There's a new PlayStation 4 exploit in town--PS4 scene developers have released pOOBs4, a new kernel exploit that affects consoles on firmware 9.0.0. According to the pOOBs4 GitHub page, this exploit functions a little differently from previous PS4 jailbreak methods; you'll need a dedicated USB drive with the jailbreak software, which you'll insert into the system at a specific time during the process. The hack can also work on the PlayStation 5, claims the team, but triggering it isn't possible yet, and they recommend that users don't try to mess with their PS5 consoles until more information is available on how it affects that system. Currently, any PS4 that is on OFW 9.0.0 or below is exploitable using this method.

In this project you will find an implementation that tries to make use of a filesystem bug for the Playstation 4 on firmware 9.00. The bug was found while diffing the 9.00 and 9.03 kernels. It will require a drive with a modified exfat filesystem. Successfully triggering it will allow you to run arbitrary code as kernel, to allow jailbreaking and kernel-level modifications to the system. will launch the usual payload launcher (on port 9020).

The instructions and jailbreak file itself can be downloaded from the source below. Useful homebrew tools Mira and GoldHEN have also been updated to work with this new version.

• You need to insert the USB when the alert pops up, then let it sit there for a bit until the ps4 storage notifications shows up.
• Unplug the USB before a (re)boot cycle or you'll risk corrupting the kernel heap at boot.
• The browser might tempt you into closing the page prematurely, don't.
• The loading circle might freeze while the webkit exploit is triggering, this means nothing.
• This bug works on certain PS5 firmwares, however there's no known strategy for exploiting it at the moment. Using this bug against the PS5 blind wouldn't be advised.

You have a dilemma then. Better play it safe and stay on 5.05 and hope for back-ports.

Me thinks I'll buy a 2nd ps4 coz my 7.55 is working intermittently, or cough out a grand for a ps5

Oh no I'm totally fine the 6.67 CFW PS4 that I have has been sitting inside my storage for 6 months I have a legit PS4 that is on the latest firmware and I have the majority of the PS4 games...

I had wanted to copy a disk to my PS4 but they say I have to copy it twice (which is stupid) to make the fake PKG... but I'll definitely keep my eye on 9.00 now the only issue I see with this in the future is the exploit isn't permanent and you NEED internet to run it.

I haven't turned my PS4 on in a few months. Maybe I am at the lower version. If I am I would love to mess with this!

The PS4 here wasn't used for weeks or even months and it didn't automatically update the FW so you're probably good too.

This makes it worth upgrading a PS4 with 500GB to 2TB or more.

you should be able to self host, so internet isn't needed.

Oh that's nice. I updated my PS4 Pro to 9.00 to play the Elden Ring Closed Network Test. So this is a nice surprise.

my brother updated my ps4 yesterday brb gonna go jump off a cliff

 

[tpax]

That's good news. I absolutely don't care about the PS4, or consoles in general (minor exceptions may apply). But hearing about a new exploit for any console being released always triggers some kind of nostalgia and joy in me.

i just updated to 9.03 yesterday after turning my PS4 on for the first time in a year

I updated 1 hour before it was released because i couldn't buy crystals on genshin impact, since i originally made an account on psn.

You can actually, but m.2 ssd that meet ps5 specs are expensive

Not that expensive compared to normal SSDs https://www.amazon.com/WD_Black-SN850-Internal-Gaming-Solid/dp/B08KFS6THF

@godreborn & @ut2k4master

Hmm interesting I will look into that I was always under the impression you always needed internet to activate the jailbreak

 

[godreborn]

I've been using my sandisk connect. it's a wifi stick that doesn't connect to the internet. its main function is streaming from one source to another I believe. however, it can be used with the ps4.

i just block internet access for the ps4 on my router its still able to connect locally to my pc

Howe stable is it? I might try it out if its not so bad in comparison to 7.02

So far, I have tried 5 times and was able to run goldhen 5 times. I tried a few homebrew apps, but some of them crashed the console instantly. Maybe the apps need to be updated to 9.00, though.

I didn't know Goldhen had been ported to 9.00, any host links?

 

[ut2k4master]

dont know if links to that are allowed but it has a github

 

[godreborn]

You can link to goldhen. Goldhen is even in resources on temp, just not the 9.00 one

 

[digipimp75]

Nice. I'm still on 5.05 haha

 

[wiiando]

Ye I've got the bin already, just being lazy to self host


NVM Karo has updated for 9,00
