This is my custom TWRP for the Honor9 (STF) phone. Finally after more than 2 weeks I've successfully added encryption support. I plan to keep it updated.

Capacitive button fix
Some people have the problem of missing capacitive buttons. The reason for this problem is not flashing a recovery but probably because something during firmware upgrade went wrong.
I made a custom kernel which should fix the capacitive button problem. This kernel also allows disable of SELinux with setenforce command.

ONLY for OREO

New: Proto8 kernel includes my capacitive fix. Download it here: https://forum.xda-developers.com/honor-9/development/kernel-proto8-kernel-t3780551

Old method with kernel compiled by me (not recommended, use Proto8 kernel instead):
  1. Download kernel
  2. Flash with fastboot.exe flash kernel KERNEL_BXXX_TOUCH_FIX.img
  3. Reboot into android and check capacitive buttons (enable them in settings if necessary)
  4. Flash stock kernel again if you want

Well tried to do a backup of my system and noticed that it failed to mount /system.
Logs are attached

Edit:
It can't mount rw, read only works as expected.

Yes I am B360 to be exactly, and I can confirm that rooting with Magisk works perfectly, buttons and flash keep working and safety net is not triggered.

Via custom recovery:
Download the latest Magisk zip file
Reboot to a custom recovery and flash the flashable zip
Reboot to system, and check whether Magisk Manager is installed and the version matches the latest one in the OP
If for some reason Magisk Manager isn't installed/upgraded automatically, please install/upgrade it manually!

This method and Magisk v16.0 right?

Does TWRP need system rw for backup? Anyway, Huawei added write protection in memory controller. So in order to mount system rw, a custom kernel is required. If you need it I can compile a custom kernel. Note that recovery and system have the same kernel now in Oreo.

To be honest I am not sure, you can back up without a problem (system) but I needed a few tries to restore but it worked. But I can't back up data.

Ok, i've flashed this TWRP, buttons and flashlight still working. Flashed Magisk v16.0. Root works, but SafetyNet is triggered. :confused:

------- EDIT -------

After reboot, SafetyNet now is not triggered! :laugh:

If i remove Magisk and flash SuperSU NetSafety will be triggered? In a future a flash of stock rom and a total remove of root will turn off SafetyNet or it will be triggered forever?

A working version of SuperSU with this TWRP and Oreo B360?
