Clarifications about 3.73 (and 4.0) “jailbreak”

I tested the jailbreak on the latest firmware 4.0 since it was released and I can confirm that it still works.

Hi all,

I’ve been flooded with questions on twitter and I’ve read many posts on news sites and  I’ve seen some stuff being said on IRC and I thought I needed to clarify a few things…

First of all, I didn’t expect to see my tweet front paged on all ps3 hacking news sites.. although I should have expected it.. but anyways, the “jailbreak” is not ready to be used, at all. I only tweeted that because I was excited having it working and I wanted to share my excitement with everyone. But this is a bit equivalent to the day I released that script that created the very first CFW/MFW but it still took a couple of months before a real, easy, multiplatform and fully fledged solution was released : PS3MFW.

We are currently at the same state, I have the proof of concept, it works, but a solution that anyone can use where they just click a button and their PS3 gets jailbroken is still far from ready.

I’ve seen people say (and even write it in their front page news) that I’ll release it in two weeks after I come back from vacation. That is not true and I never said that. What I said was that for the next 2 weeks, the project is on hold until I get back.. but when I get back, then I will continue working on it, and it will then take some more time before it’s ready and released.

Some asked if it’s based on what gitbrew was doing/suggesting or if I used someone else’s exploit or work. No, this solution is my own idea and 100% my own implementation. However, the actual solution for the full jailbreak involves some components on which I will not work, and I expect/hope that someone else will provide the solution for that.

Some speculated it might be what I spoke about back in March which I later said I wasn’t pursuing by lack of motivation.. and yes, you are right. The same hack I had in March is still valid today, I told a few people about it (rms, Mathieulh, an0nym0us, and a couple more), but no one was interested in pursuing it further and actually exploiting that flaw (mainly because it requires a huge amount of work to get a proof of concept working). 10 days ago (I started on the 11th), I got bored and decided to start poking at it again, and yesterday (a lot faster than I thought it would take), I got my first pkg installed on 3.73 firmware.

On twitter, I said “do not update if you are on 3.55”, I said that in response to someone who said he would update.  Because of that, people speculated that you need to be on 3.55 first, and then install something before doing the upgrade. No, that’s not it, that would be useless. The purpose of my solution is to jailbreak a ps3 that is already on 3.73 firmware and which had never been jailbroken before. I told people not to update because, first of all, it’s not yet ready, and second of all, the 3.55 firmware gives you a lot more possibilities than what can be achieved on 3.73.

So what is this jailbreak? I won’t say because I don’t want Sony to block it in a firmware update (and yes, they potentially could) before it’s even released (and yes, I will release it when it’s ready). But I will explain this to you : in order to run your homebrew apps, you need two things. First, to be able to install them on the ps3, and second to be able to run it once installed. I did only one of these two things.

Some may say it’s not a real jailbreak, but the way I see it, there are three ‘jails’ on the ps3, I broke the first one which prevents you from installing anything, so now you can install your .pkg, great, but it won’t run, that’s the second jail. The third jail is being able to modify the firmware (peek&poke).

The second jail (running apps) is something that can be done, but it’s not my area of expertise (npdrm algo), so I will not be working on that. I am waiting for someone else to achieve it (some have succeeded but do not wish to release it, at least not for now) then I will release.

The third jail (modifying the firmware) is not possible with my method, this means that you will  not have a “CFW”, you will run your homebrew applications and games on an official firmware. This also means that without peek&poke support, none of the backup managers will work. So, again, my solution is piracy-free, and as always, I do not plan on working on a way to enable piracy (or even legal backups).

Overall, the purpose will be to allow people who are on 3.73 firmware to enjoy the homebrew games that were released, to play a bit with Eskiss, and to use Showtime for playing their movies. This should be more than enough for everyone.

Finally, I will conclude by replying to another question I received : Do you accept donations? The answer is yes. I do accept donations but I do not seek them out. I will include a donate button to the bottom of this post, so if anyone wishes to donate, they can do so, however, I want to make it clear that whether or not you donate does not and will not affect in any way, the release, or the progress of the work I’m doing. If you donate, you would do it as a sign of appreciation of my efforts, and not in exchange of any favors or anything crazy like that.

That’s about it I think… If you have any more questions, please refrain from asking them, I get enough as it is already.. I also said everything I needed to say and I don’t want to give any more information than that (for now).

  1. Contamos com voce,só voce poderá tirar agente da lama pq se continuar assim nós eo ps3 iremos se afundar juntos.rsrsrs.abraços

  2. Kakaroto please remove this moddingst*** SPAM, its obvious that those comments are placed to push this site

    • I thought it was spam, but I think it’s just the mod from their forum who asked people to show their support. I checked, they all have different ips and seem to be from different people. Only have gave the url, others just stated the name of the forum without any link to it. it’s fine to leave it there.

      • You are right KaKaRoTo, a member of our forum suggest us to thank you, because we had an internal argument some times ago about the insults to you and other of your friend devs… so we want to show you that we support devs… we absolutely don’t want to spam your blog. If you want, contact me please. Hi and good work!

