Dashboard downgrade problems

I have an RGH3 16mb Jasper and an RGH3 16mb Tonasket. I have had success with the 17559 kernel (Metro dashboard) and the 9199 kernel (NXE dashboard. Both Xboxs fail to boot the 6717 kernel (Blades dash) and the 13604 kernel (Kinect dash).

I hate the metro dash, so I would love to run the Kinect dash. It supports games that the NXE dash doesn't. I am using the Glitch2 RGH3 XeBuild options. Why does 13604 fail when 9199 doesn't? Anyone have any luck doing what I am trying to do?
