I recently wiped my blackberry becuase it was acting weird. Now I have a white screen that says 507. When I connect it and start up DM, it says Disconnected but I can open App. Loader and it detects it. But my problem is that I'm trying to put all the programming back onto it?

How would I do that?

First you need to reload your operating system!

Then you can put your apps back on.

Check in the Blackberryfaq there are complete instructions on how to do this
