It does work but first you need to downgrade your phone to nougat (Android 7.x) first and then it will work.

EDIT seller says its 4.4.23+ EMUI/Android Version: 8.0 is that the unlockable one or is there more to the version that says it?
You need the build number and security patch date.

Pretty much all EMUI 8 builds on the Mate 9 run a 4.4.23+ kernel, even up through the latest security patches.

Once you know the build number, find it in Firmware Finder, and find the build for that region that enables GPU Turbo. If it's an older build, then it's likely that you could use the official rollback firmware to get the bootloader unlocked.

Yup, .375 is the latest one that's good, after that .377 had GPU Turbo and issues with downgrading.

so im good to downgrade? i will message you when i get the phone in a few days thanks
You won't get into the trouble that others did with .377 or later, yes.

But there's no guarantee everything works nicely.

Do read as much as possible before doing anything.

Also keep in mind that Android 9 is coming soon so maybe you don't need to unlock and whatnot.
