in the last few weeks, my Huawei p9 had many problems cuz of the last update!
my battery drain was increased, also the mobile shutting down when I used the camera even if battery more than 30%.
i thought all of those problems cuz of update not the battery, when I searched many times I found many guys written the same problems!
i contacted Huawei customer services, they told me that Huawei removed all software from their sites cuz of wrong use from some customers
here are how to Rollback your device without any problems.
1) First, download Android Nougat Rollback Package for Huawei P9 from here
middle east http://download-c.huawei.com/download/downloadCenter?downloadId=91646&version=357962&siteCode=kwen
europe http://download-c.huawei.com/download/downloadCenter?downloadId=91727&version=358124&siteCode=nl
2) Now create a folder dload in the root of your SD card and place the update.app file in that folder.
3)Now turn off your device.
4) Now press “Volume Up + Volume Down and Power Button” together. The update process will start automatically.
5) Now wait for some time to complete the process. Your firmware version should now be on “B300”.
6) Now download the full Marshmallow firmware from here
middle east http://huawei-firmware.com/rom/huawei-p9/eva-l19/324
or you can choose your eligible software from here
http://huawei-firmware.com/phone-list/huawei-p9
7) Now move the update.app file in SD card folder (Replace the rollback update.app file).
8) Now again press “Volume Up + Volume Down and Power Button” together to Downgrade Huawei P9 from Android Nougat to Android Marshmallow
9) Done.
This is the complete guide to Downgrade Huawei P9 from Android Nougat to Marshmallow. If you have any questions comment below.
This will be helpful. I have some question.
1. In number 2 do you mean to unzip the files and put the dload folder to sd card and leave update.app untouched?
2. And can you elaborate number 7 please? Is it the same update.app in number 2 and do I need to replace it to the downgrade firmware?
3. And is it okay to downgrade when my phone is currently network locked? Will it affect my phone or should i have it unlocked first? Btw my bootloader is still locked and I have no root.
I love you man! I nearly gave up! Thank you SO MUCH!
PS- Can we update the phone after rolling back? Or Will the OTA updates brick my phone?
It works indeed
Many thanks. It works perfect. Il had to use Hisuite to move the file in dload.
Now I get a notification asking me to update to emui 5. Ik don't want to do so of course but I can't stop the notification. Has somebody an idea ?
Don't understand guy.. am on oreo and never had any problems ..
Hello,
If I do the downgrade, will I lose my pics on my phone ?
Thanks for you feedback.
Reset Netwrok Settings
I was having the same issue ( sudden power-off when using camera or apps that use location), as well as the battery draining very fast.
I followed the steps suggested by Huawei to reset the network and (so far) it apperas to have resolved the issue. TBH its only been two days, but so far its looking good and did not require me to rollback or perform any other intervention. I'm too new to the forum to post a hotlink so you'll have to cut and paste it.

I hope it helps!
Oh god, thank you so much! u did the depression leaves me. I love you man <3
I managed to downgrade from 9.1.0.311 to 9.0.0.286 through HiSuite, but I want to downgrade even further, to EMUI 8.1(preferably 8.1.0.152?) as both EMUI 9 and 9.1 have very poor battery life on performance on my phone. I have the bootloader locked and my model is CLT-L09 C432. Before I updated to EMUI 9.1, I was on 9.0.0.270 and the option "Switch to other version" (EMUI 8.1) was available on HiSuite. Now it isn't on 286.
So, is there any way to downgrade?

I'm just in the process of doing the same.
Use DLOAD method to get back to 9.0.0.195, then hisuite will give you the option to roll back to 8. (You'll need a usb-c otg cable) - This wipes the phone, be warned.
Download 9.0.0.195 here:
https://androidhost.ru/T8h
Basic Instructions:
Unzip the package. delete the CLT-LXX that you don't need. (so remove CLT-29 in your case)
copy the files to the SD card. Place the inside a folder called dload. (so you'll have "update_sd.zip" in the dload folder, another folder under dload called "CLT-L09_hw_eu" in which you'll have another zip called "update_sd_CLT-L09_hw_eu.zip"
open phone dialer and dial *#*#2846579#*#* go to Software Update and then select memory card upgrade. (alternatively with the device off press vol UP + DOWN + POWER and hold)
cross fingers and wait while is does it's thing.
Phone should now boot on 9.0.0.195, and hisuite /should/ give you the option to go back to 8.xx.
...You may be able to go back to 8 directly through dload method, but I've done it in two steps to be safe.
Someone else shared these images to help explain better. (Sorry whoever you are, I don't recall where I got this link from!)

