First, the symptoms were that internal screen fades to black after apple loading bar
Press brightness up key.
without any external devices attached, also when trying to connect external display with DisplayPort cable, it causes instant reboot.
Read post #1, "Problem Reporting".
I had to patch HD4000 kext though to increase framebuffer size to 16MB, as OS X HD4000 driver has a bug with high resolution monitors, so it solved graphics corruption on external display.
Perhaps this is causing your problem.
I would have to see the exact patch you're using (hopefully, you're doing it from config.plist).
and installed random kext that has no effect on anything with Kext Utility 2.66.
"Random kext"???
Kext Utility?
Both not recommended by post #1!!!
So the problem was that after completing all the post install steps, there's still something that is required to fix cache, permissions or something, but I have no idea what. You can see copy/paste from my post install steps attached on post #4773, I don't think that I missed anything in it.
As per guide, you should boot without caches, then rebuild cache. Read post #1, "Known Problems", "Audio".
