dead blackberry after trying to remove IT policy

I have an 8310 and after doing all the steps found here to remove IT policy, my blackberry had an error message with 507 on it. I can't do anything with the blackberry, this is the only thing on the screen.

What is my next step? I have tried doing recovery with the Desktop Manager but it won't give me the option to recover.

Please help, I am new at this and should not have taken on such a task with my little knowledge.

I do not have discs to go with my blackberry.

Thank you,
Kathie

A 507 error doesn't mean your BB is dead. Error 507 simply means there is no OS installed on the device.

Why not? You can download the desktop manager here.

Good Luck!
