ok here is the deal. I have a pc without a lpt. so i searched the internet and found this usb spi nand flasher
http://www.360usbspi.com/index.php?main_page=product_info&products_id=1
i have installed nandpro and portio. i have tried the nandpro gui and jtag tool with no luck finding my xbox. it sees my programmer but wont detect my nand. if there is a way to test or program this chip with another hex that would be awsome. i have tried resoldering my wires and still nothing. the wires are about 5 inches and im using 30awg solid wire with a diode on pin 4. the flasher has resisters built in as you can see on the web site. if you have any info im at a dead end. Thanks in advance.
