as far as i can see the tut is correct and from that i guess you don't have an orig nand backup to get your smc config and rest of files from
yes you just replace the patches that are in bin folder
create a copy of your xbr image so you have one safe and open it up in 360 flash dump tool v0.94 with your cpu key click tools and edit config and put your right mac to the console in and set your correct region if needed but mac you will want to change to the correct mac of console and save it and extract with ibuild
its best to have this from orig nand as it do help stop the rrod iv found out (only the case with freeboot makes no difference to xbr images so far lol)
hope this is of some help to you

Hey, just wanted to say thanks for the info and it worked out perfectly. I also extracted my SMC from my XBR image and then flashed using Xellous. Works great! Thanks to all who worked on this
P.S. I can play Xbox 1 games fine, not sure what the kxampatch is or what it really accomplishes.. If anyone would shed some light on this I'm sure everyone would appreciate it
A little more info... Used donor files (upgraded from XBR3) on a Jasper512. Hacked compatability files installed. Games load and returning to FSD from them works as well.
