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?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You don't need special tools. You have all you need on the first page.

1. Downgrade to 10.1.0.121. Use any GMS method that you like. I used... see first page.

2. Yes. Any version higher than Emui11. 0.0.200
[Huawei P40 Pro Guides, News, & Discussion] aovivo_207:
hi there, I belive I have made a mistake doing the downgrade of my p40 lite as folow by the images atatched. I'm unable to use the usb port for transfer files, even the software uptades arent working anymore. I managed to follow this video (youtube T6BM5spiH4g) to make the flash drive work, but now i dont know wich firmare is the right for my device. I'm tryng to go back to the EMUI 11 or some EMUI 10 that alowed futher upgrades to get GMS working again. where i can find the correrct firmware for this p40 version?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You have to write the details of the initial firmware too. Your YouTube link is wrong written.
[Huawei P40 Pro Guides, News, & Discussion] aovivo_207:
i followed this video to get the usb stick working.

the image atached was before the downgrade.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Post also the firmware source or the full name of the zip file that have been used to downgrade. Too see all info of the firmware that you used.
[Huawei P40 Pro Guides, News, & Discussion] aovivo_207:
the firmware that i use to downgrade:

Jenny-L22B 10.0.1.167(C636E2R3P1)_Firmware_EMUI10.0.1_05016NLS
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You used a C636 firmware on C605 phone.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Try to find and write this one:

404 Error - Page Not Found! | Download GSM

[Huawei P40 Pro Guides, News, & Discussion] aovivo_207:
Yes, that was my mistake... there is a way to recover it? upgrading for the correct firmware? i can't handle to find the C605 firmware anywhere
[Huawei P40 Pro Guides, News, & Discussion] aovivo_207:
yes, i find only in this payed sites. but i dont trust them...

OK. I did. It was no problem.

but still get the same error while doing de upgrade
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I will take a look this afternoon.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Try this with your 10.0.1.136 firmware:

1. Copy dload folder in other place on your computer

2. Rename the folder and zip files from DLOAD folder with the names of the similar folder and zip files from C636 firmware Jenny-L22B 10.0.1.167(C636E2R3P1)

3. Copy the dload folder on the usb stick and try.

The Idea is to have a C605 firmware with a C636 firmware names of files and folder.

still failed. but I think it's made some progress. when it went to the screen of EMUI verify update, the screen flashed black after some time and then returned to the same place only with the EMUI logo and nothing else ... stayed so for a long time before giving error again. Software install failed! Get Help from: http://...

Yesterday I have tryed the eRecovery mode too, it made the full download of the 12DotSomething version and then get another error. "unable to obtain authentication information"

I have tryed all the image firmwares as well
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You can try to use a cable+ HiSuite proxy: see the cable at no. 6 here.
[Huawei P40 Pro Guides, News, & Discussion] aovivo_207:
the usb its not working, only with otg and the folder dload inside. nothing outside the phone folders is recognize too.

Hey Guys,

I just deleted by mistake my son's phone Google Play Store (P40 Lite with latest WM 12.0.0.231) , which was added two years ago and works fine but there were pop-up notifications .

So decided to fix it and wanted to be as descirbed (all google app to be deleted)..and YEAH I deleted Google play Store as well :))))))

My question is : Can I add Google Play Store app without downgrading to v10 or must do all steps explained in the first page?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
It can be done without downgrade, if you didn't reset to factory settings.
[Huawei P40 Pro Guides, News, & Discussion] toxata:
I am not sure if I understood correctly - I haven't done reset to factory setting yet, i just deleted Play Store on the phone. What I can do now? Thanks a lot!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You can install Play store again. Just the app. It is possible to receive play protect errors and try to solve them with no. 1 from here.

In theory this is the procedure.
[Huawei P40 Pro Guides, News, & Discussion] toxata:
Yes, that is what I want to do, but don't know how (from where to download the app).
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Google search for ”Google Play store apk” or go to www.apkmirror.com and search for Google Play Store.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
Hi, I hope someone can help.

