Unable to install stock rom Huawei P9

Hello!
I'm currently running on EMUI 4.1.1 (EVA-L09C900B182)
I downloaded the official firmware for P9 from Huawei website, extracted the UPDATE.APP with this tool https://forum.xda-developers.com/showthread.php?t=2433454 so i could get the stock RECOVERY.img.
I placed the UPDATE.APP in a dload folder on the root of my external SDCARD
Rebooted into bootloader, flashed the stock recovery (I had TWRP).
vol+, vol- and power button togheter, it tries to install but fails (software install failed! Incompatibility with current version. Please download the correct update package.)
I tried also with huawei firmware finder app and even if it says the firmware is approved for the installation when i verify with IMEI, it fails after (I tried EVA-L09C900B386).
I tried:
- with the in-app proxy, changing my wifi proxy to localhost:8080 and using the default updater
- downloading the package and manually moving UPDATE.APP in dload on my ext sd card.
What i would like to obtain is a full stock huawei p9 phone, so i could get the official android 7 and latest firmware.
Thanks a lot!

Best is to follow this guide and debrand the phone to C432.

I did something similar and ended up with C432B242 after some update with huawei firmware finder. Now I cant reach B397.. I've tried all the intermediate steps after 242: no luck. It fails during installation. Any specific instruction?

U have to downgrade to B182 and then upgrade to B360 FullOTA-MF-PV
When u upgrade to a new Android system u must flash FullOTA-MF-PV
U could try without downgrade first, but u cant upgrade to B397 because its not signed yet by Huawei, B395 ist the latest approved Firmware.

From b182 OTAs will lead up to b395.
b397 OTA is expected any day, meanwhile it can be forced (as well as the newer b398) from b395 by using no-check recovery:
https://forum.xda-developers.com/p9/development/eva-nocheck-recovery-flash-unapproved-t3705125

Update:
I reinstalled from b136 => b166 => b182
After that i tried b378 but now my build number is NRD90M test-keys
Will start again from b136 trying something different.

Can't update my P9

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

Lock bootloader again with oeminfo to try the warranty repair

Hi, unfortunately my p10 drop on the floor from an high of 8 cm... Yes almost 4 in an the camera now has a strange yellow border. Of course this issue happens only on the color camera. The b/w camera works well.
The problem is that I have unlocked the bootloader. Can I do something to prepare the phone for rma?
I've the original oem info and of course the unlock code.
Thank you in advance

Maybe downgrade to nougat and then ota update to oreo will help. When I made debrand had unlocked bootloader and frp. Then did ota update to oreo and now have bootloader and frp properly locked.

What guide should I follow for this?

For debrand I used this guide:
https://forum.xda-developers.com/p10/how-to/huawei-p10-debrand-rebrand-update-guide-t3691013
but I was doing it on nougat and I am not sure how it works with downgrading from oreo to nougat.
If you are already on oreo (and C432 region) you could try to use this guide :
https://forum.xda-developers.com/p10/how-to/guide-manual-updgrade-to-update-oreo-t3758286
tutorial 2 to flash the first full-ota oreo 8.0.0.360 from: http://pro-teammt.ru/firmware-database
but here is question to @Jannomag if it's certain that the script will work from newer to older oreo version. If so then try to use HiSuite to downgrade to nougat (for .360 it should be possible when hit firmware update -> switch to other version) and finally do the ota update to oreo. Be aware that I am not absolutely sure it will work, just suppose it should.

Downgrading to a lower version as Dec2018 security patches can be indeed a problem but this shouldn't cause a brick. The updated should fail flashing /kernel and /ramdisk from update files.

I tried to flash B365 oreo over B384 with tutorial 2, update started as usual then reached 100% and phone switched off totaly. Now looks like bricked, can't switch on, charging doesn't work, when connected to pc system shows unrecognized USB SER device. Is there any hope to unbrick it?

I have the same. Send to warranty and they fix this by replace the Motherboard. Now i can't unlock bootloader because no offical codes and DC unlocker not support newest security patch from Huawei. Otherwise Phone works fine and i have extra warranty to 2022 .

Downgrade

Hey,
how can I back from android pie to android oreo or nougat? I want unlock bootloader with dc unlocker, but on android pie I can't.

If you mean downgrade to Oreo, then the answer is no.
If the rollback option is not available with your HiSuite, you must downgrade to the lower Pie build number via dload method (flashing Service ROM aka "full stock ROM" for your model and REGION (Cxxx)! This process will erase all your data! You can also try chinese HiSuite (with an .exe extension instead of _OVE).
What is your model and build number?

Model LLD AL10
Build 9.1.0.173 ( C675E....1p4)
It was the last update i received.
Could you please provide the link for full stock rom which i need to flash through dload
