all should be well.