Thanks, but do you have that 9.0.0.195 locally by mistake? It seems that on my computer it downloads with 256k/s and it would take 8 hours to download completely.

That's androidhost.ru I'm afraid - it's painfully slow at the best of times Took me about 2 hours to download it from there earlier.
And it did finnaly work, fortunately. Now I am on good old EMUI 8.1 . Now I still have a question, would it be able to disable the system updates app? As there's always the red dot on the settings icon because it keeps telling me I have a EMUI 9.0.0.163 update. And I don't want to update. I turned off auto wifi updates download but I'm afraid to not force update it after some time.
I considered myself to be noob here . It's my fault not to did a lot of research as possible before I proceed my upgrade since I wanted my Huawei Mate 20 Pro (LYA-AL00) (chinese version with no finger print) to run Android 10 instead of 9 (Which I didn't know what version I was using but I believe it was the latest of Android 9 for Mate 20 Pro). What I did was following this guide >
https://ministryofsolutions.com/202...-emui10-android-10-stock-firmware-update.html
everything described in the above link seems legit so I immediately follow step by step and download the stock firmware almost 5 hours. After using OTA with dload I saw the screen install the firmware successfully. However, after few minute the phone boot up and it showed "your device has loaded a different operating system". In such case, I couldn't do anything with erecovery or even using the hstool here: https://forum.xda-developers.com/mate-20-pro/how-to/manual-upgrading-mate-20-pro-bl-locked-t3905924
by using the method above, i stuck at (install recovery or install system) where my phone screen show circle with 5% processing, then hi suite say failed recovery. In such case, I believed I might install the wrong firmware which isn't allow for my phone? If it is wrong why the phone allow to install the firmware via dload? If not compatible or wrong should not let user process the work.
Right now I stuck at (Your device is loaded a different operating system) and nothing I can do in erecovery including using wifi to update. Can anyone help? Thank you
Sorry for my bad english.
NEED HELP !!!! same problem on lya l09
i used hisuite to update my mate 20 pro LYA L09 to emui 10 ( the official way ) after the update was installed my phone was stuck in this black screen " your device has loaded a different operating software " . i tried using erecovery " get package info failed"
OTG DLoad package method, if works you will be fine. If not, try DC phoenix with a Dload package. Last time I experienced same thing. Then DC phoenix helps.
Hey Everyone!
i recently got a huawei P40 Pro, and was really dissapointed to find out we people in the UK didnt get GMS on newer huawei devices and tried all the methods to downgrade my P40 pro to emui 10 but i recently found a way to succesufully downgrade back to emui 10!
NOTES:
You can only downgrade back to 10.1.0.121 but that would be sufficient enough to install GMS
When downgrading back to 10.1.0.121 you will lose USB connectivity but you can either use the USB OTG method or the huawei browser for this tutorial
after downgrade and installation of GMS, google wallet would never work as it relies on safetynet and the device being play protect certified so you wont be able to pay in shops, but huawei wallet and curve will still work
Lets Begin!
I AM NOT RESPONSIBLE FOR BRICKED DEVICES OR LACK OF HUMAN DECEINTY BECAUSE YOU DIDNT READ IT PROPERLY
Requirements:
A USB-C OTG adaptor (i find the quick switch usb otg adaptor you get in google pixel boxes works really well, if you cant get one any sort of usb otg dongle would work from ebay or borrow one from a friend because you gonna need it as a requirement)
A Windows Computer
A huawei p40 pro (obviously)
STEPS:
1. if your running EMUI 12.0.0.xxx you will need to downgrade back to emui 11.0.0.260, you can just use the normal hisuite downgrade method by going into once you connected your phone
