Ya its after i install the kexts and the new config when it goes to boot its a black screen(normal) but i dont see any apple logo or anything with a flash light so i leave it and around the 3 min mark i get the verbose boot information but no KP and it just stays there. If i boot with the first config i can get it to boot with everything working. So im just going through it hopefully this week to see the item causing the issue.
The only reason you wouldn't be able to boot with the new Config.plist is if you didn't unlock your BIOS and change the DVMT settings and/or you didn't actually update WhateverGreen and Lilu.
The old config.plist has the the DVMT patch to let the laptop boot without changing the DVMT setting on the laptop itself. This patch does not work correctly with the new WhateverGreen and will result in inconsistent boots that will just get stuck at the loading screen with no KP.
The new config.plist does not have the DVMT patch and because of this your laptop will not boot unless you have changed the DVMT setting in the BIOS so it works natively with OSX.
The new config.plist also has new Framebuffer patch requirements to fix the black screen issue.
