What happens/fails when you try to install c900 b300?
According to the following post it might be possible to debrand without rolling back but some details are missing (supposidely he flashed fullOTA-MF-PV c432 b386 by TWRP, you may ask him for steps):

Btw, c33 - is it France or Portugal or?
I have now eva-l09c432b398 with Magisk 15.3 beta and work correctly

Did you find a way to rollback from oreo ?
My P9 is currently running Nougat and I want to update to Oreo but in "About phone" it says I'm running Android 5.1 and EMUI 3.1 (I'm 99% sure I'm running Nougat). My phone is second hand and I've never rooted it but the last owner might've (if so then it got unrooted before it was sold). I have 4 months left on my warranty if it matters. Whenever I put update.app into a dload folder on my SD card I get an error at 5% when trying to update saying "Software install failed, Incompatibility with current version. Please download the correct update package." I use Firmware Finder to find the latest update and in "About phone" it says my build number is "EMUI-A168-L09C432B040SP11-log" so that's what version of updates I download. I don't get any OTA updates and Firmware Finder's DNC and proxy method don't work for me either. When downloading Nougat I did it manually (through dload) and I think it was some sort of beta or leaked version or something. I don't know what else to try but I just want Oreo on my phone. My bootloader isn't unlocked and my phone is definitely not rooted. I live in the UK so my phone is most likely from there too. What should I do or try?
Edit: I just tried updating my phone through Firmware Finder using the proxy but I get a package checksum error when I try
"Android 5.1 ... 99% Nougat" - Can you post the screenshot of your Settings/About (mask your IMEI) to see what are really your EMUI and Android versions. Also, scrolling down in About should show date (month, year) of the Google security patch - usually it means that Huawei built the ROM the same or next month.
You can also install from Google Play apps like My Device or DevCheck to see if they recognize it as Nougat
Googling for emui-a168-l09c432b040sp11-log finds that it was some early beta version (June 2016) for Android N, see eg (Chrome can automatically translate from Hungarian to English)
https://huaweiblog.hu/tag/emui-a168-l09c432b040sp11-log/
Frankly, I don't believe the phone under warranty was released with beta Nougat, rather that previous owner installed the beta (also I don't know is the phone covered by warranty with that beta N).
Look also to XDA, thread
https://forum.xda-developers.com/showpost.php?p=67931734&postcount=62
subsequent posts, how people who installed beta N (c432 cust or other custs like c900) went back to their official Marshmallow (or upgraded to official Nougat).
"tried updating my phone through Firmware Finder" - I don't find anything at all on Firmware Finder for EMUI-A168.
IMO, you cannot 'update' from your EMUI-A168-L09C432 to the regular EVA-L09C432 (good that it didn't brick your phone). Generally, going from one model/cust to another requires rebranding which is a whole different process, not just taking whatever ZIPs from Finder Finder and flashing them by DLOAD or by DNS/proxy in FF.
IMO, you must go back from your Beta N to official MM (from that time). Then (if it was EVA-L09C432) you will receive OTA updates to official N, or if necessary you will need to rebrand to eg c432 (since some other custs, like English Vodafone, got stuck at MM, there are no N builds for them).
Of course, rebranding (it voids the warranty), if necessary, requires to unlock the Bootloader.
Finally, Oreo is available only for Chinese cust, not even for European c432, and it requires (unlocking Bootloader and) HWOTA7 method, but for that you must first get rid of your Beta N (even rebrand if necessary - see above) to be able to start the HWOTA7 process towards the Chinese Oreo from some of the latest official Nougat builds, see
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
I'm not sure if HWOTA7 (that can be also used for updating Nougat builds ans rebranding from one Nougat cust to another) is applicable to your Beta N.
Try unlocking bootloader and use hwota7

It's probably not even neccessary, it is already c432, it should be enough to flash c432 b182 by DLOADvto come back to c432 MM, and then OTA updates will bring him to the latest c432 b50x Nougat - no unlocking bootliader needed
To the other side HWOTA7 might be risky as it requires EMUI 5 and it's not sure is it there in that early Nougat beta build

Use hwota7 to update to oreo is more faster and have face unlock

HWOTA7 directly from that b040sp11 might be risky as HWOTA7 requires pure EMUI 5 and it's not sure is it there in that early Nougat beta build - therefore going back to MM c432 b182 is betrer (google, you will find people from that time doing so from that Nougat beta)
Once at b182, OTA will bring him to the latest c432 Nougat (his warranty will be back) and then if he wants he can unlock bootliader and use HWOTA7 to go to Oreo (without warranty anymore)
Here you find EVA-L09c432b182 and how to flash it
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
Only the following steps apply for you:
2, 11, 12, 13, 14, 15
With the small modification for step (11):
- ignore the first sentence "Go back to main menu and reboot your phone - but not to system. " since you are not coming here from TWRP
- instead, switch the phone off and then boot as in the second sentence "You must press Vol+ and Vol- (in the middle) down until EMUI Software Installing begin and b182 will flashed" and continue with the rest
Upon the OTAs as in step (15), you will have official c432 Nougat (and your warranty)
Later, it's up to you if you want to unlock Bootloader (4 Euros needed for the Bootloader code) and to upgrade to Oreo by use of HWOTA7 method

What is not understood, there is no Oreo and there won't be for European, Mid East, etc custs
There is (official, no beta) but only for Chinese cust.
Using it, responding you from my P9 EVA -L19C432 rebranded to Chinese Oreo EVA-AL10C00B528

Thanks for confirming
Hello everyone,
I'm trying to upgrade my Huawei P9 Plus with Android 6 to Android 8.
Initially the phone had Android 7 and a Vodafone Branding, so I did a rollback to Android 6 and installed VIE-L09C432B161 and the VIE-L09C432B181 Firmware with changing the oeminfo to c432 with the SRK Tool.
Before I can rebrand the phone to AL10 with the Rebrand-Update-Tool-HWOTA7-P9-PLUS-VIE to install a Android 8 Firmware, I have to upgrade my phone again to Nougat with EMUI 5.
Unfortunately the OTA updates via the Update Manager are no longer available, so I tried to install different Nougat Firmwares via dload.
Every UPDATE.APP i tried fails at 5% or 37%
At the moment I have this B181 Firmware installed:
https://forum.xda-developers.com/t/vie-l09c432b181-vie-l09c432b360.4278905/#post-86382521
I also tried installing Nougat Firmwares with the HuRu Updater, but so far it didn't work.
Could anyone explain me please, what I have to do next to install a Android 7 Firmware successfully?
Thank you!
