First flash, need help!

Hello Everyone,
a friend brought me a Mate 8 from China and I want to switch from the AL10 version to an international one to get rid of the chinese base and to reintroduce google play and other apps to the phone. I simply dont speak chinese, you know?
The details:
Found Phone : HUAWEI NXT-AL10
Firmware : NXT-C00B197
I managed to unlock bootloader, get a twrp on in and to install SuperUser. The last two was difficult and I used the SRK tool from sonboons.
My first issue - I never could tick the function "unlock OEM" or so, because it is simply not shown in the "Developer Options". Is it ok to ignore that?
My second issue - Which Roms should I load onto my SDCard before wiping and installing them? When I look through the forums it always says something like "Before you flash this, go flash Version B1xx and then B3xx. Which Roms exactly need I flash in order to get from my B197 to a stock rom with google apps or a customized rom where I have google apps, minor optimazations and no bloatware?
If you have suggestions, you have my unlimited gratitude

This post may be useful for you: [GUIDE] How to switch to use stock firmware from other models
You can find all the official stock firmware here: Huawei Mate 8 Stock Firmware official thread
With regard to the bootloader, if you managed to install TWRP then your bootloader is already unlocked.

Thanks, the first link looked promising until I got to step 6 where the files of the oeminfo and custom.bin (C432) need to be downloaded - no longer available
Please help! I'll keep looking in the meantime...

Here is it for C432

latest update from huawei

Latest update from huawei did the following to my phone which was a rooted mate 8. ( losing root access was a given i guess )
No bluetooth
No google account
No file manager
No virtual keyboard
No alarm clock
Google voice set to default with no other alternative....AND it doesn't work!
Themes don't work.
Factory reset stops at around 22% with an exclamation mark
Pretty nifty for a 5 minute "Official" update.
What am i supposed to do with this lump of hardware?
I have my bootloader code, i have srk tool. I was originally on b190 buildnumber, then went to b200...and now this. Can someone please suggest which build number i need so i can then find the right instructions for the downgrade or whatever it's called.

U need Rollback package

if you have Huawei Mate 8 L29 model & if you are on Android Nougat then you need rollback package
Here is the link
http://consumer.huawei.com/sg/mobile-phones/support/downloads/detail/mate-8-sg.htm?id=91647
This is straight from Huawei and it is really a life saver. Only this file will work in dload method for you at this moment especially when you have NRD test keys or want to downgrade form nougat to marshmallow.
Download the file
Extract the update.app
Make a folder in your external SDcard and name it as dload
Place the update.app in that dload folder.
You can dload method 2 ways.
method 1
switch off your phone
press and hold volume up, volume down and power button all together
Once you see EMUI on your screen release your fingers from the phone.
method 2
open your dialer
type *#*#2846579#*#*
select - software upgrade - > SD card upgrade
that's it.
Once you are done. You will be on C900BXX build number. Then you need to dload another firmware. And which firmware you need to flash is based on your phone region and model. Is your phone previous firmware L29C185BXX ? if yes then you have to flash L29C185B180 or B192 according to your model. This is really important. Please share your complete build number.
Once you succeed in these steps then we can discuss how to move forward and what to flash next.
Hope you find this information useful and hope you succeed.

The region is Australia
Build number before this superb update was nxtl29c18b200
Now build number is NRD90 test-keys
Not that im being picky or selfish perhaps but is there a stable firmware which has low power consumption, themes work, better operation performance?
By the way, both of the above mentioned methods don't work. I got an exlamation mark and a message saying update doesn't exist after only 5% of updating

So you have NXT-L29C185B200 is that correct? you can check this in settings - > about -> build number
you are not in nougat so please do NOT use the file in my previous post. (that should be used only if you are in nougat)
At the moment you are in marshmallow EMUI 4.0
If you have unlocked bootloader and TWRP installed then flash L29C185B180 (stock firmware)
Link to that firmware - > http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v51422/f1/full/update.zip
For unlocking, installing TWRP you can use SRK tools. I hope you have SRK tools, if not you can get it from this thread

Link to the thread where you can find all Stock firmwares is here
https://forum.xda-developers.com/mate-8/general/huawei-mate-8-stock-firmware-official-t3391727
For flashing the firmware
1) Factory reset
2) Format DATA
3) Flash the zip file from the above link.
Android Nougat is Android 7.0 version. and the corresponding firmware's start with L29C185B5XX

