Clean install High Sierra on Z270 not working (showing stop sign)

I am trying to clean install High Sierra in a already hackintoshed computer (with Sierra running fine in other drive) but nothing is working. The farthest I've reached is a stop sign when it is loading the installer. This is my setup:

  • Z270 SLI from Gigabyte
  • i7 7700k
  • GTX 1080
  • 16gb of RAM
  • EVO 850

This is the stop sign: https://support.apple.com/library/content/dam/edam/applecare/images/en_US/osx/mac-prohibit-symbol-screen-icon.png

I tried to use -verbose or -safe mode, but nothing shows up before this symbol..

I have tried most tutorials from this sub and tonyx86, but almost nothing worked or helped me so far. The biggest help came from this: http://hackintosher.com/builds/ga-z270m-d3h/ . I've been using his EFI package on Sierra for months without any problem. I tried updating the SMSBIOS to 18.3, since I have the same processor, and updating each kext file. It still works on Sierra, but I can't manage to start the High Sierra installer, since it shows the evil stop sign when +- 70% of the progress bar has loaded. I've read somewhere that I should be using a USB 2.0 on my computer to install, otherwise it will do kernel panic, but I'm not so sure since I've used a usb 3.0 to install Sierra and worked.

My current EFI package is this: https://www.dropbox.com/s/ow1igfqd4t4nw0v/EFI.zip?dl=0

Could someone help me? Thanks!!
