https://youtu.be/EydJcYIlI8o

Thanks you, I will try this method right now.

It's work with this method , i was able to downgrade from 154 to 131 thanks a lot !

nice

This metod is not working for me. Any news is this locked by Huawei ?

I can confirm that 154 seems to be resistant to the proxy intercept.

I cannot put links here, but I will try to help.
1º - Search on Youtbe for EloYGomeZTv is in Spanish try subtitles in your language,
2º - Search the video " BAJAR VERSION FIRMWARE HUAWEI - SOLUCION AL ERROR DE LZPLAY (G Address) "
3º - I know that to indicate another problem but, it gives a solution for the downgrade and for me this method worked,
4º - He have all the links for the programs you need to downgrad from 10.1.0.154 to 10.1.0.131,
5º - You have to do exactly the steps is doing,
6º - You have to use HISUITE PROXY to.

Hi, can anyone explain to me why the Proxy app won't run at all. I tryed installing newest and some older Hisuite. Tryed run as admin. Or not to run HiSuite when it installs. But whenever I try to run HiSuite Proxy it just shows on mouse cursor for few sec that it is loading,but no window shows up.
Anyone knows a solution ?

Yes sir. I downgraded, installed GMS, then updated to the latest version and GMS still works.

the method doesn't work for me, tried the German and the Spanish video, when I press Update HiSuite give the error that there is no Internet connection?

I'm trying this version to downgrade from Emui 11 beta but when I do it tells me I'm on the latest version. I've used it before to rollback to .131 to install GMS with no problems. Has anyone used this method to rollback from Beta 11?

Hi, have you made sure you used the HiSuite 10.1.0.550 version? It won't work if you are using a higher version

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

Downgrade from 11 to 10 for install GMS (HELP)

Hello guys. I have a mate 30 pro 4g EU version. LIO-L29
EMUI version - 11.0.0.188
I wanna downgrade to 10. Because i wanna install GMS. I have succes downgrade last 2 week on p40 pro.
Now i try first to downgrade first from Hisuite. I have install Hisuite_10.1.0.550, but i dont have the button switch to other version.
if i try to HiSuite Proxy, i recive error:
[15:48:06]: Connection To HISuite Proxy Failed....
[15:48:07]: Check If Your Firewall Is Blocking HISuite's Proxy Server
i have add the app to the firewall, i have stopped the firewall...same
Please help me to figure out.

Hey man. I'm in the same boat. Unfortunately, I don't think we are able to downgrade to a lower version. So, we are stuck without Google. The only negative of not having GMS is the delay or no notifications coming in at all. Hopefully apps will be updated to work well with HUAWEI notification eco system.

Hey bro. I have succed to make it

ช่วยบอกวิธีทำหน่อย thank you

Hey, can you share with us how you downgraded from 11.0.0.188. Thank you.

With hisuite proxy

Thanks. Which firmware version you downgraded to?

Well, after multiple attempts using different firmware versions, the update fails after it has reached the 100% download. Have no clue what else to do. Firewalls are off, antivirus off. Anybody?

I followed this guide: Make sure those selections matches your phones need (region, etc..). If they don't match,..you know what might happen.
Complete Guide
Modifying HiSuite and manipulating it's connection data to install Roms before they officially get released. - ProfessorJTJ/HISuite-Proxy
github.com
BUT like I mentioned at a different thread. If downgrading to 10, Googlefier Wouldn't work. Also, I had lost USB connection and fast/super charge. But I think downgrading to a lower 11 should be ok. But I don't know. If you loose that, just upgrade again.

@robjbw thanks for answering. It will help everyone.

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.

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
