This is the most important part of this guide. You cannot simply download a PKG file and install it on a brand-new PS5 straight out of the box.
To install PKG files, your PS5 must be "Jailbroken." Currently, the PS5 Jailbreak only works on specific, older firmware versions.
If your PS5 is updated to the latest version (which it likely is if you play online), you currently cannot install PKG game files.