        • Yes Kakaroto, we are all Italian members of that Forum and we are all on your side, againist stupid 13years old convuls gamers, or “bimbiminkia del cazzo”, that runs the scene of our loved ps3. Programming, or hacking is not a game(for crazy stupid 12 -13-14….30), and those people don’t know what it means. I know that you are a great DEV, and i think that you have to feel fine just for this, and then even to other yours motivation 😉
          Continue to work for us and if you need an italian “secret” beta tester for your work i would be very happy to help you in this batle for sony and for our rights to make homebrew and so much other in our PS3!!!
          Good, god(as tel from nother one) WORK!!! You are the BEST!!!

  3. Great job. It is quite silly people get all pissed just because someone won’t release their work. What math does is great and is the proper way to help. Math figure stuff out and if he just hand feed the other developers, they wont learn as much as figuring out themselves. Math does give hints to push people in the right direction.

  4. no spam ….questo sta a significare che ci sono molti utenti di questo forum che stimano kakaroto e che lo apprezzano gia’ x il contributo che ha dato fino adesso ……..

  5. People are so un respectful! I dont understand why they can injure, hate, and wrote so bad thig about the real hacker who try to make the underground foward! I think those people are just jalouse because they live with no hack skill! 99% are just user of hack that it! I am of those! And i am thankfull to you kakaroto, to mathieulh, to darkalex, and all other people who had work so hard to give us the opportunity to use our ps3 with new feature! Mkv, emulator, homebrew! That just awfull! A Big Thank from France!

  6. Grazie Kakaroto per tutto quello che stai facendo per tutti noi.
    I rischi sono alti, ma tu continui a lavorare GRATIS per noi.
    Voglio che tu sappia che io come molti altri appoggiamo il tuo lavoro e il tuo operato.

  7. Kakarot Thanks for everything you are doing for us all.
    The risks are high, but you continue to work for us for FREE.
    I want you to know that I like many others we support your work and your work.

  8. Grazie per tutto il tuo lavoro e quello degli altri …Quelli che si lamentano sono buoni a nulla che vogliono tutto e subito senza nemmeno capire che ci sono sforzi da fare e voi fate tutto questo in modo del tutto gratuito. Non vi scoraggiate quelli che parlano male sono in minoranza ve lo posso assicurare continuate cosi ragazzi GRAZIE e magari ci fate un bel regalo di Natale :-)))

    I apologize for my bad English

    Thank you for all your work and that of others … Those who complain are wimps who want everything at once without even understanding that there are efforts to do all this and you do so entirely free. Do not be discouraged those who speak evil are in the minority I can assure you guys keep it up THANKS and maybe make a nice Christmas gift :-)))

  9. Hi! My name is Rafael Cardoso and i am from Portugal.

    In my school you are a GOD!
    Everyone of my classmates are big fans of KaKaRoTo. Everyone is expecting that wonderful news that is the new CFW release. So don´t dissapoint me and my bros.
    Release it when its done.

    Please, share with the world your knowledge, and that would be the best Christmas present to all.

    Continue the “God” work !!!

  10. Thankyou so much for your amazing progress.
    Your work is very appreciated by most of the scene including me:)
    Don’t let the haters get you down, most of the scene are behind you and are very greatfull 🙂

  11. How do you let people on the internet make you depressed ? Your hackers, you should be able to take some criticism. The fact that you could go to jail for what you’re doing should make you depressed. If I were you guys I’d stop posting updates on your work acting like your going to release it and then expect people to kiss your butt in order for you to release it. I’ve never seen anyone do that.

  12. Hello kakaroto how do you do
    how many days will work 3.73 cfw
    that is released or not so many members is waiting in latest hacking so how many days will released please tell me the answer you released in christmas or new year 2012 so please clarify the answer
    THAN Q

  13. grazie a te ke stai rischiando tantissimo per noi lavora con calma e lascia perdere quei figli di puttana che ti offendono.

    thanks to you, you are risking a lot for us ke works quietly and forget those sons of bitches who offend you.

  14. Very big thanks to all of you guys ! All you have already done is hudge ! If you stop working on it, no problem, we will understand. Shame on you haters !!!

  16. Hi kakaroto.
    First of all,i want to say you: THANKS!
    Thanks for the hard work that you are doing….i have a ps3….i was on 3.55 firmware but thanks to a game it upgrade to 3.70… problem for this ’cause i believe on you.
    I believe on all Dev-Team who working on the PS3 Hack Scene…you have all my support man,do this job and pown the SONY! GO MAN YOU CAN DO IT!

  17. I find it funny that people after trashing Mathieulh for so long, now make him a god and starting to praise him… all they can see his CFW, CFW… dont be dissapointed, but maybe if you read Kakarotos clarifications again: “…The third jail (modifying the firmware) is not possible with my method, this means that you will not have a “CFW”, you will run your homebrew applications and games on an official firmware. This also means that without peek&poke support, none of the backup managers will work. So, again, my solution is piracy-free, and as always, I do not plan on working on a way to enable piracy (or even legal backups).

