EEPROM on Xbox 360 and xexdump utility-- Posted by XanTium on December 2 03:20 EST
XboxHacker/Free60 pointed out there's a Atmel EEPROM on the Xbox 360 near the CPU:

There is also a small flash chip near the CPU, as seen in these pictures:
* 1stgame article (probably a developer unit)
* informit.com article
* independent photo
* Anandtech article

As discussed in this article (by oz_paulb) on the xboxhacker.net forums, this appears to be a Atmel 25020 EEPROM. The chip from the 1stgame article reads:
ATMEL524
25020AN
SU18
Datasheet can be found here[atmel.com]

XboxHacker.net also posted an xexdumper utility (for linux) that was released by oskie on IRC. You can download it here.

So with this said, The eeprom has been dumped? Now we wait for someone to hack the crap out of it or am I just having high hopes?

[Cthulhu32]

Give me some time tomorrow after I finish my web dev class and I can convert Xexdump from PERL to C/C++ (depending on if I need any C++ calls) unless someone else beats me to it.

I'm still trying to get my hands on a 360.  Once I get one, the first thing I'll do is remove both the EEPROM and the NAND flash (TSOP) and dump their contents.

The original Xbox had an EEPROM for per-Xbox settings (serial number, PAL/NTSC, etc).  I imagine the 360 EEPROM serves a similar purpose.  (Although they could have used the NAND for this type of storage)

Here's a win32 version of the app I rolled this morning.  Hope it helps:

You are going to desolder two extremely vital chips from your xbox 360's mainboard , then risk corrupting them by connecting it to an untested hardware config ?

You got balls man  

[unspoiledpuma]

can we extract the data or read only the data??

Thanks for all your hard work.

I'm getting a 500gb drive for my xbox, as far as I'm concerned you breaking the 120gb limit was one of the biggest breakthroughs for the xbox.

Maybe you could post your PayPal addy so people can donate.

Agree
I think by donating xboxs to the hackers, we will reach our goal sooner , I really think the tsop has the dashboard on it, since the core system without hdd can also be updated through live, so the dashboard has to be stored in the TSOP, since there is no other big storage chip on the xbox, if we know more about the dashboard , we can find exploits

Thats one small step for man, one giant leap for hackers!!


JEB!

Wow, that was fast (less than a week from its release and we already can dump x360 executables.  Great job guys!

The program doesn't seem to work for me.  When I open it in command, I get the following error:
"Missing File Argument"

  Does anyone know how to fix this?

have to agree there, aside from getting the xbox to run unsigned code, breaking the 137 gig limit on hdd has to be the second greatest leap on the xbox.

credit due paul (and it turned a simple fix if i remember rightly).



as for donations, i dont think he`ll be into that, anyone remember WAB (PSP).  turned it all into a farce.


but good luck, and thanks to all the clever people out there

in DOS or Command prompt (start/excecute/cmd or command.com)
find the folder with xexdump.exe and the default.xex files
type this command:
xexdump.exe default.xex

actually you will only see what is the structure of the files , but you can have the same result with ollydbg, just rename the default.xex to default.exe and open it with ollydbg.

goodluck

I say good work to all whos tring hard to do this. I hope it works. If it works this would be huge.

[Shutdown[Swe]]

yea, somewhere to donate would be a good progress for hackers to get the needed equipment, ..

But stil we arent sure who is gonna fix it. and maybe we donate ALOT of xxxx$ to someone and he didnt hack it and someone else gets to hack it with no donated money for it. Still the first guy deservse some money but not 4digit cash ^^

Mmmhhh, just buyed a second x360 to make some experiments and in this one there isn't the eeprom near the CPU!!! You can see the empty space here:

(IMG:http://www.darkmoon.org/images/x360Pro_noeeprom.jpg)

The console WITHOUT the eeprom is a "Premium", the one WITH the eeprom is a "Core".
No vital data inside this eeprom for me ;-)
