I had gotten my xbox 360 flashed to 1.6 Ixtreme firmware by a buddy of mine. Now that Wave 4 has came out, I need to get it updated to "1.6 firmware" I would have my buddy do it for me but me and him are no long in contact, so I am on my own. I don't know the first thing about this. So I was hoping one of you guys could give me a step by step procedure on how to get this upgraded. Please Also, when updated, will I need to open the xbox 360 again?
You'll need to determine which drive you have (http://microsoft.blognewschannel.com/wp-content/uploads/2007/02/xbox-360-dvd-drive.jpg) then take a look at the tut's in the ultimate sticky at the top of the first page.
