Steps (read through at least 1 time to know and be prepared):

Installing TWRP
1. adb reboot bootloader
2. fastboot flash recovery_ramdisk [ Filepath\TWRP.img ].
>  I put the TWRP .img file in C:\adb folder, so I simply type
>  fastboot flash recovery_ramdisk TWRP.img (for my case, that is twrp_bla_alp_0.7.img)
3. fastboot reboot (to restart phone)

N.B. As soon as you execute the restart command, UNPLUG the USB cable and keep pressing Volume UP, so the device will boot to TWRP. This is to avoid the device booting to OS, overwriting TWRP recovery.

Installing Magisk (using adb)
If you did not issue 'fastboot reboot' command in step 3 above, you do this
1. adb reboot recovery
2. adb sideload [ Filepath\Magisk.zip ]
>  for me, that will be 'adb sideload Magisk-v16.0.zip'

But I usually do 'Installing TWRP' procedure up to reboot, and do my Magisk flashing using phone menu, not adb method. You are free to try and choose your own way, too.

When you are done, welcome to a rooted and working Huawei Mate 10 phone!

Thank you and till then!
