I am in the same situation. Using Google Pay often. But, out of interest I updated from EMUI 8.1 to EMUI 9.0 (official). Ofcouse my device bootloader is unlocked. But I am now regretting because Google Pay is not working and reports that my device is rooted. I am not able to downgrade back to EMUI 8.1. In this situation, I am preparing to move to this ROM as I could not use Google Pay already.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] ChangeToTower:
Really looking forward to receiving the update - it's a great ROM, highly appreciate your work! Thanks!

---------- Post added at 11:10 AM ---------- Previous post was at 10:48 AM ----------

I found myself in the very same situation, except that I use Samsung Pay with my Gear S3. Was stuck on EMUI 9 and could neither downgrade nor root my device (i. e. Magisk, including Magisk hide, did not work either). The only solution was to rollback using the downgrade package of funkyhuawei (with HiSuite and changing the DNS address in settings of the computer).
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] smohanv:
Hi OP

Thanks for the new update which I am looking forward now. I am planning migrate from Stock EMUI 9.0 to yours with the new version that you spoke about.

Just a question. Are you bundling with magisk v18. Thanks.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] FirstEver:
You can download the latest version! :)

Using the Direct link may cause website down due to overload, try not to use it.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] omnimax:
Yay! Is it possible to just upgrade from previous version? Like only choose system when restoring backup?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] ChangeToTower:
Good job! Just installed and everything fine so far - except that in TWRP /data partition can't be mounted/unmounted properly. Probably my fault and not coming from your ROM. Is it possible to install a custom kernel with some more governor options, like alucard or so? Another nice-to-have-feauture would be the stock P20 Pro camera with the sharpening mode.. As far as I know, the new app doesn't have that - or am I wrong? Thanks.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] FirstEver:
Are you using CLT-L09 or CLT-L29 device?

Yes, I'm still on Evira AOSP 1.0 Kernel (CLT-L09), but some users raported a bootloop after flashing this Kernel on CLT-L29 devices - this time Kernel is not included.

Is stock Huawei camera 8.1.0.300 installed after flashing my ROM? Unfortunately, I don't know how to port the latest stock camera app.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] ChangeToTower:
CLT-L29

Had the same issue after trying to flash Evira - bootloop.

Edit:

Wiped dalvik, cache, system and data, then reinstalled everything which solved the problem with /data partition.

Disregard the comment concerning the camera app. The installed one by default works fine.

That means no issues so far, except the mentioned one with NFC (that is no problem at all, as I use Samsung Gear S3).
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] FirstEver:
I have two CLT-L29 users who have installed ROM and they stuck on EMUI eRecovery and can't boot.

They can boot to bootloader and flash TWRP but it doesn't work - only EMUI eRecovery.

They also tried to use the "Download latest version and recovery" option from EMUI eRecovery but it failed.

Any solution for them?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] josdehaes:
Flash a treble 8.1 rom via fastboot. That allows unofficial twrp to boot and work. Then you can flash whatever you want. Typically you would need to do a format data. With hurupdater you could flash emui 8.1 if you want, or lineage os 15.1 (just flash)
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] ChangeToTower:
Download and install Huawei MultiTool from here:

Thank you!

I'm not using EMUI 9.0, I installed my AOSP 9.0 from EMUI 8.1 (final EMUI 9.0 wasn't available at this time).

Does it mean that after updating to official EMUI 9.0 I won't be able to use TWRP?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] whitekidney:
I've used TWRP after flashing EMUI 9 without issues to flash LOS 16. Not sure what they are on about.

There's issues mounting /data on L29 devices and decryption doesn't work, so you will have to use the stock recovery to wipe data if you need to do that when moving across ROMs.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] ChangeToTower:
Actually updating to EMUI 9 was the biggest mistake I ever did with my mobile phone, as I got stuck with FRP locked, OEM unlock greyed out, unable to root etc.. Had to rollback using funkyhuawei (paid..), i. e. HiSuite with changed DNS address on the computer. This was the only solution.

[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] ShaneMitch:
Was able to update my CLT-L04 from the 2018-10-26 version of the rom to the latest version (2018-12-10) with no issues. It wiped all system data and apps (kept photos and downloads), which is fine. I am able to restore all that from my google backup.

