What region is it?

OTG + dload firmware is not used to downgrade between major EMUI versions (11 to 10, 12 to 11)

Harmony TP cable is used when you lost USB connection from computer to phone. Also on first page you can find another cable for this problem , if your computes has a USB-C port.

my mobile is not connecting to pc after downgrade and usb otg is also not detected using usb c to c another mobile is connected pc make sound but not detect device
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
a. USB-C to USB-C cable (if you have USB-C port on PC) it is used to connect the phone to computer and use HiSuite/Proxy.

Not every USB-C cable is good. Read on first page about a good one tested by me.

b. OTG + flash drive is working in this condition, but you have to try other flash drives if it is not working.

i was told to read post 2 for downgrade procedure.

then it bring me to the below post

[Christmas gift: How to downgrade from the last version of EMUI11

(ex: P40 Pro C432 EMUI11.0.0.260)]

can anyone help me in this regard?
[Huawei P40 Pro Guides, News, & Discussion] aingerunn:
I need help. I do everything, according to Post 2. I don't know what I'm doing wrong.

I've gotten downgrades to 11.0.0.260. But I can't downgrade to 10.1.0.121. I tried a 10.1.0.176 and it gives the same error.

Download and install successfully. In Mobile when updating, it gives an error at 4%.

I have tried Recovery and Dload. I can not. Thanks for your help.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
The phone could start on EMUi? Also on message no.2 it is another step, to downgrade from 11.0.0.260 to 11.0.0.230 with dload firmware (point 0 (zero) b)). From 11.0.0.230 you can downgrade to 10.1.0.121 with proxy ( also presented on message no 2, point 3).
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You have to start HiSuite (the apk version from that 11.0.0.610 should be installed ) on Phone too.

Hi bro.. I have Huawei P30 ELE-L29 (C185...), Kirin 980, and EMUI 12 installed.. Android 10 based.. I want to unlock my bootloader to install GSI ROM with android 13.. But it needs unlocked bootloader to install it via fastboot and i need to be on EMUI 9.1 to be able to unlock it as i read it before.. Hisuite can only downgrade my device to EMUI 11.. How can I make it work bro? EMUI is garbage and will stuck on android 10 forever.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
As I know bootloader unlock can be made under EMUI8.0. If it is done on EMUI8 it remains unlocked under EMUI9 but it disappears under EMUI10. It reappears under EMUI9 if you downgrade from EMUI10. I have seen somewhere that if you upgraded to EMUI12, it is a no go to re-unlocked it.

My opinion is to use it as it is. Trying to downgrade now will be risky as I mentioned on message no. 2 of this thread, yesterday.

Good day,

I'm having an issue with Whatsapp.

I noticed that any message or vocal I send to any wapp group will not been send and it keeps with the "clock" icon.

Do you have any idea about that? Direct conversation works fine and notifications too (maybe sometimes they came a bit late).

ALso can i downgrade with the dload method with a usb to usb-c pen drive or do i need otg cable? because when trying before to downgrade throgh hisuite proxy it wouldnt work
[Huawei P40 Pro Guides, News, & Discussion] dimutris:
Currently sitting on C432E5R6P2
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
DLOAD is used INSIDE of the same major EMUI version ( ex: from 12.0.0.xxx to 12.0.0.yyy), not from a higher version to a lower version (Ex: from 12.0.0.xxx to 10.0.0.xxx)
[Huawei P40 Pro Guides, News, & Discussion] dimutris:
Understood what i mean is first downgrade to 10 399 and then use dload to be on the proper version in 10
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
It is possible to not have USB connection after first downgrade. You can try.
[Huawei P40 Pro Guides, News, & Discussion] dimutris:
So as I understand it version should be 136 right and cust and preload should be 1 or 2? If I chose a different R because i cant find mine will there be an issue?
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You asked me also on PM. You have the detailed answer there.

In my opinion R version is not 100% important.

[Huawei P40 Pro Guides, News, & Discussion] leopesto:
It looks like now some minor groups (family, 5 persons) are working, but not the biggest ones.

I'm thinking it has something to do with contacts sync.

I must say that my P40 Googlefied is working great, notifications works (maybe gmail a bit slow) and no Google Play Services notification anymore.

Tried to force stop, uninstall and install both contact sync app 5 and 10 without any result, contacts sync always give me error and stay updated last time when Googlefied (2 weeks ago).

I've no idea what to do more, should I try to reinstall GMS or something?

I'm on ANA-NX9 11.0.0.246

GPServices 20.09.14

GPStore 35.9.11-29

GSF v10

GAM 6.0.1

Contacts Sync 4.2.2-721232
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
What do you mean by reinstalling GMS? If you want to downgrade again....se my message no2 beginning. It is hard to do that now.

