Trying to get to version 10 on C10 region.

SOLVED.

Solution as from badamania, but I will repeat it, for people who have C10 device (R6)

- I used HiSuite Newest to rolldown to 11

- I used the package

C432

from badamania98 to downgrade to

11.0.0.230

- HiSuite Proxy 2.4.4 + HiSuite 10.0.05 + Date back to August 2023 ,Used package for C432 , 10.1.0.131

ELS-LGRP4-OVS 10.1.0.131 + ELS-N29-CUST 10.1.0.8(C432) + ELS-N29-PRELOAD 10.1.0.1(C432R6)

I only changed to R6 of preload instead of R4 but kept everything for C432 Region.

I got "Failed to update" after 99% of download.

I got the unfamous C10 version.

I did not change the date before download, becuase i started reseraching this issue later.

Now even cahnging date does not fix the issue.

Maybe I use wrong packages?

ELS-LGRP4-OVS 10.1.0.131

ELS-N29-CUST 10.1.0.6(C10)

ELS-N29-PRELOAD 10.1.0.1(C10R6)

View attachment 6106586

Edit:

Even with Changing date before download it still goes to 99% and then cannot update

Good Day

I was hoping you could assist me with downgrading to emui10. I'm currently on Ana-N09 11.0.241(C316E9R2P3). I've followed your guide with regards to solutions after February 2024. It always completes but I receive a software after 5 %. The Roms in my region are not approved (C316) so it fails all the time. I even tried the C432 files but still no hope.

Hello;

Hello, I have a P40 pro with GMS. I sold it and the buyer was supposed to create his account and then delete my transfer account. He did something wrong, I could no longer install the apk to change the account. I then decided to reinstall the GMS. Now I can't manage the downgrade. First using the previous method and now using the one from page 1.

I wanted to downgraded from EMUI12 to EMUI11.0.0.202 with HiSuite Proxy 3.3.0 and HiSuite 11.0.0.650_OVE and https://professorjtj.github.io/v2/

I set the system date to 6/2023 and the update went through 100% on the computer. However, the smartphone shows that the update was not successful. After confirmation it reboots and I'm back where I was before.

Yesterday I wanted to switch from EMUI11.0.0.230 (with dload) to 10.0.0.131, and it was exactly the same.

Does anyone have a tip why the downgrade with HiSuite Proxy doesn't work on the smartphone?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Read again on the first page: solution after February 2024
[Huawei P40 Pro Guides, News, & Discussion] groschi2:
I read the first page several times. But obviously I missed something.

Can you help me with something? I think I followed the instructions exactly.

Don’t use v2 when downgrade from 11 to 10
[Huawei P40 Pro Guides, News, & Discussion] groschi2:
I didn't even get that far. But I have now had partial success. I previously reset the smartphone to factory defaults and then tried again. The downgrade to 11.0.0.202 worked now. It's currently running on 10.1.0.131.

Yes, I have base from V1 and cust and preload from downgrade.

I'm optimistic.
[Huawei P40 Pro Guides, News, & Discussion] groschi2:
The second downgrade now also worked. Tomorrow then GMS!

Thanks for tipps!
[Huawei P40 Pro Guides, News, & Discussion] groschi2:
So, the GMS is currently running again. I'm currently in the process of reinstalling all the updates. As far as I remember, there are always warnings from Huawei Optimizer that Google Services requires too much power. So far I haven't found a way to suppress these messages. Is there a working solution to this?
[Huawei P40 Pro Guides, News, & Discussion] trungkien9x:
Hey bro.. Can you tell me your GSM installation method? I tried many ways but it didn't work. My version is 10.1.0.236.
[Huawei P40 Pro Guides, News, & Discussion] groschi2:
I come from Germany and therefore followed these German instructions.

For a P40 Pro you need 10.1.0.131

After one or more days this problem occurs, which I also had this morning and was able to solve with this:
[Huawei P40 Pro Guides, News, & Discussion] trungkien9x:
I’ve tried many times, but after reaching step 3 (uninstalling the MicroG app), I checked the accounts that were added in sections 1 and 2 of the phone settings, but they were no longer there. Before uninstalling the MicroG app, they were still visible. Later, Googlefier prompted me to install Google Play Services, but even after installation, the previously added accounts in sections 1 and 2 were still missing from the device settings. I’ve attempted this multiple times without success. Have you encountered a similar issue, and do you know of any solutions? Thank you.
[Huawei P40 Pro Guides, News, & Discussion] groschi2:
Yes, I had that effect this time too. I registered 3 times. It also ran. Also the Playstore with error messages. Then, when I proceeded to resolve the error messages, it said that the account could not be reached. Since it was evening, I gave up. The next day everything went like clockwork on the first try.

Hi, first thank you for this tutorial

I did everything right But update verification faild. Do you have any idea how to fix this ?

