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'm not joining the ps5 scene, so it doesn't matter to me.

same here not wrecking an all digital console for it just to be banned

 

[Jayro]

Ugh, they can never seem to release one for the latest firmware, and that's really annoying to most users. :/

I may still exploit my system, just won't be in the scene. Same douche bags from the ps3 scene were in the ps4, and I don't think I can take their efaming bullshit in another scene. If people would read something, they'd know their full of shit and they wouldn't praise them.

They don't want people going online with this stuff, which is fairly sensible.

 

[godreborn]

Would also be easy to send up a red flag to Sony if you're pirating, because all fake pkg games' licenses say free in the name.

 

[tabzer]

I don't care about the games, have 0 saves for pirated games after all these years. Are you wanting to know what to do with your system?

Yeah, pretty much. I've got like 5 cfw systems which all contribute something unique. My PS4Pro is collecting dust.

Wonder if this whole "don't update if you want HB" thing is gonna catch on..

You can get your eap key with your sfash0 from the dev partition, just requires python, pip, and 2 dependencies. You can backup saves or activate your account once those have been updated, use ps4 saves on ps5, even change accounts if you're ever afraid of being banned, delete your notifications.db from system_data/priv/mms to remove traces of what you've installed, backup the other 3 databases, can even hex edit it to change user id's. Backup and restore trophies, I guess psx and ps2 games, but it's not perfect.

The question might be a bit silly, but you don´t need a working disc drive for this, do you??

Okay. So maybe playing around with/editing saves or potential mods to ps3 games would be the unique uses of a JB PS4. For the most part, I was already able to move my saves from PS4 to PS5--but there was a time that changing their linked accounts would have been appealing.

It's actually less silly than you think because I think you can't do certain things without one, updating being one of them if I remember correctly. However, you should be fine to jb it and install your... 'legal' backups.

any brand new PS4 will be 9.0 or lower.

9.03 is only 2 weeks old, so now is the best chance to try your luck with used consoles, too.

Already found an 8.50.. Maybe it'll arrive next week.. Any idea if you can stream PS4 games on the switch?

There's a tool called "Chiaki PS4 Remote Play" on the switch, but I have no idea if that works.

 

[retrofan_k]

So if I stay at 5.05 fw, do I still need backport for everything I play or what?

Yes.

That works even for PS5, even over internet. It should work with PS4, remotely, but it probably requires PSN login to work over internet.

Tried this on latest firmware PS5 (I disabled firmware updates and it still updated). The exploit loader page shows no URL, just a white screen and no pop-ups.

 

[maoex]

I know the warning with the usb stick. but now i wake the consele up from rest mode, kernel panic, reboot and i become these "Kernel Heap" error, but i didnt put usb stick inside. i hope its not bricked forever... ??
Thx for reply

 

[BixNine]

This sounds awesome. Need to get an extra ps4 to test it out

 

[eriol33]

Cool. Have you pirates, finished at least 10% of your pirated PS4 backlog games

Nah not really. Thats actually a great question b/c before I became a bloody pirate I 100% 2 games. Now I just look at the title screen....

I haven't even finished 10% of my purchased PS4 backlog games.
