Undo Rollback P9 lite? - Huawei P9 Lite Questions & Answers

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?

Downgrade Huawei p8

i have huawei p8 model number GRACE GRA-C900B370 marshmallow and i have been trying to downgrade with no luck, the battery life is horrible on this android version.
i downloaded the OS and extracted the dload file and all and when it starts updating it doesn't go past 5%.
any help would be appreciated.
Apparently, 'great battery improvement' with the latest B380 (can update from B370): [Firmware][Leak]Huawei P8 B380 - GRA-L09C432B380
Have you tried it?
Hi, what have you decided to do in the end?
If you still want to downgrade, what have you tried so far? To which version & build number do you want to downgrade?
When you say "i downloaded the OS", which version & build number are you referring to & where did you download it from?

p9 lite bricked, i need the b125 full!

I have installed the b161 update nobrand on my vodafone p9 lite, now i can't complete the initial setup, i searched for the vns-l31c02b125 full update, but i found only the ota, someone can help me?
I had the same problem last weekend,
Just install the L31C02B123 and the update to the B125 via OTA.
Downside is that you'll loss root and all. I hope you have a backup.
Regards
Try to flash c432 OEM info.

How to update from 3.1 to 5.1 EMUI ? Going to travel tomorrow early morning (urgent)

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.

VNS-L31C432B130 Firmware Android 7

Hi,
I have a rooted P9 Lite(2016) with Dual SIM and want to Update to Android 7.
But I can't update OTA because it's a rooted device.
My model: VNS-L31C432B130
I think i have 2 options: First is to unroot and update it OTA and than again root, because it's very important to root for me.
Second option is to download and install it manually.
But i don't know which firmware i have to choose. Only thing i know is that my device is VNS-L31 version.
There is so many firmware on the internet. Can i choose all firmware that begins with VNS-L31 or is there something to consider?
For example this version: VNS-L31C636B361
Which way is easier and which firmware should i choose?
thanks

The right firmware for your phone is L-31C432B370
L-31 is the phone model, if you flash firmwares with wrong phone model your phone will certainly soft brick or brick.
C432 is the region, for example c636 is Oriental/Chinese region, c185 is American or other (I don't remember), c432 is European. If you flash firmwares with wrong region, the phone will probably go into c900, the global region, And it would be difficult to restore to the factory firmware.
B*** is the actual firmware version. From 300 is android nougat, and the versions that end with 0 ("b370") are for dual SIM, those that end with 1 ("b371") are for single SIM.
Sent from my HUAWEI VNS-L31 using XDA Labs
l-31c432b370 how to install
Hi,
I have bricked my device today with this update https://www.androidfilehost.com/?fid=961840155545586862
I install it via twrp and than had the issue with voice command instead keyboard during setup. Fortunately I am now again back to Android 6.
Could anyone please tell me which one I have to choose and by which method I have to install it. I mean, should I install it with stock recovery or with tmrp.
My device is now unlocked and it's rooted with twrp.
Is that the right data: http://www.stechguide.com/huawei-p9-lite-b388-b389-nougat-update/
There are 3 files. One update.app and than Update data and update file. Should i install all 3 files or which one I have to choose?
Ps: Normally my system was Vns-l31c432b130 and now I have Vns-l31c432b161. But the phone is dual sim though.
Many thanks
Solved to rollback and update the usual way
Hello,
if anyone else has the same issue, this is the way to solve it.
First install the right rollback package and the stock Rom.
Here is a tutorial:
https://forum.xda-developers.com/hu...torial-rollback-n-to-mm-c432-devices-t3563955
After I was again on stock, I updated first to b370 and than again updating to b380 by Huawei system update app.
Again unlock and install twrp and su if you wish to.
Many thanks
