P40 Pro - Downgrading Firmware For GMS - Huawei P40 Pro Questions & Answers

I'll get straight to it,
I've done this twice before, I, unfortunately, reset my password due to being hacked and had no idea how to reconnect my Google account. Wasn't long before the out-of-control spiral began and I had done a factory wipe.
Currently over 8+ hours into the descent of trying to restore GMS.
I kept the firmware I used to downgrade originally this kept failing over OTG (using a USB A to C connector) with Huawei's updates locking downgrades from Emui 12 (learned this the hard way by reading threads.)
I have seen many helpful threads from @badmania98 as well as a helpful video tutorial that references the thread posted.

[CLOSED][badmania98] Huawei P40 (Lite, Pro, Plus) Guides, News, Discussion & Support
Hello! Because I answered to the same questions on different threads, I decided to create this thread, where I will provide my experience to you, in one place. The followings messages (2-7) contain all major info and tutorials links from this...
forum.xda-developers.com
System Hacks - Video Guide
Currently Where I am at - ELS-N29 (C185R4)
I have followed the Guide/Tutorial and have made 2 of the required downgrades
EMUI 12.0.0.0 (C185) --> (Using Latest Hisuite) --> EMUI 11.0.0.260 (C185)
EMUI 11.0.0.260 (C185) --> ( Using Dload/OTG) --> EMUI 11.0.0.230 (C432) - (ROM from badmania98's Guide)
I'm stuck on the last Downgrade - Using HIsuite 11.0.0.510 - https://bit.ly/3Hwujai
EMUI 11.0.0.230 (C432) --> (Using Proxy HIsuite 11.0.0.510) --> ELS-LGRP4-OVS 10.1.0.131 / ELS-LGRP4-OVS 10.1.0.121
( Packages from https://professorjtj.github.io/ )
Despite my best efforts, I am not making headway with the final firmware downgrade.
I have tried a combination of these Roms while setting up the Hisuite proxy
Base PKG : ELS-LGRP4-OVS 10.1.0.121
CUST PKG : ELS-N29-CUST 10.1.0.8(C185) / ELS-N29-CUST 10.1.0.9(C185)
Preload PKG : ELS-N29-PRELOAD 10.1.0.1(C185R4)
Base PKG : ELS-LGRP4-OVS 10.1.0.131
CUST PKG : ELS-N29-CUST 10.1.0.8(C185) / ELS-N29-CUST 10.1.0.9(C185)
Preload PKG : ELS-N29-PRELOAD 10.1.0.1(C185R4)
in all cases, the proxy starts up fine download, hits 100%, and returns an install failed/Failed to update notification every time.
saw some more threads with some related info but I'll admit I need help at this point.

Just to confirm OTG/Dload method Fails as well with the firmware Rom I've got Elsa-N29D 10.1.0.131(C185E9R4P1)_Firmware_EMUI10.1.0_05016PVQ

You better wait for me.

already found your post below installing ELS-LGRP4-OVS 10.1.0.131 as we speak

last step is figuring out a futureproof method for GMS so when I update I don't break anything.

need help downgrading p40 lite

i have question involving firmwares:
i have a huawei p40 lite and could not find the exact firmware i was looking?
however i have found one that seems to be close/differently named because of the model code seen in settings - device info.
Are these firmware (slightly) different depending on country or continent?
If it's continent like europe, i should be ok?
I have the same issue with a p40 lite eu version (JNY-LX1) on 236, no firmware appears anywhere in Hisuite-proxy or searching on MT.
The only older firmware I managed to find is this:
https://androidhost.ru/xxX?pt=U0hGe...yTVVoNVp6MDlPdU1Ha3Q0ZHRqTTN2TW9zbnNUVXBPTT0=
Which is successfully downloaded to my pc but I have found no way to downgrade using Hisuite.
The funny thing is that the lzplay method worked a week ago (I got passed the G but then couldn't add the google account like everyone else) but now there must have been a minor update and the lzplay no longer works so need to find a way to downgrade...

the P40 Lite appears to be a different device from the P40, maybe it would be better to have a different forum for that device?

Firmware for Huawei P40 Pro Plus needed. ELS-N39

Just a couple days ago I needed to downgrade my firmware on huawei p40 pro plus to allow for GMS installation.
First time it was through firmware finder and hisuite and worked with no issues. But for some reason it seems like every firmware link on firmware finder was removed. And it comes up with a message that say firmware was deleted from the server.
If anyone knows what the issue is or could assist in anyway I'd be very grateful. Firmware I'm looking for is: fullOTA file for
ELS-LGRP6-OVS 10.1.0.132
Or Dload
ELS-N39 10.1.0.132 (C316)
Hint: Replace thread's title by Firmware needed for Huawei P40 Pro+ thus mainly owners of such device get addressed.
Thanks. I appreciate the hint

No.3 failed always failed after 100% download. and since I'm in 11.0.0.202 now, failed at 0% download.
No.7 resolved by updating firmware to 11.0.0.202

Question Installing GMS using Lazy App

Hi,
I found following guide but unfortunately download link is dead.
shorturl.at/abKW5
Do you have some info about this method? Seems promisingly.
you have plenty links on youtube and step by step instructions. youtube is usually about p40pro so search for that. There are two apps, googlifier and chinese equivalent to it, and that chinese version worked for me better as it solved notification problem. I don't have links, my phone is currently broken so I can't share.
Something that ran on P40pro with EMUI10 is not helfpful if you have a P50 xx EMUI 12 mobile. Same is true for googlefier.
Currently I'm investigating if it is possible to downgrade a P50 pocket to EMUI11 use googlefier and upgrade again.
@melo15m if you are only interrested in playstore maybe the (updated) GSpace works for you
