Heyho,

I am kinda in a loss rn, I tried to downgrade my phone(via. Hisuite proxy), but out of my stupidity I got the wrong 10 version (ELS-N29 10.1.0.176(C432E7R4P1))
for gms. At last I found your thread and the youtube vid. about it. Rn I try to downgrade "further" with dload (usb otg) - but it is "stuck" right at the start. Since 2 hours, it says "verifying update" 0% -

Tried to find a solution on my own, but I start to get depressiv now. (cant find any solutions on google aswell :/)
I there a way to update it again, so I can start from emui 11 or 12? think everything would work again after that.
tried to update via. recovery, but it says "getting package info failed" (prob. cause of hisuite proxy).
I will let my phone use the usb otg, to maybe downgrade it again, till maybe someone answers. Maybe it will work, maybe not

Thank you again !!!, that worked :D

I am at 10.1.0.121(C432E8R6P1) now. And since I dont wanna do anything wrong now, I just ask and wait (sorry again).
To install GMS without problems,
shall I use from your first messages :
"Google Suite Install/Errors etc. ( Play store, Google Play Services, Google Account, etc.)"
No. 4 ?

Since I dont understand his language, I can only follow his steps-
is it fine to use the video from "system hacks"

Its me again.

Is there a way to pass safetynet? Everything worked, after some errors with play services (Play protect thing.). Now everything works fine (thank you again for that. Is there a way to support you? I would like to show my appreciation :)).

so to Safetynet, I installed the Safetynet tester, after everything worked. (before installing the tester I waited till I can install without problems, no play protect problems etc. etc)- the safetynet tester says CTS profile match fail- but the rest is a success (request, signature validation, basic integrity).

Can I use Magisk for that? or can it break everything again

Mit ProjectMenu ist obly the way to make this, only this method works, but files which im downloading always "Incompatible with current version"..
It's weird you're having problems. I had some but not for the same reasons.

Did you solve? Maybe we can help, but what model are you working on (P40, P40 Pro..)?

Hi,
I dont know how, but my P40 Pro downloaded update in night (onlu download - without install). Currently i'm on 11.0.0.260, but 12.0.0.218 is in memory, ready to install. I'm going to downgrade (for GMS), but what with that new update downloaded, should i install or just ignore that?

You have to ignore it if you want to downgrade. It is possible to auto-upgrade itself in background, so hurry up with downgrade. On first page you have the procedure to prevent/disable EMUI upgrade.

If you want to install your GMS, you need to downgrade to 11.0.0.230 first (using Badmania98's procedure) and then to 10.1.0.131 using HiProxy + a patched version of HiSuite

Once you understand how it works, it's very easy. Did this no less than 4 times; now I'm fairly quick

Anyone point me to the starting point here? I cant find any info regarding downgrading from my build no. Is it possible or not? I dont want to mess it all up, as I dont have another phone to use.

If you use the official HiSuite, you can downgrade to 11.0.0.260, then you need the dload folder with the right file to download to 11.0.0.230 and finally you can downgrade to 10.1.0.131 using HiProxy + a patched version of HiSuite

    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.

    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.
