Title: Onboard Flash
Post by: superjedi on November 24, 2005, 07:00:00 AM
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

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...

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.c...?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 It might help explain why your discussion here is somewhat out of date smile.gif
