How to JTAG your Xbox 360 and run homebrew

Featured

Step 3: Soldering the cable

Soldering is generally pretty straight forward.  You actually don't 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, it's just to prevent damage as some ports are 5v and the motherboard is 3.3v.

Here are some bigger pictures

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.

Don't use this outdated method if you have a Zephyr, Falcon, Opus or a Jasper. I used this and had to re-do it all a few days later because I got red rings, which is common with this method. Here is the best method:

You need, in total,
5x 100 ohm resistors (for LPT)
2x 10 000 ohm resistors
2x 2n3904 transistors
a db-25 male connector (for LPT)
1x 1n4148 diode (for LPT)

is it just me, or is EVERY picture I have found of the JTAG pin out BACKWARDS from the pins in reality...

acording from my link below and my LPT port, when looking from the FRONT pin 1 is on the top right...

ever JTAG picture i've seen, including the one above, pin 1 is on the top right when looking from the BACK... why is this? I'm wondering if that's why it is failing for me...
