Hello Owjz,

Thanks for coming to the forums. What troubleshooting have you tried so we don't give you anything you already tried. If you haven't tried the

offline update, that would be your next troubleshooting. If that doesn't work your console may be in need of repair.

Thanks,

Brad

Have you done the full factory reset?
