This tutorial shows you how to JTAG your xbox 360. The full version is available at http://www.tiaowiki.com/w/How_to_JTAG_XBOX_360_Using_TIAO_USB_SPI_Interface as I can only post up to 15 images, the full tutorial contains more detailed images! Tools needed In order to finish this task, you need to prepare the following tools/components: A ‘hackable’ XBOX 360 XBOX 360 USB SPI & JTAG bundle Solder iron, solder and solder paste. Software needed: Microchip USB package (contains PDFUSSB.exe for flashing PICFLASH.hex over USB) PICFLASH_v3b_plus2 NANDPro ( currently Version 2.0 d) Infectus NAND Checker (current Version 1.1) MD5 Comparison Tool (hex editors can do this) 360 Flash Tool ( currently Version 0.91) CD Info (currently Version 1b) The benefit of using this USB SPI inteface is, it does not require any parallel port (most PCs don't have it nowdays), it only requires USB port. Another advantage is speed. It is 10 times faster than the parallel port tool. OK, let’s start! How do I know my XBOX 360 is hackable? This is relatively easy, check the power connector: XBOX 360 power connectors Differences between Xenon/Zephyr: Zephyr has HDMI, Xenon does not. Difference between Falcon/Opus: Falcon has HDMI, Opus does not. If you have a Jasper box, you should also check which NAND size it has. Unplug all storage devices (HDD, Memory Unit etc.) and navigate to "System Settings", "Memory". If you don't see a storage device listed there you have a Jasper without an integrated Memory Unit, so you have a 16MB NAND. If a storage device is listed (with a symbol of an Xbox console in front) press the Y-Button and a summary from the storage device will appear. Jasper memory Identification: Capacity: 214MB = 256MB NAND Capacity: 451MB = 512MB Which Dashboard-Version does my console have? At first you have to find out which dashboard version your Xbox console has. Go to "System Settings", "Console Settings" and choose "System Info". The dashboard should show something like "2.0.7371.0". check the dashboard version It is possible to use the hack up to Version 7371, but starting with Dashboard-Version 8xxx it isn't possible anymore. With Jasper, beginning MFR July 2009, you have to read out the NAND first anyway to know for sure that the Hack will work. (The NAND should be read out anyway, doesn't matter which Mainboard-Revision you have).