Update > Switch to other version > roll back
2. once you downgraded back to emui 11.0.260 you can use the dload method here to downgrade to the 230 release, that will allow you to downgrade further back to emui 10 because it skips the antirollback mechanism implemented into newer EMUI releases
3. once you downgraded back to the 230 release we can downgrade further
download these three files and keep them somewhere safe and accessible for later
Hisuite 10 here (DO NOT OPEN THIS FILE YET YOU WILL NEED IT FOR LATER)
Hisuite 11 here (INSTALL THIS VERSION FIRST)
HIsuite Proxy here (Use this version as i had better luck with this version)
Now follow these steps carefully to get hisuite running properly
once hisuite 11 is installed dont open it just yet, it will ask for an update, DONT update at all, all you need this version for is the app on the phone
once you connect your phone to hisuite to install the apk and it installs successfully, uninstall hisuite 11, by running the hisuite 10 installation (do not uninstall via programs and features, use hisuite 10 installation package to uninstall hisuite 11)
Once hisuite 10 is installed, dont open it yet and launch hisuite proxy, keep it open or minimised into the taskbar and go to this website to get the required files necessary as shown below, also acitivate an ad blocker as well as youll have to put up with a few annoying spammy ads
ELS-LGRP4-OVS 10.1.0.121ELS-N29-PRELOAD 10.1.0.1(C432R4)ELS-N29-CUST 10.1.0.8(C432)
Once these files are put into hisuite proxy select "Rollback OS" But dont select "Force Auth Bridge" as that tends to crash hisuite
Click SETUP to kick in hisuite proxy
once the logs appear all green and some yellow (Dont worry thats perfectly normal) Open hisuite by the windows menu or desktop
4. Connect your phone to hisuite and input the code shown on the phone
5. then once hisuite detects your device, go to update > switch to other version (if for any reason it says "no internet connection" please reboot your computer) and should show 10.1.0.121 as an update you can downgrade to, go ahead and downgrade to that version
6. once you downgraded to the version, download these bunch of APKs here but we only really need the GMS file in the zip file, the rest we dont need
7. get googlefier here and install on the device, once installed follow the instructions in googlefier to get past the first step
IMPORTANT: Now, when you install and get past the date setting screen you will notice you cant proceed any further, how to fix that is to install a modified version of microG for huawei devices in the ZIP file i told you to get earlier that has a bunch of APKs once that installs you should be able to get past the first step
8. once you install all google play stuff youll get constantly bombarded by notifications saying "Play services require an action" Heres how you can fix it
1. go to settings > apps > show system processors > google account manager and force stop the app and clear data
2. do the same with the google play store
3. do the same once again with google services framework
reboot device
go to where you saved the zip file earlier and install GMS.apk
go back into settings > apps > show system processors and then force stop google account manager and clear data
go back to google play, force stop and clear data
go back to google services framework, force stop and clear data
reboot device
google play should be fully working without that annoying "play services requires an action" notification but you will see "this device is not play protect certified" heres how you can fix it by the video down below
now your device should be downgraded and has all the google play services installed and fully working!
even if you choose to update to emui 12 youll still keep all your GMS stuff, tested that on my P40 pro running 12.0.0.270 and with the patch01 update
I HOPE THIS HELPS YOU!
Did you make the procedure or just copy it from..here, from...there?
I am asking because I can recognize my work, and you didnt mention that. And this is against the rule of the forum.

