      I understand its long, that’s why I bolded the parts that are important in his answers. This was necessary, its a big topic :)

      • moo

        One thing I do not understand:

        “but 3.56 and later change that so that flashing is more complex than just using the recovered keys.”

        What changed?

        And what exactly must be done for 3k/4k models?
        Does this leak help them in any way?

        • me

          I assume he means that Sony fixed their ECC private key generation so you can’t easily recovery the private key and use it sign an updater that the console will just run.

    I follow the ps3 scene just like i do the vita here… I just remain silent on the others. Been on 3.55 since it was current, loaded karoktos flawed cfw but got lucky and didnt brick… Stayed with that till rogeros update a few weeks ago. I encourage you to give us more updates as you can to keep me from navagating away from this site. Others would disagree, but i look for homebrew to incorporate the vita cross functions so it is valid here too.

    so now we make(ps3) …..frakenstine…..

    you should add,what can be done if you are on 4.xx

    • zoraktorok

      At the moment 4.20 can be downgraded with a hardware flasher, same as it was. Cfw for 4.25 will show up pretty soon because of this.

      • z3

        I also think that downgrade to 3.55 will only work if the PS3 came with this from the factory. If the PS3 came with i.e firmware 3.70 to begin with, then downgrade with a hardware flasher to 3.55 will not work.

  6. Pirate Cat

    Thanks for posting this, it ought to clear things up for the doomsayers. Here’s hoping that no one kicks out a way to install CFW on 3.6+ anytime soon.

  7. Astig_808

    nice work!i cant wait

  8. VinsCool

    OMG I can’t wait, that’s an incredible achievement. I’m ready for the next step… (I pray for an upcoming cfw for 4.xx wich could be installed without an hardware flasher.)

  9. Maxilus

    Can’t wait to get the Super Slim PS3 now!

  10. naki

    Great article!

  11. etertay

    wait. so that means that CFW for slims is inevitable? What about lv0.2 and all that?

  12. mike

    im on 4.25, i have an “old” ps3, should i stay on 4.25 and wait for CFW or would it be ok to update to 4.30? is it reasonable that there could be a way to go from 4.25-4.30 OFW to CFW without extra hardware any time soon?

    • Mr MaGoo

      not to sure. I would stay if u intend to go cfw in the near future. Sony released that literally the next day after they announced that they would be releasing 4.21 cfw

    • hammer

      only way to exploit ps3 is to downgrade to 3.55 with a hardware flasher.
      no exploit has been found for 3.6+ ,this means that any new exploit found has as much chance to run on current firmware as it does to run on older firmware.
      so if you like online play then I would just update if I was you.

  13. Bromanbro

    Thank you! I’m wondering though…if I want to get a PS3 that is vulnerable to this, should I get one now before Sony releases new PS3s with different lv0 keys?

  14. Leftthescene

    I left the ps3 scene a long time ago , my ps3 is still on 3.55 kmeaw cfw, it’s a slim, anyone in UK is interested? I only used it to emulator snes and stuff – piracy was never an interest to me, I’m selling it for £150 with 250gb , and all accessories ,in a perfect condition, iI don’t need the money or the console, I’m no longer a gamer, video games are simply too boring for me now – snes was to me the best console and that’s what I used my ps3 for(snes emulator).

  15. ajm_64

    being new to the PS3 scene and reading this just made my head hurt lol what I understood is I need to downgrade my current firmware first before I can make it a CFW..
    I wish we had a FAQ about this topic…

  16. YouDontHaveToKnow

    “Bootldr suffers from the same exploit as metldr”…
    That’s not true!

  17. Question

    I would like to know how it was possible to get the lv0 Keys?
    Nobody is talking of that.
    Also I never read how the dongle fraction could get games run 3.55+
    Woulf be gr8 if somebody could write understandable like here about the past and how it came to this right now 😉


    • ViRGE

      Marcan postulated on one possible method: using a hardware device to provide bootldr with bad data (fuzz testing) until it gave up control to the hackers.

      “For the exploit that we knew about, it would’ve required hardware assistance to repeatedly reboot the PS3 and some kind of flash emulator to set up the exploit with varying parameters each boot, and it probably would’ve taken several hours or days of automated attempts to hit the right combination (basically the exploit would work by executing random garbage as code, and hoping that it jumps to somewhere within a segment that we control – the probabilities are high enough that it would work out within a reasonable timeframe). We never bothered to do this after the whole lawsuit episode.”

  18. ViRGE

    Oh cool. I didn’t think anyone outside the Wololo forums would ever see this, so I’m glad to see this is helping more PS3 owners.

  19. j0k3r

    Hi @ all,

    I have a SlIM CECH-2504A with 4.25 on it. Does i have to downgrade these ps3 to 3.55 for using future cfw´s, or can i install these future cfws, on my ofw 4.25 ?

    thx in advance,


  20. squiggs

    uhhh.. i saw a report about the leak on bbc world news

  21. Minimur 12

    So is this ‘compatible’ with the old fat ps3’s ?

