There are several options

With SIM / noSIM - does not work

USB C CABLE - I don't have it

Where can I download HISUITE 10.1.1.500 without OVE?

Thank you. HiSuit and WIFI connection saw 176 updates I also wanted to ask if there is any option to make Google Assist work? It requires upgrading the Google LLC version, which will cause a problem with Google Play.?

Read first 7 messages of the thread. There you can find many things.

After upgrade to 176 insert sim card and search from Phone settings(OTA).

Good morning

I have a P40 with GPS working perfectly including updated Play Store and Play Services.

I would like to sell it by resetting it but leaving the GPS installed, is it possible without having to redo the whole procedure ?

Thanks in advance .
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You can but some info will remain even you will uninstall all personal apps. It is better to factory reset it and log off+ delete device from Huawei+Google accounts.

Good evening everyone, I have p40 Pro (c432) which I've downgraded to install GSM, all things are good (googlefier). Been working fine with a system update to 176 from 131. My only issue is I receive notifications from most apps but I don't from others like ring doorbell and banking app.

My Google play services version 20.09.14, is there a fix available please?

I tried to write dload firmware 11.0.0.2xx but USB does not connect.

Hisuite also not working due to not getting USB connect. Then I tried the video you suggested but it doesn't work.

How to solve it please help me brother. please
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Try to use HiSuite proxy and downgrade to the first EMUi11. After that with HiSuite (wifi version), try to downgrade without proxy several time. Maybe it will work as on other Mate 30 Pro.
[Huawei P40 Pro Guides, News, & Discussion] aPeN.Jr:
I will try and report for this method. thx for your reply.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Dload should work with a NM card or maybe with USB OTG+ pen Drive.

Hisuite NON-OVE ( from China Hisuite page) can be used to connect with the phone with Wi-Fi (HiSuite apk

should be sent, installed and ran on the phone first)

[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Yes, I tried on two computers with Win10, and I tried to downgrade to 11.0.0.232and 11.0.0.151, neither worked. Another information is that, first of all, there's a remind on my phone to update to 12.0.0.350, after failed downgrade, this update remind doesn't show anymore. I can only see update to 12.0.0.350 with HiSuite, but when I tried to update, it also failed.

I still cannot down grade my phone (ELS-N39) to EMUI 11, it's now running 12.0.0.350(C432E3R3P4). Could you please help me? Or do you have some hints for this problem? Thank you!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Some how you have to downgrade first to EMUi11:

v1. With HiSuite without proxy

v2. With HiSuite + proxy
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Yes, that's what I've been trying to do. But neither worked on my phone... It always shows "update failed" after downloading the ROM. I have also tried OTG or dload, It will cancled at verifying and show "install failed"...

Is there a possible reason? Or solution maybe? It drives me crazy.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
What dload firmware are you using? Post the original name of the zip/rar file.
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
I'm using the firmware you posted in the thread, from bender007, the original name is ELS-N39(c432).zip. Inside is update_sd_base.zip, update_sd_cust_ELS-N39_hw_eu.zip and update_sd_preload_ELS-N39_hw_eu_R3.zip
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
But I can not see the version
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Sorry, I don't know exactly the version. But I guess its EMUI 10, because in the download list there are only EMUI 10 ROM. Maybe I have made a mistake with this firmware.

But I have also tried dload with ELS-LGRP6-OVS 11.0.0.232 and ELS-LGRP6-OVS 11.0.0.151, neither worked. These two ROMs are downloaded from firmfinder.

Can I use dload method with such firmware? Because I know the zip-file has a name of "update_full_base.zip", not "update_sd_base.zip". I manually changed the name and copied it into sd card.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Dload roms could be used for downgrade inside the same major EMUi version, not between major EMui versions.

So, try to use an older EMUI12 version dload first. After that continue as I wrote before.
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
I see. So you mean I should downgrade to the older EMUI 12 version with dload. Then use HiSuite with/without Proxy to downgrade to EMUI 11, right?

Can I use the ROM from firmfinder for dload method? Or is it just for HiSuite?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Dload roms are not the same as HiSuite roms
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Oh... So could you please tell me where I can download the dload ROMs?

