Hey guys,this guide was made by Joossshhh-x and myself. Although, I fixed it up a little more to my liking because I thought the XboxMB community deserved a nice guide for Jtags. So, here you go. 
JTAGS
What a Jtag is
[details=Open Me]A jtag is an xbox 360 that runs unsigned codes. It allows you to access everything the xbox 360 has to offer , unlike a normal xbox which only gives you part.
If you run Xex menu . You can play xbox 360 games and emulators from it. You must have the games saved to your Hard drive device , which can be done by copying the dvd to your HDD or by extracting the .iso of a game and putting that on your HDD.
This also allows you to modify games that you have by changing the default.xex or default.mp.xex . For example , 10th lobbies for MW2 were made by modifying the game and loading them on a jtag via the default(.mp).xex.
You can also run custom made dashboards . Freestyle dash is one of them .These are a new dashboard layout for jtags . On a version of Freestyle dash I have you have the option to change the LED lights from Green - Orange - Red . . You can also change the fan speed and see the temperature of the CPU and the GPU .
A jtag is worth getting as in the long term they are a good investment if you buy games regually , for solo mode , as you dont have to purchase them . [/details]

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 Xenonâs which requires just 2x 1n4148 diodes. Iâve never used this method before so I canât 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.
Soldering the cable
Soldering is generally pretty straight forward. You actually donât need any solder for the motherboard end, as the holes all have solder in them. So you just need need to heat it up and slide the wire through. I suggest using at least a 30w iron as a 15w will have trouble getting the lead free solder hot enough. All resistors on the connector are optional, itâs just to prevent damage as some ports are 5v and the motherboard is 3.3v.
Here are some bigger pictures
Xenon
All others
Recently there has been a new way to wire Xenons that is supposed to be better, I have never tried it but I have included the diagram on how to wire it.
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 donât 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, donât worry. You only have a problem if canât 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.
Youâre 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 youâre 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 youâre 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 donât 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:
fuseset 05:
My CPU key would be aaaaaaaaaaaaaaaabbbbbbbbbbbbbbbb
It should 32 characters.
My avatar is not there
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 any 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 disc to update.
Thats how to make a Jtag . Still confused PM me. [/details]

How to put DLC on a Jtag
Open Me
Requirements:
A HEX editor:
YarisSwap:
DLC patcher:
The DLC you want: get it off a friend or look at these links i setup: Here (Just a txt doc with links in it)
DLC you downloaded on your own XBL account (can be free)
A Jtaged xbox
The latest TU for the game your DLC is for (found in cache folder on xbox HDD (if game has the update))
A normal xbox (to download DLC from your profile)
Retrieving our license key
First off you want to open DLCPatcher.exe and click open file and locate the DLC what you own.
Open Me
on the second line down you will see some numbers and letters (i hid half of mine). That is your license, its tied to your XBL account and the DLC needs that licence to work on your account so make a note of this as you will need it later.
Getting the DLC ready to put your key into
Now you need to Yaris Swap the DLC before you put your key into it, This may already be done if you downloaded it from the internet but to check load up the DLC in DLC patcher and it will look like this: [details=Open Me]
[/details]
Now we need to get our DLC to look like like that so if it already does you can move onto the next spoiler, if it doesnât keep reading.
Open up YarisSwap.exe and locate the DLC you want
Open Me
Then hit the âHex mod - Yaris Swapâ button (its hard to miss)
Open Me
Now you have Yaris swapped the file, if you open it in DLC Patcher you will see the FFFFâs
Open Me
Hexing in your own license
Open Me
Now we have to enter our own license what we found earlier into the DLC we want.
To do this we need to open our DLC in a hex editor
Now use Ctrl+F to start a search and key in:
ff ff ff ff ff ff ff ff
make sure type is selected as Hex!
Open Me
when you click find you should see something like this:
The parts of the HEX are color coded with the parts you saw in the DLC Patcher.
Open Me
what you now want to do is replace the RED and YELLOWFFFFFFFFâs with your license.
For example, if ,my license was a1 00 00 2e 9d 4e 00 e1 it would look like this:
Open Me
Then you will click save and it should save within a couple of seconds.
Open Me
If something like this appeared for a long period of time it means that you have added extra data not overwritten it so you should quit the HEX editor and load a fresh copy
Now, once you have successfully saved the file, if you open it up in DLC Patcher again you should see something like this where a100002e9d4e00e1 would be your license:
[details=Open Me]
