PlayStation 4 OFW 9.00 Jailbreak released, can reportedly affect PS5 consoles as well

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.

The article says it works on firmware 9.00 and below. Does it also work in old exploitable firmware? or higher than 7.55?

wait is it not? It's successor came out a year ago and because it's a blu-ray player it's gonna get updates for a while just like how the PS3 still gets updates so if you go by updates it won't be EOL for a very long time

The PS4 still gets games released for it, though. I guess that's really when we call it end of life: as soon as it no longer gets new releases regularly.

    @Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.

    They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".
  • Veho @ Veho:
    It's a DS Lite in a slightly bigger DS Lite shell.

    It's not a Nintendo / iQue official product, it's a 3rd party custom.

    Nothing special about it other than it's more comfortable than the Lite

    @SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme

    but that's a long shot

    i think only the red mario kart edition phat was v5

    A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."

    Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.

    I don't pirate them, I Use Them :mellow:. Like I do @BigOnYa 's couch :tpi::evil::rofl2:

  • cearp @ cearp:
    @BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.

    The issue is DRM
  • cearp @ cearp:
    You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60

    :rofl2:
  • cearp @ cearp:
    still, I agree physical media is nice to have. just pointing out the issue is drm
  • rqkaiju2 @ rqkaiju2:
    i like physical media because it actually feels like you own it. thats why i plan on burning music to cds
