Sony PlayStation 3 Hacker KaKaRoToKS JailBreaks 3.73 PS3 FW?


Sponsored Links
139w ago - To follow-up on the previous article where Sony PlayStation 3 hacker KaKaRoToKS stated "A solution for 3.60+ will be available soon, so no worries - people just need to be patient" comes some more Tweets today on JailBreaking 3.73 PS3 Firmware.

Below are some of the recent announcement [Register or Login to view links] from KaKaRoToKS on JailBreaking PS3 3.73 Firmware, as follows:

  • I will reply.. but I didn't read... yes, file managers and FTP should work fine.
  • and I'm all for competition, no worries. I do this for fun, not for race or whatever. Also, 3.73 cfw is not possible
  • i dont know yet about emulators... All in good time. There s no rush
  • yes, that's the point, to run homebrew.. showtime should work fine. not tested yet.
  • Nope, completely software based.. I won't say anything more than that for now to avoid them blocking it before release.
  • The "kind of" meant I need to fix NPDRM algo for it to run. And no, this will not allow backup managers. And no, it's not a CFW
  • 1 - I won't share it until it's ready to use (still a bit complicated + some missing components), 2 - don't update if you're on 3.55.
  • Updated my ps3 to 3.73... oh and THEN I jailbroke it! (kind of)

Here is to hoping this is indeed the working solution PS3 scene users have been waiting for, as previously KaKaRoToKS jumped the gun confirming the PS3 Downgrade Success from 3.55 to 3.41 Firmware and then Tweeted "sad news.. downgrade worked, but not reliable, only works with one of Xtse's ps3s, but can't reproduce it.. I'm going to look for another way. nope, it only works on one machine, even if same model, it doesn't work on it. No idea what's different about it..."

Since then, KaKaRoToKS has released a PS3 Expedite Benchmark Tool and Engine Ports, an Eskiss PS3 Homebrew Game and a PlayStation Move Support update for the Eskiss PS3 homebrew game though.

Finally, from IRC on the PlayStation 3 Firmware 3.73 hacking developments:

[KaKaRoTo] heri, docpaul showtime would work fine
[sandungas] kakaroTo, this means new tcl patches for mfw and some changes to manage 3.73 ?
[KaKaRoTo] ddoo, and no I didn't fix the npdrm algo, that's what I'm missing (hence the "kind of") but I'm not
working on that, that's someone else's job
[middleman] gonna debut it at ccc kakaroto or before?
[KaKaRoTo] ddoo, and even if npdrm signing worked.. how do you install your pkg on an OFW 3.73 ?
[heri] so KaKaRoTo, once the NPDRM algo is fixed, a release will come?
[KaKaRoTo] heri, another missing bit, but once that's fixed, yes
[KaKaRoTo] but I'll probably be off country for the next 2 weeks
[KaKaRoTo] so all work will have to be paused
[heri] oh, fair enough. we can all wait 2 weeks hey we have waited months anyways
[KaKaRoTo] ddoo, that might work.. you could also just install your pkg on 3.55 then upgrade
[KaKaRoTo] ddoo, upgrading doesn't delete any of your packages
[KaKaRoTo] ddoo, issue is, you're lost if you didn't do it before upgrading
[ddoo] but they fail because the npdrm algo is spoted by the checks in 3.56+
[KaKaRoTo] heri, also note, I "announced" it because I was excited to see it work as expected
[KaKaRoTo] doesn't mean it's ready for release
[KaKaRoTo] ddoo, exactly
[heri] yeh thats what we were saying just before you came
[KaKaRoTo] so you need : 1 - npdrm algo fixed, 2 - a way to install stuff
[heri] you only announce when you are confident it works
[KaKaRoTo] 1 has been done by someone else (don't know if he'll share it), and 2.. well, I just did it
[KaKaRoTo] heri, well, I was testing on 3.60 and it worked, but yes, I did upgrade to 3.73 to test that it still
works just to make sure I don't tweet any false hopes
[middleman] but you cant run what you installed until 1 is fixed correct?
[KaKaRoTo] middleman, exactly
[middleman] interesting
[docpaul] nice, thx KaKaRoTo
* KaKaRoTo needs to hide now if he wants to get any work done
[KaKaRoTo] ttyl

In summary, KaKaRoToKS upcoming PS3 3.73 Firmware JailBreak will be able to install homebrew .PKG files but unfortunately PlayStation 3 backup managers will not work as they require lv1/lv2 patches that won't be included.

From ps3devwiki.com/index.php?title=KaKaRoTo_Kind_of_%C2%B4Jailbreak%C2%B4#Q.26A:

KaKaRoTo PS3 JailBreak Q&A

Q: Will I need special hardware (e.g. flasher, dongle, modchip etc.)?
A: No.

Q: Will homebrew work?
A: With NPDRM fixed, yes. Showtime would certainly be possible.

Q: Will recent games play correct?
A: Yes, its 3.7x, sure it plays all 1.00 - 3.7x games.

Q: Will PSN work?
A: Yes, its 3.7x, sure goes online without problems.

Q: Does it have Peek & Poke?
A: No. Peek & Poke require modifying lv1 and lv2.

Q: Do Backup manangers (e.g. MultiMAN, Rogero etc.) work?
A: No, see previously answer about Peek & Poke.

Q: Will my old homebrew still work?
A: No. All homebrew need the fixed NPDRM. Homebrew that relies on specific other patched functions/syscalls (e.g. Peek&Poke, BDemu etc.) will not work either, see previously answer about Peek & Poke.

Q: Does it gets us keys?
A: No.

Q: Does it gets us "CFW"/MFW?
A: No.