I managed to downgrade to 10.1.0.131 in order to install GMS, then downloaded the package with the apps, unzipped the file and installed Backup & Restore. And here comes the weird part: the app is missing the option "restore from internal storage" when I tap on the three dots, and I cannot proceed! Am I missing something? Any suggestion would be much appreciated
[Huawei P40 Pro Guides, News, & Discussion] alberht:
Go back and open again the app. It should show up there.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
Trust me,

I tried countless times.. I even rebooted the system so many times, I don't know what (if anything) I'm doing wrong
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
What tutorial do you use?
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
Yours.

I downgraded from EMUI 12 to 11.0.0.260 with the official HiSuite release, then installed the C432E3R6P4 FW via the NV memory. Downgraded to 10.1.0.121 with the patched HiSuite and worked well, but couldn't get the Internal storage thing to work.

So I upgraded, downgraded again, this time to 10.1.0.131.. but still nothing. Crazy!
[Huawei P40 Pro Guides, News, & Discussion] thenorthfranz:
Which version of HiSuite and HiSuite Proxy are you using? I'm trying to downgrade my EMUI 11.0.0.260 to 10.1.0.121 but I get the "software install failed..." error. Also using USB Storage didn't work.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
1st you need to downgrade from 11.0.0.260 to 11.0.0.230.

Badmania98's tutorial works like a charm; you need to use the C432E3R6P4 firmware to be put in an NV or external USB memory to downgrade to 11.0.0.230. Then you can downgrade to 10.1.0.131 or 121.

But I'm still stuck because it won't show me the Internal Storage option to use the back-up
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I am talking about GMS tutorial. On 121 or 131 it should work. You did something wrong.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
Well, I simply downloaded the file with all the apps, unzipped it, and installed the first one which is the Backup & Restore. Then nothing because I'm not shown the option to install the back-up
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Nice. Not good also. No. 4 here.

But you can find many tutorials on YT regarding how to install GMS.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
I actually followed this one and this one too. They're almost identical.

But again, I'm stuck at the very first point, I mean at the very beginning of the operations. I did nothing different from the tutorial, unless I keep making some mistake after resetting the phone. But it's practically identical to what you pointed me to.

I'm confused
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Have you changed the date? Are you sure that you copy the backup in the right place? Close also internet connection.

The tutorial that I used is working. It is different in some parts.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
In the end the issue was the files had been placed "in the wrong place". Still don't know which is the right one, but I managed to complete it.

The phone has been upgraded to 11.0.0.151, but it's not showing further upgrades. Pity the USB connection is not working yet, HiSuite would have helped speed the process. I guess it's now a matter of time before the next OTA update shows up. At least, that's what I hope

Thanks for the support
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Insert the sim-card. Search again. From 11.0.0.200 you will get the USB connection back, and FastCharge.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
Just like you sais. I'm impressed, thanks a lot

Polish/German handy, all numbers and version im attaching with this conversation. I will update with USB stick and adapter usb-c.

Can you help me?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Upgrade back to the first version of EMUi11.0.0.200 series. You can use OTA or eRecovery wifi.

Then:

Downgrade, install GMS, upgrade back. Read first page.
[Huawei P40 Pro Guides, News, & Discussion] Kluiv3rt:
OTA = usb storage bigger or exactly 8 gb witg usb adapter and volume + and power ye?

ERecovery doesn't work, failed because version is no the same as installed(my version is for p40 pro?)
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
OTA= Over The Air, from phone settings search for a new EMUI version.

NX9=N29
[Huawei P40 Pro Guides, News, & Discussion] Kluiv3rt:
Only this 2 i have found: can i choose one of them, download and thats all?

Excuse me but im noob...
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
OTA: Go to phone settings/System & update/Software update. And search. With sim-card in the phone.
[Huawei P40 Pro Guides, News, & Discussion] Kluiv3rt:
You think that I havent tried this option first? 😉 "Software ist up to date, you dont need update". I can only with usb stick but when i tried with ProjectMenu there is info that "Incorrect version, Incorrect files". With this dload version..
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I think you have no ideea what to do and how to do. What dload firmware do you use?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
This is dload firmware 10.1.0.121 C432. How to use it? See first page. You can try to downgrade from EMUi10.1.0.176 to this.
[Huawei P40 Pro Guides, News, & Discussion] Kluiv3rt:
Thanks a lot. Dload was exactly for my phone.

