Blackberry App Loader Will Not Connect

So.. I wiped my 7750 trying to start clean since it's a used device.


Now it's on JVM Error 505, usually no big deal. Just reload software with the app loader.


That's not working.


It connects fine every time, and acts like its going fine until it connects with the boot loader. 


Every time without fail it loses the connection to the device immediately after it appears to connect to the boot loader?


Any ideas? I have tried a rewipe with: JL Commander, BBSAK, and the Blackberry Developer Kit to no avail.
