I have unlock code of my mate 9, and it works as well.. i try to downgrade my mate 9 to Emui 7 but it can't be downgraded since huawei security .
anybody knows how to downgrade mate 9 from Emui 9 to Emui 7 ?
bootloader change i mean xloader therefore only mate 9 oreo latest is the last downgrade firmware. If u use hurupdater or twrp or any method will brick the phone for sure. Dun try.
You can't! Don't even try it or your phone will die.

Yes, you can! I did it twice. You have to connect with huawei software, windows preferred, go to update. You have to perform 2 downgrades, 1st to 9.0.1 and second to 8.0xxx.

Oreo is not EMUI 7 (Though, there is no EMUI 7. Nougat was EMUI 5).
New, updated, bootloader was added in Oreo so that's the furthest you can downgrade.
But your method is the only safe way of doing it.
I've downgraded from 9.1 to 9.0 fine using NoCheck, but going back to 8.0 may brick (Depends on build you downgrade to)
Downgrading from 9.1 to 8.0 directly using NoCheck will brick and requires test-point to fix.

So, just to confirm please - even by TestPoint it is not possible to downgrade from 9.01 to 8.0 but before the Bootloader was changed (to be able to obtain BL code the 'old way', from DC)?

You can downgrade to board firmware using testpoint, then get bl code through HCU (which is needed anyway because board wipes imei and stuff). You'd then have to update from board to Oreo using dload. The dload needs to be from after bootloader was updated, else you will get a black screen only. (but you can use testpoint again to flash board again).
bonjour j'ai pu retrograder je suis a la version 8.0.0.379 mais impossible d'avoir le code via hcu

Hello guys,
I have mate 9 C636 B362 oreo.
The problem is am now living in europe
Which makes my phone unable to get updates through default system update and very slow to updates to go through firmwarefinder
My question is can i rebrand the mate 9 while I am already on Oreo to c432
Thanks
it is workable on Funky Huawei, but the price is quite expensive.
i've sucked on engineer mode when I rebranded china oreo version to European version, i was sure i turned off the FRP function, but when i finished rebrading , the FRP changed to lock status. i searched lots of way on website but not workable.
the final solution is use Funky Huawei with paid, it is quite easy but need money
I had the same issue with my mate 9 C185 region on Oreo not getting it's in UK. I used hisuite to rollback to nougat. Connect to PC and run hisuite update. It tells you you are on latest firmware but tab asks if you want to install previous stable firmware. This fully resets phone back to nougat - so do a backup. Once on nougat you can rebrand to c432 using hwota method. You will need to get bootloader code from Huawei first. This worked for me anyway.
I`ve a couple of questions regarding the whole boot-loader unlocking fiasco as Huawei will stop the official service from 22nd of july ,I`m currently on emui 5.0.2 on my BLN-L21 ,I`ve the following questions
1)I plan to install the GSI roms from Open Kirin but as they require the phone to be on EMUI 8 I cant do Anything right now ,so while I wait for the official release of EMUI 8 on honor 6x Can I generate Boot Unlock code now and then use it later?
2)Also on the official boot loader unlocking page it asks "Before EMUI" OR "Since EMUI" what option do I choose? As the phone launched with Emui 4.1? Thanks
1 You should be able to use it later.
2 Since EMUI

Sorry I forgot to put the fact it asks Since EMUI 5 or Before EMUI 5 ,I`m confused over the fact that the phone launched with emui 4.1 and now has emui 5

There is a possible workaround which I did last week.
First, I had upgraded version of Android 8.0 (MHA-L29 8.0.0.375(C567)(Stock Official) and possible to obtain the bootloader code when I start this process.
Here is what I did.
1. Downgrade to Android 7.0(EMUI 5.0) by using Huawei's HiSuite software
Click "Update" and select earlier version.
Current : MHA-L29 8.0.0.375(C567)(Official)
Earlier : MHA-L29C567B190(Official) | 2.45GB | Android 7.0(EMUI 5.0)
2. Using 3rd Party tool/service(about $5), I was able to get the bootloader code
In my case, I used DC-Unlocker tool(FREE) and purchasing 4 credits($4.71).
With the bootloader code, you can move to the next steps(root, custom ROMs, etc...)
Hope it helps!

In fact, I was not sure mine(from Android 8.0 to Android 7.0(EMUI 5.0)) could also downgrade, too.
(Yes, I did not expect to work to be honest with you.)
It would be good to try since it does not cost anything except your time (back up data and actual trying).
Again, I started from MHA-L29 8.0.0.375(C567)(Official Stock) to MHA-L29C567B190(Official) | Android 7.0(EMUI 5.0)
Hope it works for you, too.

Yes, I saw this before I try - Well I took the risk.
I can only assume that my phone was fine since it was stock & locked boot loader when I downgrade.
Now, my phone is unlocked boot loader & rooted with latest OTA Update applied - when OTA applied,
it locked the boot loader again which I had to unlock it again.

You had/have 8.0.0.375, the issues start at 8.0.0.377, and the OP already has 8.0.0.378, FFS.

Thanks & Really Sorry for misunderstanding & misreading.
Starting 8.0.0.377 and newer version can't downgrade it => it will brick the phone!
Up to MHA-L29 8.0.0.375(C567) and lower versions can downgrade by using Huawei's HiSuite software.
Hope this clears and provide right(safe) information. I do not want to provide dangerous (which will brick) information to all.
Again, Thanks:good: and Sorry for my mistake previously.

