OK, I didnt think it was going to do it but it was worth a shot. Ok heres what you need to do. You need to download the lates OS for your device and install it on your pc. Get it here http://forums.crackberry.com/f52/new...evices-208149/
From that link I gave you follow 1 and 2. Dont need to do 3 yet.
So you have the OS and the Desktop manager installed.
Do that backup I suggested if you want to save your contacts.
Go ahead and do the jl_cmdr thing again but this time do 4. When its done you will have the 507 error on your screen meaning there is no os. Start the apploader and reinstall. The instructions with jl pretty much gets you where you need to be. Good luck.
