It is important the firmware version also to have a good answer.

E4 vs E7 means different CUST firmware, and it is important according to EMUI version.
[Huawei P40 Pro Guides, News, & Discussion] Pazu_84:
oh ****.. so there's no way of doing this with some degree of certainty?

the cellphone info is this:

I need to know which version of hisuit should i use to rollback for emui 10, and which emui 10 version should i choose, and cust, ovs and preload versions too.
[Huawei P40 Pro Guides, News, & Discussion] Pazu_84:
also i didn't understand your answer here. So can i use dload E7 or not?

MATE 30 PRO C432

1. Downgrade from EMUI12 using HiSuite 11.0.0.610 to EMUI11

2. Use this guide (A version) to downgrade to EMUI11.0.0.220 C432 with DLOAD firmware from Notes 3.

3. Use this guide to downgrade from EMUI11.0.0.220 to EMUI10.0.0.215 (C432E6R7P1)

View attachment 5565603

4. Install GMS

5. Upgrade EMUI several times till it get back USB file transfer and Fast Charge

Firmware elements identify: no.1 here.
[Huawei P40 Pro Guides, News, & Discussion] Pazu_84:
Even with all those guides, which are undoubtedly very useful and meritory, I still don't know what versions of cust, ovs and preload to choose to asure that the downgrade to EMUI10 won't fail, which happened with me many times before.

I also still don't understand if there is any problem with dload E7 vs E4.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
MATE 30 PRO C432

I will try to explain more:

1. E1, E2. E.number means Edition of CUST related to the EMUI version (10.0, 10.1, 11, 12. )

2. for your phone we can find on firmfinder the following CUST files:

a.102.0.0.4(C432) means EMUI12 E4

b. 11.0.0.7(C432) means EMUI11 E7

c. 11.0.0.6(C432) means EMUI11 E6

d. 10.0.0.6(C432) means EMUi10.0 E6 or EMUI10.1 E6

3. If you downgrade/upgrade from/to one EMUI version to a lower/higher EMUi version, you have to change the CUST also, to be the same as EMUI version that will be installed.

That is made automatically when you use DLOAD firmware (CUST file is in dload firmware) or manually in case you use HiSuite proxy (based on experience/ existing dload firmware / previously HiSuite (no proxy) downgrade).

It is a particularity on this device: Firmware EMUI10.1 uses Base 10.1 and CUST +PRELOAD named 10.0. as you can see here.

How can I get offline packages?
[Huawei P40 Pro Guides, News, & Discussion] Pazu_84:
So.. It kinda worked.. I managed to rollback to emui 10.0.0.215, and therefore successfully install GMS, which was properly working. I then proceeded to perform several OTA firmware updates, during which i lost my GMS... (when opening play store no certification from play protect etc)

Don't know exactly where, because I never thought this would happen since I had installed GMS before and the posterior updates did not interfere with it..
[Huawei P40 Pro Guides, News, & Discussion] Bongsi:
Hello @badmania98 thank you very much again for this thread. I have GMS on my phone. 😃

As soon as I installed I have message. This device isn't Play Protect certified. I have tried some of the solutions you provided. But still getting. I am still on Emui 10.

My question is Do I need to update to Emui 12 before I fix the problem. Fix it now first or either way I can do it.

Thank you very much.
[Huawei P40 Pro Guides, News, & Discussion] Pazu_84:
@badmania98 can you help me with the same situation please? I repeated the process and it happened again.. I'm on EMUI 10.1.0.237 now and google play isn't play protect certified..

I think it can be fixed.

LE: When you (all of you guys) will understand that providing general info will receive general answers?

When you want to solve a problem provide as many info as you can:

- what is your EMUI version, phone and region (screenshot of About Phone)?

- what tools have you used before (version, type)?

- what errors have you got (in what moment, screenshots, etc)?

- what firmware (files) have you used (version, region)?

- etc.

A new alternative to install GMS here.
​

In video it is used on HarmonyOS 2.0 phone, but I think it will 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.
[Huawei P40 Pro Guides, News, & Discussion] razielmkd:

I think you are in similar situation as the one described here at no. 0 a+b.

I will take a closer look after 2 hours.

Till the:

1. Try to downgrade with HiSuite 11.0.0.610 (no proxY)

2. Find a DLOAD firmware for your phone, smaller version that you have it now (2-3 version older).

From the zip file you have to copy on the NM card the dload folder. I havent used a Card Reader, just the NM card on the phone. I connected phone to the computer and copied dload folder from computer to NM card. When you look on file manager from the phone at the NM card, you have to see, on the root of it. just the dload folder.

[Huawei P40 Pro Guides, News, & Discussion] badmania98:
This is strange with a NM card. Insert the card on the phone. Try to erase/initialize (kind of format) the card on the phone with phone tools. Connect the phone to computer, copy fload folder from computer to the NM card and try again. Try from ProjectMenu and erecovery.

If is not working try with OTG+flashdrive.

Hi. I wrote. That i have mate 30 pro.

Did A step ( you recommended to follow A step). Also you gave firmware 11.0.0.176, but it doesn't support USB connection.

