hi grtdemo,
Thanks for this guide, followed this over the weekend on my El Capitan H170N build. I have been holding off to upgrade but thanks to your guide, I did it. Everything that I care about works
A couple things that differ from your guide
- The USB flash drive has to be USB 2.0
- USB 3.0 works using this guide :

- The audio works using Voodoo kext (version 2.9.1) :
https://sourceforge.net/projects/voodoohda/
- install only the 100/200/300 Series Audio Support using MultiBeast, then install the Voodoo kext
- Sleep works using WhateverGreen kext (version 1.2.0) :

- also need lilu kext (version 1.2.5) :
https://github.com/acidanthera/Lilu/releases
- use boot arg "ngfxpatch=pikera"
My hardware :
