downgrade from 9.1 to 9 - Huawei P20 Pro Questions & Answers

Hi guys
There is any way for downgrade from 9.1 to 9
My phone is mate rs porche design neo-L29

Hello,
You can downgrade the software version via HiSuite. Connect the phone to your PC with HiSuite, hit the update button and after the pop-up windows appears with "software is up to date" down below you'll find a clickable text "Switch to older version".

Wrong forum pal.
You need to be careful downgrading

P9 EVA L09C432B182 upgrade

Hi guys I got a second hand p9 still on emui 4.1.1
I've tried via updater but it says there's no update available, it seems to come unlocked already but then I dont understand why it doesnt find the update. Also tried connecting it via HiSuite but it doesn't work at all, when I try it says that there's no internet connection and that I should check settings.
How do I upgrade it to the latest version? I don't want to unlock it and all that stuff, is there a way?
Thanks in advance

Proxy method via Hisuite requires you to use the version that is linked with the guy that posted the 3 L09C432 nougat firmware updates.
You cannot use the latest Hi Suite version to do so.
Download the app "Firmware Finder" from the Google play store. It will allow you to check for later updates and whether they are approved for installation. It will then allow you to push the update to the phone's built-in updater app. If your phone is already on 432 you can do all of this without unlocking the bootloader.
Thanks guys, I managed to update via HiSuite using Huawei updater. I'm on b378 and both phone and HiSuite can't find any further update. Anyway I just wanted Nougat cause I didn't like MM on this device.

FINDER FIRMWARE for Huawei

Hello to all fellow mate 20 lite users,
I have questions regarding to firmware update, I have mate 20 lite SNE-LX1 C461 with the update of december and current build number for my device is 8.2.0.105, as I saw with Finder Firmware For Huawei, there is 8.2.0.132 version available for my device, is it safe to download and install firmware from Finder Firmware, and if anybody had tried such procedure on their device?
I tried yesterday and there was no problem. Check if the firmware is the correct one for your device. Use te Erecovery metod.

How can I check that?
Chose the update version, scroll down to the bottom and click: check firmware access- check availability and if it matches your model it will say "Firmware approved for instalation". If it says "Firmware not approved" tap a different update pakage. When you find the proper pakage use the steps shown in erecoveri update
Don't update if is not approved!!!
You must NOT to update your Mate if is not approved by Finder Firmware. Please be aware!
Hello, how can someone tell me how to use firmware finder? I do what I have read to put the proxy in the localhost wifi and the port 8080 and it connects to the WiFi but it tells me that I have no connection
The phone is Vodafone company in case it can be the cause

How to downgrade from 9.1 to Oreo?

I would like to go back to Oreo.
I found several tutorials online that say to use HiSuite version 9.0.2.301.
These say that the upgrade option in HiSuite should also allow to downgrade or "use the other version".
However, this options are never visible in my version of HiSuite.
Could anyone please share a succesful method for downgrading please?

P30 pro vog-l29(c815) Downgrade To 9.0

Hello everybody,
Can i downgrade my P30 pro vog-l29(c815) form Android 10 To Android 9?? Using OTG dongle (recovery mode) , considering that i have the Firmware.
Thanks in advance for your reply.
Later Edit:
I have successfully managed and figured out how to downgrade using Hisuite for PC.
I was on EMUI 10.0.0.90 (this is the last Ota update I have received, in order to get the (switch to earlier version button) I downgraded my EMUI FROM 10.0.0.90 to EMUI 10.0.0.186 USING dload, after that I enabled hdb and installed Hisuite on my mobile and checked firmware update button through it, and boom now I got two buttons, Update to EMUI 10.0.0.90 Again which I don't want to and switch to an earlier version which I did and successfully downgraded to EMUI 9.1.0.244 (android 9).
I wanted to downgrade since EMUI 10 has a bad performance and random ridiculous freezing issues almost in every app with no reasons, now I'm Enjoying my phone once again XD.
Conclusion: If you are on latest firmware update you won't be able to get the switch to an earlier version button on PC Hisuite, Insteadly you will need to downgrade to any previous EMUI 10 versions before you can downgrade to EMUI 9.
Happy downgrading to you all.
You can downgrade through Hisuite don't need any dongle.Just install Huawei hi suite in pc and you can do it from there 100% official

Hi m8,
You can't downgrade to EMUI 9.1 using dload firmware, you will get yourself a softbricked device. The only way is to use HiSuite PC version. If you can't find the Switch to other version, may i ask you how did you get EMUI 10 on your device? Did you used the firmware from other cust and also used a bypass method, like renaming all zips to update? Or other method?
Later edit: are you sure your cust is C815 and not C185?

Glad you sorted out. That's what i was going to reccomend you when you would confirm me that your cust is C185 or C815 ?. HiSuite is offering the downgrade option but not always from latest, therefore the need to downgrade to a previous version.
Don't forget to disable AUTO updates from Developer Options, otherwise you will be prompted to update to EMUI 10 and guess that it will auto download the firmware and maybe it will install it by itself

I've replied you on my dload firmware thread. Use dload firmware from my OP, downgrade to v190, then connect your device to HiSuite and check for an update. There it will be the option to return to EMUI 9.1.0.260. Be aware that using dload and HiSuite to downgrade will wipe clean your phone's data ?

take a look at this link:
https://www.pkrom.net/2021/07/vog-l29-c185-downgrade-from-1000-to-910.html.
You need an OTG cable,usb formatted pen drive.

You will lose the fast charge.There is also a procedure to restore it with the harmony cable on aliexpress
