error validating the installer data [Mojave]

[abdalmoniem]

so I changed the SMBIOS of my existing build to MacBook Air using clover configurator and went to the app store, started and cancelled the download of macOS Mojave several times until I managed to get it to download the full 6.03GB installer. I then followed the guide in https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093 and used createinstallmedia command:

sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/install_macos --nointeraction

this one made the installer fail
I then used the command:

sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/install_macos --nointeraction --downloadassets

to download any missing assets required by the installer, it then downloaded ~250MB files and proceeded as usual. but it also made the installer fail with the following error:

An error occurred validating the installer data. The download is either damaged or incomplete.
Redownload the installer and try again.

Validation Error Mojave

error happened oct 1st 2018 on my HP Pavilion G6 1066se

note: this error happened when I used both commands mentioned above.

I also tried to format my drive as APFS and JHFS+ which seemed to have no effect whatsoever. I really don't know what is the problem here and could use some help!

my build is:

• hp pavilion g6 1066se
• intel core i5 2450m
• intel hd 3000 + amd radeon hd 6470m 1366x1768
• 8gb of ram

I attached my clover configuration since I couldn't boot to the OS to use the automatic PR tool.

MacBookPro14,1 is a bit of a stretch on Sandy Bridge hardware.
Maybe SMBIOS of Ivy Bridge would make more sense.

I re-downloaded the full installer again from another mac and with MacBookPro14,1 SMBIOS and it now works fine but with no QE/CI acceleration, I copied the AppleIntelHD3000* kexts from High Sierra but it kernel panics, so I reverted back to High Sierra until I find a solution to the problem

I would not bother with old kexts. Just plan on sticking with 10.13 as you would on a real HD3000 Mac.
