L19C900 update problems. Help appreciated.

Hi all,
I'm running a Huawei P9 with a build number of L19C900B190. I am not rooted, bootloader locked. Having an insane time trying to find a way to upgrade from Marshmallow to Nougat. I can't find any other C900 firmwares, so is it impossible for me to upgrade? In my desperation I have finally resorted to opening a new thread. Which regions received the C900 firmware? I am based in Singapore.
I understand another method i can go is to unlock my bootloader, root my phone, flash another oem firmware like C636 or whatever and then upgrade to Nougat. However I am trying to find a method that can keep my warranty intact as my device is just a few weeks old. If anyone can point out a firmware i can flash Nougat for my phone type via the dload method, I would be really grateful.

Oops. Sorry mods could you delete this thread, moving to questions and answers part of the forum.

You flashed a wrong update file then you got c900. Which cXXX were you using when you buy your phone? You should find it and flash it. C900 is cross flash code, no region for it.

Here are the oem infos.
Me, i wanted to convert it to dual sim, when i flashed the oem info it bricked actually, it was entering erecovery only, no TWRP, and prompted me to download and install the original firmware, i did so, the first time was a failure but on the second attempt it almost booted, imade a factory reset and a clear cache and it works fine, it was converted to dual sim, and the firmware that downloaded was not the original one, but the one that matched with the oem info that i had flashed, that's how i did it.
