Behold the greatness of JFW DH 3.56 MA, an CFW that you most likely want to check out.. There is no doubt that JaiCrab along with Hermes as one of those Spanish developers that actually did some work unlike others who only knows how to talk. So, what exactly is JFW DH 3.56 MA you say? Let’s see a detailed specifications of the solid...

This is being reported as a fake, as I said I haven’t tried it so am unable to confirm either way. It is probably best for users to ignore for now and wait for Project PROGSKEET to become retail or go the infectus route.

Thanks to user Guest_1651 I bring you (pre 17th Feb 2009) PS3 owners good news. Clever so and so’s at thetechgame.com have found a way to downgrade PS3′s (made before the 17th February 2009) to OFW 3.21, meaning of course where you go from there is entirely up to you (REBUG anybody?)

The method is pretty long winded and will NOT, currently work on PS3′s made AFTER February 17th 2009 (did I mention that already?), also the only “registration codes” (the code that corresponds to the firmware you want to end up on) made public at the moment are for phats but slim ones are available by PM’ing the author of the original forum post here.

There are some issues to take in mind first though:

You need 2 wireless controllers and cables for each

You need 2 4gb (NO SMALLER) usb sticks

You need a CD or old game (they don’t say how old but I’m guessing the older the better, or just stick to your bon jovi best of album)

You probably want someone with you, to keep pressing O, and call an ambulance when your heart gives out from the stress of possibly killing your lovely PS3.

I haven’t tried it myself as I’m still on 3.51 but from other members of thetechgame.com it seems to work.

I’m not going to post the tutorial here as I figure if you can’t even find the link to it above you will no doubt screw your PS3 up :p

If any of you guys try it please let us know how it goes, and follow the instructions to the T.

After their announcement of the 3.56+ firmware exploit discovery, Gitbrew’s fame has rose to the top and it shows to how many Twitter users followed their account now compared to several weeks ago.

Well, let me took the liberty to showcase some of Gitbrew’s progress update with their Q&A tweets where you can get an idea to how much the work has went into exploiting the exploit now as well as more information about it.

So, from what i can read, Gitbrew team has sent their “theory” to a set of developers and that the exploit derived from ps3dm-utils / tools which we all know is from graf_chokolo’s work.

@gitbrew for the ps3, did u find the possible exploit?
Yes the theory was done by us, but will be performed by a different set of individuals. We will update on it’s progress tho.

@gitbrew decrypted?
Encrypted, we have a few theories on how to get the rootkey since it’s called in lv1 and lv2. R/W to lpars = <3

@gitbrew You’re going to tear it wide open aren’t you ?
It already is. Not many people have done the research on what ps3dm-utils / tools can do for the ps3.

@gitbrew well, we was thinking decrypted :p isn’t asecure_ldr decrypted by hw? bootldr/metldr and lv0 can be found in ram, but cell key…
each time any of the ldrs is loaded, it gets sent to the ppu and done internally. Attach a few things / edit a few things and bam.

@gitbrew Dude congratulation for this great news dumping bootloader, but i wanna know yr sugges time for realase date for cfw 3.56
We have given the exploit off to another team to work on it. We’re not allowed to say atm, but they’re going to be working soon.

@gitbrew @UberHaxorJr Is with it will be possible also downgrade from 3.56?
Not at the moment. The exploit COULD lead to a downgrade, but developers would need to figure that out as well.

@gitbrew is that good? Is it a hardware exploit or FW exploit. (will it be patched in later FW’s)
Im not at liberty to dicuss if it’s a hardware or firmware exploit. All in due time.

@gitbrew just to clarify, you seek the root key to get to lv0 and then somehow get to the keys. I don’t have a real clue, pls answer.
We seek the root key for dumping of everything else for that console. (Makes it easier, much easier).

I do hope that this exploit would work for a 3.61 CFW or maybe we can call as a 3.66 CFW too. Let’s just wait and see.

UPDATE:

About the key questions. 3.55 and below = rev 1, 3.56+ = rev 2. Public = decrypt, Private = Encrypt. We do not have rev 2 keys. That is all.

I’m sure you are familiar with the gitbrew guys who has brought you OtherOS++ as well as other PS3 tweaks that are in line with the Linux thing. Well, they may have to put that project aside now after they have discovered a theory which would work with the 3.56+ exploit that everyone has been craving about for the past few..months.

Interesting… Have a theory for a new exploit for 3.56+. Testing it in a bit.

If they indeed found the real thing, and release it in the latest CFW form, I’m sure everyone will kiss their ass thanked them for the effort they’ve done to help the scene. Good luck gitbrew team!

I have no idea what the end users can benefit with the debug PS3 firmwares because we already knew folks at Rebug got most of the debug functions up and running in their custom firmwares (CFW).

I know debug PS3s though, the consoles was a rare and its been tailored for someone with deep programming knowledge who wants to test things on their PS3 development project, mostly the game studios. But, in the recent years, George Hotz and Mathieulh claimed they owned the debug systems which help in part to their hacking activity. Mind you, the cost of one debug unit is in the region of $10,000 dollars according to what i stumbled upon in the net.

The console exterior look are not much different than the retail ones, except the “Test” word. See it below.

If you are still interested to check out the debug firmwares, you know, to see how it looks like, then, here you go.
