    a mear 4 months after the launch of the 360 and the infamous quote

    "There are going to be Levels of security in this box that the hacker community has never seen before"

    Chris Satchell, Team Xbox

    a team of dedicated hackers have gotten DVD-R copies of 360 games to play on a 360. In addition they are not releasing the firmware to do this as it can only be used for Piricy and not homebrew. (Good for them!) This does open the doors for the type of homebrew scene that the original Xbox enjoys.


    >> As you know TheSpecialist and his team were working on a modified firmware for the Xbox 360. He already managed to make one for the original Xbox a while ago, and he announced this method was highly likely possible with the Xbox 360 too. From TheSpecialist on xboxhacker.net:
    What is this? A bit more info...
    The hack is a modified firmware of the Xbox 360 Hitachi-LG GDR-3120L DVD-ROM drive (the security in the Toshiba/Samsung TS-H943 is said to be similar, so it's probably also possible with this drive ... but it does require it's own hacked firmware of course).
    As you (should) know, all Xbox 360 executables (XEX files) are signed by Microsoft (with a private key only MS has). This means that if you try to change anything to the XEX file, the signature will be wrong and the file will not boot.
    Now ... to protect from booting an exact copy of a game from a DVD-R or other recordable media, microsoft gave each XEX file a 'mediaflag'. This mediaflag tells the Xbox 360 from which media (cd-r, dvd-r, dvd+r, dvd-rw, hdd, dvdxbox, dvdxbox360, ...) the XEX is allowed to boot. Changing this mediaflag in the XEX header is not an option as it'll break the signature of the file (see above), so ... what's done in this firmware hack is 'break' the detection of the disc.
    Retail games usually get a mediaflag where they only allow 'dvdxbox360' (Xbox 360 discs - different than a normal DVD because it has some specific bad sectors and special info in lead-in/out that can't be written with a standard dvd burner). The modified firmware will trick the DVD drive into reporting a DVD-R (or other) as a DVDXBOX360 to the Xbox 360.

    How can you do this?
    Well, right now you can't. The firmware has not been released to the public because it would mostly be used for piracy and that's not what this team wants (unlike the original Xbox hack this can't be used (atleast not directly) for homebrew and linux fun). But the research done by these guys is public as you can read their discussions of the last few months on the xboxhacker.net forums, so people with good assembly experience should be able to duplicate this hack.

    If the firmware was released, what would it mean?
    Right now the Xbox 360 DVD firmware can't be flashed via PC (and for us, end-users, even less directly by the Xbox 360 itself (Microsoft could probably flash the drive from Xbox360 tho)), because there's no software to do this. Of course, drivers and flashing software for Xbox360 DVD drives could probably be written (and some people have been working on this), but so far this has not been done (atleast not publicly).
    So, that means you'd have to open your Xbox 360, open your DVD drive and desolder the chip where the firmware is stored on.
    Each Xbox 360 DVD drive has a unique key, if that key doesn't match what your console is expecting your DVD drive will not work.
    So next you will need to read your current firmware chip with special hardware (flash programmer), to find your unique DVD 16 byte key (stored at 0x4F00). Then you'll have to insert this key in the modified firmware (or patch your original firmware) and program this modified firmware back on the firmware chip. Then put the firmware chip back in the drive, close DVD drive and Xbox 360 and I guess you're done.
    As said above the hack would allow you to run MS-signed and unmodified XEX files only, so that also means the game must be of right region (as changing the regionflag in the XEX header would break the signature). Unsigned, homebrew executables would of course not work, again because signature check would fail.

    LIVE and Updates ...
    Can you go on LIVE with this hack? Well the firmware isn't released, so noone can try, but I'd guess it would work yes. The Xbox 360 itself is fully in 'normal state', nothing is modified to the Xbox 360 itself, it just gets 'wrong' info from the DVD drive. Of course if you start modifying non-signed files (like textures, ini files, ...) in order to cheat on LIVE or so MS could easily check for that.
    Can Microsoft stop this firmware hack with forced LIVE updates? They could probably try detect a basic modified DVD firmware, but anything the Xbox 360 asks to the DVD drive goes via the DVD firmware, and if the firmware is 'open' in the hands of the hackers the firmware can probably each time be modified again to give the reply to the console expects. Microsoft could maybe do more with a HW security update ... but I'll let them analyse that.

    (Note that all info above is based on all stuff I read ... if I made any mistakes, let me know)
    (This news post will be updated often with more info/details, so keep checking if you're interested)

    ^ Thats what everyone in the world thought when Chris Satchell said that. Nice to see that its been busted now. :thumbs2:  I wonder what homebrew will come of this..

    Now I'd really love to see HD-DVD and Blu-Ray players get busted so that people who bought HDTVs back in the day can watch true HD content and not be screwed by hollywood and HDMI.

    It's only a matter of time before the firmware is leaked or the other files are hacked and cheating on Live will be rampant. Great.

    Did you read the article?


    This has nothing to do with cheating on Live, and in the history of live cheating has been delt with quickly. You see the servers are all in Microsofts hands and as a result someone may find a way to cheat but it's been shut down fast in the past and I have no doubt that it will be in the future.

    The biggest thing with the Xbox scene is that the people behind the hacking are respectful in the way that they do not support piracy in what they do, they are trying to find ways to make homebrew apps for the system and if companies would embrace these people instead of trying to harass them their work would not lead to the piracy side effect that happens, but no they fight and hinder them, until they succede and then they hire them.

    I thought, as Halo 2 is most mentioned, cheating had become a problem on Live? (Along with the high number of asshats)

    Cheating is a problem on Halo 2 because it attracted the largest number of users and the largest number of potential modders. as it stands, microsoft has done a tremendous amount to stop cheaters.

    this is not to say they don't still pop up and we don't all get upset, but all you have to do is report them...
