I know a JTAG is for testing circuit boards and such and so I'm assuming that when one JTAG's a vulnerable xbox there using the vulnerable JTAG test port to read the nand and write to it but I'd like to know why certain spots need to be soldered on and how was it ever figured out that these spots were needed to perform this hack. I guess one could get the motherboard schematics and devise a way from that but are those available for each motherboard version?
I guess what I'm most interested in is why do you need to add theses wires (http://www.digitalre...09/12/Fdjmi.png) or (http://www.digitalre.../12/diagram.jpg). What are there purpose?
If there's a site that describes why the JTAG hack works then I'd be glad to take the link and give it a read. I'm just interested in this all and since I'm not highly educated in electronic circuitry I'd like to learn more.
Btw im not a complete noob asking for info I'll never understand. I do networking and computer repair for a living
