Okay, Nothing works, hisuite might work but I don't have a pc at hand ATM, and I can only dload, (I tried Huawei support app and erecovery) probably dload is my last option and I don't really know if it removes GMS or not, also I have noticed that the data for system update is 0 bytes which is wierd, i might need an apk for Huawei update with correct signatures.
[Huawei P40 Pro Guides, News, & Discussion] TCD28:
My answer to those questions :​

First thing is installation thru adb won't fix any issues that you already have like downgrading an app, that's only possible with debug or downgradble apps.

Second you can infact automate the process with adb, but not everyone is going to have a pc in hand neither, not to mention so processes (testing play store, force stopping untill its gray etc) those can not be programmed by a script.
[Huawei P40 Pro Guides, News, & Discussion] TCD28:
Possible but may include a fee

There is something called "rebranding" that is basically changing the actual serial number of the phone in the oeminfo (like anx-l29 to anx-al00) and after conversion to Chinese version you can install harmonyos (Chinese version usually end with "00" "AL00" and some more with zeros).
[Huawei P40 Pro Guides, News, & Discussion] TCD28:
1 - No, factory reset isn't required just clear GSF's data.

2 - Make sure you uninstalled GPS.

3 - I don't get this one but here (To Disable automatic updates just go to settings/network preferences/auto-update and click on don't auto-update.)

I have the same issue.

At 11.0.0.208 I was unable to downgrade to 10.1.0.131 using HiSuiteProxy 2.4.0.0 (neither with 3.3.0) and HiSuite_10.1.0.550_OVE (neither using non OVE version). (Tried ROMs from both FirmFinders v1 and v1+downgrade archive). The problem was the same, "Insufficient storage space. Installation failed".

Tried to update via OTA to 11.0.0.208 but the problem with SystemUI storage access persisted, tried to update to 11.0.0.260, nothing changed.

Updated to 12.0.0.218 (c432 e3 r5 p5) and the issue with storage access was solved.

Model: els-nx9, p40 pro

Im scared that if I will try again to downgrade to 12.0.0.218->11.0.0.208 I will have the same problem with storage access on my phone.

Is it possible to downgrade to another 11.xxx EMUI (different to 11.0.0.208) and then from it, downgrade to 10.1.0.131?
[Huawei P40 Pro Guides, News, & Discussion] tysjfghgffdh:
Yep, I am in exactly the same position.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Maybe Huawei made some changes in last few days and this is why you get this errors. Last downgrade (not for my phone) that I did was last Sunday without errors
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Yes it is possible.
[Huawei P40 Pro Guides, News, & Discussion] pepo.k:
thanks for info!

Anybody here with positive feedback about harmony install on p40?
[Huawei P40 Pro Guides, News, & Discussion] pepo.k:
still the question here, what would be all the force-to-stop command over adb.

By me the clicking on screen does not work at. It always stay re-activates "in a milisecond".

How would be the way over debug? This I hav not tried ever yet. Any tutorial?
[Huawei P40 Pro Guides, News, & Discussion] pepo.k:
here to question 2. What is then the right procedure? When I can not even force-to-stop the play services. It does not matter or it does. Shall I proceed?

Later at the question 2.a - ? how to overcome the stuck point, where I got comment "Unable to install. There is already a newer version of this app on your device.", when installing the "1.apk"? The same happenes also at "4. play store".
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I am reading and I am wondering. Go ahead guys.
[Huawei P40 Pro Guides, News, & Discussion] pepo.k:
before I get into play store settings and disable the auto-update, the play store already initiates update process. It is all too slow.

Also the play protect should be also disabled, shouldn't it?

What is the hack here around?
[Huawei P40 Pro Guides, News, & Discussion] pepo.k:
So one small update, I got able to force stop play-services app and also to install (downgrade) an older version of the app. Same also the play store.

The hack was that I deactivated app twin feature. The hint I found under comments in youtube. - This info is unfortunately missing here on XDA in your first pages. I would suggest you could update the pages to include this info.

I have also tried the method following the videos acc. to post #4, section B - V1,V2. Multiple times, but no luck.

