From emui 8 that rule is not necceary because in every build will present Data files for all version. Oeminfo in phone is trigger which files will be used if we talk about Ota. For service roms u manualy select data folders. Beside that on ffinder is appear b364, where is b363 or b365....
But it will depend of operaters if they dont know that they will still follow old rule, it is sad. On p10 plus from Emui 8 are same builds for SS and DS even in Serbia

My phone is WAS-LX1A

I installed the WAS-L21A_hw_eu. But i did not do the forced installation so i had the same problem as user PoLiThS
i was getting the same, System 8.0.0.046(0BUG)
i did a factory reset by pressing volume up button + power button and after that i did forced installation but i am still getting the same version System 8.0.0.046(0BUG)

Am i still doing something wrong?
Don't know if you fixed it but I had same untill 3rd flash normal dial upgrade still need 3button method .and it wipes phone still

Yeap, i fixed it with a few trials and errors... Forced installation worked with zip files. Lesson of the day read the red letters of the original poster, there are there for some reason.

Sorry, you selected wrong files, you dont know is your phone ss or ds, and you didnt follow my instruction for forced method.. See some previoys posts there are minimum 10 cases with that and how to solve it.
Regards
P. S I edited first post and marked red very, very important things.

I have dual sim LX1 and I have tried both 361 and 362 following the instructions, and selecting correct files as stated. I had Zero problems installing them using force method...

You should be aware that this is the FUT, the Friendly User Trial version, or how I prefer to say BETA that is not completed and has a variety of problems. Look in the "Release Doc" folder has file "release notes". It says that this is ROM TA (Tampered) ie. confidential. It is still an official version for testers, but not the one that is released to regular users. I'm afraid that after these, installations of OTA regular updates will not come up because this version is probably going through another test update channel that will not be active soon...

Anyway, it can be downgraded to Nougat with HiSuite 8 on B209 or B210 (depends on whether your phone is single card or dual card).

It is certainly a easy way to upgrade to Oreo without unlocking the bootloader, but are you really sure what you get?

I think it is more worthwhile to install a good custom ROM instead of this. :rolleyes::confused:

Man.... People from beta 321 got normaly Ota b362. Please, dont scare people any more here with termonuclar war or something like that. If rollback works why do not and regular Ota. Beside of that allways will be service roms for new builds.
Test ot not who cares for that. Build is approved by google, very efect rom for using for rollback from custom, for locking bootloader too, etc. So, if you dont want to use its ok but dont scare the rest people from here. . They enough waited for emui 8.

I have a question, do you have to have root to perform this operation?

It stops at 5% and there is an error.
I'm doing everything as it should and other methods as well

Did u follow procedure with update.app or update_sd.zip? Are u sure that you follow steps for emui 5 to emui 8?
─dload

│└─WAS-L21A_hw_eu for DS.... or L01A for SS

│└─update _ WAS-L21A_hw_eu.app for DS or L01A

├─update.app

What the heck am I doing wrong? After several successful downloads, once I unzip the update file I get the same kind of file which it does not look the same as on the instructions. Please see the photos.

So you didnt see that update.app.....last file in screenshoot.....
That file you need to extract out. Oh man, please I can not do basic things for you.... Take a look first page and extract files like as I did for emui 5 to emui 8. And.... Use PC for that. I never do that on mobile phone.

I apologize but I thought that last file in the photo is somehow corrupted. If that's how the file should look like, than perfect.
Thanks for your time and effort.

    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

    Screenshot_20180709-225829.jpg

    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

    Note:Sever is not so fast, so during downloading be patient.

    One example how you can use Service rom on Emui 8 when FRP accidently locked, oem disabled and rollback to stock and lock bootloader.

    Added new service roms B371 and B376!

    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

    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.

    I did it without a mistake, just read the instructions! Everything is well explained and supported by the pictures!
    It is not difficult to follow the instructions!

    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.
