A german shop whose name is Gamefreak has posted on his blog. I try to translate.

They affirm that the PS JAILBREAK is not a copy of the jig from Sony and a true exploit. By the way are they saying this to make it legal and sell it on their shop? They affirm that the chip is not a PIC18F444 and rather and ATMega chip with Software emulation of USB. They tell that the PSJailbreak emulate roughly a 6 port USB Hub.

In this chip several USB-devices must get connected and disconnected in a speciffic sequence. One of these devices has the ID of Sony´s “Jig” modue. Furthermore they discover that the “Configuration Descriptor” is too big when the SP3 is powered on.

They should have explained that (taken from this site ).

This discriptor overwrites the stack with contained PowerPC-code that is executed. Now various other devices get connected within the emulation. One device has a 0xAD large descriptor that is part of the exploit and contains static data. Short time later (we´re talking about milliseconds here) the “Jig” gets connected and encrypted data is sent to the “Jig”.
An eternity later (in milliseconds that is) the “Jig” answers with 64Bytes of static data, all USB-devices get disconnected, a new device is connected and the PS3 restarts in a new look.

They have a lot of affirmations but no technical proof. And again say that the firmware is not upgradable and publish too an image of what seems to look like a dump of logic analyzer but without any explanation or even the model of the analyzer. And as you may know or not, each ATMEL or other MUC brand can be updated either by the JTAG points available but stucked in the glue of via a simple way through a bootloader (binary executable). For this reason i don’t agree with them. They only need a driver to make it seen by the pc.

Here is a copy of the text you may see on the site of Demonhades, its spanish :

“La web ha sido hackeada nuevamente, subiendo archivos que pueden culpar a DH.Org y al Hosting como responsable de los archivos. Se esta estudiando emprender acciones legales contra los responsables (Decir que tenemos los logs de uso al FTP, asi como las IPs y todos los datos)

Por favor, borrad de las demas Webs la información, ya que nosotros no hemos publicado nada. En caso de que no se borre, se procedera a denunciar dichas Webs por difamación (Entre ellas maxconsole)”

In plain english :

“Our site has been hacked showing archives that may accuse DH.org and the hosting company as responsible of them.We intend to make legal actions against the people responsible of that (we have logs from the FTP, as well as IPs and data).
In no case DH.Org nor anybody of the Staff is the source from this archives. All this was organized by Math, Geo, Bi0h4z4rd and Fidillo.

This a maneuvers because we do not speak and have changed pass of DemonHades on PS3News and blocked MSN. Our Staff recommend not to buy the Jig, as well as not to update to version 3.40.

The pulse of Geo is false, agencio with the Jig and said that he was his. Please, you erase of the other Webs the information, since we have not published anything. In case one does not erase, procedera to denounce these Webs by defamation (Among them maxconsole)”

…”

Well, you will not believeme and think i’m kidding. I was given the ability to study this dongle as “a practical job” on reverse engineering! I didn’t even had to argue! Long live the Royal Institute! I will use my time on this project and have a notation! Ok they do this because they believe in me thought i am not truly a geek. Or perhaps this will act in my favor.

I already have studied the schematics found on the french site and already begun to do a better one with Eagle CAD. This well-known software is perfect for students because there is a free version whose limitations are only the size of PCB and the number of layers. In our case it will enough. If i need more i wan work in the labo with the full version.