I am sorry I should have been more specific. I meant before NRD test keys, your build number was NXT-L29C185B200 ? (C185 is region specific) C432 is for Europe.
And now you have EMUI 5.0? then you can use the rollback package.
Here is the link
http://consumer.huawei.com/sg/mobile...g.htm?id=91647
I thought you were in marshmallow so I suggested you not to use it. But if you are in Android 7.0 (Nougat) then you can use the rollback package.
This rollback package will downgrade your phone back to Marshmallow and then build number might say C900BXX. It should get rid of that NRD test keys.
And after that you have to flash the stock firmware using dload method
Link to that firmware - > [url]http://update.hicloud.com:8180/TDS/d...ull/update.zip[/url]
Correct link - > http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v52952/f1/full/update.zip

Bro, you can download the firmware using firmware finder..you can install it from play store..then choose your model and region. hope this will help you.
Edit: Sorry i just checked your latest firmware is what you're using right now..sorry bro..i think you can debranding the phone then flash new nougat firmware..you can choose either europe, asia or middle east for the region. there are tons of thread to do this..

i do a rollback but build number get c900 instead of c605 of my region. original insrtuction PDF speak about a file called SDupdate_Package.tar.gz someone know about this? Im using a nxt-l09c605

Download Full Package (system update)

I noticed some annoying bugs in Emui, so I thought "hey, why don't reinstall the OS" I tried it over HiSuite but it didn't worked out. After that i noticed the "download the full current package" button in System update. The button does nothing, is this normal? I'm just confused asf, the Mate 9 is my first device so idk. I also noticed that Huawei isnt offering the full roms anywhere where the public can find it easily. OnePlus & Samsung did a better job there... Is there even an easy way to reinstall the OS or update it manually?

Yes. It is normal when System Update doesn't download "full package", cause it checks current and choose not download same version.
And yes. Huawei doesn't offer full ROMs in easy places. They post all ROMs on HiCloud (Huawei Cloud Resource) silently. In a few cases they can post ROMs on Huawei official site, but it is too rare.
Huawei thinks that no necessary to told everyone that new version is coming, cause they are using method with OTA updates.
And no. There is no easy way to reinstall OS or update manually, but with some exceptions.
Current free method uses modified recovery to force update. It requires bootloader unlock procedure (unlock forces factory reset procedure). Additionally method requires some knowledge how whole process is running.
There is paid method also. It is easy in general and you should DNS setup only. But a few percents are choosing pay for service what helps people to install free ROMs.

Are you serious ??
@idealfall1
The easy place to download firmware is firmware finder on Google play store they have all Huawei firmware for all model...
Or we have this site
http://hwmt.ru/oth/HWFF/info/view.php?find_model=
Find your model number and download it.
And for finish we have a very very easy way to force re-installing firmware without root or flash recovery or paid solution or unlock bootloader... It's the 3 button method !!!
Create a folder in external SD card, call him dload and put firmware (update.app) in, turn off your phone press volume down + volume up + power in the same time and voilà
Sorry for my bad english

Huawei Firmware Finder is private project of enthusiasts. They don't host any firmware and only help people to find ROM in HiCloud. But question from idealfall1 was why Huawei isnt offering the full roms anywhere where the public can find it easily. Other manufacturers do it.

Do you have Mate 9? Did you try install something with 3-button method? I tried many times. It is not working.
In case of Mate 9 Huawei added special tag "UPDATE_ONLINE" in rom. And most roms are with this tag will not install via 3-button...

If you are right, so it is very good news!
5 or 6 months nobody can't install roms via 3-button. There are only 3 service ROMs with tag "offline_update".
What exact version do you have? I will download and check for tag.

Ok, conclusion time. Mate 9 users cannot update via 3-button because of this special flag/string. Does the firmware finder work? It's technically an online update, right? I'm a little bit confused... Firmware Finder found for me some FWs from june... Can I install them? Sorry I'm not looking through this mess xD

When I buy it they are in b126 version and upload on b138 but if the 3 button method don't work for update firmware like you say may be can work for him because he want flash the same version of firmware, are you fellow my reasoning ?

If you're using FF, you must know that it forces ROM to system update.
Workflow is simple:
1. Find ROM
2. Force to system update
System Update will download ROM by self, like update is coming from Huawei officially.
But Huawei prevents this trick on very new ROMs and additionally checks for authorization.
In it's turn, FF can check ROM too, tries to reproduce Huawei's routine.
So, if you want install latest rom, you have to use method with modified recovery to force update.
If you want install old ROM - force update via FF.
P.s. We are all huaweied

Yeah. Good idea.

