Yea that went unnoticed for me that there was mod1 version that was testing haswell gpu BiOS, I saw the original "mod" that Stasio posted. mod and mod2 are working as they are hd4000, can't you remove those "bad" links in your post?
Updated "bios" from F14 to F15q, them modded F15q like below, but with Phoenix tool 2.08 instead. Flashed and it finally works. Thanks.
Just choose other, select module if not by default use v2.08 or below..... no RW Everything report needed... Add slic... and done