Hi again. I have successfully flash dload FW from 12.0.0.350 (C432E3R3P4) to 12.0.0.218 (C432E3R5P5). But I still cannot downgrade to EMUI 11 using HiSuite either with or without Proxy. The same error (update failed) showed every time after downloading the ROM.

What can I do next...?
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Well, somehow I successfully downgraded my phone to EMUI 11 last night. I first updated OTA to 12.0.0.232, then use HiSuite 14.0.0.310_OVE to downgrade my phone to 11.0.0.232, without Proxy.

I don't know why it worked this time. But thanks alot anyway!

Now I will try to downgraded to EMUI 10.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Maybe to 11.0.0.260.
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
I cannot choose version when using HiSuite without Proxy, and there's no 11.0.0.260 (C432) on firmfinder.

So, reset to factory settings, get the files from description of the video.

Hi @badmania98, yeah, I'm trying to process the info you kindly sent me yesterday, but I don't understand this point.

2.Install GMS

3.Upgrade OTA

4. Install Push notification fix (PM me)

5. Set the PIN if it is needed.

6.Block EMUI Updates ( let me know if you want this)

what happens after point 3?

I mean, are the Google Mobile Services (GMS) broken - what kind of errors? - after the OTA update and so you need a new fix (point 4), is that correct?

Hi @badmania98

device p40 pro ELS-NX9, 11.0.0.223

For some time Ilham method was working for me, for a 3 weeks. but few days ago it stopped. Whatever I do, I have this play certification error. Now, after downgrading play market to 22.4.25-21 market works, I'm getting push, but whenever I install google maps - all crashing again and I'm getting play certified error. Is there any solution for this?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Use play services v. 21.21.16. Reinstall the fix (all procedure). Reinstall all Google apps.
[Huawei P40 Pro Guides, News, & Discussion] acipat:
Should I download it from Ilham file storage in gms_rule_xx_xx?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You can take it from apkmirror too. Should be 040408

I think Ilham file is (1)gms rule 3.0.

In certain conditions you can use any version. I use now 21.42.18. But is not necessary as soon as is not requested by an installed app.

v. 21.21.16 is 99,99% enough at this time.
[Huawei P40 Pro Guides, News, & Discussion] acipat:
Thank you, it really helped! I spent a few days trying to solve this. Very appreciate this! 21.42.18 - is the newest? how can it work? gms_rule3.5 is not working for me, and it is previous version

As I said the last version works in certain conditions. My phone is P40 Pro C432 EMUI 10.1.0.121 and it works. With my own settings.

LE: Pay attention to the configuration of Play Store and Play services apps. Auto-update in background should be avoided.
[Huawei P40 Pro Guides, News, & Discussion] acipat:
does it mean I should avoid running play store and block it from any data connection? because it has the ability to self-update and update play services.

View attachment 6033654

And when the phone restart to entering the downgrade process, it failed at the verfying phase.

No matter which ROM version I chose, from 10.1.0.137 to 10.1.0.176, it showed the same error and failed.

My phone is now running 11.0.0.211 (C432E3R5P4), the ROM I chose from firmfinder is:

P.S:

Maybe there are still people who can't downgrade.

I followed the following steps:

I downgraded from emui 12.0.0.350 to emui 12.0.0.218 using dload ( this version ) then I downgraded from 12.0.0.218 to emui 11.0.0.260 using HiSuite 14, then I downgraded to 11.0.0.230 through dload ( this version ), then from 11.0.0.230 to 10.1.0.131 ( here ) -

[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Hi! I finally downgraded my P40 Pro Plus (ELS-N39) to 10.1.0.137(C432E2R5P1). I used HiSuite (10.1.0.550_OVE) + HiSuite Proxy (V3.3.0) + Firm Finder V1. I lost fast charge, OTG and USB connection, as you mentioned.

