Finally Service roms for Emui 8 provided by Huawei . Only for EU models - C432
Same Service roms could be used for upgrade from Emui 5 to Emui 8, and its a new possibility.
But please be careful for upgrading from emui 5 to emui 8 you should be on the latest builds c432B209 or c432B210, otherwise you will brick your phone!!! And... use force method for dload, otherwise if you use normal upgrade or select wrong files you will get wrong build 8.0.0.046(0BUG)!!! If you dont read this instruction as usualy and got wrong build just repeat procedure but now with emui 8-emui 8 ziped files and of course suitable files for your model.
Instructions are not so easy, so before you do anything, please read carefully Software Upgrade Guideline approved by Huawei.
My strongly recommendation is forced method with three buttons for unbrick, or rollback from custom roms, fix frp accidently locked, for locking bootloader, for upgrade from Emui 5- Emui 8 using dload method. With this roms you will get full stock firmware with locked bootloader and your warranty will not void any more!
Before you perform dload forced method with three buttons please make a backup using one of many solutions such as HiSuite, HiCloud, PhoneClone, Backup on SD, etc. Because forced method wipe all data on internal storage including photos,music, videos, apps, etc.

Remember:
LX mark "X" means 1 or 2
1- single sim (one Imei) , 2-dual sim (two Imeis, or converted models in some cases with oeminfo for dual sim)
Letter A- means 4gb models

L01- 3GB Single Sim
L21 - 3GB Dual Sim
L21A - 4GB Dual sim
L01A- 4GB Single Sim

For Emui 8 - Emui 8 upgrade, or unbrick, rollback from custom rom on Emui 8

On SD card put follow folder and subfolder depend of your model

└─dload
│└─WAS-L01_hw_eu
│└─update_sd_ WAS-L01_hw_eu.zip
│└─WAS-L01A_hw_eu
│└─update_sd_ WAS-L01A_hw_eu.zip
│└─WAS-L21_hw_eu
│└─update_sd_ WAS-L21_hw_eu.zip
│└─WAS-L21A_hw_eu
│└─update_sd_ WAS-L21A_hw_eu.zip
├─update_sd.zip
For example: I have dual sim , 3 gb model.... so I will create dload folder on SD and inside of dload place file update_sd.zip
and subfolder WAS-L21_hw_eu and in that subfolder put update_sd_ WAS-L21_hw_eu.zip, like this
└─dload
│└─WAS-L21_hw_eu
│└─update_sd_ WAS-L21_hw_eu.zip
├─update_sd.zip

For Emui 5 - Emui 8 upgrade, or unbrick
On SD card put follow folder and subfolder depend of your model

└─dload
│└─WAS-L01_hw_eu
│└─update_sd_ WAS-L01_hw_eu.zip
│└─WAS-L01A_hw_eu
│└─update_sd_ WAS-L01A_hw_eu.zip
│└─WAS-L21_hw_eu
│└─update_sd_ WAS-L21_hw_eu.zip
│└─WAS-L21A_hw_eu
│└─update_sd_ WAS-L21A_hw_eu.zip
├─update_sd.zip
Very important step for Emui 5 - Emui 8 ----You should unzip, for example for my model dual sim, 3GB,.... the update_sd.zip、update_sd_ WAS-L21_hw_eu.zip file, and get out UPDATE.APP to do upgrade operation, the file list as below:
└─dload
│└─WAS-L21_hw_eu
│└─update _ WAS-L21_hw_eu.app
├─update.app

Thank you so much. Hvala ti brate.Mada,malo ti je nejasno objasnjenje,dali idu zipovani fajlovi,ili se i iz nih vade fajlovi i koji?

Pozdrav drug! Just read carefully Software Upgrade Guideline.
Basically, zip files are going for dload on emui 8.
Files with extension app are going for dload on emui 5.

If I catch some time I will make tutorial.
Or if someone have a little more time to do that it will be appreciate.

Also with service rom your bootloader will be locked again, and warranty will not void any more.
I had relocked bootloader because earlier I used HWOTA method. After service rom my bootloader goes from relocked again in locked.

Hello there, I have a simple question.
I read the instructions but one thing is not clear to me. I have dual SIM LX1 model, and I am currently on B210.
Which one of these service roms do I choose, I mean 361 or 362, or it doesn't matter?
Thanks.
Hvala brate :)

It doesnt matter. But for Serbia you can use B361 because in b362 there is fix for VoLte. Everything rest is same.
From Emui 8 there is no rule for SS or DS and build number like on Emui 5.

If I upgrade by this method I will not lose the warranty?

No, you wont, this is official service ROM from Huawei (as stated in the post).
In the matter of fact you should flash this in order to gain your warranty again (if void before).
Cheers

No, u dont follow instrucyion. You've selected wrong model L01, L21.... which one.... or something else. Also I recomened forced method.... So...... Sorry, but must tell us full info about your phone, 3gb, dual, region, etc
With that build 046 u stuck there and no any more Ota if you dont repeat correct procedure.
