PS4 7.55 Jailbreak released

The 7.50 PS4 Jailbreak released by sleirsgoevy yesterday (and based on TheFloW’s kexploit disclosure from January) has been confirmed to work on 7.55 “without change” by Sleirsgoevy himself.

I can confirm that this exploit indeed works on 7.55 without any changes. Still no Mira/HEN though.

So, this means we technically now have a jailbreak for Firmwares 7.50/7.51/7.55. However, some significant issues remain with this release, and hackers are hard at work to correct them.

The main issue seems to be that on 7.55 at least, even when the exploit succeeds, payloads cannot be loaded, except for the rare occasion. This has been reported by Zecoxao yesterday and other people on the scene.

todex payload works on 7.55. however, you can only make it work with the bare minimum: syscall 11 and the right offset: 0x222898D

Additionally, multiple people are reporting low success rate running the exploit itself, with some people mentioning running the exploit crashes the browser 9 out of 10 attempts. This might or might not be fixed, considering a lot of the instability comes from the underlying webkit exploit, not the Jailbreak itself.

Furthermore, there is no functional HEN (Homebrew ENabler)/Mira(CFW) for this jailbreak yet, meaning people can only tinker with minimal payloads to confirm this works on their end. Still fun, but probably not what most end users will be comfortable with.

In other words, the scene now has access to a PS4 Jailbreak up to firmware 7.55, but some additional work is required to make it user friendly.

PS4 7.55 Jailbreak quick FAQ

Here is a short FAQ for those of you having questions. Keep in mind that we’re very early in the game, and things can evolve pretty quickly

What’s next for this PS4 7.55 Jailbreak?

I believe various hackers will be working on the following things in the days to come:

1. Fixing the payloads issues on Firmware 7.55
2. Fixing general stability of the exploit on all firmwares, to the extent possible (Sleirsgoevy is apparently still working actively on that)
3. porting Mira/HEN payloads for end users to get a “Custom Firmware” experience.

These things could take days, or weeks. In general the scene tends to work in matter of days once a Jailbreak is published, but this exploit has proven to be fairly difficult to implement (it was disclosed by TheFloW 2 months ago), so set your expectations accordingly.

I’m on firmware 7.50/7.51/7.55, what do I do? If I’m on 7.50/7.51 should I update to 7.55?

For now, people on firmwares 7.50/7.51/7.55 should stay put, and play with the files that have been released (download link below) if they want the thrill of attempting the exploit.

But, and this is particularly true for those on 7.50/7.51 wondering if they should update to 7.55: do not update your console. We can’t predict what tomorrow brings, and for all we know, once tweaked, the exploit will work way better on 7.50 than 7.55, for example. It’s easy to update to 7.55, and practically impossible to downgrade once you’re there (not without solid hardware skills, at least).

I’m on firmware 7.02 or below, should I update to 7.5x ?

Absolutely not. You’re on a firmware that has a fully functional jailbreak, you have no good reason to update at the moment. When the 7.5x Jailbreak becomes more usable will be the time to ask that question. But that’s not now.

I’m on firmware 8.xx, is this for me?

No. Stop updating your console firmware, wait patiently for future breakthroughs in the scene, or try to get yourself an exploitable PS4.

Download and use the PS4 7.55 Jailbreak

If you want to verify that the jailbreak works for you, you can try it out.

You can download the PS4 7.55 jailbreak here. For those of you having difficulties loading payloads, (in particular if you’re on 7.55), you might want to try Zecoxao’s todex payload test, the only payload really confirmed to work on 7.55 for now.

You will need to host it on a personal server, and point your PS4 browser to your local server’s url. Alternatively, this will most likely be hosted on third party within the next few hours.
