February 5, 2012 // 8:37 pm - Following up on the previous update, this weekend PlayStation 3 homebrew development group DexL0ve have made available a PS3 patched DEX LV2_Kernel.Self for CEX consoles followed by a revision below that fixes PS3 crashing issues.

Download: PS3 Patched DEX LV2_Kernel.Self for CEX Consoles / PS3 Patched DEX LV2_Kernel.Self for CEX Consoles (Mirror) / PS3 Patched DEX LV2_Kernel.Self for CEX Consoles (Fixed)

Essentially this PKG release is a patched LV2 DEX (Debug / Test) kernel for CEX (Retail) PS3 consoles based on the recent LV2 Loader release.

To quote: From my limited understanding of PS3 coding and reading the NFO file, that by using the LV2_Loader released by Team Rebug earlier, and by QA flag'ing your CEX machine, this file is basically a patched LV2 DEX kernel that will load fully on your CEX machine and thereby give you some DEX (aka) TEST machine L0VE on your Jailbroken PS3 Console.

From Cyberskunk: Syscall 8, 9, 10 are broken in this lv2_kernel.self. The patch for 3.55 CEX lv2 has been used which ends up point to the wrong offset. The kernel will still work but if an app calls those syscalls the PS3 will crash. Hopefully it was just a mistake and they will fix it..

Finally, from the included PS3 NFO File:

I'm sorry but I have to reply... sorry for the OT. DUDE!!!! did you ask to you why Sony remove OtherOS ? which his the person that cause that ? Sony KNOW VERY WELL that if OTHEROS was still inside the PS3 GAMEOS also the 9.99 firmware could be hacked.... without Geohot and the study coming after, psjailbreak NEVER HIT the market.

is too simple find a USB buffer overflow when a exploit is released and give to you access to the ENTIRE system and last question for YOU... WHO obtain the keys of the system ? something that everyone says is impossible is impossible is impossible... Santa Claus ?

My apologize AGAIN for the OT...

You were saying someone was wrong, when they were not. I was being calm and I was only stating facts. The JIG Sony uses, is an intentional backdoor for administration purposes.

The first Jailbreak, exploited a bug in how the PS3 handles connected USB devices, after a precedure bugging/glitching, the Jailbreak device gets read and write access to the ram.

But I'll let the this explain ( The JIG just tells the PS3 to enter Factory Service Mode, there is no ".self" on a JIG which launches Factory Service Mode.

ps3en i know plz calm down. The first Jailbreak stick was a modded clone of sonys official JIG there for it is called JIG not that i meant sonys official JIG. Oh Boy

They used the master key and the method aka backdore that sony use with the JIG to inject a factory service mode self for injecting a payload to allow homebrew and all that stuff.

As far as I know, this what happens on PS3 scene last 2010:

  • PSJailbreak was announced around August 17 2010. With solid proofs live action feed how it works and such.
  • September 1 2010 PSJailbreak was released with OMFG price of $150.
  • September 10, 2010 PSJailbreak reversed engineered, documented how it works, opensource code and hex codes for development usb jigs released.
  • September 21 , 2010 Sony updates to 3.42, kills PSJailbreak
  • October 2010 PSjailbreak downgrade announced/released.
  • November 2010 opensource downgrade jig reversed engineered, released opensource, ported to development usb jigs
    December 2010 Fail0verfl0w announced that they totally defeated the PS3's security schema, they call it epic fail.
  • January 2011 GeoHot CFW released, NPDRM 3.55 defeated. Allows user to sign their own application on PS3 using the ECDSA bug. Private and Public Keys released.
  • February 2011 Rebug CFW released. Allows users to login on Developers PSN network. Allows user to fake credits and buy stuff on PSN for free (no credit card fraud happens) [that was really good, it lasted for about 3 months before they patched it]
  • April 2011 PSN got hacked, more than 10million user account got hacked. Nice!
  • August 2011, PSN resumed, they took long enough.

No the first usable Jailbreak was not Sony's factory service mode JIG. The first 'usable' jailbreak was a USB device, which in a nutshell, pretended to be a USB hub and glitched the PS3 FW and modified the ram, patching lv2 allowing for peek and poke.

Of course it is more complicated than that, go watch team failoverflow's CCC presentation if you want to learn more about the 3.41 OFW Jailbreak, they have a segment where they explain the crux it. The JIG, is used by Sony to service PS3's by giving special access, but it doesn't allow the user to run unsigned code or game backups.

miandad, no they don't work it's a full debug fw and thoes also don't work on a retail without converting to a dex machine.

No really ? So it wasn't the JIG who enabled Homebrew and game backups ? Geohot gived that to the scene ? Also it wasn't failoverflow who released some keys first and after that egohot also released something just to say "Hey look at me im so good" ?

And by the way his Hardware exploit don't work without linux and you can't clitch the RAM under GameOS. Also he has released nothing from this files he dumped. So what.

And to correct myself it's not a 3.72 SDG (how they called it) it's a 3.74.

and 1 more thing does special downgrade pup's work with retail pup 3.60+ to downgrade without any tools! if yes how?