Q: Does OtherOS++ (Linux/FreeBSD) work?
A: No. Sony removed OtherOS feature after 3.15 and OtherOS++ relies on modifying the firmware. See previous "CFW"/MFW question.

Q: Will it allow downgrade?
A: No.

Q: Does it work on all PS3 models?
A: Yes. all current models.

Q: Are there brick risks?
A: No (standard disclaimer: It will be tested rigorously before release as you can expect from anything that KaKaRoTo has put his name on).

Q: Will this only work on 3.7x?
A: No. It was pretested on 3.60 and again confirmed on 3.73 before any public Tweet about it.

Q: What if Sony releases 3.74/3.80 before release
A: In that case it will be pretested on that version.

Q: So why are all the newssites hyping this that it does give CFW?
A: Because they don't read wiki's/blog's xD Besides, every minor news gets 'prolly CFW soon!' tagged by the bad ones.

Q: Is there a release date?
A: No, besides KaKaRoTo not able to work on it for 2 weeks, it also relies on (other people) fixing NPDRM.

The Road beyond... (or what can you and others do to expand the useability of it)

What is missing Prerelease (current state)?

Fixing NPDRM

  • Make PKG's install and run the SELFs.

What is missing after release?

Peek & Poke

  • lv1/lv2 dumping/patching
  • Payloader3
  • Backup Managers

Downgrade (already possible with Hardware flashing.

  • 3.56+ keys / lv0 decrypted dump
  • Modifying firmware files
  • OtherOS++

Finally, from [Register or Login to view links] he states the following in attempt to clear things up:

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 create_cfw.sh 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.

I agree about the past. But today Sony is what i wrote.

They are on DMCA mode , for everything. They sent a DMCA to Gary Wayne Bowser (aka Garyopa) too, just because his website was hosting some OFW and CFW, go figure what kind of trash is now this company people daily support buying their products. Look the last EULA. THEIR product now is untouchable. For the reasons you wrote, agree. Their image was damaged. They lost and every day are at risk of losing contracts, and games could disappear. Looking the last big fails of this company, with PSPGO and now PSVITA, if they lose their face a spit more, Sony can fail.

You know what? They will not shrink. Devs will, a lawyer and it's done. Do you remember that guy who was going to release a new PSN method for go online? Guess what happened to him.. Noone saw his release, we just saw his life gone. I admire your work. Just be sure nothing will happen to both of you. Losing both of you, this scene will not be struck. Will just disappear. And what will remain will be just a commercial dongle..

I have to clarify a missunderstood of me. Nabnab didn't take to kaka he just have read his post that shows on twitter and that kakarotoks have a debug console which was a retail one befrore.

Not that some one spread this on the web and produce a new drama with it. We dono need more drama's. We all in scene need to calm done a bit and try to make this scene good again

Actually Sony never complaining about any hack/piracy if you check it correctly, it's just a different think happen on the PS3, it's because with some monster ego dev and weird PS3 users, the people claim, it was easy to hack the PS3 (when is not, all come from internal Sony stuff) so badly, download games and insult the Sony company.

On a way, i can understand Sony, because they didn't really attack any users or dev on the PSone/PS2/PSP, when i see some people claim Geohot do so good stuff, i was claiming he does completely the inverse of what i real dev will do... when you a dev/hacker like that, you never claim something from that way and all what Geohot did, it was a completely a mistake.

He didn't find anything => the stuff was from the past and it was a surprise for him that the PS3 have a PPC and that you need to code in C (he had a PS3 and don't know it), just to clarify something, ok it's intelligent but he never find any exploit on Apple product or any Sony product, it was not him, it was other dev that find exploit and use work from other to be in the top of everything, he release stuff that not supposed to be release => need to ask the owner before it.

Just do a small research of PS3 scene, Geohot etc... he make the piracy/hack a f.... commercial and every he claim he can push out Sony before they do this action.

Have a misunderstood about the Sony Action, i don't defend Sony for other stuff they made but it's clearly a misunderstood, Why Sony do this ? it's because of all the pub/insult they have received from the PS3 Scene, touching too much the company, etc... also they didn't give warning to the PS3 users but to the guy who claimed so much stuff that he did not.

Remember that Sony = Company, they need to make money but have also human person who work, they can be fired just for that... take the place of the worker who work in here, if you want to hack, do piracy, it's your problem, you can do it but i never seen in my life a person who claimed like Geohot or some people that they did something like that to make only piss off Sony.

I check the past and i see no action from Sony, just try to make the product better
I check the past and i see no action from Microsoft (only ban, so ?) also if you check how much Windows was pirated, Microsoft don't really care, this make good pub for the company
I check the past and i see no action from Nintendo (only try to stop the card) but they have reason, did you see the peace of crap R4, etc ?...

I mean come on, don't be paranoia, they didn't have really action from any company to a person, the only think about it was for people who make money with stuff that is free and also some mistake

I don't support the company that close the product like that but it's also a challenge for the dev/hacker that make sense but apparently we lost all that and it's more about make money with free stuff and be famour to be on every web tv channel etc...

Who talked about it when you have actually a PS3 completely open with a CFW (do you imagine that we can do everything we want) and also who talk about ECDSA ? Kakarotoks said the way he find to make a HEN was not possible because of that but he didn't say all
and also said he don't want to waste the time... but anyway why you talk about him in here ?

and why waste that much time on that than work on something else, if you try to stop some of the work, you waste your time.
i already showed that we can do something on 4.0 and i don't need any keys for that, have already the tool, source and everything.

Kakaro said it would take an eternity to brute force it, even with a huge team (he said something like 4000 peoples everyday ?).
Forget it, you can't brute ECDS ....

Hopefully it will be hacked one day, but not soon ..
