Xbox 360:JTAG/Xenon Method

This is the only JTAG/R-JTOP wiring for Xenon motherboards. Do not use it if you have a non-Xenon motherboard.

Equipment Needed

Motherboard Soldering

  • Cut two strands of wire approximately 6 inches long.
  • Solder one wire on the end furthest away from the black line on one of the diodes.
  • Using the diagram below for reference, hold the unsoldered end of the diode against one of the J1F1 points on the board, and cut the wire to the length needed to comfortably reach one of the J2D2 points.
  • Repeat for the other diode and solder them in place, making sure that you solder the diodes directly to the J1F1 points.
  • Next, solder a short wire from point 4 to 7 on the J2D2 header. All points should be solidly connected so that a tug on the wire won't disconnect the wire.

Testing your Console

Once you've finished soldering, clean up any flux with isopropyl alcohol and cotton swabs. Partially re-assemble your Xbox 360, ensuring that:

  • Heatsinks are attached (if you removed them for some reason)
  • Fans are in place and plugged in (You can angle the fans on top of the heatsinks to cool them for testing)
  • The Ring of Light board is plugged into the front of your console
  • Your A/V cable is plugged into the Xbox 360 and into a TV or monitor
  • Your power brick is plugged in to both the wall and Xbox 360
  • (Optional) An ethernet cable is plugged into the Xbox 360 and your LAN (e.g. a switch, router, or directly to a PC)

Turn on your console, and it should boot into XeLL within a minute. If you don't have an ethernet cable connected, write down (and/or take a picture of) the "CPU Key" listed on screen. You can now go back to the JTAG or R-JTOP hack page and continue from the beginning of the "Decrypting The NAND" section.

  • If your console doesn't boot into XeLL, check all previous steps and double check your wiring accuracy and quality.

Troubleshooting

  • What should I do if I ripped off a soldering pad?
    • Look online for an alternate point to solder onto. Practice more on junk electronics before attempting to continue.
