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.

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.

Push Notifications Fix

A. There are 3 methods to have push notification:
  1. Method described in this thread. (Free of charge- using Airplane mode method- You have to make this procedure from time to time, especially after restart the phone).
  2. Method using IceBox. Video. (Free of charge- using frozen GSF, Play Store is not working, other apps related to the google services/location accuracy will not work).
  3. Method of Ilham. See the first comment on YouTube here (Not free of charge- almost all working, the tutorial is not 100% accurate on the phones made for other market than China. International market phones need additional settings, made by me). I have been using this solution since march 2021 without problems on my P40 Pro C432, with my own procedure. You can ask me on private about this one. I am the only one allowed to share it. Sample

B. In case some apps receive notifications only when the screen is ON : here.

It is not related to the EMUi Update. It is related to the Google Suite auto-update. Google Play Store is auto-update itself no matter what. But it update also Google Play services. That is the problem.
It is a fact that Google+Huawei do a lot of things to stop us running Google services on our phones. So, in my opinion EMUI updates and Google Play Services updates are not good for our phones. What version of Google Play Services is now on your phone (screenshot)?

Only this error like on first screen, no other messages. I even logged into a newly created account (in a process of installing gapps) to check that's not an account problem.

Hello there,
I have a P40 Lite (it was hard to me to found this thread cause there are 3 pages for P40, P40 Pro and P40 Lite, maybe they could be together).
I have found myself with exactly the same issue described by MiszczOszczy44.
I have followed another tutorial restarting my device after cleaning cache and data from Google Services Framework, Google Mobile Services and Google Play Store, and now push notifications concerning to Google Play Protect have came back.
May reinstall previous GMS and Google Play Store solve this issue?

    @Eini666 and @badmania98 you glorious bastards.
    EMUI downgraded to 10.1.0.121

    About to install Googlifier.

    As usual, you guys find yourselves in Prague beers on me <3
    All thanks should go to to @badmania98 I only had to downgrade and install GMS 3 days ago, so I just read the entire guide and I still remember what and how.

    Hello everybody!
    I'm here to thank @badmania98 for helping with installing notifications for GMS services for a Huawei P40 pro.
    I downgraded from EMUI 12 following the steps described on this thred. I also had a weird problem (maybe others had it) - downgrade to EMUI 10 via OTG connection from a 64gb Kingston stick didn't work - the stick was formatted correctly. It was solved by using another older 8gb stick.
    After installing the GMS services, I contacted @badmania98 who was willing to help me the same evening - the process took an hour or so, during which time thousands of steps were taken - I consider the price for the service more than fair.
    Very good communication and the best result!

    Hello there,

    I am having a bit of an issue here, maybe you can help me out.
    I had EMUI 12 - Huawei P40 Pro (factory reset) and I downloaded latest official HiSuite to downgrade to EMUI 11.

    So my info was:
    Build version: 11.0.0.249
    Model: ELS-N29
    Region: C185
    R number: R4

    Edit 1.0:
    Followed your instructions and I downloaded a DLOAD file provided by you for version 11.0.0.230 (used your C432 instead of C185) (C432E3R6P4) and now my phone info reads:

    Build: 11.0.0.230 (C185E6R4P4). There was no change in region it seems?

    THE (UPDATED) ISSUE
    I am unable to use HiSuite or OTG method for whatever reason to downgrade to EMUI 10 to install Googlifier.

    A) I tried using HiSuite Proxy for ELS-N29 C184 (R4) to roll-back to 10.1.0.114 and 10.1.0.131 both. But soon as the files are 100% downloaded I get error "Failed to update"

    B) I downloaded DLOAD for 10.1.0.131 (from your old post) --> Elsa-N29D 10.1.0.131(C185E9R4P1). But when I try to install from recovery mode I am getting: "Software install failed: incompatibility with current version)

    Please tell me what am i doing wrong here, I spent all day reading and re-reading your instructions not to be lazy but i'm hitting a wall for whatever reason....
    Which hisuite version are you using to downgrade ? Latest version V11.0.0.610 you need only do downgrade from emui 12 to latest version od emui 11 and to have latest version hisuite app on the phone.
    After that you need to uninstall hisuite from computer and install 10.1.0.550_OVE-BUN but only on computer with no upgrades of firmware in phone and computer.
    Hisuite Proxy and Hisuite 10.1.0.550 will give you possibility to downgrade from 11.0.0.230 to 11.0.0.121

    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
