    Default JTAG/freeBOOT/XBReBOOT FAQ

    JTAG/freeBOOT/XBReboot FAQ

    *Information for this FAQ has been taken from many sources. Most was typed but there are also parts taken from other sources*

    Xbins is mentioned in this FAQ a couple times. Here is the download for it. Code:

    JTAG Hack:


    What is the JTAG Hack?
    This is a new hack which can boot homebrew code in less than 5 seconds. For now, all we need to know is that this is a new way to exploit the well-known 4532 kernel, in a way which also works on updated machines, unless they have been updated by the summer '09 update. It also works on all hardware types.

    What does the JTAG Hack require?
    1. The hack requires a console that has not been updated to the August09 dashboard. Although some consoles with the 7371 kernel have already been patched to stop the JTAG hack.
    2. Some soldering skills.
    3. A computer with a LPT(printer) port.

    What does the JTAG hack allow me to do?
    The JTAG hack unlocks your 360 and gives full control over it. Allowing.
    - Linux
    - Homebrew
    - Unsigned Code
    - Use a Re-booter(Freeboot or XBReboot)

    Where can I learn how to do the JTAG Hack?
    You can learn how to do the JTAG hack with the tutorial here.
    How to do the JTAG Hack/Dump NAND/Install Xell

    Where can I learn how to dump my NAND?
    You can also learn how to dump your 360's NAND image here.
    How to do the JTAG Hack/Dump NAND/Install Xell

    Can this be done to all motherboard revisions?
    Yes, all motherboard revisions are vulnerable to this hack. But the dashboard update on August 10, 2009 patched this hack. Some consoles that were manufactured or refurbished around June/July already have the patch applied. Which is why some consoles with the 7371 kernel are not vulnerable.

    How do I know what kernel version I have?
    In the dashboard go to System Settings>Console Settings then scroll down to System Info. Your kernel version is shown here. In this picture the 360 has the 8955 kernel applied. This console is not vulnerable.


    Kernel Vulnerability:

    8498 and Higher - Any console with a kernel 8498 and higher have been patched to stop the hack.

    7371 and lower - Any console with the 7371 kernel or a lower version of the kernel are most likely vulnerable to the hack.

    7371 - This is the "iffy" kernel. With this kernel you have to dump your NAND to make sure that you have a vulnerable CB. Some consoles with this kernel already have the patch applied to them and cannot be JTAG'd.

    How can I tell if my CB is vulnerable?
    First you have to dump the NAND image. Which can be learned how to do here.
    How to do the JTAG Hack/Dump NAND/Install Xell
    Second you would open it in Degraded 1.1 which can be downloaded from Xbins. This is the directory to get to it.
    Code:
    /XBOX 360/development/kernel/downgrading/
    Your CB version will be displayed.


    Exploitable CB versions:
    1888, 1902, 1903, 1920,1921: exploitable xenon
    4558: exploitable Zephyr
    5761, 5766, 5770: exploitable falcon
    6712, 6723: exploitable jasper

    Non-Exploitable CB Versions (CD = 8453 for all of them)
    Xenon: 1922, 1923, 1940
    Zephyr: 4571, 4572, 4578, 4579
    Falcon/Opus: 5771
    Jasper: 6750




    freeBOOT


    What is freeBOOT?
    Freeboot is a Xbox 360 re-booter. This will allow you to boot into the latest dashboard released by MS without the kernel on your 360 changing. Freeboot works on Xenon, Zephyr, Falcon, and Jasper consoles with 16mb flashes.

    What does freeBOOT require?
    Freeboot requires you to have a second NAND. This means you have to do one of the following:
    - XD Card Mod
    - Install a CygnosV2
    - Install a CygnosV1
    Freeboot also requires the JTAG hack.

    What can I do with freeBOOT?
    Freeboot allows you to:
    - Boot into the latest Xbox 360 Dashboard without changing your 360's onboard kernel.(Play the latest and greatest games)
    - Your 360 will accept any type of SATA harddrive(Use any SATA HDD)
    - Removed LIVE/PIRS signature checks(Free content for this console)
    - Removed XeX signature checks(Mod games)
    - Use Emulators
    - and more

    Does XeX Loader work with freeBOOT?
    Yes, XeX Loader was tested with freeBOOT and works perfect.

    Can I go on Xbox Live with this?
    If you were to go onto Xbox Live with this. It would not be very hard for MS to pick up on the fact that you are using a rebooter. You will most likely be banned quick.

    Where can I download freeBOOT?
    You can download freeboot on Xbins
    Directory is:
    Code:
    /XBOX 360/development/freeBOOT/


    How do I install freeboot?
    I was not able to locate a tutorial for this. But the readme does include instruction on how to install freeBOOT onto your 360.



    XBReboot

    What is XBReboot?
    XBReboot is another rebooter just like freeBOOT. It has mainly the same features that freeBOOT has. But is able to be flashed straight onto your onboard NAND instead of on a second NAND. Only downside is XBReboot is not as stable as freeBOOT.

    What does XBReboot require?
    Does not require a second NAND.
    Just like freeBOOT. XBReboot requires the JTAG hack.

    What can I do with XBReboot?
    You can do the same that you are able to do with freeBOOT. Wich includes:
    - Boot into the latest Xbox 360 Dashboard without changing your 360's onboard kernel.(Play the latest and greatest games)
    - Your 360 will accept any type of SATA harddrive(Use any SATA HDD)
    - Removed LIVE/PIRS signature checks(Free content for this console)
    - Removed XeX signature checks(Mod games)
    - Use Emulators
    - and more

    Does XeX Loader work with XBReboot?
    Yes, I personally have XBReboot installed on a JTAG'd 360 and XeX Loader works perfectly fine without hiccups.

    Can I go on Xbox Live with this?
    If you were to go onto Xbox Live with this. It would not be very hard for MS to pick up on the fact that you are using a rebooter. You will most likely be banned quick.

    What is the difference between XBReboot and freeBOOT?
    XBReboot does not require the second NAND. But is not as stable as freeBOOT is. freeBOOT had more developement time than XBReboot did.

    Besides stability issues are they the same?
    With stability issues aside. Both XBReboot and freeBOOT are basically the same thing. They both have their small differences but for the most part are the same.

    Where can I download XBReboot?
    You can download XBReboot from Xbins.
    The directory is:
    Code:
    /XBOX 360/development/XBReboot/


    Is there a tutorial on how to install XBReboot?
    Yes, in the readme file that you get when you download XBReboot there are instructions. But here is a tutorial on how to install.
    How to Install XBReboot


    Which Re-booter should I use?
    If you do not know how to do the xD Card mod or cannot find a tutorial on it and don't want to spend money on a Cygnos V2 or V1 chip then I suggest using XBReboot since it does not require the second NAND. If you have a second NAND then I suggest using freeBOOT since it is more stable than XBReboot and will run better.
