Hi,

I don't want to do a mod or admin's job, but I'd just ask you to read that before posting. I'll try to recap things that couldn't possibly work. DO NOT make a new thread about these things -- they have been discussed before and people were flamed. I just want to avoid this.
  • Bunnie is not the answer: He helped a lot for the first Xbox, but he said he wouldn't touch the 360. Maybe because he signed something with MS, to stop his acting. We don't know, and he won't say.
  • About the signatures: You can't sign a XEX file. We weren't able to sign them on the first Xbox. If we wanted to sign our homebrew stuff, we would need the private key. MS has it, on a computer in a secured vault, disconnected from the network (we're not sure of course, but I think they'd have to do that). Maybe 2 people are allowed to touch the machine. It won't happen. Also, we can't bruteforce the key! It would be way too long. You can even be pretty sure that we couldn't find the key. Not even in our lifespan.
  • Stripping the signature/the media check: If you touch the file, you're done. But if the media check fails too, you're screwed. I don't think we can go this way.
  • D0 Point/LPC Bus: The LPC Bus exists, but there's no actual way to exploit it. Maybe in the future it will be the way, once again, to "hack" the box. But not yet.
  • More about the hypervisor: From what I understood, the hypervisor is activated in the boot sequence. We can't decrypt the whole thing yet. If we can, maybe it could be done.
  • Softmods?: Not yet. Or maybe never, because of the hypervisor.
  • Xbox 1 backup working?: MS wouldn't be dumb enough to let backups of old Xbox games work. Those are rumors.
  • Exploiting bugs through Backwards Compatibility?: The emulator is running in a sandbox, and still checked by the hypervisor. Also, you can't use your old savegames on the Xbox 360.
  • Inject data through Live! connection?: No. The data link is encrypted too.
  • "ZOMG liek, letz dump teh BIOS and Xecuter will do wicked stuff wit it": Stop this kind of posts. We're trying to investigate on real paths, and we don't need this kind of posts. Thank you.
  • "MY FREIEND CRAXORED TEH XBOX, HE WONT TELL U YET BUT ULL SEE SOON": Proof? By proof I mean schemes, detailed operation, photos of all the process, and eventually a video of you playing backups. No cuts in the video, and we want to see all the wires exposed, from the 360 to the TV, including the controller cable.
Of course, this list is non-exhaustive. You can add things by replying, and I'll update the list.

For the own good of this community, try to avoid this kind of posts. If you have something useful to make us go forward, we'll listen to you. But suggesting solutions that worked for the old Xbox isn't helping. We know you're trying to help, but please read this first.

Enjoy your stay, and be constructive smile.gif

EDIT: Just saw that heinrich posted guidelines too... Ah well, felt like I was a little more detailed.

How about no Posting about clustering xboxes or computers to brute force the keys?
This has been talked about and yet I saw another recent post on the same subject. From my understanding, doing it this way, we would eventually get the key.....but not in our lifetime.

Actually....not in the universes lifetime if we used all the computing power on earth as of right now. If we harnessed the power of the sun....and used it to power modern computers...it still wouldn't be enough to check 1% of the possible numbers.

same as abvoe (no, media type is not the same as bitsetting)

gotta have peopel who have nothign better to do than spread stupid rumors

QUOTE
Exploiting bugs through Backwards Compatibility?

best we can hope for here is to emulate a modded xbox, not modding 360, plus the emualtion program is very game-specific, more then likely any of our homebrew code will simply crash the emulator

im sure they could, trouble isnt hacking the bios, trouble is getting the hacked bios loaded into memory where it can actually do some good

good for your friend, so why isnt he posting this?



well that sums up my form responses to these kinds of people, nice post, we need to get more folks like you in here, thin out the uber-1337 hax0r kiddies a bit

If you're keeping a list, I want to be on it. Even the much smaller RSA keys would require many, many years to factor, and I understand just enough maths to be aware of how much the scale of the project increases. Prime numbers really suck, from a programming point of view.

If it gets stickied maybe a mod would add your extra bits to it, or you could post an updated version which would become the sticky. PM a Head Mod like Chancer or Mr. Ed, or possibly the admin, HSDEMONZ.
