Please help

Failed multiple times trying to update to Mojave from High Sierra. Used EFIs found on the internet, tweaked config.plist, etc. but no success so far. It always ends in a panic crash. What changes does an EFI require while changing from one version of macOS to other? Why won't an EFI which is working completely fine on one version doesn't work for the other? Let me know what I have to know regarding this.

Thanks
