Hello, I have the same model of P40 with you, and I can't find a dload firmware anywhere on the internet. Did you have luck finding one and fix your phone?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
More details will be good. What firmware do you have now installed? What firmware would you go to?
[Huawei P40 Pro Guides, News, & Discussion] astro_boy2005:
Good Day,

Kiwi (From New Zealand here) I just bought a second hand Huawei P40 Pro phone for my teenage son.

I have been following a lot of thread here and I have a similar problem. Hoping someone can share or help.

Model: ELS-NX9

Build 10.1.0.182 (C636E7R4P1)

EMUI 10.1.0

1. HiSuite Software not detecting P40 Pro (Have tried all previous version and latest version)

2. Cannot do software upgrade EMUI Version OTA always showing "software is up to date" Current version 10.1.0.182

Please see attached photos, please help me downgrade to version 10.1.0.131 to install Google Play.

Would appreciate your step by step guidance.

Merry Christmas and Happy New Year!
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Hi!

For C636 you need 10.1.0.134 C636 ( not 10.1.0.131 C432). I have it.

You also need a NM card to be sure that downgrade could be done. But you can try (if you already have them) with an USB-C OTG and memory stick/card reader +memory card.
[Huawei P40 Pro Guides, News, & Discussion] astro_boy2005:
Hi badmania98,

First a BIG thank you for your quick reply. I would really appreciate if you can tell me what I need to do next after

Thank you for the very informative answer.

I am trying to find the downloaded archive above as mentioned but no luck.

Can you please re-upload the Firmware version that I need which is C636 (FW Version 10.1.0.134 C636)

Thank you

Good Evening from New Zealand!

Thank you very much for your reply. Very happy I have downgraded the P40 Pro now.

Here are some points I encountered after the downgrade:

1. I have successfully downgraded the version to 10.1.0.134 by watching the video you have shared.

2. Error came "This Device Isn't Play Protect Certified" as soon as I finished all of the video from step 1.

3. I read and I downloaded the files from ICTFix.net and followed all the instructions on how to fix device isn't play protect certified.

4. Everything works fine but after downloading another app (Covid Tracer App for NZ) it ask me to "update google play services". If I don't update then the Covid Tracer App will not work. So I went to step 5 ---->

5. I updated the "google play services" it went back to - --> "This Device Isn't Play Protect Certified".

Is there anything you might suggest what went wrong? Is there anyway how to fix this?

Or only go with the hard solution which is to repeat step 1 again?

Your favorable response will be highly appreciated.

Best Regards.

Regards.

You did good. It is not necessary to reconfigure. See your PM.

After downgrading and installing Google services I made the first update that brought me here, now I'm stuck. I tried them all also through the firmware found here but I always give the error. Do you have any solutions? I can't install emui 11 or go back to an older version of emui 10
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Usually that is happened when you downgrade to 10.1.0.131.

a. See my upgrade procedures described here:

b. try to use USB OTG+ memory stick (50%) or NM card (100%) to downgrade to 10.1.0.121 and repeat the procedure (install GMS etc)
[Huawei P40 Pro Guides, News, & Discussion] NicolaDello16:
where do i find the 10.0.1.121? I have so far used a stick with usb c connection already included because it is the only working method I have at the moment since it is not recognized by the pc
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I used this:

Google Drive - Virus scan warning

drive.google.com
[Huawei P40 Pro Guides, News, & Discussion] NicolaDello16:
Once installed, do I repeat the procedure for google services and once finished I try to put emui 11 directly?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You install GMS and after that use OTA or erecovery to upgrade. Do not upgrade to a higher version that 11.0.0.230. You will not able to downgrade for ever. Read my thread ( see my signature)
[Huawei P40 Pro Guides, News, & Discussion] NicolaDello16:
Out of curiosity, did this happen to me because I started from a wrong emui version? or when I try again can the same thing happen to me when I try to update? Because in the last attempt after making the first update via erecovery then it crashed as you saw earlier
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I have no explanation. I have just... experience and a good memory. That is how things work now.
[Huawei P40 Pro Guides, News, & Discussion] astro_boy2005:
After our conversation last night today I made another experimental on my Huawei P40-Pro

Re-install FW again to version 10.1.0.134

Download the ictfix file "GSM Fix" at the SAME TIME Download also the "Fix GSM Play Protect Certified".

Turn off wifi and continue GSM Fix and GSM Play Protect Certified WITHOUT installing any apps.

Reboot and Turn on Wifi. Refresh and Check Google Play store and test by downloading apps.

So far I have not encountered any errors Play Store Ver 28.3.16-21

Note:

I have not installed Gmail apps as I have noticed when I installed this during FW downgrade the "GSM Play Protect Certified" error has never been resolved. What I did was to use another stock app from Huawei which is "mail" and sign on my gmail.

Question:

Is it now safe to software update to version10.1.0.182 ??

