Hi, I try to build my first hackintosh using Z370N WIFI with BCM94352Z card, i7 8700k and GTX 1060 6GB.
I have 20inch iMac early 2008 running El Capitan 10.11.6 which is not support by High Sierra.
So, I asked my friend to download High Sierra 10.13.6 on his Macbook Air for me and transfer to my USB drive.
I did the rest on my iMac, building bootable usb using latest UniBeast.
Did all necessary changes in my BIOS (F3 version) and boot using clover but stuck at HID:Legacy shim 2.
Since my mobo doesn't has USB 2.0, I use USB 2.0 adapter and manage to go trough and choose my samsung 970 evo drive to install High Sierra.
My PC restart and I boot again using clover and choose to boot from my samsung 970 evo to complete installation process.
After the apple logo finish loading and installation process begin, it stop saying : An error occurred while updating firmware.

Any advice to get trough this one?
