I bought it in telephone operator and it came with C521B140, via a tutorial pass to free C432 B136, and the mobile I jump update for B182, then through Huawei Updater pass to the B361 but I was not left to upgrade to B378 by OTA so I wanted to do it Manually and I got that error.

downgrade?

Hi guys
Someone has succeeded with downgrade from oreo to nougat ? I need go to huawei service, to exchange the display, but problem is "relocked bootloader"
So many tutorials here, which to follow for downgrade and have "locked bootloader" ?

You can use HiSuite or install the downgrade firmware through Firmware Finder. It has the normal Nougat version, but in the description it tells that it downgrades.

HiSuite tells me that I have the latest version so.. I cant downgrade from HiSuite, or if i can tell me how to do it please

@yungshadow
As M1chiel said, try with Firmware Finder.
Remember!! Everything is on your own risk!!
Don't know which version you have, but for me this is the roll back firmware...

Let's try. But.. still 0%

If you use proxy option, you have to set proxy in WiFi settings.
localhost and 8080
Then start download and wait until 4-5%, then disable proxy and continue download.

i'm using DNS. Now 11% XD

ok i'm finally have emui 5. Now i must rebrand ?

That I don't know, I already didn't understand why you wanted to downgrade ??

Look here: https://forum.xda-developers.com/p10/how-to/huawei-p10-debrand-rebrand-update-guide-t3691013/page38

Can't do anything with this trash device, even TWRP fails to install. What a waste of money!

I need to have bootloader status "locked" not "relocked" so i must rebrand to l09 and back to l29 yeah?

Ok guys
I Found a solution.
1. Downgrade from Oreo via FF using B185 (downgrade firmware) thanks
djg269 said:
2. Download some L09 firmware and install via FF
3. After installing I had bootloop (huawei logo, booting system for 10-15 sec and still restarting)
4. Enter eRecovery VOL-UP + POWER > Wipe data and cache
5. After Wipe phone said it's still L29 but now bootloader is locked not relocked
So i'm done now

Glad you got it fixed!!
Sent from my VTR-L09 using XDA Labs

I have a small question - in FF it says to make sure my current version is not "unlocked" - does that mean the bootloader or...? I just want to downgrade to B180 so I can install HuShed. I'm on L29C432B360 currently.

I don't remember this information. Could u send here Screenshoot with that dialog from FF ?

Same screenshot as post #4 -> https://forum.xda-developers.com/showpost.php?p=76556011&postcount=4

I used b185 from b360 with unlocked bootloader and I had no problems.
You should use b185(rollback firmware) and after this will be able toinstall whatever you want

Alright, last question - I have TWRP installed for 8.0. Will this affect the downgrade somehow? Because for example I can't install OTAs with TWRP. I'm sorry I'm kinda new to these kinds of stuff.

I didn't have installed twrp for 8.0 when i Decided to do downgrade so I think it doesn't matter but you can flash stock recovery for 8.0 if u want ofc.
Now i'm on 8.0.0.365(c432) but with official OTA update

Version downgrade

I have searched everywhere but I didn't find a reply to my question.
A couple of days ago I have updated my phone LLD-L31 to the version 8.0.0.132 through Firmware Finder (it worked for me with proxy method) then I decided to revert back to the previous version 8.0.0.131. So I started reading guides to install a firmware on Huawei/Honor devices, I have downloaded the FullOTA package version 8.0.0.131 with Firmware Finder, placed it in the folder dload on my SDcard and started the intstallation in the project menu (accessible digiting *#*#2846579#*#* in the dialer), it started but suddenly it ended with a message "installation failed".
So my question is: how can i revert to the previous version of the software (or to the out of the box firmware installed on my device)?

You should have an option to downgrade in the about section/ the update menu of your phone if you did it right.
Otherwise you may need to use the HuRupdater Method.

Thanks for your reply!
I don't have this option, but if I remember well I hadn't it also in the previous version of the firmware.
So i can't install a previous version of the firmware simply downloading it an putting into dload folder of the SDcard?

Can you please specify why do you want to roll back?
Because most people just wanna upgrade to a newer version.Newwr versions will have better stability so it's recommended to keep the latest version unless you have some bugs.
I honestly don't know why the dload method doesn't work, seems that it doesn't work for most people.
I think you'll be able to roll back using HuRupdater. But that'll mean you'll have to unlock bootloader and flash twrp first. Then you can go all stock from there.
Here's a guide to the HuRupdater from @zxz0O0

After installing the version 132 I asked the technical support through HiCare and they told me that installing firmware with Firmware Finder could void warranty so I decided to revert to the previous firmware and wait for regular OTA by Huawei.

I'm not sure but I think you are on the latest build for your varient now so you won't be getting any updates untill a next build comes in.
I don't think you'll be able to roll back without the firmwares from firmware finder as you don't have an option to roll back.
The best option now would be to just wait for the next official build(might come soon as a small ota which has security patches) and then check if you are facing any issues installing which you won't as you are not rooted and dosent have an unlocked bootloader. So don't worry ?

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

downgrade from 9.1 to 9

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
