try method 2: downgrade-huawei-android-pie-emui-9-0-to-oreo-emui-8
you have to cancel a possible update-download before you can activate downgrade window: 'Switch To Other Version'
if you have difficulties, i can upload the dload-folder (2,69GB)
p.s. i have downgraded 2 devices, so this method is save. From here device can further downgraded to unlock with dc-unlocker

Hi, I don't like Android 9 call recorder restrictions, so I decided to downgrade to Android Oreo many weeks before.
No other solutions works for me, until I discover your post.
Finally, right now, I restore Oreo in my P20 Lite using your recomendations.
Thanks a lot. :good:

Sorry what do you mean by the above? I'm currently on 9.1.0.274 and cannot get the "Switch to previous versions" option to appear? It just tells me that I'm on the latest software version.

Issue while downgrading stock ROM! ( System 8.0.046(0ECN)!!!! )

Hi Folkz,
I'm using ANE-AL00 Model and I tried to downgrade firmware using DLOAD method.
After successful dload method, i noticed that the build number is wrong "System 8.0.046(0ECN)".
And also some of the phone functionalities are not working (VolTE, Screen Auto-rotate, message app, etc)..
So I decided to dload back to the original firmware but the update process fails at 5%..
Now I'm in treble, because I tried my best to flash UPDATE.APP using different methods but every time it fails..
Can anyone help me please???
Please note that my bootloader is in Locked status.
+1 Me too, no have upgrade or downgrade actual version!

Can't downgrade from EMUI 9

Hi everyone,
When EMUI 9 was first released on Firmware Finder, I've updated my phone with HuRupdate, since then, my phone model has changed from STF-L09C432 to
STF-LGRP2-OVS, since then, I'm stuck with the build 9.0.1.157, even though I've tried many time to flash another update or go back to EMUI 8 but I never managed to do it. I've tried with official recoveries, dload folder and it always failed, I've also tried flashing with TWRP, ADB, HWOTA or even MultiTool 8, but it never changed. Last time I tried flashing Kernel I've got an error saying that the file doesn't match the size or the path of the Partition. Have I done something wrong? Will I ever be Able to go back to EMUI 8? And If I ever manage to do it, Will I be able to receive official updates? I've seen that EMUI 9.1 was released as I saw a Honor 9 Lite with it and I want to upgrade to it as soon as possible
I'd be thankful if anyone can answer one of these questions!
I have Honor 9 STF-Al 10, with the System Emui 9.0.1.179
Due to some bugs, i intend to downgrade to Oreo.
it is said the phone will be hard brick by the method of HuRupdater.
the only way to downgrade to Oreo from Emui9 is Hisuite.
I heard about the HiSuite method, but when I go in the update menu it only tells me that i'm using the latest official version (which is wrong), and it doesn't show me any "switch to other version" button to downgrade the phone

should use the proper Hisuite version on PC (mine is 9.0.2.301)
there is an option to switch to Oreo
I'm using the same one, is it written somewhere which version is the right one or do I have to try and retry each version?

you mean that your Hisuite is 9.0.2.301,
but still no option to switch to older Emui?
Exactly!
Not sure about If I should edit or double post but I thought that it also might be because my phone is Unlocked?
Wow I got exactly the same issue! Also STF-LGRP2-OVS but 162. No chance to downgrade!
I would be also fine with flashing a "normal" L09C432 version of EMUI but don't know how to..
Maybe if someone can post a TWRP Backup of EMUI 8.0 with no user data it could work since we can still have access to TWRP

Firstly I'm gonna try to go back to a normal version, not this OVS crap. Maybe if you go to a normal STF-L09 Rom, Hisuite is offering you a rollback?
I don't even know how to do that to be honest. Shouldn't it be possible just with fastboot and a FF rom?

