Hey,

Can anyone try to make a dump of the flash content ?

Here's the technical documentation of the 128MB Flash rom:

We don't have the 360 retailed in Europe yet :-\

Thanks,

No, because that would be illigal and not very nice. Not very nice at all.

I'm sure bunnie will but if he does I hope he doesn't have another close encounter with m$ though like last time they asked him to pull the code of his site.

Hey,

First of all, its a 128 Mb (mega bit) chip. So that would be 16 MB (mega byte) flash drive.

Also, all the data is encrypted w/ a special key that is embedded in the CPU (each xbox has diff key).

I guess it would be hard to decrypt the data w/o the key. But be creative wink.gif

embedded in the cpu we can retrieve that key somehow, have faith brotha!

AND ON TOP OF THE ENCRYPTION IS THE FACT THAT THE HEX CODE ON THE EEPROM IS SPECIFIC TO A CUSTOM PROCESSOR MADE BY IBM. theres a good chance the opcodes between this powerpc processor is not going to match the opcodes to the other powerpc processor...

wow thanks for pee'ing in my cheerios dry.gif

any good news?

I would have to think other wise that the chip would hold the NAND those keys. If nothing else you could use the chip to open and unlock the DVD keys. And Now know the at they used an IBM CPU Power PC it should be easy to find those keys as most people that work for IBM are idiots!

So has anyone tried to JTag these systems yet? Plus Do you really think Microsoft would put that much effort into it? They Just like too sue people! smile.gif LOL.. The Only Problem would be to understand that Xbox 360 chip? wink.gif

The flash has been dumped years ago, it's encrypted with a per-box key but it's been decrypted (the king king exploit on the pre-security-fix dashboards lets you get the cpu key and decrypt all of the flash) and many parts have been disassembled by various smart people. It's a perfectly standard PowerPC and any old PowerPC disassembler can do it just fine.

You appear to be unaware of the last several years of research and hacking effort into the Xbox 360's security system. It is very well designed and has only a few very minor flaws which as yet have not allowed any significant exploits other than the ability to play backups of retail discs and to resign CON containers after modification.

http://www.youtube.com/watch?v=uxjpmc8ZIxM# is an excellent video, a tech talk given by some of the people involved in the research and hacking. It might help explain why your discussion here is somewhat out of date smile.gif