I assume these 2 methods do not work anymore. - Or can anybody confirm, this workaround is still valid?
[Huawei P40 Pro Guides, News, & Discussion] pepo.k:
I tried to clear GSF data ... Do not know, but for me it is not changing... It gets clear for certain time in the deviceID app, but after I proceed with the methods to get rid of play protect errors, it always comes back the same ID. Any hint?

I am lazy to start with googlefier from scratch, but it looks there is no other free solution.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
It is well known this thing. All apps/functions that clone PlayServices or GSF have this behavior. App Twin also. In my private support group all members know about that.

You guys are talking about very old things as they are new, and my time is limited and expensive to answer to basic or non-sense questions/ideas.

I will never pretend that on my thread is all that I know regarding this phones or contains all info regarding them. the first message of the thread mentions that.

And you are very sensitive regarding help. I know you are scared to get access to your computer with its very important data (for you) and you want all for free. Very understandable thoughts. But sometimes it is worthless for the one who can solve the problem, because in this days, fixing Huawei problems it is not a 1, 2, 3, steps written on a guide. It needs more than that. You have to react to any error in the spot based on your experiences. And it takes a lot of time. And the time the most valuable and limited resources. If you have a lot of time (in your opinion) go ahead and read and try. Or find somebody who can solve your problem in few hours for free as you want. A relative or a friend maybe that you trust on him/her.
[Huawei P40 Pro Guides, News, & Discussion] espilya:
Seems that I was tired when I tested it, because updating to 12.0.0.218 did not solve the issue with storage. When I try to take a screenshot I get the same error

Hm. I will like to see the process. Sunday I have some free time. Find me in private writing me a private message.
[Huawei P40 Pro Guides, News, & Discussion] espilya:
Solved the issue using factory reset. then downgraded to 11.**.260 without issues and working storage (camera, screenshots, etc).

I will try to downgrade to <11.**.260 later.
[Huawei P40 Pro Guides, News, & Discussion] TCD28:
I already know how all this works, and I've seen many guides including Chinese ones, even Chinese forms, the problem is people think that it's just a guide with steps but nope that are no steps, you either know what's going on or just use a automated app like googlefier which I did talk with the developer a couple of weeks ago and he did mention that he will update his app, i don't know what he is gonna change but I think it's better for people to wait instead talk about stuff they don't understand.

But that's just life, people have other things to worry about and can't know anything about all this.
[Huawei P40 Pro Guides, News, & Discussion] TCD28:
By the way sorry for asking, but I have a quick question about DLOAD I know it deletes all data, but does it delete the system partition as well? Because I don't wanna waste time by updating using dload and having to go back.

If not I am gonna use hisuite instead.

Thanks.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Read this original doc from Huawei, as example:
[Huawei P40 Pro Guides, News, & Discussion] TCD28:
It's just a guide on how to dload, and mentions "deletes user data" which is isn't what I want and I am guessing that the system partition is included and it removes the GMS compatibly.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
GMS means few files installed by the user in this case. So...

LE: You are right . There is something changed at system partition level, and if it is ”broken”, the installed GMS apps will get error.

Tried dload method from 10.1.0.176 and 10.1.0.154 (cant go to lower versions using proxy), but was unable to downgrade using dload :(

Spoiler content hidden.
[Huawei P40 Pro Guides, News, & Discussion] SorrowGN:
Had the same issue with you (except I have R5 not R6) and flashed with OTG dload this (Huawei_P40_Pro_ELS-NX9_10.1.0.121_(C432E8R5P2).zip).

This was the only one that I could flash to downgrade from 10.1.0.176 using dload.

Everything else was failing (Software Update Failed).

So my solution for ELS-N29 C432 right now is:

Use @badmania98 's guide the part that describes downgrade after May 2023 till downgrade to EMUI 11.0.0.202 and from there downgrade using Proxy and HiSuite (versions described from badmania98) to EMUI 10.1.0.176. From there dload with OTG or NM to version 10.1.0.121 using the file from the link above.

"Software install failed"

Tried to downgrade with dload from 10.1.0.176 R5 using (Huawei_P40_Pro_ELS-NX9_10.1.0.121_(C432E8R5P2).zip).

