I used myhack with generic extra folder. Need to install voodoops2 kext to USB installation in order for trackpad to work. Post installation, I used multifail to install other kexts. 
Need to install to S/L/E: voodoops2controller, b5722d(network), voodoobattery, voodoohda, aicpupowermanagement, applesmartbatterymanager, caldigitfastio, caldigitusbxhcl, sleepenabler kexts. 
Need to delete from S/L/e: applehpet (for USB to work properly), appleps2controller, appleacpips2nub, nullcpupowermanagement kexts. 
for intelhd4000 to work, need to use efi injection string ig-platform-id: 01660004  . Use chemeleon bootloader, chimera (chameleon, stolen and rebranded) caused kp. 
For "still waiting for root device problem", use the fix for ioahcifamily.kext from vahan's blog. 
Org.chameleon.boot: usekernelcache=no, graphicsenabler=no 
Touchpad 2 finger scrolling does not work. 
sleep works..i think.