Until when shall we software update and when to stop ??

Thanks Dan :)
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You can go up till you get back the connection to computer through USB cable. Then is better to block the upgrades.
[Huawei P40 Pro Guides, News, & Discussion] NicolaDello16:
Thank you so much badmania! All solved with Play store and emui version 11.0.0.230 installed
[Huawei P40 Pro Guides, News, & Discussion] astro_boy2005:

Just asking if Gmail apps works without any problem with 11.0.0.230?

* Factory reset more times...

If someone can point me in the right direction that would be very much appreciated, thanks in advance .
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
In your case downgrade (dload method) to 10.1.0.121 (firmware is here) using NM card, then you can make upgrades (after you install GMS) with OTA or ERecovery (wifi).

Your phone is C432?
[Huawei P40 Pro Guides, News, & Discussion] onderduiker:
Thank you for the very fast reply. I am gonna try that. Yes C432.

Mmm, I see that I allready tried that firmware. Software failed, incompatible.

I will try it again.

Notice it is E8 not E7 ??
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Doesn't matter. Try again.
[Huawei P40 Pro Guides, News, & Discussion] onderduiker:

Hi

Can Someone assist me in this, I have tried all the solutions and all the files shared but nothing is working with me, When I try @badmania98 files it gets stuck on verifying update.

Is there a special file for this phone ?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
What do you want to do? Do you have NM card or OTG or connection to computer through USB cable? Your phone is C185. What files have you tried from me with C185?
[Huawei P40 Pro Guides, News, & Discussion] hashem1992:
Hi

I’m sorry but I’m not professional in this, I use USB with adapter and the phone is identifying them but the computer connection is not working, I used the files you uploaded at the beginning but it’s not working for me I guess it’s a different version
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
It is different for sure. What do you intend to do? Downgrade? Install GMS?
[Huawei P40 Pro Guides, News, & Discussion] hashem1992:
I intended to install GSM services but apparently I ****ed it up, if you can help me I would really appreciate it.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I think is better to read my first 7 messages on my thread. Here you have all you need.

Ask me on that thread if you need more details.

You will need this firmware to downgrade with DLOAD method.
[Huawei P40 Pro Guides, News, & Discussion] hashem1992:
I tried the firmware and the attached photo is what came up to me
[Huawei P40 Pro Guides, News, & Discussion] onderduiker:
Tried, no luck, message like above. I will try usb c to usb c tomorrow.
[Huawei P40 Pro Guides, News, & Discussion] onderduiker:
usb c to usb c not working either.

I guess I am out of options :unsure:
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I don't know what are you doing there. I don't think all goes wrong.
[Huawei P40 Pro Guides, News, & Discussion] onderduiker:
Not my first time with custom firmwares.

But it doesn't work, and I don't know why. Followed every thing a few times.

It went wrong by changing to 10.1.0.176.

After that no usb only charging.

Always the same message,

Software install failed! Incompatibility with current version

Please download the correct update package
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
How did you downgrade? What method? What firmware was before downgrade?
[Huawei P40 Pro Guides, News, & Discussion] onderduiker:
I don't know excactly witch firmware, but I used HiSuite.

I tried to times. First time it went ok, but no usb. Then auto update two times to the latest.

After that I I guess it was the current version. Followed tutorial exactly.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
you didnt. Because you used a wrong CUST. See your PM.
[Huawei P40 Pro Guides, News, & Discussion] gluck1:
I understand that this is probobably a wrong thread, but I'll try

Is it possible to find P40 firmware for c10 region (Russia) with version downgradeable with HiSuite? All versions I found are C432 only
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
Tell me the all story. What Firmware do you have (post a screenshot of About Phone) and what do you want to do?
[Huawei P40 Pro Guides, News, & Discussion] gluck1:
I'd like to downgrade the firmware to theversion where google services can be installed. Unfortunately as i understand my version can't be downgraded directly using hiSuite proxy any more, and a downgrade using dload is required. So I'm looking for a suitable firmware for that for my region.

Meanwhile i found this firmware:

Huawei P40 ANA-NX9 ANA-N29 hw ru Anna-N29CB 10.1.0.168(C10E6R6P1patch02) Firmware EMUI10.1.0 05016PWN.

Can i directly downgrade to emui10 from my firmware using this file?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
There are few options, but some of them are risky or very risky. You have to get 10.1.0.121 to install GMS at the end.

V1. From 11.0.0.241 to 10.1.0.121 using HiSuite Proxy.

V2. From 11.0.0.241 to a lower version with original and newest version of HiSuite (not proxy), if the downgrade is available. After that continue with HiSuite Proxy to 10.1.0.121.

V3. (Risky) From 11.0.0.241 to 10.1.0.178 (from here, not for free) or 10.1.0.168 using DLOAD method. Will be no FastCharge and USB-cable transfer data between computer and phone. Then Upgrade (if available, with OTA or eRecovery+WiFi) several times to the first 11.0.0.2xx firmware that will provide you back the USB connection to computer. After that continue with HiSuite Proxy to 10.1.0.121.