Just wanted to say everything seems to be working quite a bit better than in the previous rom, which is appreciated. I am no longer getting errors when trying to play Amazon Prime and Netflix, however I get a black screen with only audio. I will try to see if I can fix this by futzing around in device settings but I've tried a restart and a few other things with no luck so far.

e: googling online I found a few people that had issues with this when moving to 9.0, most of them were able to fix it by disabling colour correction settings or night mode settings/ something similar that was writing over or displaying over other apps. All the settings I could find these were disabled - is there anything you added to the kernel settings or anything you can think of that would cause these apps not to play properly?

I bricked my phone after flahing EMUI 9.0 and subsequently First Ever ROM build 10/12/2018 as well. My phone was booting in to stock eRecovery only. Ofcourse I was able to boot in to bootloader / fastboot mode. I booked appointment with Huawei recommened service centre. I wanted to give a last try and finally gave life to my phone.

Magisk 18.0 was there and wanted to install itself from a zip file but the install failed every time, but after I flashed 17.3 on it, Magisk updated itself properly to v18.0. This is a great daily driver, thank you for the hard work.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] FirstEver:
It looks like the ROM is not rooted, only Magisk Manager app is installed.

You can download the latest Magisk ZIP from Magisk Manager, but you need to flash it in TWRP.

You don't need to install the previous version :)

So I was using the 1st version of AOSP and it was running smoothly. I've tried upgrading to the 2nd one, didn't work. Did a fresh emui 8.1 install, tried again, no luck. Did another restore to emui 8.1 and installing 1st AOSP version doesn't work anymore :( So I'm back to emui 8.1...

So after about 10 data formats and reboots, I've eventually managed to boot into 2nd version of AOSP. The odd thing is I'm not seeing the update tab in settings.

Thanks for updating your ROM. The improvements are definitely noticable. I have noticed a few things that still do not work the way they should:

-Notch is still misaligned/Missing Notch awareness in OS(found a fix myself)

-Netflix is showing black screen with audio. Haven't been able to get vid working as of now.

-AOD doesn't always stay on

-Double Tap to check phone does not work at all

-Notifications are still hit and miss (partially got better after I tuned LMK)

-Dolby Atmos doesn't seem to change anything regardless of Setting

-Some Google services are not working:

--Log into Google account with Phone

--Find phone by making it ring with Google Home

--Find my Phone (in general -> Device isn't even listed)

--Device isn't listed in Google Play device manager

-I will add more if I find more.

If I can help you with the project, I'll try to do the best to my abilities, just tell me :)

Merry Christmas and Happy flashing!

I've flashed your rom 20181210 version and have been using with pleasure. Thanks!

Now I would like to have another go at the Helix engine which I have been using on my earlier device Mate 10 Pro. For this I need a kernel that does NOT do hot plugging. I understand that you have removed the Evira kernel (which DOES hot plugging) from your rom because of bootloops experienced by some users. I also understand that I am using the 4.4.10+ kernel now. I presume this is the original kernel as a part of the standard firmware Huawei put on the phone. Can you confirm this?

Do you maybe know of any kernel that I could flash on which I could disable hot plugging?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] FirstEver:
True, Evira AOSP kernel is not included, but it works on my CLT-L09 (Kernel 4.4.162).

I saw that it says to uncheck kernel partition for flashing but i'm not seeing an option to uncheck kernel, can anyone help? i've not had my phone for 3 days, i can use twrp by the way and fastboot but not any os

Did you flash the partitions manually one by one?

Make sure you follow this guide exactly

https://xdaforums.com/huawei-p20-pro/development/how-to-how-to-unbrick-clt-l29c432-t3878714

If you flashed your stock images already and hang again at bootloop, you should boot to stock recovery and do a full wipe (wipe /data partition!)

It may be possible the stock image you flashed can't mount /data due to encryption issues.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Jalac98:
You have to flash EviraKernel separately as zip directly from EviraKernel page.

there is a way.

Boot TWRP.

adb pull /data

and restore

adb push /data

delete the internal storage when you grab the files because its encrypted.

delete any keystore* gatekeeper* locksettings* files you may find in data because they use the old pass to unlock and pass is encrypted.

app settings and everything will be backed up.

internal storage can be backed up to cloud anyway.

*EDIT:

It's not a nandroid backup so be aware that after restore, it may look like everything is fine, but gapps core services will be broken.

Chat apps will not notify you in the background unless the apps are running.

So it's not a very useful backup.