So i downloaded 11.0.0.192. USB ok. But i can't downgrade to 10.****** ( 10.1*** or 10.0***) always failed at 99%.

So , may be i can use firmware earlier than 11.0.0.176? Do you have it?

It's a horror((( I've already spend a lot of time. But didn't succeed.

Hi have tho phones P40 PRO and P30 PRO, was serching how to downgrade emui to 10.x and have all.

Only this message stoping me to downgrade

- ALERT : Downgrading from Latest EMUI 11 disables your phone's Fast Charging, Fastboot, USB Connection and TestPoint.

- The only way to fix it is updating through OTA, Erecovery or Dload by memorycard to latest EMUI 11.

Is thats true any was to not have disabled usb connection, fastcharging etc. after downgrade

[Huawei P40 Pro Guides, News, & Discussion] badmania98:
What region is your P40 Pro? I had a talk to that guy from minitryofsolutions, and he told me that is necessary EMUi10.1 and USB connection for P40 Pro to change from EMUI to HarmonyOS +40 $. A you can see on first page you can solve the problem with Ugreen cable. It is important also what EMUi version is on your phone now.

If you want my opinion: dont waste your money. On HarmonyOS is no differences regarding GMS. It is the same as on EMUI.

No, I did not test TP.

There is DLOAD firmware 10.1.0.159 C185E9R6P1 https://androidhost.ru/2e2w. If I use this DLOAD firmware right now, will I have no problems?

Thanks for your time and great topic!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Yes. Big problem. Dont do this. It is not working like this. 99.99% it will not work with dload. But if it will work to write that firmware, your phone will be down.

You can try playing with similar firmware with HiSuite Proxy.

It is risky but is a chance.

Find EMUI11.0.0. 2xx C185. (first 200 series firmware). Also important are all 3 files (Base, Preload, Cust).

Hi there,

First of all big thanks for all the help that you are giving to people all over the world, it is just awesome. My full respect to your dedication!

Now to my question.

I´ve been trying to downgrade a P40 Pro but I don´t seem to manage

- I´ve tried dload with several rooms including the one you show in the links

- I´ve tried with the Hisuite that you provide and I manage to get offered the version 10.1.0.121 but

a) If I use the patched one (red icon) I get an error that says failed to install

b) if I use the green one it can´t connect to the internet when trying to upload

I´ve managed to install some 10 versions using regular HSuite like the last version (610) but once it finished the download and the install the device reboots and when verifying the update throws the uncompatible software error.

My device is

View attachment 5572527

Could it be that I am not finding the right version

I can find versions where

C432 matches

but when downloading the ROMs for dload I see that there is no room where all the e parameter do not match (for example the link that you suggest to els-nx9-10.1.0.121(C432E8R5P2).zip doesn´t work with the dload method because the E do not match with my device (e3 based on suggested updates) and R, R4?

Well, I´ll definetely appreciate some help finding the right ROM for dload or the right links to configure HiSuite Proxy for this particular device to be able to downgrade to EMUI 10 to install the GMS

Hi again and sorry to bother, it seems that is being slightly complicated for me.

Yesterday I managed to dload a 11 firmware that brought me to the 11.0.0.230. From there using the official update I´ve upgraded agan to 11.0.0.260. Interestinlgy my device has changed from R4 to R6. I guess it is not very important (attached screenshot in case)

View attachment 5573715

After that I´ve used the config you suggested for HiProxy

View attachment 5573717

The process seems to work fine and HiSuite 550 offers me the desired 10.1.0.210 version

View attachment 5573719

However, when the whole process of downloading and installing finishes. The device reboots and on the 4% of the "verifying update" I get the feared error of software install failed

View attachment 5573721

(since the R changed in my device I also tryied using the ELS-N29-PRELOAD 10.1.0.1(C432R6) with the same results)

Any idea of what could I be doing wrong? Any dload download link with 10.1.0.120 that might work in my case?

You have to read (and understand) very good my tutorial. Why did you upgraded to 260? I always said that from 11.0.0.260 you can not downgrade to EMUI10 with HiSuite Proxy. That is why I made the tutorial, and explained that you have to use DLOAD to downgrade from 11.0.0.260 to 11.0.0.230, and from 11.0.0.230 to 11.0.0.121 you have to downgrade with HiSuite proxy?

[Huawei P40 Pro Guides, News, & Discussion] badmania98:
HarmonyOS on C432?

1. You will get no benefits ( including fom GMS install point of view).

2. You need EMUI10.1 on the phone.

3. You need USB connection to computer to transfer files on the phone.

4. 40 $ to that guy that made conversion of C432 to C00.

It is possible to have NO VoLTE or other things on HarmonyOS.
[Huawei P40 Pro Guides, News, & Discussion] anyn06:
What do you mean with 40 $? Isn't there a firmware of harmonyOs on the site firmfinder?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
No. It is marked HarmonyOS ( server fault) but is 100% EMUI12.

All devices (international version, C432, C185, C636 etc.) other then C00, that have received EMUI12, have this ”HarmonyOS” files on firmfinder. But it is a server error. Actually they are EMUI12.