Now im installing googlefier and then i can update with OTA(Phone Settings)?
[Huawei P40 Pro Guides, News, & Discussion] Kluiv3rt:
Now I have another Problem....

I need back my emui 12,but im only can update system with OTA to 10.1.0.176 and then im having a Info that is software "up to date". USB connection doesn't work, and I Cannot find dload update for my Phone😪I have tried 3 or 4 and always "Failure" (see screenshot).
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Read first message of this thread.
[Huawei P40 Pro Guides, News, & Discussion] Kluiv3rt:
I had, but dload files for 102 isnt so fast to find... Ok, i must stay on emui 10...
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Use any other methods, but dload.
[Huawei P40 Pro Guides, News, & Discussion] Kluiv3rt:
Mit ProjectMenu ist obly the way to make this, only this method works, but files which im downloading always "Incompatible with current version"..

Heyho,

I am kinda in a loss rn, I tried to downgrade my phone(via. Hisuite proxy), but out of my stupidity I got the wrong 10 version (ELS-N29 10.1.0.176(C432E7R4P1))

for gms. At last I found your thread and the youtube vid. about it. Rn I try to downgrade "further" with dload (usb otg) - but it is "stuck" right at the start. Since 2 hours, it says "verifying update" 0% -

Tried to find a solution on my own, but I start to get depressiv now. (cant find any solutions on google aswell :/)

I there a way to update it again, so I can start from emui 11 or 12? think everything would work again after that.

tried to update via. recovery, but it says "getting package info failed" (prob. cause of hisuite proxy).

I will let my phone use the usb otg, to maybe downgrade it again, till maybe someone answers. Maybe it will work, maybe not

[Huawei P40 Pro Guides, News, & Discussion] badmania98:
1. All upgrade methods described on first page

2. One cable from no6 here + HiSuite or HiSuite Proxy.

3. USB-C OTG+Stick + EMUi10.1.0.121 (posted few messages ago) + right method described on first page.
[Huawei P40 Pro Guides, News, & Discussion] SloppyPoyraz:
Thank you !

I am at 11.0.0.230 (C432E3R6P4) now.

Thank you again !!!, that worked :D

I am at 10.1.0.121(C432E8R6P1) now. And since I dont wanna do anything wrong now, I just ask and wait (sorry again).

To install GMS without problems,

shall I use from your first messages :

"Google Suite Install/Errors etc. ( Play store, Google Play Services, Google Account, etc.)"

No. 4 ?

Since I dont understand his language, I can only follow his steps-

is it fine to use the video from "system hacks"
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You can try anyone you want.
[Huawei P40 Pro Guides, News, & Discussion] SloppyPoyraz:
Its me again.

Is there a way to pass safetynet? Everything worked, after some errors with play services (Play protect thing.). Now everything works fine (thank you again for that. Is there a way to support you? I would like to show my appreciation :)).

so to Safetynet, I installed the Safetynet tester, after everything worked. (before installing the tester I waited till I can install without problems, no play protect problems etc. etc)- the safetynet tester says CTS profile match fail- but the rest is a success (request, signature validation, basic integrity).

Can I use Magisk for that? or can it break everything again
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
It's weird you're having problems. I had some but not for the same reasons.

Did you solve? Maybe we can help, but what model are you working on (P40, P40 Pro..)?
[Huawei P40 Pro Guides, News, & Discussion] Postmanpl:
Hi,

I dont know how, but my P40 Pro downloaded update in night (onlu download - without install). Currently i'm on 11.0.0.260, but 12.0.0.218 is in memory, ready to install. I'm going to downgrade (for GMS), but what with that new update downloaded, should i install or just ignore that?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You have to ignore it if you want to downgrade. It is possible to auto-upgrade itself in background, so hurry up with downgrade. On first page you have the procedure to prevent/disable EMUI upgrade.
[Huawei P40 Pro Guides, News, & Discussion] L.V.:
If you want to install your GMS, you need to downgrade to 11.0.0.230 first (using Badmania98's procedure) and then to 10.1.0.131 using HiProxy + a patched version of HiSuite

