Hi, I have a P9 Plus with firmware VIE-AL10C00B183 and unlocked bootloader. I have TWRP installed.
I'd like to upgrade the phone to nougat. I don't care if TWRP is removed and the phone locked again in the process.
How can I do that?
Thank for your help

Hi All,
As you know they already released the Official Android 9.0 Pie for Huawei P20 Pro in EU.
I have the previous version of Android 8.1 CLT-L29.
My devices is:
-Rooted
-Bootloader unlocked.
Can I update via OTA to Android 9.0?
Is there any problem during the upgrade?
Will be still rooted and bootloader will be still unlocked?
If not what is method to do upgrade and still have a Root?
Thanks for your help!
You need to flash stock recovery first.
You will not continue to rooted.
Your bootloader will remain unlocked
Thanks for your kind answer.
Do you think should I update to 9.0 or should I stay with the previous version?
I am not that sure about the root process at the moment and I don't want to loose it.
I don't think there are that many new noticeable features. EMUI looks and behaves pretty much the same.
Is it possible to downgrade to older firmware? At the moment I have this years September patch. Without rooting or unlocking if possible.

Every few months samsung will update the bootloader along with the firmware. You can only downgrade to an older firmware so long as it has the same bootloader version as what you are currently running. Not possible to downgrade bootloader even with root unfortunately.

Is there a list of firmwares where you can see the bootloader version?

The bootloader version number is written in the firmware version. Go to sammobile and browse the firmwares for your phone model to compare.
Example:
The latest October firmware for my s10+ is G975FXXS9DTI8. The '9' before the DTI8 represents the bootloader.
Im currently on the September firmware which is G975FXXU8DTH7. The '8' before the DTH7 represents the bootloader.
So when I decide to update, there will be no going back.
Hope this helps
