Thanks to @topjohnwu, magisk canary builds officially support emui 9, albeit with some caveats.

Note:
This root requires replacing stock recovery with patched magisk init, which will then boot system with magisk support. This means that currently, TWRP or stock recovery and magisk can't exist simultaneously. Also, in order to boot with root, you will NEED to hold down VOLUME UP as the phone is rebooting or booting until the "device is booting" text is displayed. This tells the phone to boot into recovery, which is taken over by magisk init and booted into system with root. Failure to do this will result in the phone booting WITHOUT root or magisk.

I've gone ahead and patched the recovery_ramdisk for EVR-AL00 and EVR-L29.

What is needed:
ADB/fastboot
A computer
A bit of know-how

Step 1: You MUST be bootloader unlocked
-Start by downloading the relevant recovery ramdisk for your variant the AND magisk manager below
Step 2:
-Install the magisk manager
Step 3:
-Copy the recovery ramdisk to a folder with fastboot. Those with environment set up for adb/fastboot can ignore this step.
Step 4:
-Reboot your device to the bootloader. This is accomplished easiest with the adb reboot bootloader command. If you would like to gracefully put the device in bootloader mode, simply power off the device, remove all USB cables from it, but make sure one is plugged into your PC. Once the device is fully powered off, hold down the volume-DOWN key and then press and hold the power button and IMMEDIATELY plug the USB-C cable into the phone.
Step 5:
-Once the device is in bootloader and connected to the PC, run the command "fastboot flash recovery_ramdisk recovery_ramdiskMagiskVARIANT" with VARIANT being whatever ramdisk you downloaded. For example with AL00 you would input "fastboot flash recovery_ramdisk recovery_ramdiskMagiskAL00.img"
Step 6:
-Run the command "fastboot reboot" and immediately disconnect the USB-C cable from the phone. At this point you will want to hold down VOLUME-UP until the "device is booting" message is displayed.
Step 7:
-Once the system is booted, open magisk manager and profit.

Those who have rooted their phones. Can you guys still use Mobile Banking apps with no problem as well as finger print scanner?

Thanks man... Working good here! I did notice that EMUI update wants to fix some files. It says unauthorized files to some apps have been changed. Is it ok to let system EMUI update again?

Thank you freeza!

I saw you didn't have a link to the patched L29 so I patched mine and everything is perfect.
If anybody wants to use it or if you want to link it on the OT, it's fine.

How did you unlock the bootloader for L29?. I am using L29 but on mine the oem unlock is grayed under developer options.

It says that cause it detected root. Even if you choose to let it update, it will fail since the patched ramdisk replaces the recovery.

That's what happened to me the first time. I think I didn't let go of the volume up button sooner the first time...

    I know this is probably a dumb question but what about OTA updates (or any updates) after rooting?
    Yeah you can. Just flash back the stock Ramdisk, take the update, then flash the magisk Ramdisk again.

    Huawei officially stopped giving out bootloader unlocking codes. Period. Full stop. The only way the dubious sites like funky monkey and other rip off sites are getting the codes for you are through some of the greedy Huawei employees who have access to the phone services to provide the codes. These people join with the other rip-off sites like funky to send you the codes. They are expensive, because people rushing to unlock and willing to pay any money. Part of the mponey goes to the leaking employee and part to the rip-off sites.

    It was not like this before. XDA initially was a dedicated community on giving tutorials and contributions towards making the best of our phones. But with more companies blocking bootloader unlocking, everyone started to become greedy. We already paid so much for this Mate 20X and still willing to pay to get the unlocking codes to rip off sites?

    Even after rooting, there is no proper support for this phone with other apps because of the locked bootloader limitations. Developers can't freely experiment and tinker with this phone because the codes were expensive once, and now there are no more codes, possibly because the employees concerned were fired and these rip-off sites are unable to get the codes from them.

    Even custom roms do not have support for this device, or at least fully working ones, because of this.

    When will you guys learn? Wake up. Don't fall prey to the scams. Don't pay just because you can and promote this new trend.

    The only lesson I learnt is to do research next time BEFORE buying a phone and make sure that bootloader unlocking is supported by the company.

    As for me, I already bought this and the only reason I wanted to root is because of removing phone-wide ads. Right now, I am okay with DNS66 which does not require root. It works well, though I need to restart the service manually Otherwise this phone is perfect, and I can always have official OTA updates without breaking anything.

    Is it possible to unroot and go back to stock with no issues after using this root method?
    Just flash back the stock ramdisk through ADB and you're good to go.
