you wire the coolrunner for rgh2, you install the nand rw cables, you dump the nand 2X, and then create and write xell. you will also need to program the coolrunner with the right timing file, any one for a falcon, as the boards are basically the same, the opus doent have hdmi, while the falcon does. then hit the eject button, wait for it to boot. RGH2 can take a while on falcon/opus consoles. get the cpu key, create xebuild image, write xebuild image, turn on xbox normally. that pretty much covers it in a nut shell.
