Are you sure you have completely followed the guide on p1? No offense, but for me it worked out. My steps:
- just for dual boot: (installed Win10, expanded EFI partion to 200 MB)
- repartition USB drive 1 partition, MOS journaled, GUID partition scheme
- created Mojave installer with createinstallmedia...
- installed Clover (switched to EFI) to USB stick
- used Clover Configurator for mounting EFI partion of USB stick
- deleted all content of Clover folder on EFI partion
- copied all files from OP clover zip to the Clover folder
- edited config.plist in Clover folder with Clover Configurator --> setup ID, Serial, Bord Serial, saved
- booted from stick, installed OSX (1 reboot has to be catched with USB stick)
- booted OSX with the help of the USB stick
- installed Clover to hard drive
- mounted hard drive EFI partition with Clover Configurator
- replaced all content in EFI partion Clover folder with the one from the EFI partion USB stick
- just for dual boot: (booted Win10, used BootIceX64 for setting Clover as first boot entry)
From then on OSX was booting up fine, everything works (wifi card still has to be replaced though)
