Never. Huawei made changes on the firmware to dont downgrade anymore to 10.1 and so. If the downgrade will be available again in HiSuite, I think it would be till this version (19x), not bellow.

Sorry, the only solution for me was the update via OTA, after some updates the USB comes back normal

i´ve downgrade my P40 Pro C432 from 11.0.0.196 to 10.1.0.176 via the last HisuiteProxy and Hisuite 10.1.0.550 with the right Preload and Cust. The USB connection works without problems.
After that you could downgrade to 121 or 131 via Dload Method

I have install the Hisuite 10.1.0.550 on my PC. Then i connect the P40 and Hisuite. Usualy he installed an version of the Hisuite App on the Phone. If the connention is ok, then you couldt close the Hisuite on the PC and on the P40. After that you start the Hisuite Proxy and look on the firmfinder.ml site for the correct base, cust and preload Firmware and press on add Rom. After that, press setup on the Hisuite Proxy and an log console is opening. After he is finishing, in the Console writes, that you could proceed with the installation. Then open the Hisuite on you pc, connect it with you P40 an press on the update button. In this time in the debug console of the Hisuite Proxy must you seen some links for the Firmware.
Sometimes you need activate the USB Debugging on the phone. Usually i reset the phone before the downgrade and set up it only with my wifi settings.

Why don't you downgrade to 11.0.0.196 to 10.1.0.121 or 131 but have to downgrade to 10.1.0.176 and then use dload to downgrade, instead of directly downgrade on Hisuite

Because you lost the USB connectionand fastcharge when you directly downgrade to .131 from EMUI 11.
When you downgade from 11.0.0.193 to 10.1.0.176 with Hisuite and Hisuite Proxy the USB Connection will remains.

How do you know if you downgrade from 11.0.0.193 to 10.1.0.176, the USB will still work or is it a coincidence when you choose the downgrade version?

Because i have done this kind of downgrade a couple of times and the USB Connection works after it.
The downgrade was official avalible till 11.0.0.176 Firmware via Hisuite. At this time Hisuite makes an downgrade to the 10.1.0.176 and then you could downgrade to .121 or .131 via Dload or Hisuite Proxy. That is the reason, why i tested it and the result was an working USB Connection.

I trie'd with Hisuite but it said that my software is current.

Which firmware should I install from FF? Latest avaible in FF or 10.1.0.270?
Search about your phone model, LIO-LGRP2 or LIO-LGRP4 (I don't know what model you have); once you know the model, search latest update, FullOTA (almost 4-5Gb).
Thanks. I will try this.
Be sure you choose the corect firmware, for exactly your phone model.
Right model, latest update, FullOTA.
Follow exactly the steps you need to do, from the presentation of HiSuite proxy method.

Downgrade from 11.0.0.151

I am using a mate 30 pro now with 11.0.0.151. When i try to do a downgrade with hisuite proxy with hisuite 11 i have always error, so i have understood that i need to use hisuite 10 because hisuite proxy is not compatible with emui 11. But now i have a new problem: the apk of hisuite 10 is not fully compatible with emui 11 so i can not connect the phone with hisuite on pc.
So what is the solution in my case to downgrade? Thanks. Please help.
Having the same kind of problem, I'm on 11.0.0.153

I can't downgrade because hisuite proxy has no internet conection

I tried to downgrade and the only hisuite that works for me is the last one (version 11).
When I use hisuite proxy and start hisuite I click in "updates" and I've got the message "NO INTERNET CONECTION".
If I tried without hisuite proxy Hisuite works but with the lastest firmware and I can't downgrade.
How can I solve this issue?
Thank you
Sounds like windows firewall might be blocking hisuite proxy. Check the firewall to see if you have any pending entries.
I have the windows firewall disabled
you need version 10, try another PC
I downgraded with the oficial Hisuite (to another version) and from this version I can downgrade to de 1.31

P40 Pro Wrong Firmware

Hello people. I have downgrade my phone with hisuite proxy, from 11 to 10.
I didnt look good, and instead of n29 i have installed n39. on my phone is writen nx9 model so i was belived that is ok to install n39.
I have installed that version, install GMS, was working ok. I didnt look at charge, but fast charge and pc connect not working anymore.
I try to connect the phone to pc, to reinstall the right version. but no chance, i have try eRecovery, not working also,
The only thing i can access tru update otg.
I have download dload n29 emui 11, but when i try to install is not working. what can i do now to come back to normal.
to install n39 emui 11?
Many guys tried to change to nx9 after that from this point but no success. It wasn't tryed to update to the last Emui11 of n39, maybe the connection to the computers will be activated again. After that use HiSuite proxy to change to nx9.
so, should i wait? and use like this with no fast charge? or try to update emui 11 from n39
You have no alternative. If I were you I would try to update.
i cannot brick the phone?

Downgrade Emui 11 to Emui 10

Hi,
since 2 Days i try do downgrade my Huawei p40 pro ELS-NX9.
After reading many Threads i have now the Build number 11.0.0.180 which could be downgrade.
Now i try to flash 10.1.0.178 and 10.1.0.131 but nothing works.
Every Tutorial to use Proxy failed because i can not install the HiSuite Version they want.
Can anybody help me?
Download, extract and install this first and try to install HiSuite after that.
See my thread (in my signature) for many tutorials.
You have to upgrade (OTA) to 11.0.0.230 maximum to have USB connection and use HiSuite Proxy.
At first!
THANK YOU for the fast answer. It fixed my Problem.
Now i have Build 10.1.0.176 after OTA 10.1.0.154 to fix usb adb.
I can not flash otg the version 10.1.0.121 an HiSuite doesn´t except my P40
I wanna flash a lower Version to install google services.
But which firmware should i use und how install it?
ELS-LGRP4-OVS 10.0.0.176
ELS-29_CUST 10.1.0.8(C432)
ELS-N29_Preload 10.1.0.1(C432R6)
Should i look after a Firmware withe exact the same details like my?
R6 in Preload have to be the same?
I try:
Huawei P40 Pro ELS-NX9 ELS-N29 hw eu HLRCF Elsa-N29D 10.1.0.114(C432E8R5P2) Firmware EMUI10.1.0 05016PSR [androidhost.ru](1) = doesn´t work
Elsa-N29D 10.1.0.131(C432E8R6P1)_Firmware_EMUI10.1.0_05016PSR = doesn´t work
Thanks before
I already told you what to do.
So i can not flash the Version 10.1.0.131 to install Google Services?
OTA i update to 11.0.0.230 and get my usb connection and fastboot back. Then downgrade with proxy to 10.1.0.154 = works
But how i come from this Version to 10.1.0.131 to install Google.
With 10.....154 and 10.....176 odb isnt working.
Ok ifound the issue! Thx for helping
I got it to downgrade too. Thanks!
Hello, I need help. I have a Huawei Mate Xs and I'm currently on EMUI 12.0.0.290. A month ago, I downgraded to EMUI 11 and then to EMUI 10. Now, after a month, when I try the same downgrade (absolutely the same version of the system, using the same method), the lowest I can go is EMUI 11.0.0.168. When I try to roll back to EMUI 10, any version, the device goes into bootloop and nothing helps (delete cache memory, factory reset). The only way is System Recovery via HiSuite Proxy on EMUI 11 and that's it. Has anyone else had a similar problem and is there a chance that Huawei will put some sort of ban on it with the 12.0.0.290 update
