Thanks for your answer,
Is Shipped ROM as same as Stock ROM ?
Because, I did reinstall Stock ROM + Upgrade from BellCanada, and didn't work.

Do I have to relock the phone ? Could it make a difference ?
****UPDATE****
Even with installing Stock ROM + Relock , it doesn't not work ..
Now, when I open the camera program, I have the message : Device.exe problem ... .and still black screen.

Have another idea ?

Thanks
