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).

Kakarato read the articel about flaming on math, and I agree with you, I also called him fake and an a** for not wanting to share his work and I want to apologize for that, I did nothing for the scene, just some reps for your devs work, but I enjoyed playing games thanks to YOU guys. So please let Math know that there are people out there that understand why he not wanted to share.

  6. Brother, you are correct with your posture, we look forward, however we can not let our emotions speak louder and verbally abused people, who can root for this update release more posssamos to be free. I’m from Brazil and support you in your convictions!

  7.

Thanks for your help is really appreciatted.

      pay no attention to these 15 year old trolls they all deserve to go back to there holes where they belong 😉

  11. Hello Kakaroto!
    I want to say thank you to you and all the other devs for the immense work you are doing.
    If ever one day succeed in making the PS3 a free system will only be for your works.
    Keep it up! There are many people who appreciates you, do not listen the children who make fun of you. We respect and we are envious of your brain! 😀

    a hug


  12. hey kakaroto there a wicked guy doing big things for the scene to i don’t if you’ve heard of him just trying to give ya the heads up mate 😉 his called tuhta and had been working on the 3.73 until the new update came out. He’s now working on the 4.00 so maybe you two could do the fusion dance and join forces to save the day 😀

  13. Sorry Kakaroto, but i will never kiss Mathieulh ass. You have good heart, but Mathieulh is an arrogant prick… only he knows everything, but don´t tell anyone… can´t support him…

  14. Mathieulh Mathieulh
    @ @KaKaRoToKS actually I did share the whole algo minus the part you need to run the npdrm on 3.56+ that’s as far as I am willing to go.

    This is fresh tweet from Mathieulh… why does he does not share all anonimously?! Why does he want always the e-fame? I can´t support this Mathieulh… we are like dogs, begging for bones…

  15. Hi kakaroto, I’m glad you are back on the ps3 works and hope you manage to make us all happy, and what math is concerned, he always makes things knows what he did with the ps3 but do not want to share with us will I can not strange that some people angry, but that aside he should anyone penalties are overjoyed was I do not think there will always be people who assholes are there you can not help, I hope you two together to share and together with the honor reap the ps3 jailbreak, greetzzzzzzzzzzzzz

  16. Good day my friend!

    I would like to congratulate you for the excellent work he has done in the PS3 are people like you that we welcome and we are very grateful for the masterpieces, especially in the work done on the PS3. We are anxiously awaiting the launch of this new CFW 4.0 for the same where only gods are capable of this feat without charge from us. I hope you can help or contribute in some way with you in the future and now verjuice heart. Thank you

  17. And this CFW illusion is going and going…

    Read the “clarifications” from Kakaroto, the man himself: THIS WILL NOT LEAD TO CFW 4.00. THIS WILL NOT ALLOW TO RUN PIRACY BACKUPS….

    Kakarotos is agains piracy and thank him for that!

    How hard is to understand that?!!

    • Yeah but you can´t stop the river and part of his job is openning the door .. Sony got that deserved fuck sony greed corportaion.

  18. Kakarot Hi, We support your work with the new cwf4.0 and we are all looking forward to the release.

    Thank you for your dedication to this work.

  19. The Internet is an amazing thing…

    Charles, read the words from Kakaroto. But, please… read them slowly:

    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).

    • lol, hi @jackie653,
      yes, it’s an amazing thing.. you notice how many comments I get and how many I don’t respond to.. everyday is the same question about “cfw”. I suggest to ignore those who cannot read, I get tons more on twitter, and we can’t just reply to everyone since they already proved that they can’t read…
      just relax, and ignore the questions about ‘cfw’, you’ll be insane otherwise 🙂

  20. Hi man!!
    i’ve got an idea for you that can take you some money…
    when you or someone that works with you have something to release you should create a filesonic account, put what you got in the server and then everytime there’s a download filesonic give to you a little money. In this way you can legally share something and also make some money that maybe can help you devs to continue the research.
    Anyway I TRUST IN YOU and most important things i hope you’re not afraid of the people words, cause the haters will be the first to use your cfw! i’m sure that your work will be really appreciated and so the kakaroto name 😉
    see you soon
    p.s. sorry for my bad english but im italian!

  21. Forgive me for not introducing myself.
    I am from the United States wondering if you devs could by my apprentice and teach me the ways of the PS3 Programming “language”. I have a very (small) history in making html and java applications, so I know nothing about C or any of that. I do however have a friend willing to teach me about hex and elf.
    If you are not willing to teach me, then could you please direct me to some source of info showing instructions on how to do the amazing stuff you guys do. If you would. Please. The CFW world is not at its best right now, I would like to help.
    I’m one of those sad souls stuck on 3.72.
    If you could please reply I would be thrilled.
    Also, If any of these emails get to one of you,
    You guys are awesome. 🙂
