How to update from 3.1 to 5.1 EMUI ? Going to travel tomorrow early morning (urgent) - Huawei P10 Plus Questions & Answers

Hello Everyone,
I had a P10 plus dual sim VKY-AL00C00B152, Emui 5.1 with 7.0 nougat.
I did the rebranding via funky huawei with this firmware : VTR-L09C432B152 and VKY-L29C432B152
However, the model number became : D189-L29 and the build number is NRD90M test-keys.
There is no option to upgrade this firmware via the phone.
How do I get back to EMUI 5.1 with 7.0 nougat with an European Version of P10 plus Dual version ?
If possible, with HiSuite/HiCloud since all of my contacts info is on the cloud.
Thank you very much for this precious help.
Ldes.

You may find the answer in this thread somewhere https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
My understanding is that if you ended up with "NRD90M test-keys" then something went wrong with the oeminfo/cust change from the original to the new cust (C432) version. I may be wrong though.
It should be noted that VTR-L09 is for the P10, not the P10 Plus, so that may be the source of your problem too.

this is correct.
you only get EMUI 3.1 and NRD90M test-keys when the updated stuffed up. you will need to reflash the update via HWOTA.

Rollback to from NRD90M test-keys to MM (unlocked bootloader)

Please help!
Model: Huawei P9 lite VNS-L31 (NRD90M test-keys, unofficial!)
Bootloader: Unlocked
Region: Europe
I need to go back to an official version of Emui in MM. Where I can install TWRP, root, install official Huawei firmware with TWRP, do everything.
Please tell me what to do or send a link where people had the same problem and it was solved.
Thanks!

It's not that easy. I haven't seen a guide where you can solve the problem that I have. I can't downgrade because my NRD90M test-keys version is not official.

After Rollback from Nougat to MM C900 instead of C432??

Hello everyone,
This is pretty much my first post here, so I'm sorry for missing Info or missing knowledge of Android and things, I'm pretty much a Noob.
Yesterday I got the Update from MM to N, and obviously I updated immediately. But after the Update, I realized that I got NRD90M Test-keys instead of a solid build, i don't know how. So, I rolled back like the Guide said, first i flashed the Rollback Package, and after that the main MM. The thing is, instead of VNS-L31C432B160 I got to VNS-L31C900B160.
I wanted to ask how I get rid of the C900 and get back to Europe so that I can receive Updates. AND, With the C900 Version somehow I can't login to Google. (I'm on a P9 Lite VNS-L31, just to get things clear)
So essentially, I want to get back to Europe Cust C432, and i don't know how to do it.
Thank you very much for your help .
You should flash c432 oeminfo from TWRP

Undo Rollback P9 lite?

About a year ago a did a rollback on my Huawei P9lite from Android 7.0 to 6.0. Now i want to update it back to the latest version available.
The phone won't do it automatically and I also can't find the right package online to do it manually. Does anyone have some advice on how to do this?
The current build is VNS-L31C900B160 (It also used to be C432 for europe instead of C900)
The phone hasn't been tampered with aside from the rollback.
Thanks in advance

Will a factory reset help? Or will I still be stuck on C900?
