Well I went ahead and ordered the usb spi programmer that I linked above. in the worst case I can add it to my collection of programmers. So far it consist of an ART programmer, blackcat USB, and multiple DIY PIC chip DEV boards. I contemplated on tryin a DIY solution but for the $10 or so it wasn't worth digging it all out.
I have been flashing xbox 360 since the beginning but Ive been out of the scene for awhile. This is my first Slim so im trying to catch up.
I believe this is the Corona V4 or V3 board. The pictures shown on the identify guide show it as a V4 but videos show it as a v3 so im still trying to figure that one out.
Is there a tutorial that I am missing somewhere? I would think that one would exist to dump the Key only without all the RGH/JTAG stuff.
From what I can tell you only need the usb spi programmer (Nand-X) to dump the FW from the NAND chip. Is this correct or am I missing something?
