I have never seen before this message. Do you use an old BETA Google Play Services version app? If yes, this is it. Beta expires.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Post a screenshot from About Phone menu.
[Huawei P40 Pro Guides, News, & Discussion] tomgaga:
No, not a beta, and updated after inatallation from googlifier.

below the details:

But I guess I'll just wait a week and if it really stops working I'll try and update again.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
As I know 21.24.56 is the last version that runs without having errors on Google Apps. You said that it is working right with frozen GFS and 22.06.18. Have you ever restarted the phone after this update to 22.06.18?

Strange.
[Huawei P40 Pro Guides, News, & Discussion] tomgaga:
Ah yes had an issue before updating the google play services, but can't remember exactly which issue.

And yes I froze GFS via adb to get the push notifications working.

But so If I hear you then another thing I should try is downgrading the play services.

I'll see in a week and inform ;-)
[Huawei P40 Pro Guides, News, & Discussion] daneed:
hi thanks for the reply. Heres the screenshot:
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I think you have to use:

1. Dload method= from 10.1.0. 399 to 10.1.0.353 ( find and download this firmware Huawei P40 lite (Nova 7i) JNY-LX1 JNY-L21 hw eu Jenny-L21A 10.1.0.353(C432E1R6P1)_Firmware_EMUI10.1.0_05016PMS.zip)

2. HiSuite Proxy method = from 10.1.0.353 to 10.0.1.136

3. install GMS

4.Upgrade back
[Huawei P40 Pro Guides, News, & Discussion] daneed:
Great will give it try and let you know. Just to check is ok then that my phone build is (C432E2R2P1) and he firmware your saying is (C432E1R6P1)?

Thanks for all your help with this!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Read my tutorial here, point A.

But you will use the firmware that I wrote to you.

On HiSuite Proxy R2 will be back.

I've tried in anyway choosing diffent version from firm finder using hi suite + hi proxy.

Hello everyone.. i've p40 lite jny-l21. I downgraded with hi-suite to 10..1.0.399. I want to install google services. but hi-suite proxy gives error. i have an otg cable. Please help me. thanks

You have the answer on this page.
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
Sorry then I didn't understand what information you need
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Go to About Phone, take a screenshot and post here. Also write the version of HiSuite that you used in that image.
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
Sorry but this first photo that i've sent above isn't it what do you've asked me?

I've used hi suite 11.0.0.510 and 11.0.0.610 (versione 10.0.0.510 is not compatible with emui 11).

Thank you ....
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
OK. I think I understand now. In your case follow this:

1. With HiSuite 11.0.0.610 downgrade from EMUI12 to EMUI11.1.0.232 (as you wrote)

2. Search, download for any EMUI11.1.0.200 series firmware, lower than 11.0.0.232.

Example:

Huawei P40 Pro+ ELS-N39 hw eu ELS-N39 11.0.0.220(C432E3R5P4)_Firmware_EMUI11.0.0_05016VMV.zip

or

Huawei P40 Pro+ ELS-N39 hw eu ELS-N39 11.0.0.211(C432E3R5P4)_Firmware_EMUI11.0.0_05016VMV.zip

or

Huawei P40 Pro+ ELS-N39 hw eu ELS-N39 11.0.0.208(C432E3R5P4)_Firmware_EMUI11.0.0_05016VBK.zip

and with DLOAD method, downgrade from EMUI11.1.0.232 to that firmware.

3. From that firmware you will use this tutorial (HiSuite proxy method) and apps attached to it + this files from firmfinder (see image) to downgrade to EMUI10.1:

View attachment 5578493

4. Install GMS

5. Upgrade back to at least EMUI11.0.0.200 series.
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
Thank you very much for the help you are giving me, I really appreciate it ...

2 things I didn't understand:

1) the firmware lower than 232 that you wrote me are those inside the hi suite folder that I download with hi proxy from firmfinder?

2) excuse the ignorance for DLOAD method what do you mean? because if by DLOAD method you mean hi proxy + hi suite I had already tried to downgrade from .223 to .180 but it still gives me the usual error that I showed you once hi suite has reached 100% download
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
1. No

2. I think you missed my first message on this thread. :)
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
Maybe I've understand the problem... I've done downgrade from 11.0.0.223 to 11.0.0.180 by hi suite + hi proxy but I've to trying it with usb how you're saying here:

https://xdaforums.com/t/badmania98-...cussion-support.4346741/page-13#post-86122137

Right?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I think you cannot transfer files from phone to computer/computer to phone after you downgrade to 11.0.0.180. If you can, go ahead with step 3.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
When you downgrade with HiSuite 11.0.0.161 from EMUI12 to EMUI11, what EMUI11 firmware is installed on your phone?
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
Maybe I did not say it clear enough. The steps I need to take are:

1) downgrade with hisuite 11.0.0.610 from emui 12 to 11.0.0.232

2) downgrade from 11.0.0.232 to 11.0.0.180 with usb and not with hi suite. I've done and usb stick with 11.0.0.180, here you are photo:

