Hi everyone!!! I have P40 pro (C432) R6.

With the help of @badmania98 's instuctions i downgrade from emui 12 to 11 and then to 10.1.0.131

I installed gms with googlefier everything ok.

My problem is that i have tried everything to update from 10.1.0.131 to 11 and 12 without wiping my data because i lose gms and i cant do it.

I tried with otg, proxy and erecovery. every time it wipes my data and i lose gms.

I also tried to flash (with proxy) from 11 to 10.1.0.121 or 109 or 104 instead of 131 to get ota update from system settings but after downloading, it says that its incompatible and fails.

If you can tell me the right files to choose for downgrading to 10.1.0.121 or lower so i can manage to update after installing gms.

Thanks for helping!

Hello @badmania98 ,

even if this is not related to P40 pro, I try to ask you anyway an advise.

You know a lot about these procedures and maybe you can help me.

I have another Huawei model (P30 pro) that I am trying to downgrade from EMUI 10 (10.0.0.178) to 9...

Unfortunately, for EMUI 9, the only CUSTOM and PRELOAD files (for my specific model/region) available in the firm finder website, both get the "Not approved" message as in my screenshot.

So when I try to downgrade with HiSuite proxy, at the point of installation, I always get:

"Apparently Firm(s) is/are not approved for installation and proccess will most likely fail in phone." and it fails.

Is the "Not approved" rom status, the cause of all this? :(

I have tried also to tick "Force Auth Bridge" setting, but I have the same problem, with the same error message.

Official HiSuite 11/10 allowed me to downgrade from 10.1 to 10.0.0.178, but won't allow me to downgrade to 9.

Thanks for your attention.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Hi,

I know the situation. If the firmware is Not Approved it means Huawei doesnt allow to install it ( it will get different errors during or after install on the phone).

Long story short: from EMUI10 first version, Huawei also changed the structure of the firmware. That means that even if you buy a new phone with EMUI8, unlock the bootloader and root the phone, after install of EMUI10 (different firmware structure) the access to root will not be available anymore.

In my opinion it is better to stay away. You can kill your phone trying other method and forcing downgrade to EMUI9.
[Huawei P40 Pro Guides, News, & Discussion] picciotta:
Thanks for your reply and clarifications @badmania98

At this point, I have to give up.

It's a shame, I just wanted to do some tests with EMUI 9, but I realize that a proper downgrade at this point is impossibile.

p40llite there is no emui 11 firmware....how can i downgrade from 12?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
On some devices, Huawei upgraded directly from 10.0 or 10.1 to 12, without 11. In this case no EMUi11 is involved.

P40 Lite, Mate 10 Pro, are in this situation.
[Huawei P40 Pro Guides, News, & Discussion] foxy4270:
so what firmware to use to downgrade to emui 10?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
On C432 it has been used:

1. Downgrade With HiSuite Proxy from EMUi12 to 10.1.0.139

2. Downgrade with dload (firmware and method) from 10.1.0.139 to 10.0.1.136

I dont know if it is still working.

[Huawei P40 Pro Guides, News, & Discussion] xavier0606:
Hi,

After reading the beginning of the subject, I have doubts about the files and method needed...

I have 2 Huawei. P40 Pro and P40 Pro PLUS, I would like to downgrade them to EUMI 10, then install everything necessary to obtain the play store + GMS + Fixing Play Certification… GPS… I am in EMUI 11, I refused the update to EMUI 12 (harassment from Huawei every day).

I don't know which files and methods to choose.

For the 2 phones I was thinking of using these methods to Downgrade EMUI 11 to EMUI 10:

Downgrade EMUI latest Huawei Devices P40 Pro | Lite, Mate 30 Pro, NOVA 7i... Install Play Store 2021

step 1 - Downgrade

-- with these P40 Pro files:

382941 2020/06/23 ELS-N29 - C432 ELS-N29-PRELOAD 10.1.0.2(C432R5) hw-eu

382939 2020/07/07 ELS-N29 - C432 ELS-LGRP4-OVS 10.1.0.114 hw-eu

384705 2020/07/21 ELS-N29 - C432 ELS-N29-CUST 10.1.0.7(C432) hw-eu

-- with these P40Pro PLUS files:

409518 - 2020/07/01 ELS-N39 - C432 ELS-N39-PRELOAD 10.1.0.3(C432R3) hw-eu

414706 - 2020/07/01 ELS-N39 - C432 ELS-LGRP6-OVS 10.1.0.137 hw-eu

409517 - 2020/07/14 ELS-N39 - C432 ELS-N39-CUST 10.1.0.2(C432) hw-eu

step 2 - Install Play Store (GMS)

I was thinking of using this method to install the PlayStore:

Huawei P40 Pro - Install Play Store (GMS) After Downgrading

step 3 - Update Firmware

to update:

Huawei P40 Pro - How To Update Firmware After Downgrading

I found and have HiSuite_11.0.0.510_OVE and HiSuite Proxy 2.3.5.0.

