Hello, some procedure or guide to downgrade a p8 lite 2017 dual sim (PRA-LX1), all stock looked, actually in BETA Oreo 8.0.0.321 (C432log) to official Nougat?
- I have used Firmware Finder but all rollback firmwares are not aproved for my IMEI, and the aproved not explicit rollback firmwares causes error (i supose dont format or create partitions to rollback)
- Hisuite, dont show option to rollback, in update, always display i am in last version. And the option of restore in fastboot ends with a your device not support restore.
- In erecovery the option to download last firmware a recovery, conects to wifi but always error when download.
Remenber, i am full stock, no twrp, no unlocked bootloader, or frp, etc,etc.
Can someone helpme, or the only solutions is wait for new Oreo oficial update or some milaculous aprovation for me imei in rollback firmwares?

huawei beta program, i think
Sent from my PRA-LX1 using XDA Labs
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

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.

Hi guys
I have rebrand my eva-l09 by chinese oreo firmware, using HWOTA7, and after starting up, all google service are missing, abd cannot intall it correctly, i trying all GMSInSTALL apk but nothing happen.
I tried to unlock bootloader via fastboot, a message showing up on adb command (unlock frp necessary...), can't enable OEM UNLOCK, always stay on grey.
Nothing is fine for me on this chinese firmware
Model : EVA-L09
BUILD NUMBER : System 8.0.0.046(0cs6)
EMUI VERSION : 8.0.0
ANDROID VERSION : 8.0.0
ANY SOLUTION TO INSTALL C432B504?

You say that you followed HWOTA7 instructions - did you really
1) Your screenshot shows model L09.
OP post #2 requores that you must rebrand (change location) from L09 (or L19, L29) to AL10.
You didn't rebrand, or it failed (how, why)?!
2) Your screenshot shows build number 8.0.0.046(OCS6).
Never seen any firmware like that.
HWOTA7, post #2, clearly describes that you must flash (after rebranding to AL10 c00), first b399sp17, and after b540.
Your build number is completely different?!
What you have is not result by following HWOTA7 instructions.
If you followed HWOTA7, you would have:
1) AL10 c00 b540 (not L09 b046 or what)
2) OEM/FRM would be permanently unlocked, with no OEM Loxk/Unlock option in Developers menu (not just grayed out)
3) You would have Playstore services preinstalled, you would just need to install Playstore apk
HWOTA7 OP post #3 describes how to rollback from (properly installed!!) AL10 c00 b540 Chinese Oreo back to Nougat (eg to L08 c432 b504)
But you don't have AL10 c00 b540, but instead something totally strange/wrong - I doubt that given eRecovery procedure will work for you.
You can try with HuRupdater (sorry, I never used and needed to use HuRupdater)

Sorry, really cannot help you then.
Unfortunately, since you didn't follow the guide but flashed some other firmware instead (you thought 'better' or what), you are in a specific situation, on your own, and only you should know or find how to deal with the phone and that Oreo firmware
As suggested in the previous answer, you may try with HuRupdater, but IMO, instead of further improvising (HuRupdater is very powerful but you can brick the phone), consider paying 15-20 Euros for DC-Phoenix or Ministry of solutions to safely downgrade to Nougat
After that, if you want Oreo, please follow the HWOTA7 guide carefully and in every detail (like others who now happily use the Oreo) - you will have stable Oreo AL10 c00 b540, debloated, fully working and with less battery consumption than Nougat
Also, rooted, passing SafetyNet, with fully working GApps, and ready for Open Kirin Treble custom ROMs (maybe they will work with your Oreo, too, but cannot tell you)
And if you would ever want to go back to Nougat, you would have a proven roll-back guide as in the OP post #3

I had the same issue just like you, even I read this post before I fix my phone.
First of all, the bootloader says the FRP-Locked, OEM Lock(or whatever says, i can't remember)-Unlocked.
On the Developer Settings the Oem Unlock option was greyed out.
Just like you.
So, reading this post [GUIDE] Debranding to C432 and updating to B361 (Nougat) for EVA-L09 i had a hunch...
What did I do to have my phone back?
1. My phone had the C432 oeminfo, so, I downloaded the dload-huawei-p9-eval09-eva-b136.zip (L09C432B136) in this post. Stock ROM dload file - P9 EVA-L09 B136
2. Copy the extracted dload folder to the external microSD card.
3. Now open the dialer app and enter *#*#2846579#*#* to open the project menu
4. Go to Software Upgrade > SDCard upgrade and confirm the update installation.
5. After the update, maybe shows an error at the final, let it be.
6. The phone restarts and boots with the L09C432B136, Android 6.0, and if you check the Developer options, the OEM unlock option is enabled. You can now lock or unlock your bootloader.
7. I need to update to the latest build and if i tried to check for an update, it says there is none.
8. I downloaded this firmware Download Huawei P9 B182 Marshmallow Update [Europe] I repeat steps 2-5, lock the bootloader, and search for an update... and update after update, I'm on L09C432B504 (Nougat)
Hope to help you...
Sorry for my bad english, I have no one to practice with...
Hello. I have a Huawei P9 EVA DL00, on it EMUI 8.0.0 / Android 8.0.0. Is it possible to port the EMUI 9 firmware from Huawei P10 / Honor 9 or another device to our P9 on it. We have Kirin 955, and on the Huawei P10 / Honor 9 Kirin 960. Who can port?

I don't know have you really been originally on that cust c451, or you rebranded to c451 as part of going back to stock / rolling back to MM
Anyway, c451 is a dead end, check on FirmwarFinder or at:
https://pro-teammt.ru/firmware-database/?firmware_model=EVA-L09c451
you will see that EMUI 4.1, b131/b132 are the last ever firmwares for c451
You need to rebrand to some 'proper' cust like c432 (European), c636, or so, to be able to obtain OTA updates up to EMUI 5, like it was described here:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
Rebranding to c432 is crucial. If updating to b182 as described there will fail, you should be able to reinstall c432 b182 (or newer c432) by eRecovery, or by flashing service restore c432b182 (but there are no service restores for c451 and no Nougat firmwares for c451)

Thanks for the reply,
No, ive been originally on c451. I dindt change anything on this device. I bought it at amazon almost 3 years ago, and apparently it was a "telstra" phone, i think from Australia, altought in amazon it said unlocked. Now im using Movistar network in Argentina.
Ok then, the question is, is there any way to know that after rebranding to c432 or another cust my device will work properly? i mean phone signal (the most important thing), camera, fingerprint sensor, etc.

Hardware is always the same, rebranding puts the other cust.
And with cust c432 you should receive OTA updates up to b504/b505
If not, for some reason (then it is possible to force DLOAD or HWOTA updates
Btw, responding you now from L09c432 rebranded to AL10c00 (Chinese), with Oreo b540 (Oreo was released for P9 only in China) and with some adaptations (Chinese firmwares are specific), everything works ok.
If you search throughout XDA, you will find many users (for all kinds of Huawei models) rebrand here and there, usually to c432 or c636 since they obtain faster and more updates (except for Chinese AL10, AL00, DL10 and alike that get first and farthest OTA updates, but Chinese firmwares require adaptations to become useful worldwide: bloatware, missing GApps, missing intl languages and configurations for intl carriers, and so)
Btw, didn't you previously say that you returned to stock (from custom ROM?) - in that case you must have Bootloader code (for rebranding you need to start with the unlocked Bootloader - have also OEM/FRP unlocked)
Edit: Btw, this is a wrong thread for discussing the update of stock MM firmware to Nougat

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
