EMUI:

Use THIS tool in combination with the EMUI files linked above. It'll guide you through the installation.

Magisk:

I would use the magisk canary release.

I prepared a patched ramdisk here for the lazy folks. Flash it after you're done with the rom installation.

Code:
fastboot flash recovery_ramdisk MagiskPatchedRecovery.img

Gpay:

Working for me when hiding google stuff in magisk and using THIS module.
