Sure.
When you extract xeboot you are a main folder with many folders inside of it. There you will have a 14699 folder where you should dump the file system files, not the extracted microsoft udpate. I was dumping the microsoft 14600 update in there, which was the wrong thing to do. After placing in the correct files I was able to build my xebuild image and am now on 14699

.
I didnt have a problem whatsoever. I used the stock (untouched) nand dump i originally dumped of 13604 to create the ggbuild image for 13604. So basically used the stock 13604 nand dump and used it with xebuild to create my xebuild image for 14699. It would probably be best to use your original nand dump rather than an old ggbuild image.
Many thanks to afiser!