    THIS WILL NOT ALLOW PIRACY! (and thank you Kakaroto for that…)

    • Yeah that’s hilarious. Wai, I’ve seen that done with PSP. The good ol’ days lol… Can’t wait for this. I don’t know if I’ll be updating, but I know some friends currently updated that will like it. 😉

  18. i’m excuse me for my english but i want ringraziarti for everithing that you and other dev do !!! thanks you !!!

  19. kakaroto, all brazilians people loves you, you are the best and aways the number one, tks

  20. well, good news and bad news… Good news is that JB is possible, bad news…is your thinkings about community… 🙂 i dont want to teach anybody, i just surprised… you know… human is such human… and 30% of idiots is a part of any community…so sad, that this idiots is most active part of any community, and sad that they annoying your so much… I think its a most angry and active idiots because most of them 15 years (or 30 years – horrorrrr!!!!) crazy stupid gamers …
    But then you think to take JB in full secret, just because of your disappointment, why dont your think about 70% of good guys, who not disturbing you and just sadly thinking about their losses??? 🙂
    I understand you so much, i am a kind of enthusiast too but in other sphere not IT related/
    And i facing with such problems every day…And i facing it literally… face to face,eyes to eyes…i`m involved in teaching…
    And if one of this idiots ruining my day… i just think about good guys, who really can appreciate my efforts… Please think about good guys too 🙂

  21. I dont really care too much if the Jailbreak 3.70+ will be released this year. I would if you sir Kakaroto could realese a cheat system for the new JB. Also if could deal with E3 Flasher’s ROGERO custom firmware that is installed after downgrade the PS3; and the you may can create a “cheat device” for PS3. Off-line only off-course. Now you know I’m a old school gamer and a dirty cheater.
    Cheaters would love to bring the old style of gaming to the last gen plataforms…

    This soft must be an easy creation for a great hacker like you.

    I had to say thanks anyway cause you are bringing the possibility to jaibroke lastest PS3 firms.

  22. Hey KaKaRoTo!!! You’re amazing, and doing an awesome job!! I sold my PS3 when I moved from Japan to my home country, but I plan on getting a new PS3, and donating to you once I start working again!

    I just wanted to thank you for all your hard work, and to ignore the ignorant anti social posters spewing negativity towards you. :/

    • But it will lead to homebrew being able to run wouldn’t it? I know a few people that have been waiting to use some arcade emulators but had to update instead to keep psn xD. I mean the finished version of his cfw. Since he says it’s not currently finished yet.

  25. grazie Kakaroto di quello che fai per tutti noi che aspettiamo con ansiam il tuo aiut che sara prezioso per poter andare avanti grazi buon lavoro xd

  26. Its just a matter of time till someone makes it a cfw this is just a start of things to come but it don’t h well at leastwise we got hope that the immpossible is possible ty for ur work kakaroto

  27. Thanks for what you do !!!!

    Thank you for the great job you’ve done and for things you’ll do in the future…

  28. Kakaroto sei grande!! Non dar peso a gente che si gratta dalla mattina alla sera e dimostra a tutti che il tuo lavoro non dipende da altro che dalle tue competenze e dalla tua passione!! Math capirà anche lui che al mondo di coglioni ce ne sono tanti… Forza kakaroto you Are the one!!
    Per tutti coloro che si son divertiti a fare i gradassi, andate a lavorare teste di cazzo!!

  29. I’am from brasil, i have a ps3 and I understand you, and I agree with you, and I think you’ll know the right time to realise the ps3 cfw.

  30. Hey Kakaroto, i´m from Brazil and i’d like to say that what you, Mathieulh, and all the devs of the scene, specially because here in Brazil the taxes are really, really high, and if you think in EUA the games are expensive, you have no ideia what is here…

    For an example, a Ps3 160 GB is about 650~800 dollars, and a game usually is about 130~150 dollars…So, your job allows me and a lot of my friends to play, otherwise we would never have a ps3, cause even if we could buy one, there is no way to keep buying games…

    So, i think a say for all of them, thank you very much, and even if Mathieulh or others devs dont want to share your progress with us , what you guys have done so far is simply enough for a long time!

    Sorry for my English

    Keep Working please!


  31. I have a CECH 3001A Model. Are these currently un jailbreakable?
    Thanks for the reply.

  32. Hy my friend, we of all places of the world, (who has one PS3), Have faith on you! You are our hope to play everything that we want!
    So, dont’t care about any flame, because some people didn’t know what they say. Keep pushing, and set us free!

    Thank`s. Bye Bye.

  33. Hi Kakaroto,

    I’d like to thank you as a Moroccan for what you and the other developpers from the PS3 scene have done for us. The praise you deserve is not only for allowing us to play games for free but also for pushing the limits of the Playstation 3 and enhancing computer security along the way !

  34. ciao kakaroto,
    volevo diti grazie per il lavoro che stai facendo e mi dispiace che certe perso ingrate offendano
    Mathieulh perchè non vuole condividere il suo grande lavoro.
    spero al piu presto che riuscirai a trovare un cfw
    😀 😀 😀
