Hello everyone! Need some help here... I have a P40 pro (ELS-NX9) in Europe (C432) and I cannot find the firmware that I can downgrade to 10.1.0.131 to complete Googlefier. I am on 11.0.0.151 right now.
I have read and watched a number of videos and posts, but on Firmfinder there is no firmware for ELS-NX9, only ELS-N29 . I followed ICTFIX procedures and use the pack they provided for N29 to update from OTG but the phone did not allow me to install.

Is there any other way I can install Google? Very lost right now. Thanks

Really confused. You need to downgrade but you tried to update? 11.0.0.151 was the higher version on your phone? Post a screenshot of About Phone.

Sorry it was confusing, I meant downgrade over usb-c OTG file.

Current version is 11.0.0.151 and I want to downgrade to 10.1.0.131 in order to use Googlefier.

The lowest version I can downgrade from hisuite was 10.1.0.176 which failed to install GMS using Googlefier

Therefore I tried to downgrade via OTG as described by ICTfix (and I used their firmware file on their website) but it says the pack was not correct maybe because their version was for ELS-N29. The other downloadable firmwares I can find in internet are also all for ELS-N29 but not ELS-NX9.

What is now the best way I can install GMS? Thanks

Attached screenshot.

Downgrade first to 10.1.0.176 using HiSuite. After that:

You can/I suggest you to use this version with dload method (OTG).
I have the same phone.



More than that, after you install the GMS stay on that 10.1.0.121. I am on this version too.

Disable the software update app (EMUI update)

One solution to disable the software update is to disable the update program.

For this I use the ADB AppControl application, which is currently up to version 1.7.1.
The application should be downloaded and installed on the PC from this address:



In the bellow pictures: Actualizare software = Software update (search for Software Update or how it is written in your system language)

a1.jpga2..jpga3.jpga4.jpga5.jpga6.jpga7.jpg



Re-enable the software update app

Thanks for ADB AppControl application to: @Cyber.Cat

Firmware Downgrade with HiSuite proxy and Offline Packages

Thanks to: @ProfessorJTJ


In this tutorial I used firmware files for my P40 Pro C432. You have to use your firmware files according to the model and region of your phone. You have to know already how HiSuite-proxy is working.

We need to have the files on computer. Files will be downloaded during a downgrade simulation.

1. Downgrade simulation :

==================================================================
20211216 LE: now you can download the files directly from the page:
Captură de ecran 2021-12-16 230312.jpg

=================================================================




Use HiSuite proxy, choose the files from https://professorjtj.github.io/ ( www.firmfinder.ml ) and start a downgrade procedure (b). Remember your files ID . You will need them later.

1.R5.jpg2.fisiere on line.jpg


In my case IDs are:
BASE: 392311
CUST: 382942
PRELOAD: 384706

Files will be downloaded by default here:
C:\user\your user name\documents\HiSuite\ROM

When the download starts, go to that location and wait to it to be done.
C:\ partition should be NTFS formatted.

When download is done and it copy the files on the phone, copy all folders on your desired location and after that stop the downgrade process.
The partition where files will be copied should be NTFS formatted.

3.download finalizat incepere copiere.jpg4.locatie fisier si copiere.jpg


Now you have all the files on the computer for further downgrade.


2.Downgrade with HiSuite proxy and Offline Packages - Internet connection should be available.

In HiSuite Proxy, Offline Packages area, choose your files for BASE, CUST and PRELOAD, selecting the correspondent files from computer for each of them.
Loading of BASE and PRELOAD files will take some times. Be patient.

You have to insert the link for BASE, CUST and PRELOAD using your files ID, where XXXX will be replaced by the ID. The link is common to all firmware’s of any phone except the ID:

In my case:

BASE: http://update.dbankcdn.com/TDS/data/files/p3/s15//G5398/g1755/v392311/1/
CUST: http://update.dbankcdn.com/TDS/data/files/p3/s15/G5398/g1755/v382942/1/
PRELOAD: http://update.dbankcdn.com/TDS/data/files/p3/s15//G5398/g1755/v384706/1/

Set other settings as in following image.
Start the downgrade.

5.fisiere off-line2.jpg

Done.

Hello.. I'm a die hard Huawei fanboy here that's currently using Mate 20 Pro. Just got a set of Huawei P40 Pro and I'm kinda confused if doing the downgrade from my current build 11.0.0.243 (CR636) will result in loss of fast charge and data transfer. Can anybody advise?

Also, I can't seem to find the right firmware for NX9 (CR636). Anybody can advise if I should go with N29?

Thanks a lot for the help there buddies. Actually tried to use the phone without GMS but it's really not possible. Most of my company apps do not work on HMS and it's making the phone unusable and would be sad to sell a phone that I've just gotten for less than 24hrs due to this. =(

@keat007 You should go with N29. You will lost fast charge and data transfer, but after you install GMS you can upgrade your software to get fast charging and data transfer back.

CR636? Are you sure? Better post here a screenshot of About Phone menu.

