From what I remember, update 2005.04 is not PS4. Just the same code base. Personally, I would remove PS3 and 2005.04 and install PS4 using the PS4 install media. It's one way to avoid the upgrade gremlins.

For some reason some servers "revert back" to PS3. If we set it back to PS4 as the version and reboot it goes back? But this does not seem to stick all the time. Has anyone else run into this? Any idea of fix? W2k3 Regards, Doug Stratton, Shared Service BC Service Desk Email: 77000@xxxxxxxxx Service Desk Tel: (250)387-7000
