[Need Help] I need to install Oreo (EMUI 8.0) Stock ROM in Mate 9 using TWRP 3.2.1-0 - Huawei Mate 9 Questions & Answers

Hi folks. Sorry if this topic has been covered before. I really tried to find threads with a solution but I wasn't able to get specific answers. Kindly help me out.
This is the current status of my Huawei Mate 9 - MHA-l29
My Huawei Mate 9, MHA- L29 is working okay, aside from a few bugs I noticed after upgrading to Oreo (EMUI 8.0) using TWRP last year (a previous version)
I am running Android 8.0 Oreo. The version reads System 8.0.0.42(00YC) when I check in the "About Phone Section". When I check this version using HiSuite, it tells me that is the official one.
I have unlocked the bootloader FRP...basically everything is unlocked.
I have installed TWRP version 3.2.1-0
I suspect I may have accidentally wiped out the recovery for my device, so if I tried to do a factory reset, it may not work. That is why I wanted to just do a fresh installation of STOCK ROM for Oreo.
Now this is what I need help to do.
I wanted to do a fresh installation of the stock ROM for Oreo (8.0) for my Mate 9 device. I figure stock ROM will be more stable and it will be the official one anyway.
The reason I want to do a fresh install is because I noticed the current version has a few bugs that kept recurring whenever I did a factory reset (issues with themes, calendar, etc).
I wanted to know if I can use TWRP 3.2.1 (currently installed) to do an installation of Oreo stock ROM for my mate 9 using maybe the SD Card. I saw somewhere that I can simply copy the files to the SD card and then use TWRP 3.2.1-0 to do an installation.
If the above is possible, what do I need to do?
If it is not possible to use TWRP 3.2.1, what can I do instead so that I install a new stock ROM without bricking the phone? Please assist.
Thank you in advance for your time and help.

Hi guys, I’m from China , and I have the phone P9 EVA-AL00(3G/32G) dual sim
I’ve unlocked my phone and flashed the ROM B168 version edited by Kangvip who is famous in Huawei forum, before I flashed my phone I followed the instruction backup the “System” “cust” and “boot” totally three folders of original ROM (also B168 version) with TWRP,
I think this can help us go back to the original System and OTA to the newest version.

Could you send me the method for Unlocking Bootloader, Installing Recovery, Rooting Phone, and then maybe installing a custom ROM if you have time? I have the EVA-AL00 also. I would like to install the European variant software. BETA Nougat 7.0 and 5.0 EMUI. Please let me know. Thanks again.

Tried rooting Honor 8 running Nougat and EMUI 5.0 and now I can't boot

I installed Nougat and EMUI 5.0 via the HiCare app on my FRD-L09. I had it running perfectly, then I decided I wanted to root. I hazzled around and finally got TWRP working, but I don't remember completely what happened, but something happened and I accidentally deleted the system partition. I have tried downloading the firmware for my phone and putting it on the sdcard in dload and then press Power + Volume Up + Volume Down. Unfortunately this failed immediately and I got something like "Install failed. Incompatible with your version." I still have access to TWRP so I tried flashing different firmwares (Marshmallow Downgrade Package, Nougat Firmware, Marshmallow Firmware) but they all failed. When I try to boot the phone now, I press the power button when it says my device can't be trused blah blah blah and it just says "Your device is booting now..." forever until it reboots and the same happens. Altough I can still access TWRP with Power + Volume Up.
So my question is, how do I get my phone back to stock firmware?

What do you want me to do? Download the rollback package and Marshmallow firmware or try the other version of TWRP?
So I found a Nougat Beta Firmware that is supposed to be installed on phones in India, but I flashed it via TWRP and I now have a working OS on my phone. However, there is one problem. My build number is "NRD90M test-keys" and there is no update option in settings and a lot of stock apps are missing (clock, backup & restore etc.). I guess I should create a new thread on how to get on the right firmware? I'm new to XDA Forums.

