I successfully installed 4.5 on my wife's 8300. I followed the same procedure for my daughter's 8300....and now I have a steady 507 screen. I've searched and tried to repair, but no luck. I understand I have no OS on the BB. When I open App loader>connect bb it goes through the initial steps, but the 507 appears right before I click OK to install the OS.
What am I doing wrong.
Thanks in advance

try those step by step. keep in mind the second link may take up to 10-20 times before it will work.

What exactly should happen. This is the current state of my BB a white screen with a circle/slash and 507 underneath. Running the Jl cmder does not have any affect on the BB. Is there a next step I need to do?
Thanks again
