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.

Hi all,

Does anyone know how quick is Sony in updating new and unopened PS4/5 consoles from the factory with the latest OS software version?

I know Apple is very proactive with shipping latest iDevices with latest system software, but I just bought an extra Digital Edition PS5 (which is set to be shipped in a couple of weeks) and I am wondering if it will come with the current / latest PS5 software (Version: 21.02-04.50.00), or perhaps hopefully with the one that dates back prior to 1st of December (aka version: 21.02-04.03.00)?

Would highly appreciate any input!

Is it true every time you boot up the console you need to do the steps or is it permanently done once?

it's not a coldboot exploit, none of them are. you have to redo it every time you power off.

think it's in @KiiWii 's aio thread. just input both numbers.

It's also literally the first result on google.

yes, I often forget to quote people.

Went from 7.55 to 9.00 last night and can say this exploit works almost every time. Takes less time then most of the other Ps4 exploits to perform and just..... works. The VR headset insisted it needed an update so did that as well, all working perfectly.

Absolutely glorious.

great news! I also hope for PS5

It's so crazy how incredibly easy it's become to jailbreak modern consoles compared to all the hoops you'd have to jump through to jailbreak consoles way back in the day. The thing that took the longest was just updating to 9.0.0. Now I just can't wait for a permanent cfw. I knew zero about ps4 hacking until yesterday so I was unaware about there being nothing permanent yet but that's exactly how the Vita was for quite some time so I'm used to it. Now I just wish I had a ps4 pro instead lol.

Anyone knows if a brand new PS5 has to be activated online and updated on the initial setup like the Xbox One (maybe also XSX)? If that's the case I guess it doesn't matter which firmware it comes with if updating to 9.03 is mandatory to be able to use it.. Or am I wrong? Been a few years since I started a brand new Xbox but I think it had to be updated on the initial startup? But if that's the case I hope Sony hasn't used the same method.

No you don't need to activate it online
I got a ps5 and can say so

 

[godreborn]

no need to activate as the licenses are being resigned as "free," if piracy is your interest.

Piracy? Why do you say that? I'm interested in homebrew. Are you saying I could potentially install homebrew on the latest FW and just piracy requires a specific FW? I thought the jailbreak needed a specifik FW no matter what kind of unsigned code you wanted to run?

 

[godreborn]

well, then you can do it either way.

I might get a ps4 just for this but I have a question, is the online bans similar to switch, like once you load this jailbreak once, will you get banned even if you don’t use it afterwards.
