A limited but working jailbreak for PlayStation 5 hardware has reportedly been released, potentially allowing players to install unsigned or unofficial software.
The news was reported on Twitter by modder Lance McDonald, who had already made a name for himself by releasing an unofficial patch that made Bloodborne run at 60fps on PS4.
Although McDonald doesn’t appear to have discovered the PS5 jailbreak himself, he does show some footage of it in action.
In addition to showing that the jailbreak grants him access to a debug menu, it also shows that it allows him to install a PS4 PKG file (i.e. a game savegame), proving this by installing the now deleted PT demo.

At this point, the jailbreak would be extremely limited – it would only work on PS5 consoles with firmware version 4.03, which was released in October 2021 and replaced by version 4.50 in December 2021.
According to the creator of the exploit, it may be possible to jailbreak PS5 consoles with firmware versions earlier than 4.03, but later firmware versions will not work at this time.
Even if a player has a console with firmware 4.03, the exploit’s creator warns that it will still only work about 30% of the time, usually requiring multiple attempts to run.
Even once the player does that, they will be strictly limited in what they can do at that point, it is claimed. While the exploit is supposed to give read/write access, it does not give execute access. This means that while McDonald’s has allegedly been able to install the PT teaser on his PS5, he won’t be able to run it yet.
Given the limitations of the alleged exploit and the fact that it only works on a specific one-year-old firmware version, it will currently likely only be useful for other hackers curious to see how it works and if they can use it as a starting point for something more effective.
It will, however, be a concern for Sony to see some progress, albeit minor, on attempts to bypass the PS5’s security.
