Thanks @badmania98 , I managed to solve this issue using your V3 solution.
Now seems stable, after re-installed all G apps.
The most important question now is how to prevent Google Play Store/Services to update automatically. Even before, I had set the GPS to "Don't auto-update apps", but somehow, it overrode its own setting and managed to update itself. I would like to block us permanently.
Thanks in advance,
T.
Hard to say in your conditions. I have no problems but I use this (a.3):

    Just to confirm success, I have P40 Pro updated to latest firmware 11.0.0.223 and working GMS. For half of the day now, installing everything I want.

    First i did FW downgrade to 10.1.0.131 and applying lzplay manually (you can use Goglefier, same result) using this great guide

    Then used OTA updates to get phone to latest available FW which was I think 11.0.0.198. Then used official HiSuite to apply three more updates to end with 11.0.0.223

    Then I followed this latest guide to fix GMS. I did one additional trick - disabling internet during whole process. What I learned during first try is that when you apply fixes (mainly downgrading GMS), phone sometimes manages to uprate these back. Because Play Store is by default set to update automatically. And it messes whole proces leaving you with idea that it doesnt work. It works fine, you just need to have correct versions of GMS modules.
    After finishing with video guide, I enabled internet for brief moment to load Play store. As soon as it is loaded just disable internet again. Go to settings of Play Store and in Settings > Network Preferences set Auto-update apps to Dont auto-update apps. Which hopefully stops GMS updates in background. And keeps them running till Google finds out and makes updates enforced in next version regardless of auto-update settings...

    UPDATE after week of using phone: GMS hacked in phone worked, but notifications coming through Google push services did not. I tried few available solutions but none of these did the job. At the end I used Ilham solution provided by Badmania98 in his thread. And it is working for over week now without any glitches. Notifications coming through. There are some minor issues like Gmain dark mode not working, but nothing gamebreaking. Cheers to Badmania98 for his help!

    10.0.1.100_OVE and it keeps failing after download.
    Of course it keeps failing. 10.0.1.100 is NOT USABLE anymore. Bender007 is too lazy to update it in his guide. You need a different version 10.0.1.550 (grab it here https://github.com/ProfessorJTJ/HISuite-Proxy/releases/download/2.3.5/Hisuite_10.1.0.550_OVE.zip ) this one works for HiSuiteProxy and EMUI 11 tested up to 11.0.0.203.
    However I would highly recommend AGAINST downgrading as it is dangerous and completely unneccessary if you already have GMS installed. It doesn't matter if you have the play protect error message or not, you can fix that without downgrading. There is only one case when you need to downgrade and that is if you don't have google apps installed at all.

    Says just Update failed. I hope that I identified properly my phone according to guide

    Base sw ver ELS-LGRP4-OVS 11.0.0.223
    Preload sw ver ELS-N29-PRELOAD 11.0.0.3(C432R5)
    Cust software (C432)
    My version info , The config I needed . Your phone model and build is identical to me. Preload (R4/R5/R6) does not matter, as it only differs in preinstalled apps. You can use the packs from huaweifirmware that I have in the pictures.
    Tried to downgrade to
    Emui 10 .131 - fails without downloading
    Go with 10.1.0.121 , select the combination I have above, and most of all: use 10.0.1.550 for it.

    Is Hisuite 10.0.1.100_OVE version enough to process Emui 11 firmwares?
    No. You need 10.0.1.550 for downgrades.
    UPDATE3 So Hisuite 10.0.1.100_OVE cant downgrade to Emui 10 from 11 according to this post by author of Hisuite Proxy. By using latest version of Proxy from author website and by selecting fw 11.0.0.151 I got it working and downgrading from .223 to .151 - now I hope it will be possible to go down to Emui 10 by official Hisuite.
    You can do it but you won't have USB.
    Slowly progressing back to beginning :)

    UPDATE4 sooo after successfully flashing with recommended HiSuite 10.1.0.550 and latest Proxy to fw 11.0.0.151 I ended up in eRecovery mode automatically downloading 11.0.0.202 through wifi.
    You messed it up. YOu should have gone directly to EMUI 10 using proxy. 11.0.0.151 is not suitable for downgrades, it is not a rollbackable firmware. Now your only option is for eRecovery to fix it for you as you wouldn't have USB anyway. So you go to the latest version of EMUI 11 and THEN directly go down to EMUI 10, 10.1.0.121.
    Hope it will work else I have softbricked phone...
    You will if you keep jumping corners. Don't try to experiment, this is dangerous enough already.


    Once again, if you have Google apps installed already, then it is absolutely UNNECCESSARY TO DOWNGRADE YOUR SYSTEM SOFTWARE. You can fix play protect errors very easily by just replacing an app on your phone. Why you guys would want to go through the whole downgrade process all over again is something I don't get. But, whatever you prefer :)

    You're welcome! Enjoy the experience and remember: keep it calm!
    YOu can fix almost ALL issues that can arise with GMS without ever downgrading again. This is because the only thing you really need the downgrade for is to enable elevated privileges for the google apps (this is what that weird lzplay app does) and you only need to do that once.
    The only thing you shouldn't do is a factory data reset as it would obviously wipe away these permissions too, in which case you would have to do a downgrade, but not in any other case.

    Play protect certificates keep getting invalidated from time to time, because Google is stepping up their mechanism. But see, the scene already has fixes for it. And in this case you just need to replace an app.

    Of course now, that you're doing a full downgrade+upgrade, and doing all the Googlefier stuff again, make double sure that you launched LZPLAY app as soon as it was installed as you can only do that on old versions of EMUI10. Once lzplay is loaded and given the special permissions it asks for, and googlefier having completed all of its steps, you're good to update

    But don't ever update Google Play Services as that seems to be what is breaking the Google Play certificates, causing the error messages. If you did update it anyway, you can use 7-GSM Play Protect certified Fix.apk from this pack link to fix it.
    First uninstall Google Play Services then install this replacement app.

    You just need to fix your Play certificate to stop those annoying play protect messages.
    Yes, they added additional verifications. Yes, that was probably targeted against this hack, among others.

    What you need is simply to download this pack:

    And then uninstall Google Play Services
    then install this one: 7-GSM Play Protect certified Fix.apk
    Then reboot
    And the spam notifications should be gone.
    Replacing Google Play Services with this app will force-regenerate your Play certificate,
    and this version of Google Play Services does not have the problematic check in question.
    Still you should NOT update Google Play Services as the latest version DOES have the check that will trigger this event again.

    You do NOT NEED to install anything else from this pack.
    Actually you could reupload this with only this file present.

    Yes, it is missing that option. It is not supported anymore, and if you force it, you WILL HAVE PROBLEMS.

    If you REALLY want to downgrade you can use HiSuiteProxy and an older version of HiSuite. However I don't recommend this for 3 reasons:
    - it is unneccessary
    - it is dangerous. You WILL lose USB connectivity after the upgrade, and you can only regain it when you update again to the latest system software version. And you can only do it with OTA.
    - You can very easily brick your phone if you use HiSuiteProxy as it bypasses many of the firmware validation checks
    +1 Huawei is changing things around with the latest HiSuite. Older versions will not work for software updates/downgrades for much longer.

    I got this error device not Play Store Licensed/Approved...

    This fixed my issue on p40 pro, els-n29 c432r5, emui 11.0.150

    Thank you!