PS: the downgrade from 11.0.0.223 to 11.0.0.180 I tried to do it with hi suite + hi proxy but it gave an error so from your advice it seems to me that I understand that I have to do this via usb and not with hi suite
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Right. And not to 180. You already have 3 firmware to choose. Choose one of them. The one you can find it to download.
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
downgrade from 11.0.0.223 to what firmare if not 180? thanks
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Have you seen my message to you? There are mentioned 3 firmware.
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
perfect so with firmfinder i download 11.0.0.208 version, then I put it on usb card and i try to install it with usb and NOT WITH HI SUITE.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
No way. I cannot be more clear than that.
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
In what sense? have I sayed something wrong? I've sayed that I download 11.0.0.208 version from firmfinder because i don't understang other way to download it and put into usb card...
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
1. EMUI12 to EMUI11.0.0.232 using

HiSuite 11.0.0.610 (No proxy)

2. EMUI11.0.0.232 to EMUI11.0.0.208 or 211 or 220 using

DLOAD method

3. EMUI11.0.0. 208 or 211 or 220 to EMUI10.1 using

HiSuite Proxy
[Huawei P40 Pro Guides, News, & Discussion] MrDundee:
Exactly!

I only told you that I would have reused hi proxy with firmfinder because I don't know other methods t

o physically have the .208 version downloaded on pc

and put it on a stick. To get it then I have to do a simulation of downgrade from .223 to .208 with hi proxy

obviously knowing that it is not successful with it

;-)

Got it? :-)
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Firmware used on DLOAD method is not the same as firmware used on HiSuite.

That is why I told you to find and download the firmware for Dload method. You have the full name of the files.

I already gave you all you need. It is not important R version on DLOAD method. R3 will be restored on HiSuite Proxy part ( you have the image on my message).

So I guess I'm having the same problems as others. Since yesterday I'm getting play protect errors on google apps. Is fixing this going to require a full wipe/reset or can it be done non destructively?

I've attached the errors and versions. The phone has been great for over a year since I first put google on it.

Happy for any help!!

I have tried force closing, clearing cache etc but the problem returns immediately.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
In my opinion it is a problem with Google Play services version. It is new version, and Google made changes on it that provide errors on our phones.

It is NOT needed to downgrade and re-install GMS. You can try one of solutions presented here (V1-V4):

Downgrade in one step from the last version of EMUI, to install GMS ( P40Pro C432 with EMUI version (is lower than)

< 11.0.0.260

):

This method should be used just in case a downgrade from original HiSuite is not possible/available.

You have to follow the below tutorial + next remarks:

a. uninstall your original HiSuite from computer and phone;

b. install attached HiSuite10 on computer. HiSuite app will be installed on the phone.

Do not upgrade HiSuite.

It will ask for it. Phone will be connected to computer just after you already set attached Proxy app and start HiSuite 10 on the phone.

c. you should have free space on your computer for download the needed files( minimum 6-8 GB free on partition C:, NTFS format);

d. your phone must have the battery charged 100%;

e. after downgrade you will lose Fast Charge and connection to computer via USB cable;

f. after you install GMS, upgrade Over the Air (from phone menu) several times to the last version of EMUI, where you will get back Fast Charge and connection to computer via USB cable;

g. Pay attention to the files that you use/download from https://professorjtj.github.io/

In this tutorial it is presented just a case. Do not use the same files for every phone model or region. I can help you to choose the right files. Just let me know.

h. Dont downgrade to an intermediate firmware version.

i. HiSuite 10.1.0.550 = is no red icon on the desktop. Red icon is on HiSuite11 only. After you press setup you will start HiSuite10 from original icon.

On P40 Pro C432 use 10.1.0.131.

A video tutorial just to know how to work with this apps: here. You have to follow my written tutorial.

Hi guys and girls.

I downgraded to 10.1.0.131 to install GMS, then upgraded to 10.1.0.176 (C432E7R4P1) and I can't upgrade further. "Your software is up to date". I lost PC connectivity, so HiSuite and HiSuite Proxy isn't an option for me. eRecovery also doesn't work - "Get package info failed".

Firmware finder app also not helping, "Most likely the firmware was removed from the server".

Please help me to get it to EMUI 11 to get back fast charging and PC connectivity. At this point I stopped caring for GMS, I'll just use the phone as is for a few months and then get something with Google Certification.

I've got a 256GB USB and a OTG USB-A to USB-C cable.

I found this page, but I'm not sure if I can use P40 Pro+ FW on my P40 Pro: http://huawei-firmware.com/?q=els-&load_page=search&page=1

Try to go through Support app from app gallery (or My Huawei if you updated it). There is Support tab, scroll down and click More > its bit hidden, you have to scroll down a bit on right part of screen. Pick Update (bottom left, I have it translated so not sure if it is called that in eng version) and try to update that way. It usually works...

Hey man, first of all thank you for supporting people like this, means a lot really (I know how frustrating it can get after trying 100 times and no results)

I had everything working fine until few days ago when I reset my google account password because I am an idiot...

For whatever reason I did a factory reset on my phone, now I have:

Huawei P40 Pro

ELS-NX9

Build: 11.0.0.234 (C185E6R4P4)

I successfully downgraded to correct build in the past and managed to run Google services with no issues but for whatever reason I am now getting following error when trying to revert to needed build with OTG Update method:

"Software install failed!

Incompatability with current vesion.

Please download the correct update package."

I do not know what to do anymore, it has reached the point where I can't access some very sensitive information due to absence of apps... Please tell me what I can do or how I can get Google apps back... I would be really grateful

4. is downgrade using hisuit proxy and hisuite 10.1.0.550 directly to EMUI 10.0.0.191 (c636) and done. at this step, after downgrade to emui 10. i lost my USB connection and SUPER Charging.
