try to use Blue Mail or Outlook, or Huawei email. I know you want GMail. At least you have an alternative. What version of Google Play services is installed now? Post a screenshot.
Gotcha. See that's not the bit I'm too worried about. I use Microsoft authenticator for work and if notifications don't work, I can't use it.

Do you know of any way to get notifications working? Any alternative solution would be helpful. At this point I'm even willing to completely downgrade again and restart the process, so long notifications work :( it's so difficult without that

Absolute legend!!! Used the paid method and it only took 30 minutes for him to resolve all my issues. Well worth it, I'd suggest everyone do it. Very very helpful. Offers full support.

On my P40 Lite I got an error message "This Device Isn't Play Protect Certified". I've fixed it using "Fix GSM Play Protect Certified.7z" by ictfix.net.
Here is the fix if someone needs: http://www.mediafire.com/file/c04ajfq6j0mvwmy/Fix_GSM_Play_Protect_Certified.7z/file
I did only the last step:
1. Go to settings -> Google Play Services -> Clear Data
2. Uninstall Google Play Services
3. Install "3-GSM Play Protect certified Fix.apk"
That's it. Then I've closed Google Play Store and opened again and it works.

You can try to fix google errors with Google. play Services 21.15.13. Then try AA and Gmail.

As I wrote l already, I use other method. See my last posts.

Hi there @badmania98,

Signed up to XDA as having similar issues to most P40 Pro users. Would it be possible to share the notification fix please? I've messaged the Youtube Video owner (v3) but he hasn't replied yet and I need Authenticator for work purposes. Understand there's a cost.

Thanks so much for all your hard work and effort sharing knowledge here!!

Ok @badmania98
Thank you for posting this thread.
At the present day I received Play Portect Errors once a week or later.
I checked last Eloy Gomez tutorial.
But currently I'm using the method of delete cache & data of GSF and rebooting phone.
Wait for a few minutes and always runs good.
Currently I have got Play Services v21.39.15
And my Mate 30 Pro 5G is running with the lastest Harmony OS.

    Hello!

    Because I answered to the same questions on different threads, I decided to create this thread, where I will provide my experience to you, in one place.

    The followings messages (2-7) contain all major info and tutorials links from this thread.

    All solutions/tutorials are related to the EMUI version that is installed on your phone. Before you start using this phone and upgrade/downgrade the firmware, I suggest you to read this message and after that you can continue reading the thread.


    I am waiting for your questions. I hope that I can help. I will not answer again if I already answered and you haven't read first 7 messages of this thread. I don't like people who are more lazy than I am. :devilish:

    My Phone: P40 Pro C432 EMUI12, push notification fix installed.

    Best regards,
    Daniel

    LE: My support on XDA is free of charge. I will provide/mention free solutions. If you find something interesting on my messages you can provide a Like.
    On PM/Telegram I could provide different solutions that could be not free of charge.

    Downgrade


    IF YOU HAVE GMS ERRORS
    DO NOT RESET THE PHONE TO FACTORY SETTINGS AND DO NOT MAKE EMUI DOWNGRADE

    0. 20220315: Downgrade from EMUI12 is working with HiSuite 11.0.0.610.

    For P40 Pro C432, to downgrade:

    a. from stable EMUI12 12.0.0.218/228 to EMUI11 11.0.0.260 ( P40Pro C432), use the newest original version of HiSuite. At this moment is HiSuite_11.0.0.610_OVE. No proxy has been used.

    b. from ELS-LGRP4-OVS 11.0.0.260 to EMUI11 11.0.0.230 ( P40Pro C432) you can downgrade using the solution described here.


    1. How to solve wrong downgrade+fix USB connection to computer (P40Pro+ firmware on P40 Pro / N39 on N29)
    Here is my guide: - here.


    2. EMUI downgrade procedure chart - here.

    3. from EMUI version
    <11.0.0.260 to EMUI10.1.121( P40Pro C432) EMUI downgrade tutorial - one step : here The procedure is the same for all Huawei phones and regions. You have to use the specific files for every region and phone type. Ask on thread if you dont know what files you need.