You installed a rollback firmware probably. I advise you to rollback to Android 6 and afterwards install the nougat update via the official methods.
Avoid open threads for every question, there is a search button to be used before shooting questions and opening threads.
Look for the rollback for your phone version.

I already found the rollback for my version and tried putting it in dload but it failed and said it was incompatible with my version.
So I just tried the rollback package again and it installed perfectly. I'm on FRD-L09C900B300. Doing the firmware itself in a moment. Thank you for bothering taking a look even though I pretty much managed myself. ? @ViCioPT

Just as future reference, when you flash an OTA based update.zip (not a full system update) in Twrp you also have to flash the data update to install the majority of the stock apps.

Install a working TWRP on Nougat and Root, also i need the stock rom

Hey guys, how can i check which Honor 8 FDR i have?? I want to roll back to android 6 if i cant succeed rooting android 7 https://forum.xda-developers.com/honor-8/development/firmware-huawei-honor-8-stock-firmware-t3470454 which rom is for my phone and what android version they are?
I can only see that is the model it says nxt-l29 its a Europe model i guess since it has multi-language support.
Every time i boot into the TWRP i can't see anything on the storage so i cannot install SuperSu, i have tried several recoveries like from this guide https://forum.xda-developers.com/honor-8/how-to/guide-unlock-bootloader-tested-root-t3443946

Help! Need to downgrade from Pie back to Oreo

Is it possible to downgrade back to Oreo?
I know there is ARB, but I read that some users are able to get back to 8.1 from 9.0
Everytime I try to flash an 8.1 Rom (Global Stable 10.2.2.0) via Fastboot, I brick my Phone and can only flash a PIE rom (Global Stable 10.3.2.0) to make it work again.
If I am missing something and it is somehow possible, any help would be highly appreciated.
You can try to flash oreo fastboot rom with mi authorized account. Maybe it works, i have tried and tested with RN5(whyred), not tried with RN6(tulip) yet.
As both devices shares same chipset, Hopefully it works
I got it working again. I just flashed Global Stable 10.3.2.0 with Android Pie via fastboot. After that, I installed TWRP and installed Global Stable 10.2.2.0 with Android 8.1 via Recovery and Wiped my phone.
I have no idea why it is working with twrp and not with fastboot, but whatever. I now have my Android 8.1 back even with all these ARB stuff :good:

Help for getting back to stock emui/region version or to installa a proper cRom

Hello,
I was running PixysOs on my Honor 6x till today but I decided to try to get back to stock rom mainly because with PixysOs Bt is not working properly and because system was not using the SD card so I was always running out of space.
In order to install PixysOs I rebranded the phone from BLN-L21 to BLN-AL20 in order to get stock Emui 8 version and flash PixysOs over.
I did a lot of tries with TWRP and MultiTool following different tutorial and at last I managed to boot into eRecovery which download and installed latest stock image for BLN-AL20C00 so actually the system has booted in a kind of Emui splash screen showing different options I can't understand as they are only in chinese.
Maybe we can start from scratch and someone can address me on how to get back to stock rom or how do install a stable custom rom?
Try dload the same stock firmware and see if you could manage to boot.
i was just writing an update.
I manage to boot the system and I can see that actually I am on Emui 8.0.0, model number is BLN-AL20 mobile network is not working as I am on China/Indian version (I think).
As far as I know I should now have the prerequisites to install a Pie Crom, any suggestion for a custom rom with working BT and SD Card?
Or do you think is better to get back to stock Emui going through rebranding?
As for rebranding I've seen that latest MultiTool no longer supports rebranding functions...
thanks,
Andrea.
Any hope to get an answer?
I would suggest to get back to full stock with everything functional. Once you fix, you can then switch to elemental rom. Haven't tried any custom ROM though on emui 8.
With full stock you mean Emui8 which will be in chinese and with no SIM support as I am on BLN-AL20 or do you mean to rebrand to BLN-L21 and to flash stock rom on it?
Actually I flashed original Emui8 and I have no SIM support.
If I have to rebrand how can I do it as MultiTool no longer supports rebranding?
I know it's an old device but is sad to have it dead on my desktop.
