Upgrade to Nougat through dload?

Hi, i'm currently on C900B182, there's a way to upgrade the device to Nougat through dload without unlocking bootloader?
Last summer I succesfully installed a BETA version of nougat on EVA-L09 without any problem, then I did a downgrade because of the software bugs....
Thanks.

All stock, how to downgrade Oreo Beta to Nougat

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?

I had some questions hopefully can be resolved.
When there is an update in firmware finder can install it directly or it has to be through twrp or erecovery?
Am i able to update magisk manager without problems?
anyone got viper4anroid working or made audio experience better for this phone?
i understand that every time I update firmware ill loose root. Is there a way to not loose it?
Will update firmware make me loose all my apps and settings?
does downgrading firmware causing bricking?

Hello!
I've done the same thing. I didn't install TWRP so I can update via OTA. Today i've got 8.1.0.131 (C432) update. If you use TWRP to update firmware it will wipe your data. Magisk can be updated without problem. Viper will not work. No support for x64 audio drivers.

Go back from l29 to l04
How do i go back to l04 from l29 i was l04 at the start

When a new update is available you can just download it and flash it through hurupdater in twrp.
After updating just flash magisk again and you will retain root (also remember to reflash twrp/have the recovery.img file in the same directory when updating through hurupdater).
You will not loose any data or settings (unless the new firmware explicitly tells otherwise).

Hello Just one question. Did you use the same guide to get root and to debrand or was the same link used by mistake? I am asking because I am doing this to my phone and I am now in the debrand part. will really appreciate your help. thanks

Solution ndr90m test keys

I have a nrd90m firmware test as a result of a problem. I downloaded a full ota package as a solution from the firmware finder.
I want to ask if I install this firmware I lose all the data or not?
Another question if I wanted to install a custom rom instead, which would be the most suitable between openkirin or lineageos? Currently I have emui 5.
I have bootloader unlocked, root and twrp

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!