    4. Firmware Downgrade with HiSuite proxy and Offline Packages: here (AVOID IT).

    5. HOW TO flash DLOAD FW guide: here

    6. The transfer files between Computer and phone is available on the downgraded firmware (10.1.x.x) when you use a certain USB-c to USB-c cable. In this case a UGREEN, US355, USB-C To USB-C, 3.1, Gen.2, PD, 5A, 100W, 4K, 10 Gbps cable has been used. In the same time, using the original USB cable or other ordinary USB-c to USB-C cable have not activated the file transfer.
    Harmony TP cable works also, in case your computer/laptop doesn't have USB-C port. You can build/make one (search the procedure on YouTube).

    Hello everyone,

    I want to share my experience here.

    I posted earlier a problem on xda "Can't downgrade P40 Pro ELS-N29 C432 from 11.0.0.260 to 10.1.0.131"

    I tired many solution for several days and nothing worked!
    Then I contacted badmania98 and he gave me the right and only solution to downgrade my P40 Pro from 11.0.0.260 to EMUI 10.
    He provided me with the corresponding links and gave me a step by step procedure, shown in pictures that are highlighted by numbers..
    " 1. Press this 2. insert that 3. etc... " and then he doubled check my work before I proceeded in Hisuite Proxy to make sure that the filled info about base, Cust, Preload and the software are 100% accurate.
    I was able to downgrade my P40 Pro to EMUI 10 😁

    Now here's the best part: He gave a private service and installed GSM on my phone using TeamViewer. He used his own files to install GSM on my phone... This service allowed me to have Google Push notifications working on my phone without disabling the Google Play Store 😁
    Google service is working, maps, push notifications, everything related to Google is working now as if this phone originally had Google Pre-Installed in it 😁

    It was a great service!

    Thank you so much

    Google Suite Install/Errors etc. ( Play store, Google Play Services, Google Account, etc.)

    IF YOU HAVE GMS ERRORS
    DO NOT RESET THE PHONE TO FACTORY SETTINGS AND DO NOT MAKE EMUI DOWNGRADE

    1. Play store error
    a. It can be opened but cannot be used

    If you receive just this message try Clear Cache of Google Play Store + Force stop, then start Store again. Do not clear data.

    Screenshot_20211013_113641_com.android.vending.jpg

    b. 20211113 Errors: If the previous doesn't work try this (read below first).
    1. V1 - EloYGomeZTv
    2. V2 - Renz Dagz TV ,
    3. V3 -System Hacks
    4. V4 - GSM Fix/ ictfix

    Many phones with GMS installed have now ( since 20211113) that error message when you open Google Apps. Many of you think that a downgrade of EMUI and a reinstall of GMS is needed. No EMUI downgrade is needed. In previous links (V1-V4) you will find 4 solutions to have a GMS working. Unfortunately they use old versions of Google Play Services. The newest version is used in V1. Some apps (Android Auto, etc.) will need a newer versions of Google Play Services than those presented in tutorials. I tried different solutions and files and I have to say that the last version of working Play Services is:
    - for MateXS: 21.15.13
    - other phones: 21.24.56
    Using a newer version will get the error.
    Also a simple clear data/force stop/update or other changes made on Google Play Services file could get future errors.

    c. The fix A.3 from here solves all this problems and solves also many incompatibilities.
    My phone has not been affected: Demo

    2. Change/add Google account/password after GMS install - files in description: Tutorial - EloYGomeZTv

    3. Googlefier on 2022 - solve step 1 error : here.

    4. I used this method to install GMS: here.
    You can use any other method. YouTube is full of them. One of them is Googlefier.

    5. A new alternative to install GMS here.. In video it is used on HarmonyOS 2.0 phone, but I think it might work on EMUI10 (that allows GMS install) too. It seems to be more simple than Googlefier and it has fixed also te year 2022 bug of Googlefier.
