I went ahead and just created a new usb installer and used the latest efi I posted and it booted up fine, selected the install option and it loaded up recovery for installing. It zipped right past where yours stopped. Maybe hardware difference is the problem here considering it couldn't get past the light sensor.
I think you have the right idea starting with removing CPUFriend.
One thing i noticed is whatevergreen is way down in the list, I moved it up to Item 3. This is fine post install but maybe an issue for the installer.
I disabled a bunch of kexts that shouldn't necessarily be needed for install.
You don't need to delete the kexts, just try out this new config and report back.
@saschabo give this a try too, but I believe your issues are a bit different.
I'm curious what WiFi cards you guys are using as maybe that is an issue as well.