The dload folder is placed in the root of the USB flash driver (using 57gb SanDisk drive. Will try later with other usb drives). What are my other options to explore and to try to downgrade to 10.1.0.121 / 10.1.0.131 ?

I also noticed that the phone is writing data (creating folders like: Alarms,Android,DCIM,Download,Huawei,Movies,Music, etc) into the USB flash driver.

Can this cause the problem? Should I put the usb drive in only-read mode?
[Huawei P40 Pro Guides, News, & Discussion] espilya:
I finally downgraded to 10.1.0.121 (Huawei_P40_Pro_ELS-NX9_10.1.0.121_(C432E8R5P2).zip) from 10.1.0.176 (С432E8R5P2). Seems that the promblem was in my OTG type-C adapter.

At first I tried with one USB driver, then with a second USB driver but using the same adapter, and at the end I used another USB driver with built-in OTG type-C adapter (one side with USB type-A, the other with USB type-C). The last one worked and I finally saw "Verifying Update" and then "Installing" on my phone.

So if you do not see "Verifying Update" and only see the "Huawei" text, then probably you need to use another adapter or usb.

Thanks for everyone who helped me.

Hello, short question as I did not find a solution to my specific issue in this thread. I own a P40 pro plus (N39/C432) and plan to install GMS. Downgrading to 11.0.0.202 went fine so far but I am now stuck downgrading to 10.1.0.132 because I did not find a proper firmware file with my region code (but for C636 and C185). @badmania98 you mentioned the possibility (yet not entirely safe) during the dload downgrade sequence to use a different region file and then go back to the right one while further downgrading. In my case it would be the final downgrading step before installing GMS, do you think, it will work? And can I go back to the correct region when upgrading again?

Maybe this question was already answered but I really did not find anything here.

Thanks a lot!

I am trying to to downgrade my P40 Pro (C185) to EMUI 10.

I was able to downgrade it to version 11.0.0.230 (C185E6R4P4)

However, I can't get it to downgrade to emui 10, using Hisuite-Proxy.

It downloads the firmwares with no issue, but once the phone restarts to install, it gives an error saying the firmware can't be updated.

Can anyone please guide me to the right way?

Guys, I have just verified ”Solution after may 2023 from first page”. 10.1.0.131 is not approved for install anymore.

The way of espilya is still working. If all firmwares 10.1.0.xxx will have the same situation as 131, you will have to say bye bye to downgrade for GMS install.

So, for all you that have GMS already installed and have errors: dont downgrade and dont reset the phone to the factory settings.

The message regrading downgrade from the first page has been changed accordingly.

[Huawei P40 Pro Guides, News, & Discussion] SorrowGN:
Whatever you can do with 10.1.0.131 you are able with 10.1.0.121 also.

Yes you can install GMS with that software version.

Neither USB connection/fast charge nor OTA updates working.

The only way to update using Hisuite etc. is by connecting via USB-C to USB-C to your PC or by Harmony TP cable as previously explained by the creator of the thread.

OTA updates are disabled below 10.1.0.176 unfortunately.

Was this the file you downloaded ? And then flash to memory stick and flash like we do to get down a level on 11?
[Huawei P40 Pro Guides, News, & Discussion] SorrowGN:
As you mentioned you have the P40 Pro Plus.

The file I used to dload is for P40 Pro, as I am aware of. I don't know if it also works and is safe for your device.

The file I used was the version 10.1.0.121 from 10.1.0.176.

Be careful you cannot use dload to switch between EMUI versions 11 -> 10 or backwards. Only from same EMUI version 10.... -> 10.... / 11.... -> 11.... etc.

OTA updates do not work bellow 10.1.0.176 neither USB file transfer/fast charge.

To update from 10.1.0.121 / .131 etc. you need USB-C to USB-C connection with your PC/Laptop or Harmony TP cable so your device to be recognized and connected to update through Hisuite.

I strongly advise you to read all the thread mostly the main guide from @badmania98 on first page.

Experience among different users may vary and put your device to danger if you don't know what to do!!
