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!

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?
Hello there, I'm trying to update my EVA-L09C605B135 to B380 (nougat) manually and I want to know if it is safe to do it. In Fimrware Finder I found aviable only B320, B360 and B380 and previous only B135 (the one and latest I'm currently using) for my CUST. Should I start by updating to a previous version or is it ok to go on with latest?
Edit: in FF B320 and B380 appear like "OTA" while B360 is the only that appears as "FULL", what does that mean? Should I go for FULL?
I have a Vodafone UK branded handset and went from B137 (MM) to B341 (Nougat) without any issues.
I had TWRP installed and flashed the update zips there, when i went to Nougat and temp lost TWRP, using the dload folder method worked too.
tl;dr - yes to your first question! IMHO.
I would say that ota updates are incremental updates, and if coming from one android version to another ie Marshmallow to Nougat you want to flash the "full" update zip. That's what i would do anyway...
Peace
Am also in need of that answer.
I'd tried so many ways but didn't work, so I thought can I downgrade to EMIU 4.0 follow the offical page of HW and update it to B386, is it possible?
And after I dload "HUAWEI P9 Rollback Package (EVA-L19, from EMUI5.0+Android7.0 rollback to EMUI4.1+Android 6.0, C900B300)", I have to dload EMIU 4.0 or I can dload B386 after that?
Sorry for my bad English
maybe use firmware finder? why should you rollback if want to update?
You need to flash B182 firmware package (http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v74994/f1/full/update.zip first after flashing the rollback package.
Then you will receive the first Nougat 7.0 firmware B383 via system update and 2 more updates up to B386.
Post back and a thanks will be nice.
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?

Did you find a way to rollback from oreo ?
hi i bought a l09 years ago and tried to root it and use custom firmware
this was not the succes i was counting on, so i rolled back a update.app
this worked fine but i kinda screwed it up, first i had emui 5.0 on it
but i managed to roll a b182 on it with emui 4.1.1,
i don't know how i did it or what my original software was but i can't find any update.app that will update it to 5.0 without an error
if any of you know how i can roll a 5.0 or higher on my phone i would cherish you always

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