Three button reset does not work with the Mate 9.
It just doesn't.
You can only factory reset if you're on stock.
That applies to ALL stock firmware as far as I know.

Downloaded Firmwares with 2 instead of 3 .zip-files

Hi there,
So in a nutshell i am wondering what to do with firmware updates that do not include the "data_public" zip file. I have received my unlock code recently and after a lot of messing about and some learning from mistakes, i've managed to finally run a stock MHA-L29C432B198 build while being on TWRP and rooted. During that time i have downloaded quite a few different versions of firmware and as all the guides are always talking about 3 zip files, i've discarded those 2-zip builds, but now i want to upgrade to B321 and the build i found (supposedly full ota) does not include the data public zip and i would like to know if there is anything to do about that - do i get it from somewhere else? do i just omit it? do i wait till it shows up somewhere? and what is the whole deal with sometimes including it and sometimes not?

Could you post the link to the firmware you found?
Anyway, you could try downloading through the Firmware Finder app, it will get all 3 files.
And latest for C432 now (Oreo) is B361 as of yesterday, I'm installing it right now.
Edit: Weird. Bootloader didn't get locked after flashing. Saves me some steps

The firmware finder app is my source, and i'll leave you a screenshot of the most recent versions on there - the topmost build (B198 fullOTA-MF PV) has 2 zips, the 198 fullOTA-MF has three, in spite of having a smalle overall size.
Firmware finder recommends to download the pv build to flash in twrp which is how i noticed this discrepancy. Where did you get hold of b361? Have you rebranded your phone?

Two-files ROMs (PV) are usually for rollback.
They are normal ROMs but you have to modify mankindtw's script for two files instead 3. Or use FF if they are authorized.

B361 is oreo. Found on pro-teammt.ru. You'll have to search for MHA-L29 (or L09) 8.0.0 for oreo.
Mine would be MHA-L29 8.0.0.361 (C432)

B361 is oreo. Found on pro-teammt.ru. You'll have to search for MHA-L29 (or L09) 8.0.0 for oreo.
Mine would be MHA-L29 8.0.0.361 (C432)

Two-files ROMs (PV) are usually for rollback.
They are normal ROMs but you have to modify mankindtw's script for two files instead 3. Or use FF if they are authorized.

Thank you both for the help, I appreciate it.

I need help! Mate 9 MHA-L29C636

It all started when my phone didn't get the Oreo Update. So I unlocked my bootloader, installed TWRP, downloaded an Android 8.0 rom for my phone.
I wiped data, system, boot, caches, and internal storage. I tried to flash it but is failed. So I restored the backup of system and boot. When I restarted the phone, it is missing many key apps, keyboard, file manager, and system update, and settings such as bluetooth is not working. Please help me! Games are running pretty slow and
the UI is ugly as hell, please someone help me!

You will hardly find a trustful source since FF does not host anymore, or what.
There is a generic Huawei Firmware Finder thread on XDA (not specific for Mate 9), find it and ask there, maybe FF moved or reorganized, maybe there is still a chance to use and download
Otherwise, you can try:
Search - AndroidHost.RU
Check multiple download links at the same time.
androidhost.ru
Enter MHA-L09 or MHA-L29 (or just MHA-L), depending what's your model and Search. Go through the list if you find something for c636 (there is more for v432, but it requires unlocked Bootloader and rebranding).
Most of the firmwares here contain official Installation instructions from Huawei, and a matrix from which build numbers they can be used for DLOAD - they are the so-called Service Repair firmwares for Huawei service repair shops
There were threads here about American users updating from Nougat and Oreo to Pie, find them and read. If you ask there, maybe spmebody can still answer (threads were still acive last year, not in 2018 like the the threads you choose to ask)
Good luck

Try searching for general FF thread on XDA and ask them what happened with their store
As a last chance you can try:
Huawei | Halab Tech Support
support.halabtech.com
They have scattered things around various folders and pretty complicated scheme (at least it was 2 yrs ago) how and what can be downloaded for free and what requires and which type of subscription
Two years ago I downloaded something successfully (without subscription), later didn't try anymore (btw, I have ended up with my Mate 9 and generally the Huawei phones)

problem that before had the Russian site Ffinder that had the ROMS and now has no more.
I managed to do the DLOAD only with Nougat that I have here and I don’t think anymore, I found other C432 C185 Oreo but I don’t find the C636
it's really hard
I downloaded this MHA-L29C636B378 (8.0.0.378) but when making the DLOAD folder it doesn't work
