When I see 11.0.0.510 on your image it is very clear that you didn't follow my guidance.

Downgrade in one step from the last version of EMUI, to install GMS ( P40Pro C432 with EMUI version (is lower than) < 11.0.0.260):

This method should be used just in case a downgrade from original HiSuite is not possible/available.



You have to follow the below tutorial + next remarks:
a. uninstall your original HiSuite from computer and phone;

b1 install attached HiSuite 11 on computer and connect the phone to computer. HiSuite app will be installed on the phone. Do not upgrade HiSuite. It will ask for it.;
b.2 Disconnect phone from computer and uninstall HiSuite11 from computer (only). Do not touch HiSuite app from phone.
b.3 install attached HiSuite10 on computer. Do not connect the phone to computer. Do not upgrade HiSuite. It will ask for it. Phone will be connected to computer just after you already set attached Proxy app and start HiSuite 10 on the phone.

c. you should have free space on your computer for download the needed files( minimum 6-8 GB free on partition C:, NTFS format);

d. your phone must have the battery charged 100%;

e. after downgrade you will lose Fast Charge and connection to computer via USB cable;

f. after you install GMS, upgrade Over the Air (from phone menu) several times to the last version of EMUI, where you will get back Fast Charge and connection to computer via USB cable;

g. Pay attention to the files that you use/download from https://www.firmfinder.ml/ or https://professorjtj.github.io/
In this tutorial it is presented just a case. Do not use the same files for every phone model or region. I can help you to choose the right files. Just let me know.

h. Dont downgrade to an intermediate firmware version.

i. HiSuite 10.1.0.550 = is no red icon on the desktop. Red icon is on HiSuite11 only. After you press setup you will start HiSuite10 from original icon.

On P40 Pro C432 use 10.1.0.121.


A video tutorial just to know how to work with this apps: here. You have to follow my written tutorial.
Can confirm everything here works. Backdated to 10.0.1 on a P40 Pro+

Have to mention, the HiSuite Proxy that's current (3.11) blasts my computer with virus warnings and invalid file formats. The one attached to THIS POST WORKS, but when you attempt to Add ROM to HiSuite Proxy, the Github link asks you to download the newer Proxy EXE. I just copy and pasted the URLs from the File List to HiSuite Proxy and filled in the necessary fields and it all worked. Bit of extra legwork, but saves potential virus issues.

@badmania98 I would like to ask you for your help... I want to downgrade 10.1.0.399 to 10.0.1.136. Is it possible directly downgrade with HiSuite Proxy...? I went through messages and I am a little confused which preload should I use (there is no R5, just R2 or R4).
My model: JNY-LX1, P40 Lite;
Base version: JNY-LGRP2-OVS 10.1.0.399
Preload: JNY-L21-PRELOAD 10.1.0.1(C432R5)
Thank you!

I don't have a Lite phone, so I don't know at the moment if you can downgrade directly to 10.0.1.136. You can try it.
If is not working you can try first downgrade with DLOAD method to 10.1.0.364 or 353, then continue with HiSuite proxy to 10.0.1.136.

For sure you can use R2 on PRELOAD .

I tried, but unfortunately installation failed. Downloading and installation were done succesfully, but then I got message on the phone that it failed. I am also not able to try with DLOAD method, because I do not have NM card and with OTG cable it does not work. Tried with different USB, but device cannot recognize them.
Do you know, if there is any other option that I can try?

I think you have to see how to use OTG USB-C adapter + flash drive. 8GB minimum, NTFS, DLOAD folder on it. See first page.

Thank you for all these informations for my Huawei Mate Xs. Tried to roll back EMUI 11 to EMUI 10 with HiSuite Proxy.
I completed the process for a good part, HiSuite Proxy rolled back the files. Then, I began to download the old version from patched HiSuite. But after 99% downloaded, the process failed to complete download ("update failed"). I used my original Huawei cable, retried but still failed... Firewall was clear.
An idea?

The update package does not exist... I am afraid that something with connection is not ok. Also under files usb drive is not recognized.
Connect your phone to computer. Activate file transfer. try to copy a file from computer to phone. It works? If not, you dont have USB connection (firmware is to low).
If it works, post here the name of the zip file of the dload firmware. Post here an image with the content of the zip file.

    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.

    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.

    I have to mention that on the @MiszczOszczy44 I have installed the most advanced push notification fix (paid version). This procedure will fix push notifications and other/many incompatibilities.
