How to install the jtag hack on an Xbox 360
What you need:
T10 screw driver
T8 screw driver
USB nand flasher or LPT cable
360 flash dump tool
Tool for building the Rebooter (easy freeboot is my personal prefrence)
Make sure that your console is on dashboard 7371 or lower and manufactured before 20th June 2009
First off your gonna want to dismantle your 360 - I'm not going to put a guide here, they're all over the internet.
Next, you will need to solder either your LPT cable/usb flasher to the board. If you're inexperienced at soldering, watch this video first or get someone with experience to do the soldering for you.
The points are show below.
Resistors are optional, but it is always adviced to put a diode between J1D2-4 and lpt-11.
You just need to solder the usb flasher's points/headers to the board and plug the usb into your pc.
Then install the drivers.
Instructions to install drivers:
Press start, search program or file, type: hdwwiz, press enter
Uncompress the nandpro Rar
I personaly prefer writing out a bat file for using nand pro
Create a txt in your nand pro directory.
The contents should look liked this if you are using usb and have a 16mb motherboard. If you were using LPT you would replace the USB: with LPT:
and if you had a Big block Jasper you would replace the -r16 with -r256 for a 256mb jasper or -r512 for a 512mb jasper and a dev kit it would be -r64
nandpro.exe usb: -r16 backup1.bin
nandpro.exe usb: -r16 backup2.bin
nandpro.exe usb: -r16 backup3.bin
save the txt as run.bat
Checking the files with 360 Flash Dump Tool:
If an image has bad blocks a 3rd tab will show up in 360 flash dump tool detailing where the bad block is, if the badblock is in the same place on all your images dont worry. but if not make sure you have atleast 2 images that match
Bad block image
if you have atleast 2 matching images you can continue and write xell or xellous to your xbox 360's nand
Personaly i use xellous as it saves work later on. download the xell/xellous images from xbins and place them in the nandpro directory
To write to the nand, you need to edit the bat you made earlier
Change the "R" to "W" and the backup#.bin to the nane of the xell or xellous image
nandpro.exe usb: -w16 xellous.bin
if you boot the 360 now it should give u a E79 error.
as we need to add in the the jtag wiring
Diodes are always optional:
Zephyr, Opus, falcon, Jasper:
3 different methods here
Method 1 traditional and easiest to solder but can lead to E79 on bootup
Method 2 The one i used for a long time worked well and is clean.
method 3 we can use a aud clamp method
Not best picture, but only one i can find
there are others but theses are the ones ive tryed and know work
once you have finished soldering the points the xbox should boot xell/xellous to revel your cpu key
or if you have a network cable connected you can get you cpu key by entering the ip address of the console into your web browser
you need combine line 4 and 6 to reveal your cpu key
Note down your cpu key - it will be required
Building rebooter image:
my personaly choose for building rebooter images is using easy freeboot but you can use pigmaker or jtag tool or the ihc one cant remember what its called
first you want to download and unrar the program
then start the program
depending on what wiring method you may need to change the SMC config under fixes on Easy freeboot. or if you are not going to have a dvd drive in your 360 select the no drive fix.
Method 1, 2 use "Stock"
Method 3 use "Aud_clamp"
and if you use "Tray_open" and "aud_clamp" Fix then select "Aud_calmp and Tray_open"
next press create freeboot image and select the image you dumped earlier from your 360.
confirm your motherboard.
either enter the cpu key you wrote down earlier and press ok or click get cpu key and put in the ip address of you jtaged xbox 360 console then press ok
a console window should come up and if all goes well it should ask you to press enter to exit
a save dialog should apear save this somewhere where you can find it again
writing the image to the 360:
Reatach the dvd drive if you have not selected to use the no drive fix on easy freeboot
if you originally flashed xellous to your 360 then just put the image onto a usb stick and call it updflash.bin
Next, plug the usb into the 360 then remove the power brick for 20 seconds, then plug back in and then press eject - the image should start writing.
Or, you can stick the updflash.bin image into the nandpro directory and edit the file name at the end of the bat comand you created so it looks a bit like the command below.
nandpro.exe usb: -w16 updflash.bin
run that wait for it to finish.
once its done power cycle and then see if the xbox boots to dashboard.
if console e79s check wireing and if thats ok try rebuilding the image
if console boots to dashboard you can put the 360 back together now
There you go you - should now have a jtaged xbox on the latest rebooter kernal.