I've tried but didn't manage to do it, all I got was a bootloop but if you want to try it then go on, I've seen some EMUI 8 roms for STF-L09C432 here

You tried to flash the EMUI 8 rom directly, right? I would firstly flash a "regular" (no OVS) EMUI 9 Rom and then try to roll back with HiSuite. I'm probably gonna end up with flashing the regular EMUI 9, lock the Bootloader and sell that crappy phone to get a flashfriendly Xiaomi

Be super careful downgrading to oreo because android P has rollback protection. I would recommend contacting HiCare and asking them to put you on EMUI 9.1. Although it's not a downgrade you might recieve and upgrade via OTA

I was planning to roll back and the get the updates the official way but if I can have EMUI 9.1 and also have the official updates like that then it's okay too, but should I contact HiCare or Honor directly
It's been a while , I've contacted honor for my problem, they told me that they were going to send my request to a higher cell or something like that, it's been nearly one month and still no answer from them :/

use a dload meant for C432 with a build version superior of the one you actually are.
Try https://androidhost.ru/TTy
use a working SD or usb-otg ExFAT formated
(test for error with h2testw windows app or with f3 osx/linux)
use stock recovery
boot dload mode

[Q] Help performing downgrade from 9.1 to 9.0

Hi guys,
I been trying some GSI roms lately and unfortunately I can't get the fingerprint to work on any of them... if any of you guys can source me the fingerprint line value inside BUILD.PROP would be a good help for me but the thing is I don't have much hope that it will work so I want to downgrade to 9.0 and then to 8.0. Via HiSuite the 'older version' doesn't show up, via dload the 'software failed' pops up... but via HRupdater in TWRP I have one update.zip that might lock the bootloader, it can really lock my bootloader?

Huawei P40 easy firmware downgrade guide / fixes LZ play chinese app install problems

So I've seen a few people here complaining they can't install google stuff on their phone because they've upgrade it to the latest EMUI version.
Here's an easy way to downgrade to a previous firmware. This works on the P40 version, but it should work on any P40 variant.
1. Download the firmware of your choice from the web. For the P40 european here's a link (it worked on my ANA-NX9 phone:
https://androidhost.ru/XyS
2. Put the ''dload'' folder found in the zip at the root of a usb stick
3. Attach the usb stick to you phone. I take it anyone knows how to do it. Shutdown your phone. Then press and hold volume up and power button until you get to the recovery menu
4. Select Update mode, then select Memory card/OTG update mode
5. The phone will verify and install the firmware
At this point you'll be able to re-install all the google stuff, no more errors when trying to install the Chinese app. Needless to say, disable automatic firmware updates.
For region C10 is suitable ?

I will answer my own question - Yes, it works with the region c10

Thanks for the downgrade guide @schumimtl
Has anyone (beside schumimtl ) already used this guide with the P40 and can confirm that that the linked firmware really works?
I don't want to brick my phone.
Hi, anyone know where to find firmware for ANA-NX9 C636E6R4P1? I did find anywhere but seems not found. Mostly is the EUR version firmware. Not sure if I flash to EUR firmware, it will cause any problem or not to my device.

Installing a custom rom

Hello
First of all, i know its risky and i don't mind it, because the emui os is totally ****ty. So i was trying to install a custom rom, but i ended up in a big unknowness. Recently I installed a custom rom on a samsung device, but that doesnt compare. My version of the phone is ANE-LX1, having EMUI 9.1.0.392. From what i know i should get an unlock code from dc-unlocker (however i totally don't know how ) and then just type some commands and get to TWRP, but from what i read there are a lot of errors so if anyone is very kind and guides me i will be very happy.
Take care!
Dc-unlocker doesnt work on emui 9. You have to go back to emui 8 to use it. And if i recall corretly you can't use emui 8 dload packages while emui 9 is installed. You can however use hisuite to rollback to 8. Dc-unlocker doesn't work in the version hisuite puts you to. So you have to downgrade little more with dload packages. I unlocked mine in build .125 or something. Just follow any youtube video demonstrating dc-unlocker once you're back in one of the compatible versions. Dc-unlocker is not your only option btw. You can use a tool called potatonv to get your code. With dc-unlocker you mess with software but with potatonv you have to short some pins on your phones board. Software or hardware, choose your poison.
Ok i understand now. However it's not the unlock problem, but after the unlock i don't know how to flash to TWRP. Can you please tell me what to do?
And one more thing @Frax3r . I was planning to install Pixel Experience 11 plus from @-Alf- , and it requires emui 9. If i unlock the bootloader on emui 8 i can upgrade then to emui 9? Thank you

Yes,
- via System (OTA) update,
- via HiSuite & PC
- using dload method & Service ROM (aka full stock ROM).
Ok thank you very much. I'll keep you in touch if something happens.
Cheers
No problem