BTW I am right now on emui 11.0.0.208

I think the problem is with {C432R6} It is not approved for installation

ELS-N29-PRELOAD 10.1.0.1(C432R6)​

#UPDATE : Ohhh my stupidity Never Fails. I had downloaded Preload from https://professorjtj.github.io/ Instead of Downgrade Archive https://professorjtj.github.io/Downgrade/. Now the downgrade complete with success.
[Huawei P40 Pro Guides, News, & Discussion] trungkien9x:
I have one solution, and I successfully downgraded my Mate 30 Pro from EMUI 11 to EMUI 10. You can still use HiSuite Proxy 3.3.0 and HiSuite 11.0.0.650, similar to downgrading from EMUI 12 to EMUI 11. I did it, and it worked flawlessly, downgrading to EMUI 10. Give it a try and let everyone know the results.
[Huawei P40 Pro Guides, News, & Discussion] trungkien9x:
I don’t understand. Why did it work? I’ve tried many times, but it didn’t work. All the accounts I added disappeared after uninstalling the MicroG app. Can you tell me if there’s a method to remove the MicroG app while keeping the Google accounts in my device settings?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I am working on a solution with somebody right now. If you already have 260 installed and have GMS installed, just dont restore the phone to the factory settings. Other errors can be solved.

Christmas gift: How to downgrade from the last version of EMUI11

(ex: P40 Pro C432 EMUI11.0.0.260)
​

If you are on the last version of EMUI11 and cannot downgrade to EMUI10 with HiSuite Proxy you have to follow this very easy tutorial:

A. If you

have

dload firmware version for your phone type and region

1. Find and download the previous EMUI11 firmware (DLOAD format) that provides:

a. transfer data through USB cable to computer

b. HiSuite Proxy Downgrade.

It doesn't matter the R version on this step. The firmware must be for your phone type and region!!!

2. Downgrade to that firmware using DLOAD method (eRecovery or ProjectMenu).

3. After that, Downgrade to EMUI10 using HiSuite-Proxy to the firmware that allows GMS install.

B. If you

do no

t have

dload firmware version for your phone type and region

( That worked for a Mate 30 Pro C636 using C432 firmware at point 1. It is not my responsibility if it is not working on your phone)

For some region you can not find DLOAD firmware version to download. In this case I used another region DLOAD firmware but for same device.

1. Find and download the EMUI11 firmware (DLOAD format) that provides:

a. transfer data through USB cable to computer

b. HiSuite Proxy Downgrade.

It doesn't matter the R version on this step. The firmware will be for your phone type and other region ( I suggest C432)!!!

2. Downgrade to that firmware using DLOAD method (eRecovery or ProjectMenu). Your region could be changed to the new one. ( EMUI11 C636 to EMUI11 C432)

3. After that, Downgrade to EMUI10 using HiSuite-Proxy to the firmware for previous/original region that allows GMS install. After downgrade, a reset to factory setting could be requested or "low-level format" message could appear. It must be done. (EMUI11 C432 to EMUI10 C636)

Notes:

1. For P40 Pro C432, at step no. A1 use this firmware: here and for step no.A3 downgrade to 10.1.0.121.

2. DLOAD method is described: here.

3. Downgrade method A have been tried successfully on MATE 30 Pro C432 (this firmware ) and P40 Pro C432 .

4. Downgrade method B have been tried successfully on MATE 30 Pro C636 and C301with this firmware.

5. After downgrade to EMUI10 and GMS install, you have to upgrade

several times

till you get the

first

EMUI11 that provides you data transfer from computer to phone using USB cable, and after upgrade disable EMUI upgrade ( disable EMUI upgrade tutorial: here). On P40 Pro C432 will be first available firmware of 200 series.

6. HiSuite Proxy method is described here.

Yep, it works flawlessly. Merry X-mas for you Guys 😊

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

[Huawei P40 Pro Guides, News, & Discussion] badmania98:
GPay can not be used to pay through NFC. Other bank apps can. What apps would you like to run?

It will not work:

GPay – cannot pay to POS;

App Twin – will block notification;

Setting\Google\Backup – using this menu will get error ;

McDonald (depends on country and app form that it used) + Google news apps;

Gmail- black Theme is not available.

”Ok or Hey Google” command: In Google assistant you need to push the mic icon to work. It works without problems when Android Auto is running.

I managed to folllow the fix steps and the message is no longer poping up. However, I can't sign in to play store or my google account in settings and every time I try to sign in, I get an error message "Your account wasn't added, try again"

GPS version 21.06.13

Play stote version 28.3.16-12

Any clue how to fix this out!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
It is hard to say.

On the first page you have few variants and info here.

You have the last available version of EMUI. And this is not good from GMS functionality point of view.

I don't think you will get a satisfactory solution. It depends also to what apps you use. Some apps request a newer version of Play Services. But newer versions of Play Services will provide the error message " the device isn't google protect certified".