No I followed from my own experience, maybe because it'd worded differently in my end doesn't mean I copied it directly, don't jump to conclusions
Sure. 11 months later, but it is OK. Well done.

Hello! Because I answered to the same questions on different threads, I decided to create this thread, where I will provide my experience to you, in one place. The followings messages (2-7) contain all major info and tutorials links from this...
forum.xda-developers.com
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

Thank you for this. I was struggling but this solution worked for me in 2023.
Im strugling with downgrade now, but in my opinion region must be the same i think.Not R6 when eou have R5, and after it downgraded to R4 on 10.1.0.121.
hi everyone,
there is a reason why https://professorjtj.github.io/ doesnt work? it redirect me to yahoo website.

It is working. I have just used your link. Try other browser.
My P40 Pro runs exactly that build, 11.0.0.260, (C432E3R6P4), but my preloaded version has R6 in it, so that means I need to install a preloaded version that matches my R number. Instead of installing C432R4 I need to install the C432R6 in order to avoid bricking my phone, right? Im not sure
Right. But changing the R will not brick the phone.
Thank you very much for sharing this guide/tutorial + thanks to @badmania98 for his guide too: https://forum.xda-developers.com/t/...news-discussion-support.4346741/post-85860061
i was quite confused to which EMUI version (10.1.0.121 or 10.1.0.131 like a youtuber used) for which to downgrade to be able to install google service / GMS on my P40 Pro (ELS-NX9 C432)
Looks like it's working though for me
hi
thanks guys (Daniel and Sherwinter) for the unvaluable tutorials.
i've managed to make it work on a p40 with emui12.
Any chance to get rid of the "phone does not meet the security requirements" when i am trying to use google pay?
I've tried various things but no success...unfortunately there i have all my cards(and are quite a lot) and dont want to return to 8 banking apps
No. You can try Curve app ( from App Gallery) if it is available in your country.
understood.
multumesc

Brother, few days ago I tried this method and it's work for my p40 pro C636R5 version.
but today I'm trying to do this but it don't work. what should I do Now?

I have problem with my new huawei p30 pro.It was stuck on android 9 and emui 9 ,I tried every official modes to force the update.But I couldn't achieve that.
So I tried with hisuite proxy .I finded my Device model(VOG-L29) region: C431-HW-EEA , then clicked on add rom on firm Finder v2 .The version was the lastest 102.0.0.134
The procedure was smooth and I choosed the right ROM (100% sure!I already have that webpage open)Once finished the smartphone installed the EMUI 12 but once restarted the massage: Your device has loaded a different operating system! scared me .
Do I broke the phone? Is there a way to fix it without changing the motherboard?
Thanks a lot every help will be appreciated so much
Little Update.
I tried several methods trying solving this big issue.
1.Update from Erecovery trying to download and recover the package via WIFI
RESULT:the phone updated from 12.0.0.134 to 12.0.0.149 but once rebooted the
same result with black screen and the massage: Your device has loaded a different operating system
2.I done the same procedure of this guy
I also saved the log file of hisuite and here are the version before I made that mess:
* FirmWare_Base:VOG-LGRP2-OVS 9.1.0.240
* FirmWare_Cust:VOG-L29-CUST 9.1.0.4(C431)
* FirmWare_Preload:VOG-L29-PRELOAD 9.1.0.2(C431R2)
So The ROM I selected on huawei firm finder v2 was good(VOG-l29 102.0.0.134)
I succeeded to Recover and install the previous ROM,the 9.1.240,with hisuite and hisuite proxy
but once finished an error on the p30pro appear: Software install failed.
tried also the 10.0.0.195
I'm thinking about dload with otg or nm card but I don't know the procedure.
Could you guys help me?
Thanks
As the title changed I solved the problem of soft brick.
I write here the tutorial to help those who might have the same problem.
Requirement :OTG cable ,exFat formatted pen drive and the right Firmware to flash.
Create a dload called folder inside the pen drive and put in it the 3 Firmware's .zip file(base,cust and preload)
I specify that my p30 was bricked on version 12, so my first attempt was to load the version
VOG-L29 hw eea VOGUE-L29C 9.1.0.115(C431E4R2P2).
To flash the firmaware from usb pen take the phone off and hold the volume up button for several seconds while we connect to charge the phone .Connect the usb pen and from erecovery choose OTG update mode.
The result was an unbricked p30 pro but no fast charge and usb data tranfer and I can't get any type of update from OTA.
So I downloaded this version:
https://huaweidownload.com/download/p30-pro/vog-l29-2/10-1-0-123/
I flashed my P30 Pro once again, and of course no USB connection and fast charging. But system afetr few minutes started finding upgrades via OTA. Passed from 10.1.0.179 to 10.1.0.201. Of course I let it upgrade.
It was 11.0.0.138 first, then 11.0.0.174(last EMUI version before version 12 ) came and USB connection was restored.

Even if I am a programmer I am new in the world of android bricks and I spent 2 afternoons and many attempts to solve the problem.
The last problem concerns the creation of a backup point. I have tried different version of HiSuite and both windows 10 and 8.1.But I couldn't get data from phone
The solution is to install the Androis ADB inteface Drivers while the phone is connected to the PC. I believe that this way data information is injected to the phone as well as installed on the PC.
take the drivers from here: https://oemdrivers.com/usb-adb-interface
or here: https://www.drivermarket.net/adb-fastboot-drivers-v1-4-3-download-for-windows-latest/
once you carry out this procedure you fixed everything
