PS5 Exploit: Debug Menu + JAR Loader (BD-JB Version)

Developer John Tornblom has added debug menu support + a JAR loader (based on Hammer 83’s work) to his kernel exploit implementation on the PS5.

The debug menu might feel a bit overwhelming at this point since it’s been enabled on the webkit exploit for a while (that, plus he actually submitted that code change a week ago… we’re a bit late), but folks running on the BD-JB exploit appreciate this feature.

More important, I think, is the JAR loader, which basically allows you to load a Java binary (rather than a typical ELF file, as is the case with the current implementation of the Webkit exploit). Developer Hammer 83 provided such an implementation yesterday (here), and John added similar functionality to his repository shortly after.

I have a feeling that people who are unsure about creating an ELF file using the PS5 Homebrew SDK will be happy with the ability to send Java files to their hacked PS5 as payloads.

PS5 Exploit – Webkit or BD-JB, which is best?

When we see these versions competing with each other when it comes to webkit implementation or BD-JB implementation, many of us scratch our heads over which is the best way.

There’s no clear winner at the moment (well, if you’re like me on a digital PS5, you don’t have a choice, it’s just Webkit). In terms of stability, both exploits appear to be fairly reliable, although some people have said that the webkit exploit is generally easier to work with.

The webkit exploit would certainly be the way to go if we want to capture as many users as possible, but things might not be that simple. Ultimately, it will depend on which firmware (and exploit pair) makes progress in hacking the PS5 hypervisor. Rumor has it that firmware 3.00 fixed significant issues and people who stick with lower firmwares could be rewarded in the long run.

PS5 BD-JB + Kernel Exploit – Download and Run

You can download John’s latest code here:

Building instructions are included in the readme file, but as a reminder, the goal is to generate an ISO file that you’ll burn onto a Blu-ray disc. The ISO is designed to take advantage of the BD-JB exploit followed by the IPV6 kernel exploit to allow you to run unsigned code on the PS5 (you need a PS5 with firmware 4.51 or lower).

You can find Blu-Ray burners for relatively cheap prices on Amazon and other retailers (make sure they support BD-RE and Dual Layer DL). TheFloW has stated that it used Verbatim Rewritable Discs (BD-RE) in its experiments. (affiliate links)
