Instructables
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.

Step 1: 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.

Step 2: 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.

PLEEEASE Re-upload the files ASAP!!

Anybody know if doing something along these lines would allow you to run custom maps?

I'm thinking custom zombie maps for world at war split screen like you can do for PC.

If it is possible that would be awesome always wanted to play a map I made with people that I can actually see and talk with.
Great tut thanks for putting it up.

I am selling my NAND-X Xecuter (used once) for best offer. Contact me if you're looking to JTag your Xbox.
I NNNEEEDD help cause when i putted black ops 2 in my jtag it broke it and i dont know what to do ...
Thanks for the tutorial, although jtag'ing is outdated now. Reset glitch hack can work on any console although it is more expensive to pull off. At jtag xbox 360 there pritty cheap but still...
does this work for 2.0.15574.0
my computer won't let me use port95 i have 64 bit but i don't know which compatibility to change it to
so um nvrmind figured out the compatibility doesn't work still though
hey how do i change its compatibility

Looks kind of shady to me. An entire domain devoted to only this supposed exploit. Not to mention is claims it requires a full xbox live connection. Why???
Lastly skibbadee just joined to apparently post that comment.
Remember folks, if it seems too good to be true, it probably is.
dude, ita jtagging, look up thetechgame and se7ensins, entire communities dedicated to doing this
"dude", my comment was a reply to skibbadee, which is the reason my comment is indented below his. :) His comment suggested a highly questionable method of soft-modding your xbox, and made all kinds crazy promises about what it could do.
have you personally tried this method
poolopa992 years ago
is this undetectable???
no, if you go online with it you will get banned within the first hour, its for offline use and system link only. its worth it if u host cod lobbies

bprince32 years ago
2 rrod = overheating
3 rrod = hardware issue (if you hold sync button and press eject button 4 times the lights will give you the 4 digit error code.. one digit every time you press eject.)

error codes
4 lights = 0
1 light = 1
2 lights =2
3 lights =3

No man sorry.
I have an XBOX 360 Slim with Liteon 16D4s DVD (F/W 9504) since October 2011 when it was purchased anew. I have never connected it to internet, so the dashboard hasn't been updated ever though I haven't checked what the current version is. Will I be able to JTAG it to be able to play copied games? I'm not interested in XBOX Live at all. Thanks!
sorry but you can't jtag any slim however you can flash the dvd drive or Reset glitch hack it.
wondering if u can help me out dont know if i have jtagable xbox my system info is as fallows d:2.0.7363.0 - k:2.0.7363.0 (bk:2.0.1888.0) x:4b5e-03a5-c6fc-d3ed its a non hdmi mnf date is 2006-03-02 thanks ahead of time
you should be able to just dont update the dash yet

This goes out to all having trouble dumping nand through lpt
1. make shure 360 is plugged in both wall and motherboard
2.make shure plugged up to lpt good and snug

no results then go into to system bios and check if lpt is
1. enabled
2. set to EPP+ECP mode or into normal if in EPP+ECP

still no results
1.check soldering
2.check soldering
3.check soldering

nothing again?
1.check direction of diodes
2.add/remove the 100 ohm resisters on pins 1,2,14,16,17

nothing again bad lpt port/xbox

Some things I've found which I hope will be useful:
While trying to read your nand, you get the flashconfig of 0x12000 and/or error: 0 reading block recheck all your points to the m/board. I spent a couple of hours trying to figure out what is wrong. In the end I removed and resoldered all my points again and it worked.

Reading your nand, a message of "error: 0 reading block xyz" doen't mean you have zero errors, it means it can't read the nand.  (Probable resolder time)

.....
Testing LPT device address:03BC
Could not detect a flash controller!

Means your soldering is bad or you haven't attached the power lead to your xbox (Don't switch your xbox on, just give it power.  This powers the eeprom so you can read and write to it). Word of Warning. It can't be in a RROD mode at this point as it still won't read even if your soldering is perfect.

Get several nand backups and compare them with a hex compare tool like wxHexEditor.  There should be no differences

As it takes an age to backup the nand, you might want to consider writing yourself a batch file to collect 4 copies of your nand or copy the 4 lines below and paste onto a dos window (they will run in turn)

nandpro lpt: -r16 nand2.bin > logfile.txt 2>&1
nandpro lpt: -r16 nand3.bin >> logfile.txt 2>&1
nandpro lpt: -r16 nand4.bin >> logfile.txt 2>&1
nandpro lpt: -r16 nand.bin >> logfile.txt 2>&1

You could set this off before you go to bed and when your up the next morning, you should have 4 nand.bin files waiting for you.

If your running Degraded to initially check the flash file and it keeps crashing on you, Open it up again and click "settings".  Set the following 2 settings
1BL key an enter DD88AD0C9ED669E7B56794FB68563EFA and tick the box.
File system start to 39.
If you've already done this, open a .bin file in a hex editor and look for the string near the top of the file:
2004 - 2007
Change it to:
2004 - 2005
and write back/save the file.  Downgraded should open the file now.... or use 360 flash tool at the top of this guide if you give up

If you don't like soldering, erm well tough really - neither do I, but you could buy a NandD-X (google it).  Currently £27 or $40US.  These are pins that are soldered onto your m/board, but you can't go too far wrong with them.  They connect back to a box of tricks which sends the data via usb back toy your PC.  This solution looks very neat, but if your tight like me and would like to reuse your item, you could look into getting just the "NAND-X Pin Header Cable" (google with quotes) £3 or $4.50, chop the ends off and attach to your LPT port cable *WITH RESISTORS AND DIODE" or buy some pin headers from ebay and make your own pin headers up ("8PIN GOLD DIP IC SOCKET PANEL ADAPTER SWAPPING").  Solder one to your m/board and cables to another.  They can act like plug and socket then, so you can flash again at a later date without resoldering again.  Note: Untested.  Just bought from ebay 30 mins ago (£1.30 for 10.)

Persevere.  It will take a while, but you will get there.  From 1 week ago when I had no idea about the 360 to now, running FreeStyle Dash and putting it back in its case for good.
