I went back and followed the procedures exactly as you've written them, except for using a later version of chameleon.

And I got in!

But not much was working, so I started with Multibeast and Using Kext helper I installed a Kext for intel Ethernet. But on restart I couldn't even get to the sign in screen. It said it failed to load Kext com.apple.driver.AppleRTC

So now I'm just starting over with the reinstall of the OS

In the future, when I try a Kext that breaks my hackintosh, is there a way to get back in there and undo the changes without having to reinstall everything? Thanks!