In my opinion you could have some incompatibilities between Google apps. It could work or not, after new GSM install.
[Huawei P40 Pro Guides, News, & Discussion] leopesto:
I was thinking of delete google services and re-googlefier or trying one of V1-V4 in post #4...

I don't want to downgrade at all, I don't want to backup all again and then factory reset...

Maybe I should update to EMUI 12 and see if it's just related to my EMUI version?
[Huawei P40 Pro Guides, News, & Discussion] Thrilling:
Hello,

I am also interested in your answer.

My phone desperately wants to update GPServices to 23.17.xx.

Usually, when this happens, I delete all the Google services data. Then I uninstall and reinstall version 21.24.57.

And when version 23.17.xx came back, I started again.

This solution worked for a few days.

But since yesterday, the update to 23.17.xx is immediate...

Thanks for your help!

Hi,

[Huawei P40 Pro Guides, News, & Discussion] Lowkey_Xboy:
Hi, I have a ELS-NX9 P40 Pro (region c636) with EMUI12. I have followed very carefully by the steps and guide provided in this thread and successfully downgraded to 11.0.0.249. However, I am not able to further downgrade to EMUI 10 regardless of any version available in HuaweiFirmFinder. The method I used to downgrade from EMUI11 to EMUI 10 is the one in thread #106.

I do not get any error message in HiSuite, but I do get alert message in HiSuiteProxy everytime after download phase and at the beginning of install phase(see attached). Nonetheless, the installation will successfully get through. When phone reboots, it will start installing progress and stop at 5% and says 'Software install failed'(see attached).

I hope someone can shed some light on this. Much aprreciated.

Current info:

Base Software Version: ELS-LGRP4-OVS 11.0.0.249

Cust Software Version: ELS-N29-CUST 11.0.0.3(C636)

Preload Software Version: ELS-N29-PRELOAD 11.0.0.3(C636R4)

Downgrade version I have tried but unsuccessful

Base Software Version: ELS-LGRP4-OVS 10.1.0.109 until 10.1.0.182

Cust Software Version: ELS-N29-CUST 10.1.0.7(C636)

Preload Software Version: ELS-N29-PRELOAD 10.1.0.1(C636R4)
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
You better upgrade back to 12 and downgrade via HiSUite to another 11.0.0. between 200-230. After that continue with those steps. From 249 you cannot downgrade. Even in this case you can get errors, but we will see.

The best solution for you is to:

1. Write on NM card a 10.1 desired dload firmware (134???)

2. From EMUI12 use v2 (downgrade tab) and downgrade to an available EMUi10.1

3. From that EMUI10.1 downgrade with NM card+dload firmware to 10.1.0.134

I have the same problem on my P40 PRO C432, from EMUI 12 I managed to go down to EMUI 11 230 like you, following the guide of badmania98 and mattwhite7102, which are almost identical, but nothing, it gives me the same error you showed right after the download reaches 100 on Hisuite.
[Huawei P40 Pro Guides, News, & Discussion] badmania98:
P40 Pro C432:

Last time I used NM card with dload firmware 10.1.0.121 on it, copied when I had USB connection (EMUI11.0.0.2xx to EMUI12).

I downgraded first with HiSuite Proxy to 10.1.0.176 from EMUI12 then with dload on NM card to 10.1.0.121.

If you dont have a NM card you can try to use dload firmware with USB OTG+pen drive. It could work.

Hi, firstly thank you for your tutorial. I followed it and it worked fine on my latest p40 pro, installed all gms and upgraded to latest emui and it was all still working fine.

Then I did phone clone from my other p40 pro running gms (smashed screen)

And now I have a device not play protect certified error 🙄

Is there a quick fix without undoing the whole process? I can only assume I should have done phone clone before updating to latest emui perhaps?

If you have any suggestions I would appreciate it 😊

** EDIT **

Badmania98 got in touch with me and was a great help at solving this issue and others, now errors are fixed and I'm getting all notifications that I wasn't getting before.

Hi badmania98.

Here is my situation, can you please tell me if it's worth trying to install GMS?

I have a Huawei P40 Pro. When I received it, I installed EMUI 10, installed GMS and everything worked fine.

Then at some point, I activated Dual Whatsapp accounts and for some reason unknown to me, GMS did not work anymore.

I reset the phone to factory settings, back to EMUI 11 and started the whole process over again but never got it working. After spending days trying many different methods, I gave up and installed GBox.

GBox has many annoying bugs, nothing works fully properly.

So, here I am, willing to try again. The current configuration is:
