We have the PSJailbreak dongle yet again brought out of retirement to put it more precisely Herbs to take a closer look. We tell you here in brief the main steps of the internal process of PSJailbreak.
We 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 überschriebt 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 (we are moving here in Milisekundenbereich) the jig module is connected, and encrypted data are transmitted to the module jig. A (in Milisekundenbereich) 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.
