Sony PlayStation 3 Hacker KaKaRoToKS JailBreaks 3.73 PS3 FW?


Sponsored Links
144w 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.

The scene isn't dead it is stuck. I know from some underground dev on what they are working on but i have no permission to call it here. One big problem the ps3 scene have is to hint information. Nabnab talked to kaka via twitter about turning a 4.0 ps3 into a full debug one and guess what ? Kakaroto knows that !!!

Yea sure and what about the 360 scene ? Is C4E (hail to you man) not working on piracy stuff ? Or all others they have made backups and a hacked con eg via gligli possible not working on piracy ?

The so called dev's in ps3 scene seems to have the EGO HOT syndrome. Hinting infos for them an not give out to the scene. Some one said they are afraid of that sony will patch the possibility of using the debugger as a mode for games and among other stuff when they release. Does the average user really believe this ?

Hell sony have developed this sys and know better then some one else in this stuck scene how it make those games work. So why hinting this infos ? = EGO HOT syndrome. Just to have it for them self and laughing about the scene or just for them self and how good they are.

I can't really say whats the reason for but for sure not in case of being afraid off that sony will patch it. If they want to patch then they do and not in case of it gets public released.

They patched things in past without something useable was released. Also nabnab got a message from some one not to be called here that he should stop his work. Yea sure we will stop only in case of this person tell us/him to do so.

On some points a lot of dev's in the ps3 scene think they are god's or better then the average user. We are all the same it's not a matter of the color of your skin and also it's not a matter if you're a normal user or a hacker or a coder, scriptor, modder or what ever.

We all deserve the same and no one have the right's to milk some one other with stuff that should be free.

Hail to grafchockolo and shame to the one that use his work to milk the average user and also shame to all others that hinting informations.

Hail.. Was it useful for a progress? Culturally talking, amazing to read. But.... So? What he meant is "scene is dead, if you're a dev feel free to go M$" or what?

I didn't judge KaKaRoToKS, i said maybe that he have the own reason to stop, i don't want to judge him or anyone else but too much PS3 users want to see the new keys etc... and it's not the only way to exploit the PS3 and have also better alternative and more interesting when you know that we don't need this keys... the PS3 Scene have more tools and more information about the PS3 than the XBOX/Wii Scene...

I know that i repeat many times Graf offer big stuff about the PS3, the only one who was thinking release public the work (a person recently contact me to tell me some interesting stuff about PS3dev wiki and other dev on the PS3 scene, that they like to keep secret or share work from other), even Sony offer the best door to exploit the PS3 but it look like that some devs prefer to make business with free stuff and after we ask why Sony make some bad action (actually i didn't see anyone going to the jail and it would never happen for that)

I know it's so annoying to wait something you are waiting for a long time but unfortunately some dev don't know the definition share and like to make business with that, also they make crappy code or steal code from other dev that share for free and put on a dongle with stupid drm to hide the crappy work and scared to see the PS3 users complaining about that.

You know i stop some my work not related to the PS3, just to come give help and i saw the last few weeks many insult from the PS3 users and even the PS Vita users lol, also see some dev good lie to distract the PS3 users and said don't trust him to hide the real information from different website of the PS3 hack, i saw some website respectful and other website that judge a person they don't even know and try to make some fire for nothing...

The Truth Behind the Lie

I always try to do my best to help people on the PC community, i make alternative driver, patch for games, mods... many of this work was released for free and i was working alone on it, i received so many thanks than i didn't expected that much and also some good insult... but the world is like that and you can't change it, you can make it better but don't change it .

I keep working and let you know all what i'm trying to do.
