Okay, I'm now I'm pretty late on this. Most links I found doesn't work anymore.
I'm trying to get root on my Mate 9 MHA-L29. The bootloader is already unlocked and I'm on OpenKirin's Resurrection Remix rom.
I used TWRP 3.2.1-0_OREO.img, then flashed the last version of SuperSU you linked here:
But when I reboot, the SuperSU App still say "Root undetected".
Also in your first post you reference https://forum.xda-developers.com/mate-9/how-to/guide-how-to-root-mate-9-decrypt-data-t3569986 with is now closed and all links are dead. So I don't know how to obtain those Public_data.zip and Full_HW_data.zip

And the flash worked without errors.woops, I haven't updated OP since my Mega account got banned.
But you can use this: https://mega.nz/#!ZTBQXZra!JHUocH9oMEApULxfLYm9VO5UPhjHNMGLymkXDY_ihhI
It's 2.82 SR5.
And this TWRP: https://mega.nz/#!9aoASShT!KJkpC_Ll8HZowWF1_fU0olWiHHaeSZuYE3xc3au8EIg
That supersu doesn't remove encryption.
If you want to decrypt, let me know and I'll upload.