  22. vbrlogic

    stupid work

  23. oO Flowzilla Oo

    R.I.P Sony :(

    • z3

      Actually this is good news for Sony (good news concidering the situation). That you need to be on firmware 3.55 or use a flasher to be able to do this will limit how much this is used. A lot of people don’t want to open their PS3 to flash it, and a lot of people are on firmware 3.60+.

  24. ia

    Interesting news. However, I don’t see a lot of people are willing to risk their expensive PS3 for opening and downgrading it. In addition, there is the PS Plus membership to consider.

    If signing homebrews would be possible, even for a particular firmware (firmware by firmware), that would be great. Note: one could possible write an article about PS3 homebrews.

  25. kevin

    what about psn? will that be available to cfw users?

  26. miguel

    so i am on 4.25 ofw can i stay there and wait for cfw or do i have to downgrade my ps3 and with what

  27. Duff

    that feel when lv0.2

  28. Foot

    So let me make sure I get this right if I should wait I may be able to go from my current 4.25 OFW to a CFW as though I were installing an OFW without having to open and modify my console? I dont care bout the modding itself I hate the way it looks like my PS3 just shat its innards all over my tv stand. like wise I do have a PS+ subscription and I’m not overly worried bout losing it but I do still buy games from the PSN. Is it safe to assume provided the right console one can run a custom without fail that will be PSN able and the new cat and mouse game will be keeping it PSN able? Big Borderlands 2 player and loathe to leave the multiplayer online behind just yet…

  29. hmmm

    soy is not gona work on PS3 Slim Models CECH-3001A/B 4.25 OFW i shod jast update 4.30 OFW?

  30. Tha boss

    Will this make it possible to run backups and play on the psn without a possible bann or brick?? Or is the only way still duo boat loader true the dongel??

  31. xxmodnaRxx

    I want that PS3 at the top of the screen… (It’s probably photoshopped, but I don’t know.) Would be the best PS3 for putting CFW on. It just screams “Pirate”.

  32. Lorz

    Wololo…. What in the world happened to you? Your beliefs seem to waver in the wind? At one time you were all for giving users control of their hardware, now you’re calling firmware hackers “jerks”?

    I don’t get it? How can a persons beliefs change so radically overnight?

    I mostly overlooked the fact that you reneged on your boycott of sony by going right out and buying a PS vita… after all geeks love tech….. but with this…….. it’s getting harder and harder to respect you, or even take you seriously.

    Wololo, there’s an old saying… it goes something like this “If you don’t stand for something, you’ll fall for anything.”

    • Lorz

      *oops* I retract my previous statement, i see the two PS3 articles were not written by wololo.

      • Lorz

        Even still…. more power to the hackers!!!! BURN SONY BURN!!!!!

        • Jd8531

          Just to be clear, my view isnt on firmware hackers, its the dongle teams that decide to charge for exploits and hacks. Especially this one, who stole another teams work and wanted to profit from it.

          • Lorz

            Ok, on that point i agree, stealing someones work and then profitting from it… yeah, there’s not much more of an insult than that.

            I apologize for reading more into your statement than was actually there.

  33. XStationBR

    If sony update Hardware even will be able to launch games or eboot signed to run on theses new hardware then.
    Sorry but sony will and no would launch another new revision of Super slim at time just have one unique option.
    Acelerate new PS4.
    And try update system update all time.

    Maybe if the 8d CPU inside PS3 be used to security well all history can change but i can’t imagine this happens because these is a CPU for backup like RAID 5 is for HDDs on PC.

  34. illLoGiQ

    Quick question, is this structure from an old PS3 FAT? Like the first ones that came out with PS2 emulator built in. Im just asking cause (and dont chop my head) I was looking at lv2_kernel.self and notice root ps2_ (emu.self, gxemu.self, softemu.self) is this anything to do with the PS2 emulator. Would the layout look different on newer fat and slims who don’t have the PS2 emulators. Like would their be just Lv0 and Lv1? Noob question but was curious.

  35. ethomaz

    Hi @Jd8531, I liked your article but I think you forget to explain better which models the hack works because there a dude that read your article and didn’t understood it after all.

    The new PS3 that come with factory OFW bigger than 3.60 have a new lv0.2 without know keys (yet)… so these model can’t be hacked neither with lv0 keys or metldr method… the model are these shipped by Sony after July, 2011… the Slim CECH-30* (and some CECH-20*) and all Super Slim.

    Can you just confirm if I’m right/wrong or just update your article for better clarification just for that dude understand how the hack works.

    Thanks so much.

  36. Finaly

    yes i rely need know if my CECH-3001a/b gona work CFW in fucher

  37. miguel

    i have cech-3001 a
    does it work

  38. :( cry

    i jast got info on ps3 CECH-3001a/b 4.25 OFW u need 0.2 lvl keys soy jast update 4.30 OFW. CECH-3001a/b 4k not gona be CFW foret

  39. Joe

    Basically, people who have the launch ps3 fat and slims will have to keep waiting for a software downgrade method. Assuming that doing this will be difficult and there’s already hardware downgrading methods, I can’t see anyone putting forth the effort into making a software exploit.

  40. Luigi

    What’s a matter new Ps3 Super Slims +3.6, if my Ps3 still 3.55 Online PSN! \o/ Victory!!!!
