How to JTAG your Xbox 360 and run homebrew



I will be going over how to install XBR and Xell onto your Xbox 360. Installing XBR allows you to do many things such run unsigned code(homebrew), install any sized hard drive(even 3.5in desktop hdds!), ftp into your box, and custom dashboards. There are endless possibilities with being able to run any code you want. You are able to modify Xbox 360 games to run custom maps and cheats. You can also launch games off the hard drive without a disc. It should cost you around $5 in parts, maybe even free if you have the parts already.


Finding out if your Xbox is exploitable


Your kernel must be kernel 2.0.7371.0 or lower for this to work. You can do this by opening up the system info tab. After there is one more step to check if it still is exploitable, but you have to build your cable to dump your nand first.





Getting your parts


Tools
Soldering iron
Solder
Computer with LPT port.

Parts
1x 25 pin d-sub connector (male or female depending on which kind of cable you have)
Digikey # 225FE-ND

1x 25 pin d-sub cable (lpt cable) You can actually skip the cable if you buy a male connector and make your wires long enough to extend from your xbox to the computer
Digikey # AE9863-ND

3x 330 ohm resistors (only for Xenon motherboards)
Digikey # P330BBCT-ND

1x 1n4148 switching diode (if you have Zephyr, Falcon, Opus or a Jasper get 3x of these)

Refer to the image below to tell what kind of 360 you have.

There has been a new update to the standard wiring you should use for the JTAG wiring on Xenon's which requires just 2x 1n4148 diodes. I've never used this method before so I can't really help as much if you have problems. But I would suggest going with it instead since it is supposed to be electrically superior and uses less parts so less room for failure I guess.





Dumping the nand


Download the files here (I forgot to include nandpro get that here )
Extract the rar, and open up the nandpro folder
install port95nt.exe (if running vista or 7 set it for compatibility mode for xp.)
Plug your Xbox 360 in, but don't power it on.
Plug the lpt cable in
Pop open cmd and change directories to your nandpro folder
type nandpro lpt: -r16 nand.bin
It will start to dump, this will take 35 minutes
Type nandpro lpt: -r16 nand2.bin and dump it a second time.

If during the dump it has trouble reading blocks, don't worry. You only have a problem if can't read block after block, which means something went wrong in the middle of the dump and you have to restart it again.

If you are having issues having nandpro detecting it, go over and double check all of your soldering. If you skipped out on the diode, try adding one, and just restarting your computer has fixed the issue quite a few times for me. You also want to make sure your cable is short as possible.


[/code][code]


Testing if it's exploitable


You're going to want to open up degraded included in the file pack. Go to settings and under 1BL key make sure it says DD88AD0C9ED669E7B56794FB68563EFA and is checked. You are also going to want to change file system start to 39.

Open up your nand dump and look at the CB version

If your CB is the following you're in luck!

Xenon: 888, 1902, 1903, 1920,1921, 8192
Zephyr: 4558, 4580
Falcon: 5761, 5766, 5770
Jasper: 6712, 6723
Jasper Arcade (256/512): 6723 or lower is Exploitable

If you are unsure if yours is exploitable, you can also check if CD = 8453, if it does you're out of luck.





Extracting the keyvault, injecting and flashing XBR


Select the proper XBR for your motherboard included in the rar file and put it in your nandpro folder. Rename it to xbr.bin to make things easier.

Open up cmd, navigate to your nandpro folder and type

nandpro nand.bin: -r16 kv.bin 1 1
nandpro nand.bin: -r16 config.bin 3de 2

Then typenandpro xbr.bin: -w16 kv.bin 1 1
nandpro xbr.bin: -w16 config.bin 3de 2

Now for the flashing!

Just type and wait 35 minutes
nandpro lpt: -w16 xbr.bin


Getting your CPU key


Reassemble your 360, and boot your 360 with the DVD drive ejected. Or if you don't have a DVD drive you can plug in a wired controller into the back usb port.

You should see a blue screen pop up and whole bunch of things fly by. When it says CPU fuses, your either going to want to write really fast or snap a picture.

fuseset 3 and 5 or 4 and 6 is your cpu key.

So if it said
fuseset 03: xxxxxxxxxxxxxxxx


fuseset 05: yyyyyyyyyyyyyyyy

My CPU key would be xxxxxxxxxxxxxxxxyyyyyyyyyyyyyyyy

It should 32 characters.


Installing a 3.5 in desktop HDD


This requires you to cut the end off a sata cable and solder it under the HDD connector.

Wiring goes as follows
Pin 1: SATA Signal GND
Pin 2: SATA Signal A+
Pin 3: SATA Signal A-
Pin 4: SATA Signal GND
Pin 5: SATA Signal B+
Pin 6: SATA Signal B-
Pin 7: SATA Signal GND

The side of the sate cable with the writing goes up, and you start left from right. You only have to solder the white shielded cables inside as these are the data cables. Just wire the rest of the ground wires some where else.

Where to get my 12v?
There are many spots on the Xbox motherboard where you can get 12v of power from, I picked the power connector on the bottom of the board as I'm not soldering onto any other connectors or anything.

How to wire up the sata power connector
Yellow: 12v
Red: 5v
Black: GND

Hard drives have been tested up to 2tb and worked successfully





My avatar is only a silhouette!


Usually your avatar will be a blank silhouette and it will tell you, you need to install an update to use them. All you need to do is download this update file, and place it on a USB flash drive, and plug it into the back usb port of your xbox. Your 360 should detect it and install it. Make sure you extract it first and the root of the drive is the $SystemUpdate folder. You can also burn it to a CD to update.

If you're paranoid you will brick your console because microsoft is out to get you and ruin your homebrew, you can look at the picture about removing the r6t3 resistor to keep from having your fuses blown.





As most of you all know jtags are patched online but this is just to help offline.
