Sony PlayStation 3 Hacker KaKaRoToKS JailBreaks 3.73 PS3 FW?


Sponsored Links
158w 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.

It's more for the dev who want to be more interested by bypassing the ECDSA -> using timing attack
also TLS - > transport layer security, you can see that on PS3swu include TLS for the update of firmware.

LOAD->TLS->LOOS1

Apparently you don't want to understand ? if some people keep stuff and just share without put that every on the web, we probably don't see that coming but also keep in mind that the world try to do better and better, today have DMCA, tomorrow have other things, DMCA it's just a moment to take... in the past we didn't have internet, today we have, tomorrow we can have better possibility to share, etc...

Sony didn't fail, it's the scene fail in here, also whatever they send a DMCA to Gary Wayne Bowser (aka GaryOpa) hosting some OFW/CFW so ? i think is more related to the dongle, don't think ?...

Sony never obliged anyone to buy their product and not even Apple, you know that Apple is more strict and more spying you than Sony ?... the iPhone is certainly the baddest phone i ever seen, i prefer a good nokia than i bad Apple

i use personally a iMac because of the resolution and to save some place, for some product it's good for other is bad, look what happen if the people complaining, Apple made bootcamp to support Windows (it's probably because of the help of Microsoft in the past)

I don't think Sony is that bad but it's probably doing what they think is better for the company, how much money they lost ?...

Nothin will happen to me in this way, i don't make real problem for Sony... i was already complaining about the stuff they made, like SDK Open suite that don't support Linux/Mac OS and they don't give any good support to help to the indie dev, etc...

For the PS Vita, it's different we are not obliged to use CMA...

I don't remember anything about the guy who was going to release a PSN Method but it's also doesn't make any sense, you choose like on the XBOX live, you want to keep the PS3/XBOX like that keep but don't ask too much

nobody have a life gone lol.. .and where you saw that the dev was really sued ? all is more theory/fail comment, don't take too seriously all you read on internet, stuff can be true, like they can be lie.
