I want to JTag my xbox and started following a tutorial online. opened my xbox, soldered into the motherboard for dumping nand and started dumping nand using lpt cable that i made. I realized that lpt was taking forever to read nand as i've 256mb jasper and i must get an spi flasher. my pc was turned off while dumping nand due to load shedding and the number of blocks it read was more than 03FFF. now i tried turning my xbox 360 on and it shows red ring of death. secondary error method showed 0022 error which is gpu related. now i dont understand whether there is something wrong with hardware or has it something to do with nand. Please Help...
