Hi, I have been trying to find a way to downgrade my phone from EMUI12 12.0.0.218 to EMUI11 11.0.0.260, but I am unable to find the EMUI11 11.0.0.260 version. I also cannot find it using step 0 on https://forum.xda-developers.com/t/...ews-discussion-support.4346741/#post-85769677 as I have tried to downgrade to 11.0.0.249 beforehand. Is there anything I can do to downgrade my phone? My phone is Huawei P40 Pro ELS-N29 C636R4
I have searched for most of the other post too but cannot seem to find a way to downgrade this to 11.0.0.260. Downgrading to other versions just shows “Software install failed” and I can only press restart. From what I have seen here(https://forum.xda-developers.com/t/...cussion-support.4346741/page-19#post-86174321), only downgrading to 11.0.0.260 can be done.
Any help is much appreciated, thank you
P.S. I am using HiSuite 11.0.0.590, not sure if this is the right version

I also have same issue.

I think is not available for all regions. What Cxxx region are your phones?

Update issues after Downgrade

Hi all, I have downgraded my p40 pro to 131 to get google apps working. Then tried auto updates and it tells me that there is an update but same version 131, updated to 131 using auto update but it still keeps telling me that I'm on 131 and same version of update available. Connected to PC and use Hisuite and same story, tells me 131 update available (which I already have) and nothing else. Was able to update to 154 using proxy but now same story, it keeps telling me that 154 update available which I did auto update but I still get notification that I there is new update to 154. I cleared data and cache both for Huawei Core and Update app but still same story.
Please help!?!
You will need to use Hisuit Proxi & firmware finder to get more upto date firmware.

hi, should I update it using FullOTA-MF or OTA-MF only? thanks
Select Full, and use the check availability option to make sure its an approved for install as well, else it will fail.

thanks, another question is, will it wipe off the phone?
When I did mine, No. But remove or backup any personal stuff off your memory card if you have one, just in case. Note if you've done the GMS install, make sure you log into All you're accounts, ie YouTube etc first before upgrading firmware. Cause you won't be able to add later.

Update: Ok found it, it is via the advance button and paste the link there to check if it's approved or not.
Is this done via the HiSuit Proxy Advance button? how can i check if it's approved or not?
Use firmware finder to check it's an approved version.
Hi im having the same problem. I tried to manually update to version 10.1.0.161 after installing gms from 121. Still cant get OTA. Its been 2 weeks.

Hmmm we are all on C636. No idea what went wrong. Only difference is 4RP1 and 5RP1. Any difference in those?
Same situation here, I downgrade to version 131 o install GSM and now the phone won't update.
I had to update it using HiSuite and now I'm on 183 version.
Hope there is a way to fix the OTA updates on the phone.
getting regular updates after installing GMS via googlefier
Doing some research I have found what is happening:
On your P40 Pro, in the "About phone" screen you can see the build number and then a number between ( ), example: Build number 10.1.0.131 (C636E8R5P1)
The number after the C will tell you the version or region of your firmware, in the example C636 = version/region 636
When you downgrade using a different version/region you will loose the OTA updates on the phone, and this will only be restored after you install your correct version/region firmware.
You will need to find the correct version of your firmware and have the "dload" version, and install it from external card. There is a video showing how to do this, but the link on the video is for a version/region 636, if you have a different version/region it won't fix anything.
Once you have the correct firmware and install it, you will begin receiving OTA again. This process, at least on my phone, erased everything, so be aware of this.

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.

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.

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?

P40 pro downgrade - different device

Hi, just got my P40 pro and decided to install GMS. I've read a couple of guides and started...
Downgraded to EMUI 10 and lost USB connection. My device name changed from ELS-N29 to ELS-NX9. Did OTA updates up to EMUI 12 but still got NX9 as device name. Tried downgrading again via Hisuite and got error message Update Failed.
Shame that none of the widely available guides addressed any of the problems I have encountered, had to specifically look for them to see all the warnings related. I've noticed there are other ways to install GMS but downgrading still seems like the easiest option. Why ELS-NX9 though, and why Hisuite won't proceed?
First time downgraded directly to 10.1.0.154. Used correct files (C432, ELS-N29, R5). Now I am trying to follow THIS guide, but got error message from Hisuite.
What am I doing wrong? How to become ELS-N29 again (if it changes anything) and how can I install GMS and go back to EMUI12 the most hassle-free way? Got quite a bit of experience with flashing, using recoveries etc, so I thought it's gonna be sweet-as-pie job....

You used old tutorials. I think you can find many things on my thread here.
I'll try downgrading to EMUI 11 using Hisuite without Proxy then. I've seen your thread about fixing USB connection etc, but other people said over there that their device became N29 again after some OTA updates. Mine didn't.
I also wonder why my device originally was N29, but ny box says it's an NX9...
If I manage to downgrade to 11 through vanilla Hisuite, will I be able to follow the video I've linked above? It seems pretty straightforward, and If I only seen it before OTA upgrading...
Does my device being NX9 actually make any problems? Or it was just wrong Hisuite/random error then?
Edit: okay, I rhink I see now. So right now I should downgrade to the lowest thing Hisuite will let me, then Hisuite proxy to lowest 11 version, then I should be able to continue as per video. Correct?
EDIT: Okay, not correct, I won't be able to downgrade from 11.0.0.260 any further without OTG according to your guides. Don't have one at the moment.
I've also found this thread. Could I simply stay on EMUI12/HarmonyOS (whichever I have if there's any difference) and install GMS this way? If yes, I'd like t repeat previous question - does my device being ELS-NX9 now instead of originally ELS-N29 affect anything at all? Regards and cheers
Yet another edit: how is it possible that I downgraded from EMUI12 to 10.1.0.154 directly in the first place? Used newest Hisuite with Proxy. According to all guides, including yours, this should not be possible?

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

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
