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.

I wonder if more PS3 exploits will be found considering tbe PS3 is basically dead?

Basically dead? Some games are still playable online, the PS Store is active, and TV apps work also.

It's going 15 years strong anc hopefully many more. Beast of a machine.

Unfortunately does not work for me. After sending goldhen if i start anything PS shuts off instantly.

Try a different USB stick, or MIRA instead of GoldHEN.

Great news. Good job to all the dudes working hard on the PlayStation scene, big thanks to SpecterDev, Chendochap, Znullptr, Sleirsgoevy,TheFloW...

Also may work on Ps5...Dilemma right there coz my Ps4 is dead... so do I run to the mall right now to buy a Ps4 slim @ $450 (or ps4 Pro @ $650, but no pro's have been in stock since corona hit) or do I get on the Ps5 waiting list to buy @ $1,000?

In October the ps5 waiting list was not too bad, they only had like 12 guys on the list and monthly re-stock was 10 ps5's so an 83% chance I thought, but the store attendants said only 7 guys had paid deposits so if I also paid a 20% deposit I'll be guaranteed to get coz they prioritize those who've paid.

well, the thing you've gotta remember is that you can only play ps5 games from the internal ssd, which you only have about 600GBs of space with stock, so that's maybe 10 games. and, those ssd that work with the ps5 can easily get over a grand, and that's in the states, so if your ps5 is a grand by itself, good luck with that. lol

Yes a $1000 ps5 of which I haven't even bought, the waiting list may be crazy right now with schools closing and Christmas coming plus news of this xploit may also boost sales. Local online stores have ps5's in Stock but @ $1200.

Storage wise no problem coz ps5 can transfer un-played games to external drive leaving only the games you are currently playing.

Biggest problem is the fact that the above store I trust and buy my hardware from only has monthly re-stock of 10 ps5 units so I risk getting a ps5 that may come with up-dated firmware.

Can't you just use the SSD slot as well?

 

[HellGhast]

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

... those ssd that work with the ps5 can easily get over a grand, and that's in the states, so if your ps5 is a grand by itself, good luck with that. lol

very expensive coz he says over a grand

Now..

Before everyone gets happy what is the success rate of this 9.00 jailbreak because if memory serves 5.05 and 6.67 had a higher rate for a jailbreak

also does that mean backport games are now available from firmware 9.00? I have no interest in updating my system if I can backport that's good

 

[AngryCinnabon]

If we get it working on the ps5 this will be groundbreaking!


And sadly a means for scalpers to go even harder on buyers with shit like (MODDABLE FIRMWARE)/(HACKABLE PS5) and charge like an extra 500.

Better and more stable than 5.05

Was reading this https://www.psxhax.com/threads/poob...t-via-chendochap-with-updated-payloads.10492/ and they posted the read me from the exploit which says it's better than 5.05 or 6.72

 

[Goku1992A]

I'll stand in the back and see I don't want to be a Guinea pig lol

 

[HellGhast]

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

 

[TheNintendoEnthusiast]

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!

I think backports will be a thing. Someone already got silently uploaded FIFA 2022 before this jailbreak went public.
