Try HiSuite. There was a downgrade option for 9.0 users

That option has been removed with EMUI 9.1.
You may try FirmwareFinder method, but the given DNS adress didn't work for me, so I couldn't get a validation for the downgrade in eRecovery.
Still looking for a method.

Firmware finder will definitely mess your phone up at downgradeing. Don't try it.

download the stock firmware and put in inside sdcard/dload folder..flash it..make sure its the final oreo version.

How did you get on with the downgrade?

Can you tell me what is the version?
I'm also still looking for the rollback file. I have the FRD-AL10 version now on Android 7.0!
The Build-Number says NRD90M test-keys. I really need help, I'm searching since 2 days and was also writing with the support.
Thx for your help

Frd-al00's rollback is different from l04.
If you are in official emui 5.
I suggested you download hisuite in huawei website, and then connect your phone to pc, click system update in hisuite, you will see rollback button.

I have REBRAND AL00 to L09 by https://forum.xda-developers.com/honor-8/how-to/guide-honor-8-to-frd-l19-t3632220
Pls help me from L09 back to AL00?
I don't have back up rom AL00, only back up OEM info
Interesting discussion. so is 360 the only version you can do a straight flash back to in TWRP, or is there a newer version?
Can the stock rom be rooted using Magisk or SuperSU - can one of them be flashed immediatedly after flashing the update zips before rebooting, while twrp is still loaded?
Rommco05 said:
B360 is first stable Nougat for most models and I starting from this firmware and after update device with OTA. Yes supersu works, I was using modified supersu wich is posted in twrp thread by openkirin team and I always install them after first boot to rom
Click to expand...
Click to collapse
Yes, but if you flash back to b360, it doesn't take OTA updates, and I don't want to relock the bootloader.
The main issue I have with stock is the inability to turn off the battery charging LED - it really annoys me.
Help.
Been messing around. I'm now on b380 but camera doesn't work and updates don't work. I've lost twrp, and if I try to install it it fails, although my boot loader says it's unlocked. It's there a way to flash the restore from a pc if I can't get twrp reinstalled?

Eventually resolved by downloading rollback package and b331 from Huawei site, and putting the update.app from each in dload on the sd card and forcing flash.
Frd-Al10 has native CallRecorder?
Hello. After update requires huawei ID log and pass. Can't use phone.
Does anyone know hot to fix it? Can't find rollback

Don't u get OTA updates?
Sent from my Honor 8 using XDA Labs
He can't get OTA update, since he is running on rollback package OS, you have to flash rollback package and firmware package (Marshmallow). After doing this, you can easily search for updates via Update in Settings.
That means you're stucked on FW C900 which is just for rollback to EMUI 4.1. Download full package from Huawei website and do the dload method to flash the correct FW.

I still haven't got the update process to work, i've had problems with every possibile way:
eRecovery update - during the download process after a while eRecovery automatically reboots the phone, and when i re-enter the recovery and start the update process it resumes from where it left but at the end of the process the validation fails, this does not happen if the size of the update is smaller, like an 300mb ota successfully updated my phone. I assume it has a timer before it stops the update.
DNS update - from system updater it finds the update but fails to download it
Proxy update - not working
Is there a way to download the files and then update?

Any really simple guides to updating my Mate 9?

I bought my Mate 9 from China and it's never updated as you can see
I need to manually update it by the simplest method possible
I can unlock the bootloader but that's about it.
I've tried various ROMs but they all fail to load
I think it might be simpler to root it and then install an later rom
