It depends on your data partition. If you've decrypted the data partition, you can backup and restore it.

Without Bootloader unlocked you can't flash anything.
DC Unlocker doesn't work on latest Oreo Firmwares or on PIE. It worked well on Nougat.
But Mate 9 cannot be downgraded to Android 7, this will destroy the device.
The only chance could be Funky Huawei (but you should ask by email before paying 55$) - I am not sure if its still possible.

I made a Thread on Android Hilfe de for German speaking users with credits for this new TWRP: https://www.android-hilfe.de/forum/...29-und-mha-l09-emui-9_android-pie.908543.html

Man! Thank you sooooo much for this manual! This is awesome!
I was using Google translate from German. And almost everything was translated just fine and more then enough to get this guide finished step by step.

Your welcome
Soon I have time, I plan to update the Thread with newest Magisk and some further tricks.

Does It works on p20 lite?

OpenKirin RR 7.0.1

MHA-L29 C636 - upgraded to EMUI 9.01, OpenKirin RR 7.0.1, Magisk 19.03, Busybody NDK
Reading your instructions @Tecalote and @ajsmsg78 - very keen to try and load TWRP to Erecovery with Magisk (recovery_ramdisk). Will this be possible with my RR rom?

I am not sure, if TWRP does work well with RR OS, since Open Kirin doesn't support any TWRP anymore.
You can just try. The other thing is that it's a bit tricky if you need Huawei eRecovery back on some day (for updating or restore Firmware for example)
In this case you need to Unroot, flash TWRP to recovery_ramdisk and with TWRP flashing Huawei eRecovery to erecovery_ramdisk - because eRecovery isn't flashable with Fastboot Mode.

Thanks - no problem with the Huawei recovery as I flash stock via adb if needed. I'll experiment on the weekend and post my results

It works very well, just because they say that they don't support it, it doesn't mean that it doesn't works well.
Every update that they release, I use twrp to flash the .img (but always do the wipes with stock recovery) and I flash magisk with twrp too.
I can't understand that mess from openkirin against twrp.
I have a p10, emui 9.0, using omni pie with twrp installed.

You can use twrp on erecovery partition and flash magisk, which will use recovery partition.

Yea - you get your wrist smacked if you mention the TW*P word
I installed TWRP and Magisk following the excellent guides guides here - works perfectly. I also tried the data decryption thing but that wasn't so successful - the custom ROM appeared to load but just stuck on the start animation. Huawei certainly did well with their eRecovery module - you can wreck your device and it will pull you back out of the water to try again!

You can decrypt data on emui 9 (custom roms), I did it but with OpenKirin roms it needs a bit more of work.

Thanks @sfoot13 - I might try that - do you have instructions?

Hmm let me remember...
Go to Vendor/etc …> fstab.xxxx open it and go to data line, at the end of the line you'll see the encryption, just delete it (same as image) the word "check" is the latest word that needs to be keeped.
Now go to recovery.fstab and do the same look for userdata and delete the encryption part until length=xxxx.
Look at the pictures that I attached.
After that reboot and do the wipes on stock recovery. Now try Twrp it worked for me.
Don't waste your time if you are going to use OpenKirin roms, because it didn't worked, it encrypts again the device. I have an idea about which file I need to edit but I haven't tried it yet, because I'm using Aosip.

Hope it works for you

Thanks for the info! I'm staying with OpenKirin build for now but I will try the decrypt if I move to another ROM. Much appreciated.

Anyone know if you can use this method in Emui 9.1
