With some contributions from folks on the PS5 R&D discord server, SpecterDev‘s implementation of the PS5 Kernel exploit (via the Webkit entry point) has received significant improvements today, in particular with 4.51 support and significantly improved stability of the exploit.

PS5 Kernel Exploit stability significantly improved

When we first reported on the Kernel exploit, SpecterDev mentionned a “30% success rate”, meaning you’d have to retry the exploit multiple times before getting it to succeed. At the time, lots of people reported having to run the exploit 10 times or more to get it to work.

Yesterday, SpecterDev committed several changes to the codebase (a large chunk of those seemingly came from Chendochap), with the goal of improving stability. The effects are apparently massive, with testers on the discord server reporting that the exploit runs “almost always correctly”, and Specterdev saying it’s probably 3 to 5 times more stable than the initial release in his own tests.

So, this is not your typical “I tried something and it might help in some rare occurrences”, but more a massive boost to the exploit’s stability that turns it into a “works pretty much all the time now” exploit.

But there’s more!

PS5 Kernel Exploit now supports 4.51 Firmware

DizzRL and Valincius have added code to the exploit as well.

DizzRL has brought 4.51 support to the exploit! (And at this point we can fairly confidently assume this is the highest firmware that this exploit can support).

Valincius has added a quality of life update that will load the “user’s manual” correctly independently of your console’s language (prior to that, if your console language wasn’t en-us, you’d have to manually alter a few files in the exploit to get it to load properly)

Download and run the exploit

You can get the latest files of the exploit on the project’s github here.

We recommend you run the exploit yourself locally for the time being (our tutorial here), given that you’ll want to tinker with the files yourself a lot if you’re willing to help progress.
