This package contains the files needed for installing the 4.72 firmware for Sony Play Station 4 systems.
If it has been installed, updating (overwrite-installing) may fix problems, add new functions, or expand existing ones.
Interrupting the installation can cause your system to be damaged.
- You might not be able to use some applications or content without first updating the system software.
So it's not exactly a PS5, but it's a significant upgrade over the existing PS4.