Now the biggest problem is, I can only upgrade my phone through OTA to 10.1.0.144. Then no more update, no matter through OTA or HiSuite (wifi). And because I lost USB connection, I cannot update through HiSuite Proxy, which means I stucked at 10.1.0.144, and no fast charge, OTG and USB connection.😰 I didn't try dload because I don't want to lose GSM.

And I saw a method you mentioned here, but when I tried on HiSuite 11.0.0.550 (none OVE), Proxy always says patch failed. And I spend a whole day but still cannot find HiSuite 10.1.1.500 (none OVE).

So could you please send me the install file of this version? Or are there other ways to update to the latest version of EMUI 11? Thank you very much in advance!!
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Hi, I downgraded my P40 Pro Plus almost the same as you did. It's a long hard week.

Have you also lost fast charge, OTG and USB connection? And can you update to the latest version of EMUI 11 through OTA? Because I stucked at 10.1.0.144. Like I described above.
[Huawei P40 Pro Guides, News, & Discussion] Maryan40k:
I don't know if fast charging was disabled when I had emui 10.1.

After installing GMS, I immediately received an OTA update to emui 11 and 12. Try with HiSuite 14 or update from erecovery (do not try with dload because it is not good between major versions)
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:

[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Both 13.0.0.310 and 14.0.0.310 don't work. Proxy says "Patch failed". I think it's HiSuite Proxy doesn't support HiSuite 13 and 14. And also HiSuite 11.0.0.510 non OVE. Tha't all of the versions I can find.

So I would like to ask you if you could share HiSuite 10.1.1.500 (or any non OVE version that works with proxy) to me? Thanks a lot!!
[Huawei P40 Pro Guides, News, & Discussion] Crypto-1:
Hi all. I have a similar problem. Huawei P40 Pro C10 R4 from 12 emui was downgraded to 11 via HiSuite, after 11 Emui via Hisuite+Proxy downgraded to 10.1.0.131, after the phone did not see the new firmware, I tried HiSuite 10, 11, 13, 14, tried using VPN on PC, tried to update from my phone, there is no new firmware, notification that 10.1.0.131 is the latest. It seems that Huawei no longer supports updates from 10 to 11 emui. If you upgrade the firmware to 10.1.0.176 through hisuite+proxy, then Google remains, if you upgrade it to 11.0.0.152 through hisuite+proxy, then the system is installed clean without Google. *(I am writing via Google Translator)

Do you have SIM card in the phone? If not, insert it and search for OTA.
[Huawei P40 Pro Guides, News, & Discussion] Montgomar:
Thanks for the hint. But I couldn't get OTA update either with or without SIM card.

I used HiSuite (10.1.0.550 non OVE, connected with wifi) + HiSuite Proxy (V3.3.0) + Firm Finder V1 to updated to 11.0.0.151. Then I got update through OTA (without SIM card) to 11.0.0.211. After OTA update, fast charge, OTG and USB connection came back. Then I OTA updated to 11.0.0.232, which I think is the latest version of EMUI 11, because after that I got OTA push to EMUI12. But I didn't update.

Thank you veeeeeeeeeeery much for all your help!

Hi, I used HiSuite (10.1.0.550 non OVE, connected with wifi) + HiSuite Proxy (V3.3.0) + Firm Finder V1 to update to 11.0.0.151, GMS remained. I don't know why your update cleaned your system.

I tried many combinations because when I used HiSuite Proxy V2.4.0.0, it will pop up an error message like I posted here. And strangely, same error message will pop up when I upgrade from 10.1.0.137 to any other version of EMUI 10. So I directly update to 11.

Hi,

I did managed to get further.

I think I made it worse, by not removing work profile (sometimes I activated to sync with company, even I cannot get apps).

Since yesterday, Play store cannot connect, it shows df-dferh-01 error.

Apart from that it seems everything works (google stuff, phone in general).

I downloaded 'device id' app and it shows no gsf Id.

Are there some steps to try making store work again? I tried delete data, force stop, restart, but did not help. (Gsf is still disabled)

It was quite good to have working store, although Aurora works but it's not the same, I'm thinking, trying to rollback and start over, if nothing else to try.

Any tips, if someone had same issue?
