I have read about this problem on another thread but the problem was poorly explained and i couldn't follow to the processes explained on the replies, so i have created another new thread regarding this problem, because, in addition to being very useful for me, it might be even more useful for people that are searching for a solution.
I will explain briefly the scenario before talking about the problem itself.
I recently (1d ago) got my telephone blocked because of a Hard Brick that i managed to overcome using
DC Phoenix, from which i installed Emui 4.1 and then automatically updated via the built-in updater to Emui 5.0
As before my hard brick i was on a more recent build, Emui 5.1 (B394), i searched on the internet and understood that my current Firmware, "NRD90M test-keys" is a test build (or something like that) which can't be updated with the built-in updater.
So, i want to ask, in order to avoid getting bricked again, if there is a way i can update to the latest Emui available for my device, as in the current state the build, in addition to being obsolete, is also unstable and reports some compatibility errors, E.G. error retrieving microphone service when sending audio messages on WhatsApp, ecc.
i have heard of a method consisting of rolling-back the device to 4.1 again and installing 5.1 via Dload, but can you tell me how to do it more in detail?
EDIT:
Problem solved by rolling back to 4.1 b131 and then updated from internal updater app
Thanks in advance,
Federico

This Should Help You.
https://forum.xda-developers.com/honor-8/how-to/to-emui5-custom-roms-tested-openkirin-t3638445
I assume since you rolled back you have a locked bootloader atm.
Now i know these guides are somewhere but now that you mention it they do seem somewhat hard to find. ( on the app anyways)
But as for rolling back and then updating again via dload ( not TWRP) you need the rollback package and official firmware for your phone model.
Google and/or the guides section here should help you find those.
It should give you two zips containing an UPDATE.APP file each.
You need to put these on a folder named dload (one file at a time)on your sdcard( internal storage should do, too but no guarantees).
Create the folder if it doesn't exist.
Put in the rollback update.app in first.
Then power down and hold vol up+ vol down while powering up and it should flash the file.
Let it finish, boot up, put in the update.app from the firmware in the dload folder ( remove the old file) and repeat the process.
That should be it.
Also, you might be able to sinply dload the actual firmware from the test key build without rolling back but i haven't tried ( i think )
Should the dload process fail, you most likely have the wrong file in your dload folder, or multiple files.
I should mention that the rollback file actually brings you to a test.keys build. It's necessary to flash to full firmware afterwards and dloading the rollback file has always worked for me.
Personally i found that keeping the rollback update.app file for the rollback in the dload folder at all times is a good security measure. (besides the usual backups)

can you tell me what rollback package to use? i tried "(FRD-L19&L09, from Android 7.0, EMUI 5.0 to Android 6.0 EMUI 4.1, C900B300, Western Europe)" and didn't work
If you have an L09/19 it should work. Just make sure to flash the rollback package first.
Otherwise since you are on a test key build already, you might want to try to dload MM directly or if that doesn't work, try a stock nougat firmware via dload.
You could also try updating with Firmware Finder via proxy

If you are on a regular version of MM, as I understand it, you can update normally, yes

