b182 - this is not complete build name
Look into Settings / About and provide the full name/number of your build, like EVA-L09c900b182 or so
If your cust is c900 (as in my example), there are will be no updates
You must rebrand to c432 tpo get Nougat updates

Did you updated by OTA, or by the dload method? Whitch version of Nougat you have?

yes, with dload method. and now i'm want to downgrade to marshmallow again..
Me too. Roolbak erreur
You have to download the rollback package from huawei support, install the update.app from the rollback with the 3 button method, it's around 100mb, or so. Then download the marshmellow firmware, install it with 3 button, then you will have 6.0. You probably won't have the themes, it can be solved with twrp, and flashing the eu (or the region of yours) cust package.
I did that , and now I have c900b170. everything works ok except themes .
if I install EVA-L09C432B136 through dload method, should everything work ok? I will be able to get later the ota nougat update?

Is there a Nougat Build for L19C900B190??

Hi all,
I'm running a Huawei P9 with a build number of L19C900B190. I am not rooted, bootloader locked. Having an insane time trying to find a way to upgrade from Marshmallow to Nougat. I can't find any other C900 firmwares, so is it impossible for me to upgrade? In my desperation I have finally resorted to opening a new thread. Which regions received the C900 firmware? I am based in Singapore.
I understand another method i can go is to unlock my bootloader, root my phone, flash another oem firmware like C636 or whatever and then upgrade to Nougat. However I am trying to find a method that can keep my warranty intact as my device is just a few weeks old. If anyone can point out a firmware i can flash Nougat for my phone type via the dload method, I would be really grateful.
Hi,
Just sharing my experiences with you.. I had the same problem as you. Tried to flash C636B190 firmware from stock firmware (which is customised by Starhub I guess Cause build number is L19 C20B150 and I can't find any info for C20 build) and end up having C900B190 installed. Regardless of how many times I reflash, build number stay with C900B190 instead of C636B190. Although I had the B190 build, but fail to install Nougat update via Hisuit.
You can try to use Hisuit and PC to update to Nougat, see either it will fall at 1% or not. No harm will occur on your phone.. I tried many times. After giving up, I just send the phone back to service center and revert back to their original firmware.. And to wait for OTA.
Good luck...
I ended up sticking with the C900B190 FW as it's a pretty stable firmware for marshmallow. I've read around and with some help, found out that only way to go to nougat is to debrand to a C636 FW and then upgrade manually.

Version downgrade

I have searched everywhere but I didn't find a reply to my question.
A couple of days ago I have updated my phone LLD-L31 to the version 8.0.0.132 through Firmware Finder (it worked for me with proxy method) then I decided to revert back to the previous version 8.0.0.131. So I started reading guides to install a firmware on Huawei/Honor devices, I have downloaded the FullOTA package version 8.0.0.131 with Firmware Finder, placed it in the folder dload on my SDcard and started the intstallation in the project menu (accessible digiting *#*#2846579#*#* in the dialer), it started but suddenly it ended with a message "installation failed".
So my question is: how can i revert to the previous version of the software (or to the out of the box firmware installed on my device)?

You should have an option to downgrade in the about section/ the update menu of your phone if you did it right.
Otherwise you may need to use the HuRupdater Method.

Thanks for your reply!
I don't have this option, but if I remember well I hadn't it also in the previous version of the firmware.
So i can't install a previous version of the firmware simply downloading it an putting into dload folder of the SDcard?

Can you please specify why do you want to roll back?
Because most people just wanna upgrade to a newer version.Newwr versions will have better stability so it's recommended to keep the latest version unless you have some bugs.
I honestly don't know why the dload method doesn't work, seems that it doesn't work for most people.
I think you'll be able to roll back using HuRupdater. But that'll mean you'll have to unlock bootloader and flash twrp first. Then you can go all stock from there.
Here's a guide to the HuRupdater from @zxz0O0

After installing the version 132 I asked the technical support through HiCare and they told me that installing firmware with Firmware Finder could void warranty so I decided to revert to the previous firmware and wait for regular OTA by Huawei.

I'm not sure but I think you are on the latest build for your varient now so you won't be getting any updates untill a next build comes in.
I don't think you'll be able to roll back without the firmwares from firmware finder as you don't have an option to roll back.
The best option now would be to just wait for the next official build(might come soon as a small ota which has security patches) and then check if you are facing any issues installing which you won't as you are not rooted and dosent have an unlocked bootloader. So don't worry ?

Downgrading version Problem

Plz help me with downgrading my version 9 to 8

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

Upgrade from VIE-L09C432B181 (EMUI 4.1.1) to Nougat (EMUI 5) fails

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!