HOW TO flash dload FW guide (downgrade or upgrade EMUI)

Sources for dload fw:
- https://androidhost.ru/
- https://downloadgsm.com/



„USING OTG ADAPTER or OTG CABLE + USB MEMORY STICK

1. Extract dload folder from downloaded archive and copy it to the root of your memory stick / drive >=8gb (formatted as NTFS) that will be used to upgrade.

DLOAD folder contains:
- a zip file ( Example: update_sd_base.zip)
- a folder (example ELS-N29_hw_eu) with 2 zip files inside (example: update_sd_cust_ELS-N29_hw_eu.zip and update_sd_preload_ELS-N29_hw_eu_R5.zip)

I made a video here.

2. BACKUP your stuffs if you haven't done yet

3. Factory Reset your phone (optional) and POWER it OFF

4. Insert your OTG + memory stick / drive with the correct firmware on it (dload folder with all 3 zips inside)

5. Press Power button AND VOLUME + and as it vibrates and shows Huawei + Android logo WAIT FOR 5-6 seconds and release buttons, and the phone will enter in eRecovery mode. When in menu, select Update mode, then select Memory card/OTG update mode and it should start the update.

USING Huawei NM Card

1. Extract dload folder from downloaded archive above and copy it to your Huawei NM Card

2. BACKUP your stuffs if you haven't done yet

3. Factory Reset your phone (optional) and POWER it OFF

4. Press Power button AND vOLUME + and as it vibrates and shows Huawei + Android logo WAIT FOR 5-6 seconds and release buttons, and the phone will enter in eRecovery mode. When in menu, select Update mode, then select Memory card/OTG update mode and it should start the update.

OR

If you want to do it from sistem after you've made your backup and had an factory reset (optional), insert OTG + memory stick / drive OR copy dload folder with all 3 zips inside to your Huawei NM Card and dial this on dialer *#*#2846579#*#* and select 4.Software Update then 1.Memory card Upgrade . If your inserted card / memory stick or USB drive or Huawei NM Card it's recognised and contains the right files, phone will restart and start flashing the firmware. At the end when it's restarting after succesfully flashed firmware, you can remove the OTG (if you used one).

How to check for update using eRecovery:

In order to acces eRecovery (using this method in order to update WON'T wipe your phone data, it's acting like an normal OTA), follow these steps:
1. Power OFF your device
2. Press Power button AND vOLUME + and as it vibrates and shows Huawei + Android logo WAIT FOR 5-6 seconds and release buttons, and the phone will enter in eRecovery mode. When in menu, select Update mode, then select Memory card/OTG update mode and it should start the update.
3. When in menu, select Update mode, then select eRecovery mode then Update and recover system then Download update and recover. Connect it to Wi-Fi and it should start the update. If it's still the version you're atm, you can hit Cancel and then Restart. If it's a newer version than the one installed, let it download and update. At the end, it will restart to system.„

Thanks to @SilviuO

Thanks Daniel for your help today. I don't think I realised the potential of the phone until you installed the Ilham method on it.

I was originally using a method off of YouTube and a frozen GSF to get notifications, but this came with its own issues and a lot of functions/apps did not work. Since you fixed GMS today, everything works as it should and I am able to use apps I'd given up on - being able to use Play Store again rather than Aurora is great!

If anyone's considering whether you should go the Ilham route, then just do it. The phone feels completely different and seeing how little you pay for it, Daniel installs it for you and makes sure it's working + gives you advice on how to get the best out of it.

Thanks ever so much for your help today.

    It is not important to me. After that, I use my (paid) procedure to fix any errors. For you...I dont know.

    LE: I never installed GMS with googlefier.
    Successfully installed GMS and upgraded EMUI to latest version and fixed some issues mentioned in previous comments. For now it works without any problems, updated also GMS to 21.24.56. Also Android Auto works now after requested app update.
    Thank you @badmania98 for your help and clear instructions for every issue.

    Hi badmania98,
    Thanks for your thread - a lot of great info here. Currently I'm on 12.0.0.246(C432E3R4P5) and I'm thinkg about downgrade to the oldest firmware that was ever released (I guess it's ELS-LGRP4-OVS 10.1.0.114), install GMS and update through OTA.

    I can use Chimera Mobile Phone Utility or SigmaKey (have you heard about them?) to allow downgrade by the "Disable FW version and compatibility check (enable downgrade) function under "Modify Oeminfo" tab. Didn't try that yet but I'm desprate to install Google Services on my P40 PRO.

    I read many of your posts but still have some questions:
    1. Which is the best method to install GMS on 10.1.0.114?
    2. Can I update through OTA to the newest EMUI12 build or should I stop at some point?
    1
    yes, i find only in this payed sites. but i dont trust them...
    OK. I did. It was no problem.

    Google search for ”Google Play store apk” or go to www.apkmirror.com and search for Google Play Store.

    Best regards,
    Daniel

    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.


    Captură de ecran 2022-01-30 163716.jpgphoto_2022-01-21_20-02-18.jpgphoto_2022-01-21_20-03-20.jpg

    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.

    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.

    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.
    4
    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.