I am in a very similar situation and unable to solve this. Could some one help in this?
I had unlocked bootload, TWRP and Root. I decided to unroot and lock the bootloader. So, by following the steps mentioned in a different thread, I could successfully flash Marshmallow B130 through Force Update.
Steps followed:
1. Flash Rollback package
2. Flash Full OTA (Marshmallow on B130) from Huawei website which flashed
Now, the real problem started while trying to upgrade to Nougat.
I tried downloading B350 firmware from Firmware Finder. After slow download, it installs fine. But, after reboot I face below problems.
1. The OS is very sluggish and crashes so often
2. The build number says NRD***-test keys
3. No keyboard installed, so not able to login to Google as well.
4. At this point, Factory Reset, Wipe Cache Partition, rollback everything fails.
I had to unlock the bootloader and again force update Rollback Package and then to Marshmallow B130.
Now, I am stuck with B130. I tried downloading B340 and B361 thru Firmware Finder. Both of them installed but with the same result. I mean No keyboard, Test-keys build, Crashes
My Honor 8 model: FRD-L02
What should I do upgrade to Nougat? I have no confidence in Firmware Finder method. Any help appreciated
It's EMUI 5.0.1 not 5.1, I think.
Hello, i have a Huawei Mate 8 ,NXT-L29C900B200 and i`m stuck with this, i can`t update it, it`s android 6 with very ugly icons, can`t change themes and more. I want to upgrade, i follow this guide https://forum.xda-developers.com/mate-8/general/guide-how-to-downgrade-mate-8-emui-5-to-t3515202
and I can`t do nothing to go to an europe version, something like c432bxxx, i tried with Firmware Finder, by dns and vpn, with update.app method, hisuite tell`s me i don`t have any update.
I readed that c900 is global version, if helps.
I`m not have root acces, and can`t unlock bootloader, because i don`t have the key to unlock in fastboot oem unlock xxxxxx.
Help please? I keep trying for 3 months to solve this by mine, and i give up.
Update: I found this https://forum.xda-developers.com/mate-8/general/b582-nougat-update-links-t3699707
It`s flashing at 100% by dload update.app method, but seems nothing changed, i still have c900b200
Guys! Hello again... I'm still blocked with android 8.1 on elm29 sp5c900. I understand that c900 is global, Huawei still tells me that an update will come soon, but nothing. Erecovery doesn't find nothing on server and hisuite doesn't help me at all. Now the question... Is there a problem if I download an update file from firmware finder and install it with forced update (power plus volume buttons)? Can I brick the device, since I don't have a backup file or original software

Firmware downloaded through Firmware finder won't install via forced update, you can use service ROM (download though androidhost dot ru) and place it on usb OTG and force it. Or you can use patched Hisuite method to update https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146/page132
Yes it can brick, anything can happen but very unlikely, just backup your device through Hisuite before trying that if you want to keep your personal data(won't back up firmware, only apps, contacts etc.)
C900 hw/normal does not get any update.
Just force some updated base via dload package or via forced hisuite with dns spoofed.
Thanks for your answers! So... The steps will be... 1. Download "update full base. app"
2. Place it on root folder in dload folder
3. Update it via forced update (power button plus both volume buttons)
I've found on firmware finder update.app file. This works via dload method?

For dload, you ll have to use an USBOTG, exfat formatted.
On 8.1, Use a 9.0 dload's update.app .
Once on 9.0, use a 9.1 dload's update_sd.zip
Alternative is to use forced hisuite.-If so uodzte first to 9.0 then 9.1.

Thanks a ton. I will try with dload. Is more simple
Forced hisuite doesn't work! Gives me only update to android 8.0. Firmware finder on pc doesn't give me my version sp5c900, so I can't download any firmware. Now I don't trust FF on phone neither. What if this gives wrong firmware, since my emui version is not suported. ****

Meaning there is no update on hicloud server available for C900.
True. Damn huawei ****ty version.
Thx a lot #oslo for advices
I've spoked (finally) with someone from Huawei on chat, and after verifying my serial number she told me that my phone is a demo version. F%$&. So, no Android 9 for me. Still, my phone works flawlessly. Since I'm stuck on 8.1 I want to root it and play a little more. Can you give me an idea how to root it? Thanks

First, is this device is with an unlocked bootloader ? (and/or do you have the unlock code ?)
To check bootloader/phone status, boot to fastboot/bootloader mode :
Plug device to PC with Hisuite, reboot P20 and Hold volumeDown on P20 until it boot on white screen ;
What is your Phone status ?
Sorry for late response. Bootloader is locked.
"phone locked.
FRP UNLOCKED"
And I don't have bootloader code.
So you won't mind that dload packages are locking back bootloader as it is already locked...

Ok so i downgraded my huawei p40 from emui 12 to emui 10, but the problem is that i downgraded to emui 10.1.0.182, and, well i lost usb connection and fast charging, i tried updating via ota, but it says im up to date, i used erecovery, but it gives me the error retrieving package info, i tried dload with otg, but when i go to update in recovery it stays there for a while and then gives me the error ´´this update does not exist´´, so i dont know what else to do.
Edit: I used a transcend card instead of the one i was using and it now worked, i believe SanDisk cards also work; then i eventually got the OTAs, also when u get an OTA, you need to restart the phone in order to get the next one.
