A hacker/developer has showcased the ability to run homebrew applications and backups on PS4 firmware 4.55 via a new kernel exploit. Hacker Flat_z shared the video below in an interview with Imaginary Monster; the video demonstrates a basic homebrew application and an executable package file running a game via the backup method on firmware 4.55
This video shows a great deal of promise in terms of finally obtaining a full jailbreak for the PS4, something many users have been waiting for for a very long time. The claim made is that installation of custom and repacked PKG files on a retail PS4 via the XMB may finally be a possibility through this kernel exploit. Not only would this allow for homebrew for the PS4 to be developed, it would also allow for pirated games on the PS4 to finally become a reality – make of that what you will.
However, there is a catch. The catch is that while the method will be receiving a full write-up soon, we shouldn't expect to see this kernel exploit method in the hands of users in the foreseeable future. Flat_z made it clear in this interview that he would not publish the existing exploit as it his not his own work:
"Let's hope that someone will release a kernel exploit on 4.xx (or at least 3.xx), I myself can not do it because I am not the original author of the 2.xx + exploits and I do not want to release someone else's work."
So while the exploit exists and has apparently boundless potential, the PS4 hacking community will have to take a page out of Take That's book and have a little patience, for now. However, we are closer than we have ever been before to getting a full jailbreak, so the wait may almost be over.
What do you think? Will we see a full 4.55 jailbreak soon? Let us know in the comments, or post over in the forums with your thoughts.
