Exploited PS4 system allows you to install any PS4 PKG games or utility. But the recently released games require higher firmware. As long as we had PS4 jailbreak 5.05, we could play limited games. But now we have PS4 Jailbreak 6.72 which means we can play a lot of games. As you know due to 6.72 unstable jailbreak many people have stayed on previous jailbreak version and waiting for the stable release. You must have already heard the name of PS4 backport. Now it’s time to take advantage of PS4 backport.
PS4 backport allows you to backport PS4 games from 6.72 to 5.05 firmware. Previous jailbreak users can play higher firmware games on lower (5.05 exploited) firmware by backporting game PKGs. Until the stable jailbreak of 6.72 firmware is released, you can use this method to play high firmware required games. So, let’s get started.
How to Backport PS4 PKGs
