I used slushies guide the first few times. No problems at all. Have you actually attempted to flash? Also, make sure you have a 1 meg bios (if you're on a v 1.0 xbox). If you've not attempted to flash yet.... Do the first raincoat commad on slushies tut. This will back up your bios, and should provide you with an idea as to wheater or not it recognizes your chip. If you have tried to flash and got an error, post the exact error.
