Endless Paradigm

The guys at GameFreax have managed to 'reverse engineer' PSJailbreak and the most interesting discovery is that it is far more than a clone of Sony's repair property. According to reports, it is a self-made exploit by the team which will be sure to surprise a whole lot of people. The technical break-down also gives some great insight into how it all functions. Although in another 'shock', the analysis seems to indicate that the product won't allow users to update it unless they have some special hardware.

And even more info:

Quote:Wee have the dongle PSJailbreak yet again brought out of retirement to put it more precisely Herbs to take a closer look. Wee tell you here in brief the main steps of the internal process of PSJailbreak.

Wee can confirm that it can not confirm that PSJailbreak a clone of Sony's "Jig" is module.  PSJailbrak is an exploit honest self-developed.  The chip is not but a PIC18F444 ATMega with software USB.  This means the chip is internally capable of USB to emulate.

PSJailbreak mainly be emulated 6Port a USB hub connected to a specific end USB devices and then disconnected.  One of these devices has the ID of Sony's "Jig" module, which means that played in the development of PSJailbreaks the "Jig" module, a certain role.

But let's start at the front: When the PS3 is clamped in the USB emulation device, which has a much too big Configuration Descriptor.  This Descriptor the stack with a PowerPC contained code that is executed.  Now, various USB devices are connected in the emulation.  A device has a large 0xAD Descriptor, which is part of the exploit and contains static data.  A short time later the jig module is connected, and encrypted data are transmitted to the module jig.  A  eternity later, the answers Jig 64Byte module with static data, all USB devices are disconnected, a new USB device is connected and the PS3 launches with a new look.

Incidentally PSJailbreak is NOT updateable. The Update feature can be mentioned, if realized at all, only with additional hardware.

So does this mean that they are able to make any old shmuck usb device work?

Then again, "emulating" the USB Jig stick probably takes special hardware, i don't know @_@

No. The PSJailbreak is not a standard USB stick. The PIC18F444 chip that it uses is basically a small self contained computer. It can be programed to do pretty much anything. In this case it's programmed to emulate a series of specialist Sony devices being connected and disconnected.

Well I bet PSP Homebrew could achieve the same...

Now there's a thought...