V4. (Very Risky) Method B described here. Firmware in Note 1.
[Huawei P40 Pro Guides, News, & Discussion] hashem1992:
Thanks @badmania98 for your assistance 🙏 , For the C185 I bought a type C flash drive, it didn’t update through *#*#2846579#*#* as the phone couldn’t identify the drive but it did work through the pressing power button + volume up after turning the phone off , I don’t know why but eventually it worked.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
All is OK now?
[Huawei P40 Pro Guides, News, & Discussion] hashem1992:
Yea , Google play services are working and the phone have the latest update as well.
[Huawei P40 Pro Guides, News, & Discussion] gluck1:
V1 - HiSuite proxy site published the following warning:

- ALERT : Downgrading from Latest EMUI 11 disables your phone's Fast Charging, Fastboot, USB Connection and TestPoint.

- The only way to fix it is updating through OTA, E-Recovery or Dload by memory card to latest EMUI 11.

So I'm not sure this is a good way

V2 - unfortunately HiSuite (not proxy) does not allow to downgrade from the version I have so I'was looking for an EMUI11 dload firmware with older version to rollback and use HiSuite for firther downgrades

V3 I thought dload firmware is downgrading all components so dload firmware can be used to move from any to any version, isn't it?

V4 looks like it will be the last resort
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
I would try in this order V1-V4. If you know better...go ahead.
[Huawei P40 Pro Guides, News, & Discussion] celltellpb:
The fact that the P40 PRO, no longer recognizes the usb connection after downgrade, has nothing to do with the cable or the device's connector.

I downgraded my device from EMUI 11 to EMUI 10, and it immediately stopped recognizing it.

I changed the cable, I changed the computer and it still didn't solve.

I ended up reinstalling the updates available via and wifi, and when I reinstalled 11.0.0.202, the device recognized the USB port again.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:

It is hard to fix. But I need the full story. What EMUI version was before, what is now, what you used etc. A NM card is needed. I dont have a 100% solution, beacause is no EMUI11 C636 dload firmware available. I dont know if it can read now from OTG.
[Huawei P40 Pro Guides, News, & Discussion] johnnyyh:
Previously was in EMUI 11 with full gapps working. Only notification problem. One day I want to try to fix the notification issue and I downgraded to 10.1.0.134 and reinstall google. At that time gapps installation was not successful. The I try to downgrade lower. I accidentically put ELS-N39 10.1.0.132 OVS , 10.1.0.1 R5 preload and 10.1.0.8 cust on hisuite proxy to flash.

a. download 11.0.0.230 from here.

-extract dload folder

b. download 11.0.0.202 from here.

-extract dload folder

c. create another dload folder on the computer

- copy on it the update_sd_base.zip from 230

- copy on it the folder ELS-N29_hw_eu from 202

d. copy this dload folder (from point c) to the NM card

Hello,

I have a usb problem. After the downgrade, I can't connect to hisuite via usb. Only when I update 11.202 emui, the error is fixed. I tried both versions for p40 pro.

ELS-LGRP4-OVS 10.1.0.121 + 10.1.0.8(C432) + / ELS-N29-PRELOAD 10.1.0.1(C432R4)

How to fix usb problem without emui update? (for 11...202)
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
To have the big picture you can read no 7 here.

Just to use USB connection you can try to use:

a. HarmonyTP cable

or

b. UGREEN, US355, USB-C To USB-C, 3.1, Gen.2, PD, 5A, 100W, 4K, 10 Gbps cable

”Our new mate ......... provided us 2 images which prove that transfer files between Computer and phone is available on the downgraded firmware (10.1.x.x) when you use a certainn USB-c to USB-c cable. In this case a UGREEN, US355, USB-C To USB-C, 3.1, Gen.2, PD, 5A, 100W, 4K, 10 Gbps cable has been used. In the same time, using the original USB cable or other ordinar USB-c to USB-C cable have not activated the file transfer.”
[Huawei P40 Pro Guides, News, & Discussion] zemla387:
Thank you for your answer.

Why do you think usb and fast charge don't work when you downgrade like this? Did you have this problem, or did I not make it?

121 or 131 downgrade As far as I can tell, usb and Fast charge won't work without 100w cable or emui update?

Hello @badmania98,

Thanks a lot for sharing this and for all your efforts on the subject.

I would like to try this procedure, but I cannot download the firmwares 180 and 202.

The link is asking for a password... Did I miss something ?

I am very new here, sorry if my question is silly.

Thanks again

You are right. I will provide the password for a short period of time if you convince me that you are in the situation and have the same error on the same phone as described. Many guys didn't understand the thread and wrote those firmwares on different phones or regions.
