We had the technical writeup from CTurt, and the “confirmation” from bigboss. Today developer Zer0xFF put things together and released the source code for a proof of concept of the dlclose kernel exploit for the PS4. In other words, if you have a 1.76 PS4, you’re getting closer to a PS4 jailbreak, or to running Linux on your PS4.

This goes without saying, but this is not a CFW, it will not magically let you run pirated PS4 games. This is just one step closer for those of you with reasonable coding skills, who are trying to hack their PS4. You’ll need to be able to compile this and run it on your PS4. We give lots of details on how to do this in this article. That’s pretty much the same except you’ll use the dlclose exploit instead of the BadIRET one. (People have said that the dlclose exploit is cleaner and easier to handle).

From a scene perspective, it’s also good to see that more and more people are confirming the exploit and working on it.

Zer0xFF mentions that he got help from bigboss, but also from Twisted, whom you might remember for his Remote Play PC work. There’s more than a handful of people building on top off CTurt‘s work right now, which is promising.

Bigboss also hinted that he might release something for the sceen soon (ETA might be his birthday which is next week) , which I assume could be the exploit in a compiled way and potentially more user friendly.

If you’re a dev looking for help in building this, we also have a thread on /talk to get help on running the exploits on your PS4. Feel free to join.

Seems like these are good times to own a PS4 running firmware 1.76

Download the PS4 dlclose exploit

You can download Zer0xFF’s work on his github here. Keep in mind that this is the source code, it will be useless to you if you’re not a dev.

Also remember that a kernel exploit, especially in the early stages like this, is a dangerous tool: you could brick your PS4 if you handle this incorrectly. Understand that this is work in progress stuff from people who are willing to share their work with the scene in an open way. Don’t make them regret it!
