Thanks so much, guys. One thing I did notice, none of the guides you all posted show using the nand-usb device. Should I forget about buying that? Especially since I won't know what I'm doing with it?
You will find that using a USB nand flashing device better than fettling around with a homemade LPT cable.
I used LPT for my first few forays into nand reading/writing & although it works fine its time consuming.
Its 45mins or so to read a 16mb nand once, but you need 2 good matching nand dumps & then writing back is another 45mins or so. If you throw a few read errors into that equation you can easily lose the best part of a day.
With a USB device on the other hand reading/writing takes only a few minutes on a 16mb nand.
Once your console is JTAG'ed you can read/write your nand from a USB flash drive with flash360 but its always handy to have a safe backup of your original/hacked nand files you can write back with the usb flasher should you mess up.