Hi, I have MHA-L29 8.0.0.370 (C432) security patch 1 july 2018, can i unlock the bootloader with DC-Unlocker ?
I tried to downgrade with Huawei's HiSuite (version 9.0.3.300_OVE) but the "Update, swith to other version" doesn't appear.
Up to which version 8.0.0.??? ( or security patch ? ) can Mate 9 be downgraded with Huawei's HiSuite
Up to which version 8.0.0.??? ( or security patch ? ) can DC-Unlocker unlock the bootloader ?
It seeems like you need to first upgrade from Nougat 7.x to Oreo 8.x WITH Huawei's HiSuite,
only then the "swith to other version" is available in Huawei's HiSuite to roll back from 8.x to 7.x ... correct ?

unfortunately there no unlock solution for us after gpu turbo ( from what i have read) and im plannig to sold my mate 9 as i have buying brand new xiaomi redmi note 7 and mi max 3.
this device has a very nice superb hardware but the locked bootloader really bad.
HI. I have a Mate 9 MHA-L00 with unlocked bootloader and installed KANGVIP ROM (Android 7...). I would like to try OpenKirin based PIE ROM, but in order to do that I would have to go back to stock EMUI and thus my bootloader would be re-locked. Is there a way to read the bootloader code again on an unlocked bootloader MHA-AL00? I am googling but can't find anything. I know there is DC-Unlocker but I would like to use that as a last resort. Thanks.
Hello guys !!
How are you today? because im ultra fine like all the days.
Well, i want to ask you if you can help me with this problem;
I Have a Smartphone Huawei, model "Mate 9 (MHA-09)", with Bootloader Locked, system Emui 9.1 = Android 9, FRP Unlocked.
For me, my 2 solutions are:
" Downgrade Emui 9.1 to Emui 9.0, then, to Emui 8, and finally, to unlock bootloader whit DC-Unlocker"
" Or change all the system with root, like the launcher, the notification panel, menu, etc"
I read about:
° HuRupdater
° Upgrade / Downgrade by SD Card With Dload
° Downgrade With Hi Suite 9.0 or 5.0 with FunkyHuawei
° Install TWRP whit NoChek
° Firmware Finder
° DC- Unlocker
° Xloader
° Update With SD 16Gb and not 32Gb
and i try, and i try.
and thats why i am here, i still can´t find those solutions, and i need help.
Can you help me please?

You can downgrade simply by HiSuite, see discussion (check also the earlier posts):
https://forum.xda-developers.com/showpost.php?p=80889343&postcount=3
That way you can go down to EMUI 8 but not earlier than to the firmwares with Security patch 07/2018 or later
And you cannot (and must not - people hardly bricked various Huawei phones, not just Mate 9) roll-back further because at that time Huawei changed the Bootloader
It actually means that you cannot go back to be 'able' to use old/good DC Unlocker - instead of DC Unlocker you will have bricked device that can only be repaired by Testpoints method
Also, only by Testpoints method you can rollback to Oreo, Security patch 06/2018 or earlier, that you can then unlock by DC Unlocker.
It was discussed in one of the threads here for Mate 9, about two months ago - please search
It was also asked and answered in another Mate 9 thread (during the last month or so - please search, you will find) about the available options to unlock Bootloader - but all goes down to the Testpoints, and some costs (to Halabtech, HCU or a particular Telegram group) that are about 30 Euros or more
Only those who never upgraded over Oreo firmwares with Security patch 06/2018 (that is, who still have the older Bootloader) can simply unlock the Bootloader with DC Unlocker for about 4 Euros ;-(

Hello mate.
I had tried before posting, but it didn't work.
So far the temporary solution I found (which I also tried for Dload and Hi suite, and it did not work, maybe I am wrong) is to perform a Downgrade from Emui 9.1 to 9.0, then you can perform a Downgrade to Emui 8.0. (but it is not possible to do it directly from 9.1 to 8.0)
I have an information puzzle, I still can't get to Emui 8, I keep reading, trying, buy 4 credits in DC, and surprise, they can't unlock it, and I already tried so hard, for so long that I'm seeing if I already sell Huawei, and I add it to my friends list "Never Buy again"
as ise with LG, Samsung, Xiaomi.
It is frustrating, he became a dictator huawei with his Sisteman "Emui" with which I can not even clean my quiet ass without bothering with his updates

Yes, exactly as in my post you cited. You downgraded from 9.1 to 9.0, then from 9.0 to 8.0, but you are still with the newer 8.0 sharing the same new Bootloader as 9.0 or 9.1 - the same new Bootloader that cannot be unlocked for 4 EUR.
You would have to downgrade further, to the older 8.0 firmwares (before GPU Turbo and/or earlier than Security Patch 06/2018 - they usually correspond to the jump from the old xloader to the new one).
But such downgrading is not possible by e.g. HiSuite, and if you enforce it by DLOAD, you would jump to the band wagon with several other users of various Huawei devices who similarly wanted to 'cheat' - but instead of unlocking Bootloaders for the cheap 4 EUR, they hard-bricked their phones.
There is only one method to downgrade to that old xloader.img - TestPoints: it requires to open the phone, to shorten pins on the TestPoints at motherboard and then to use a special loader and driver by Huawei to flash the board image. You may have problems to restore IMEI(s).
If you are interested about, search on XDA and outside, you will find the guides.
Actually, there were even instructions here (not very detailed - requiring further research for resources), under the Mate 9, Q/A or Guides section (e.g., I remember that I have asked for how-to at late Aug or early Sep, got a short answer but I never pursued to try it on my own)
E.g., attached is a photo of TestPoints pins for Mate 9
finally, I have the solution

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

Thanks before
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
