I was able to rebrand my mate 9 running android 8...at least I believe it's fully rebranded, after checking the version, vendor, country, etc.
Anyways long story short, I follwed the hwota8 guide, got stuck after flashing OEMinfo with phone lock and FRP lock under bootloader and the OEM unlocking was greyed out. This left me unable to continue with the hwota8 guide.
I used Firrmware Finder and was actually able to flash the newest firmware that matched the OEMinfo file, and after finishing, the OEM unlocking is no longer greyed out.
Now, I've connected my phone to hisuite but under upgrade I don't get any option to rollback to a stable build so can I use firmware Finder to rollback to android nougat? (as it says my imei is approved for installation).
Update: Firmware Finder worked to do the rollback and I'm now back to running Nougat.
Do you mind giving a little more detail. I'm on a MHA-L29 (C567) US version. Running oero 8.0.0.371. FRP Unlocked, Bootloader Locked. I'd like to rebrand to AL0, downgrade to 7.0 and then run dc-unlocker to get my bootloader code, then rebrand back to C567. as dc-unlocker won't work for oero (8.0). Probably not possible but any information or details on what you did to rebrand and downgrade would be helpful.

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.
Hi all,
I got my new Huawei Honor V10 Saturday and it's an excellent phone! The phone updated itself to the latest firmware as soon as it connected to WiFi.
So now I have BKL - L09 8.0.0. 163(C636)
This is an important question that might help all new V10 people....
Would it be possible to use funky Huawei to downgrade the firmware to before the July patch /update and then use DC unlocker or HCU client to unlock the bootloader??
What's your thoughts on this?
Thanks for your help
D.
Do you have a code?
If you have a code.. You don't have to downgrade
If you don't have a code.... Sorry about your bad luck

He does not have one.
We were thinking, as DC/HCU used to work with Honor V10 (though on their site it only lists AL models, but I have seen someone use it to remove FRP lock), downgrading might be a solution. Sadly there are no dload packages for C636, but they exist for both C432 and C00 on androidhost.ru.
The thing is, if someone has already tried this and it failed OP wouldn't have to waste $45$.
So if someone on C432 who doesn't have an unlock code they could test downgrading to a May patch firmware or earlier.
I can provide instructions if you want to test.
This works fine on Mate 10/Pro as long as you haven't updated to a 02 xloader, then downgrading won't work as recovery will check xloader to prevent the brick that occurs when you flash a 01 xloader firmware on one with 02
I have a c675 on b161...I have a unlock code.. But am unwilling to root the finiky honor..
While I could.. It's not as easy or simple as my old Samsung.. Plus a lot of the features break upon flashing of other ROMs
While I would debloat tweak..I think the phone is fine as it is
Good luck...

OP doesn't have an unlock code. OP is asking if it would be possible to downgrade using FunkyHuawei to an earlier fw, and then to use DC/HCU to get unlock code.
Same way can be done on Mate 10/Pro, I downgraded (Though through DLOAD) from C432B148-SP1 to B142 and DC was working fine. On C432B145+ (June+) it is not working at all.
But I cant find any real proof that DC/HCU was working for global Honor View 10 prior to June firmware.
And as for debloating, there's not much bloat to begin with (thankfully). And preinstalled apps, including some of Huaweis own, can be uninstalled/disabled.
I couldn't live without root But I guess I like tinkering with my phone more than actually using it as a phone, lol
Good luck

You would have to use service firmware from androidhost.ru. I would downgrade to the version which is GPU Turbo. That one might work with DC.
You get instructions with the firmware, but basically just you unzip the file, copy the 'dload' folder from 'Software' to microsd and start dload mode (Vol up + down + power).

HI,
Thanks for quick reply. I will try your method later on but I would like to say that
I did try to downgrade to STF-L09_C432B130 from 4pda.ru/forum via SD card method in *#*#2846579#*#* but it failed at 5%
Any Idea what could be wrong? Also can you tell me how do I know that firmware is GPU Turbo? Thanks

B376 is the build that added GPUTurbo so you should be able to downgrade to that.
They added a new bootloader in that so you can't downgrade past it.
(You can technically but your device will hardbrick and you need to flash with TWRP or NoCheck recovery).
It may be possible because huawei started preventing downgrades in Pie, and I'm not sure if they've done so in later builds of Oreo too...

Yes, thanks I did managed to downgrade to 376 and tried to use dc again with same error 375. I did notice that my phone is not in device manager modem section as required by DC May this be a reason? Also what is downgrading in Pie ?

Downgrade to a previous build. Like B197 to B179. Can't be done in Pie.
You could try with the Handset ProductLine drivers found in DCs download section, but if it can read phone it means it should work if it's not patched in B376. So chances are they added it in B376, and you can't downgrade past it.
You didn't save unlock code last time you got it?

Unfortunately I could not find the code I was given before.
DC does not identify my phone by name and model it is just saying Found Applications port
Also in DC app on my phone there is no option for code by IMEI ???
I could not find a specific drivers for my phone in download section of Dc site. There is two files for Huawei Android phone drivers but I do not know how to instal them.

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.

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 ?

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.
I've been told that if I can downgrade to 8.0.0.374 that I could get the bootloader unlocked by ministry of solutions. Whenever I try to get that version from Firmware Finder, erecovery always downloads the .377 version.
Does this mean I can't downgrade?
Hello guys, can somebody help me?
I own a Honor 6x (BLN-TL10)
When I bought at 2017, I flashed my firmware to a different one cause I didn't wanted to use the chinese version, so I upgraded or downgraded to that firmware (BLN-C900B131) since that change, my device always recognize as hi6250, and when I try to install the original firmware on my device, It fails, on the update proccess appear that message, "Software install failed! Incompatibility with current version." cause I want to upgrade to 8.0 oreo, my phone right now is at android 6.0 emui 4.1.
Can you send the link of update file that you have used? And a screenshot of build number?
I'll attach 3 screenshoots, one of my EMUI and Android at the moment and the firmware's that I tried to install
The BLN-TL10 firmware that was the same that came with my phone when I bought
I've tried to unlock the bootloader, but Huawei phones bought on china doesn't have OEM unlock option enabled ;(
Idk if have some way to unlock bootloader without that option
