I am very happy with this TWRP. Everything is working so far on EMUI, Android 8.
Data wipe is possible, cause OEM Path is excluded.
Vendor.img and System.img and recovery_ramdisk can be flashed by choosing img to the related img.
Backup, restore of all shown Partitions working perfectly.
Decryption of storage if using Fingerprint /PIN is working. Full encryption support for data..
Many thanks to @Pretoriano80 for this awesome and first most complete TWRP for Mate 9 :good::good::)

BTW: @Blackball had tested this TWRP for P10 Plus and it is also working on this Device (so it will run also on P10).
Many thanks for testing too :good:

This is good to know... Going to have to give this TWRP a try. So what, to decrypt data, do I just have to format data in TWRP or?

Format data is only necessary if installing AOSP based Roms which require this (in installation guide)
But for Stock Firmware you don't need to decrypt (format) anything because encryption is fully supported

Of course, you can't install older Stock based Custom Rom which mount data in the updater-script without /dev/block/dm-0

If it's ask for password, then insert the same passwords/pin/pattern that you are using in Android, so TWRP can decrypt the internal storage.
That's the whole purpose of having a TWRP with decryption support.

Hi, I really appreciate this recovery, just have one question: is there a way to enter the decryption pwd only once and not with every TWRP start? Would make things easier (even I understand the current way is much safer...). Thanks and respect!

    No, it's designed to work like this!

    If your Phone is rooted, with Root Filemanager like FX Explorer or Mixplorer you can copy from /system/build.prop and /vendor/build.prop
    I just attached the build.pro files .Using RR remix treble project