Once you understand how it works, it's very easy. Did this no less than 4 times; now I'm fairly quick

[Huawei P40 Pro Guides, News, & Discussion] L.V.:
If you use the official HiSuite, you can downgrade to 11.0.0.260, then you need the dload folder with the right file to download to 11.0.0.230 and finally you can downgrade to 10.1.0.131 using HiProxy + a patched version of HiSuite

Is there a way to stop GMS updating to 21.39.18? I installed the gms rule 3.5(21.39.16) with version 040408 but after a while it's automatically updated to 21.39.18 again and eventually get play protect error again. I've tried restrict play services background data. not allow run in background/auto launch but it's still keep updating to latest version

Any advice will be greatly appreciated. Thanks before
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
The last play services version that you can use is 21.24.56. You must change settings to the Play Store also.
[Huawei P40 Pro Guides, News, & Discussion] luisvalino:
Great job !! @badmania98

One more thing:

According to what I read in the post, in order to avoid Google Play Protect errors, you have to go back to the Google Play Services app to an old version such as 21.24.56 ... but in that version there are some Google apps that do not work right and they ask for an update of the GPS to the most recent version, with which it is possible that the Play Protect errors will appear again.

Is it right ?

⚠️ At Eloy Gomez tutorial -> here -> He says that the latest version of the Google Play Services that does not have Play Protect auto-detection is the 21.15
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Do not confuse all user with users that use GFS. FIX.
[Huawei P40 Pro Guides, News, & Discussion] sky360:
i want to say big thanks to @badmania98 for helping me get google services on my p40 pro. i was very confused by the process and all the different guides out there and they made this painful process quite easy for me, thanks.
[Huawei P40 Pro Guides, News, & Discussion] luisvalino:
I don't understand you. I'm talking about Google Play Protect errors, the same Eloy Gomez video link you posted at the beginning of this thread -> post #4, B. V1

Eloy Gomez tells the same I wrote it on my last post -> Video 10:07 min -> that you need to downgrade to GPS v.21.15 in order to not have Play Protect errors.

Please @badmania98 -> Check it !!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
But you understand me very well. Eloy Gomez is talking about phones without GFS.fix, at that moment, as many people have. And he recommend 21.15.13.

I am talking from my experience, having a phone with gfx.fix installed, and after 3 days that I spent trying all versions of Play Services from 21.21.16 to the last one. And the last one that is good is 21.24.56, and not because it auto-updates (because it doesn't). It is the last one that will provide no errors.

You can try yourself and post your results. It is also up to the phone region and model. My phone is P40 Pro C432.
[Huawei P40 Pro Guides, News, & Discussion] luisvalino:
Let's see, I think I'm trying to understand you. I have the Google Services Framework fixed to get push notifications like in the P40 tutorial in XDA without having to freeze it, you mean that?

I understand that you mean that this tutorial by Eloy Gomez to avoid Play Protect errors does it without having fixed the GSF problem, right?

So is it possible that this Eloy Gomez tutorial to avoid Play Protect errors doesn't work on my Mate 30 Pro ??

My mate 30 Pro is a LIO-AN00 chinese version but I'm using in Spain.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Right.

In addition he use other settings then I use.

My work is related to push notification fix (GFS.fix). When I try something, I try having this fix installed. All members from my private group on Telegram have this fix installed. That is why I am not interested to try without the fix.
[Huawei P40 Pro Guides, News, & Discussion] luisvalino:
My Mate 30 Pro is a LIO-AN00 chinese version with Harmony OS 2.0 and I installed Google Play Services since 11 months thanks to a Eloy Gomez tutorial.

I'm using it in Spain. I have Play Protect errors each once a week or later, it depends.

And I followed XDA tutorial to get push notifications without freeze GSF.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
We 2 had many conversation about this. It is your decision, and for sure you know that the solution that you use is not permanent. And you manage it to work for a limited period of time (till get new GFS ID).

How can I help you?
