P9 lite different Build number - AP version, can't update firmware - Huawei P9 Lite Questions & Answers

Hello I have 3 P9 Lite, all bought in Croatia from t-com/ t-mobile.
2 are the same dual sim version C432
1 is single sim C150
only one of the dual sim's got the official update to B371. And it's working fine.
I was trying to update the other 2 manually, with HiCare, and using firmware finder, but without success.
When I download via firmware finder and start the update I get the message ; Update failed wrong system version ( For B432 I was downloading VNS-L31C432B371 type: FullOTA-MF-PV)
Then I discovered that I got different build number and AP version (project menu- veneer Information's - version info);
1'st single sim : Build no. VNS L31C150B121 AP version: VNS-C900B121
2'nd dual sim : Build no. VNS-L31B432B160 AP version VNS-C900B160
is that normal? or is that the cause that I cant update firmware with firmware finder.
Also when I change model number in finder to c900 it doesn't find any firmware.
I'd like to update phones to B371 without unlocking them since they all have valid warranty.
Any suggestions, thoughts ?
EDIT: I was bale to update second dual sim device to B370

Yes, it is corect.
For uptading ok to B371 your firmware have to be B160/B161 and not B121

Latest build and OS?

Hi Guys,
I have a Huawei P8 Lite ALE-L21C432B170 Android 5.0.1 dual sim enabled. When I check for updates it tells me that there are no newer updates available for my device.
I was wondering if there is any firmware newer build that has stable dual sim enabled.
Also I wanted to know if I can install a newer version of Android while still having the dual sim enabled.
Marshmallow is going out soon by huawei.. But there are beta builds off 5.1.1 (no big changes)
This morning, I got the build B188. Atleast here in portugal.
B188 is released in Germany too
Hm, no Update for Single Sim 171 Firmware :/
Hi
I don't undestand everythings
If an upgrade (B188) is avalaible, it should be the same everywhere, avalaible in multiple langages ?
Could you give the link for B188 ?
I'me looking (for France) the L21C432B188
Thanks
I`m also trying to find some help on rooting my B170 Android 5.0.1 to B188 Android 5.1.1
I'm from Latvia, and still no B188 update :/

Can't update to B336

Hello, I'm trying to update to Nougat (C432B336). The beta is not available in my country (Romania) and I used Firmware Finder to get the update, but it gave me an error saying it is not compatible with my device (VNS-L21). I looked around and found something and now I'm confused:
Build number: VNS-L21C432B160
AP version: VNS-L21C900B160_SYSTEM (*#*#2846579#*#*)
One says C900 and the other says C432...
Can anyone explain to me what's going on? Thanks!

VNS-L22 Upgrade Firmware Finder

Hi,
I am currently on VNS-L22C636B150.
Firmware finder shows I can update to B153 and B360. I tried B153, it soft bricked my phone and when it did work, no Google services would work. Is it possible to update directly from B150 to B360? And if so, why are there 3 different files on firmware finder? Which one am I meant to use?
edit - the changelog for B150 and B153 is identical. However, B150 is EMUI 4.1.1, while B153 showed EMUI 4.1.2.
Your phone is frp locked?
