Bueno pues lo que se está cociendo en psx-scene es el nuevo dispositivo llamado Beagle USB 480 Protocol Analyzer, el cual con la ayuda de un software especial logra dumpear el hex que tiene el PS Downgrade al bajar la version de firmware de la ps3 estando de 3.50 a 3.41 tambien cuelgo un video con el cacharro en uso. Ire actualizando la informacion.
Hansi a long-time valued member of PSX-SCENE has spent huge chunk of his personal money, in buying a very special USB Analyzer called the Beagle!
In his first day of playing around this new wonderful toy of his, he used it of course to make a dump of the normal PS3KEY boot-up and later on which is the main reason for all this fancy hardware the PSDowngrade
PSDowngrade / Ps3 jig USB traffic protocol scan
Hardware Used: Beagle USB 480 Protocol Analyzer Support - Total Phase
You need to use Beagle Data Center Software to be able to read the attached dumps.
One file is a normal PS3KEY boot, the other is a PSDowngrade boot.
The PSDowngrade is supposed to be encrypted and NOT analyzeable according to a distributor!
But maybe something can be learned anyway.
Have fun!
Hopefully some good things will come out of this in a few days by our many talented payload developers we have right here on PSX-SCENE!
Our many thanks to Hansi for spending his hard-earned cash on this project and helping out everyone!
EN ESPAÑOL:
PSDowngrade / Jig Ps3 USB protocolo de análisis de tráfico
Hardware: el USB Beagle 480 Apoyo Analizador de Protocolo - Fase Total
Se necesita utilizar
Beagle Data Center Software para poder leer el dumpeo adjunto.
Uno de los archivos es un boot de PS3KEY normal, el otro es el boot de arranque de PSDowngrade.
El PSDowngrade se supone que esta encriptado y no es analizable de acuerdo con un distribuidor!
Pero tal vez algo se puede aprender de todos modos.
Que se diviertan!
Un usuario les preguntó en su video en youtube que como lograron acceder al service mode de la consolaEl dueño del video les respondió:
Re-read the video description. We used a psjailbreak re-programmed with the psdowngrade "one-time-only" downgrader. The blue "beagle" box was just used to take a look at the USB data between the PS3 and the psdowngrade.
From what I understand, you cant just use the USB data we scanned to reproduce the psdowngrade behaviour. There is a challenge response protocol, meaning that the data "talk" between the dongle and the ps3 will always be different.