Do you have any advice for choosing files version, methods, and the meaning of the steps … ?

Do I need to create a new GMAIL account?

Can I use my usual GMAIL account , and, on both phones at the same time?

Many thanks

Best regards

Xavier

For this you have to use a NM Card or an USB OTG+pen drive. The Method is described on first page.

Hello, I managed to downgrade my P40 Pro C432 to 10.1.0.121, I installed GMS, everything works fine, it upgrades itself to 10.1.0.131 on OTA, but from there it continues to work. OTA can't find an update, eRecovery can't find an update, Hisuite (Chinese version) connects via Wlan but can't find an update there either. Is there a solution to upgrade, or do I have to choose between GMS and old version vs. EMUI 12 without GMS (maybe a dload update that doesn't do a reset, or the special usb c cable you mention on the first page might help?). Thanks in advance for any help. Base: 10.1.0.131, Cust: 10.1.0.8(C432), Preload software version: 10.1.0.2(C432R5)

Thanks for the tip, I finally managed to upgrade Hisuite 11.0.0.650 (nonOVE) and proxy 3.3 via WLAN to 10.1.0.176, and from there the upgrade continues via OTA. The Hisuite version can be downloaded from the Chinese Huawei site, but I couldn't find the apk anywhere on the net, so it can only be extracted using a Huawei device connected to the computer via USB (luckily I had a P30 at home).

Hello brother. how are you? I'm new here. I posted for help after a lot of trouble. Please help me.

I am Huawei P40 Pro user. My phone was stolen. Later when I received it again it was in the same condition as the 1st picture. The preload version of the build number was missing. No updates coming. And fast charging was not working. So I try to flash 10.1.0.131 version via NM card to downgrade my phone. But later comes like picture no.2. And I don't do anything. Later the phone became like the picture no. 3. Since then the phone has been like this. I can't turn it on. Can't fix it in any way.

Please help me properly how to solve this.

Hi,

I'm new here, so far I used an older method + store freeze on my P40 Pro.

Then I went back to factory defaults and used again the 'G' (or what its name) method, and I thank You for solving the certificates topic, I can use Play store without problem (no need for freezing),

I mean I do have a problem.

My company uses Intune, which creates a new work profile, and that does not work unfortunately. It basically creates a new play store instance (with some random id) which triggers certification issue, so registering the service cannot be finished.

Do anybody has an idea if that can be solved?

Anybody played around trying some WA?

The situation is like:

-in personal profile there is no issue, no errors

-switching to work profile, certification errors appear immediately

Thanks!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Work profile: I think it will clone all GMS apps. At least Play Store, Play Services and GSF.

Did I work on your phone?
[Huawei P40 Pro Guides, News, & Discussion] luzsi04:
Hi Badmania,

Nope, I did the stuff based on internet stuff.

So far it was okay (no work profile), and foulish of me to start from beginning, ruining the working company access, as it was just recently introduced intune with work profile, so my new attempt stopped at registration.

Do you think, it can be solved?

I remember, I found a thread here about the same issue, but without solution.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I havent a work profile to test it. I dont know what to say. The chances are minimal. I worked with Private Space that also clones GMS apps, I solved it, but is a lot of work to do and try. It was just for my info, but to do the same on other phone...it needs a lot of time to do this.
[Huawei P40 Pro Guides, News, & Discussion] luzsi04:
Okay, thanks.

It's not crucial, I was curious if someone has an idea or method.

As I saw, the work profile uses a different "google user", so it's understandable that solution for own account does not work...
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I see
[Huawei P40 Pro Guides, News, & Discussion] luzsi04:
In the meantime, registering to company network solved without too much effort.

Although the problem is, any company app can be downloaded from the "copied" Play store, which has "play protect" error.

Or if I delete gsf, store does not launch at all.

It looks logical, as initially I did not add another user to google, and I do not know how new Store handles the user/access.

or maybe it's because I have ROM 12 and you have ROM 10 in the video also because the few times I put Google Play Service on top it didn't even work for me to stop the car but instead I saw in the video that it was present for you

2. Yes= if you never upgraded to a higher version than 11.0.0.19x and downgrade and use a regular/original USB-A to USB-C cable

3. Yes = if you downgraded from ANY version of EMUi and use a USB-C to USB-C cable as the one mentioned on first page of the thread (Ugreen....). A computer/laptop with USB-C port/connector is needed.
