Huawei P9 Upgrade from EVA-L09C02B123 (Vodafone) - Huawei P9 Questions & Answers

Hi All,
I am currently running build version EVA-L09C02B123 on my Huawei P9.
This is the stock Vodafone firmware which was on phone when purhased.
I am experiencing issues with lagging/freezing, and unresponsiveness.
Some apps, such as Facebook, also randomly restart for no reason.
After a factory reset the same problems occurs.
I was hoping to download firmware version L09C432B136 and upgrade my device.
Can someone please confirm if it is possible for me simply upgrade my Vodafone firmware to this latest stock version, or will I encounter issues?
Thanks.

Follow these instructions if you want to debrand and still get OTA's: http://forum.xda-developers.com/showthread.php?t=3384903
I came from a C02, now on C432B166. Once I got 166 via OTA, I rooted again. I'll just keep an eye out for any OTA that I might need in future, but so far, so good with 166.

Thanks for the reply. Followed some of the guides on here and now on 166 and seems to be performing much better

L09C636/C34 'VERLIST.IMG' entries

Been working towards debranding my P9 from L09C34 (optus/au) to L09C636 (hw/asia).
Tried following all the guides and consistently ending up with C900 firmware, but managed to successfully roll back to the original C34, with version number displayed correctly on the phone.
My question is this:
In the C34 firmware that came with the phone (and that i've been using to roll back) AND the C636 firmware, BOTH firmwares have only two lines in VERLIST.IMG:
EVA_C900B000
EVA_Global
How then, does this part of the debrand process affect the version number displaying correctly, if both the successful original firmware and the unsuccessful C636 firmware have the same entries?
I had the same issue with wife's P9 Optus rom is based on the Global Version. EVA_C900 you need to flash both rom and data partition

Thanks. I managed to successfully get back to the Optus firmware with the correct version displaying - but I still haven't cracked the de-brand without it showing C900 firmware - from what I read, C900 is a cross-flash firmware and will not get OTA updates. My main concern was getting the Nougat update, which has apparently started appearing on the unbranded devices.
Did you manage to de-brand your wife's phone to C636? Does it show the correct firmware version in 'about phone'?
I tried to debrand my C34 to C636 as well but ultimately, I gave up on it and went to the debranded C432 UK version. There are plenty of info on this forum on how to do it and there is no lose in functionality and it works perfectly fine with the AU carriers. Realistically, apart from the build having C432 instead of C636, you wouldnt see or feel a difference between the 2 models. If anything, C432 will get updates sooner than C636 (as proven with Nougat).

Is there a Nougat Build for L19C900B190??

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.
Hi,
Just sharing my experiences with you.. I had the same problem as you. Tried to flash C636B190 firmware from stock firmware (which is customised by Starhub I guess Cause build number is L19 C20B150 and I can't find any info for C20 build) and end up having C900B190 installed. Regardless of how many times I reflash, build number stay with C900B190 instead of C636B190. Although I had the B190 build, but fail to install Nougat update via Hisuit.
You can try to use Hisuit and PC to update to Nougat, see either it will fall at 1% or not. No harm will occur on your phone.. I tried many times. After giving up, I just send the phone back to service center and revert back to their original firmware.. And to wait for OTA.
Good luck...
I ended up sticking with the C900B190 FW as it's a pretty stable firmware for marshmallow. I've read around and with some help, found out that only way to go to nougat is to debrand to a C636 FW and then upgrade manually.

Hi Guys,
after busting my head for a full day trying different methods of doing the firmware finder option and using the firmware finder proxy tool. i managed to update my locked ee (uk) p9 from an earlier build no. to build no. c440b142 (official) but my emui version only changed to 4.1.3 and is still on marshmallow.
can anyone tell me where ive went wrong and what steps i need to do? i thought that if i done the full ota tutorial after watching the youtube clip i would have nougat installed but it hasnt. i still have all my files and photos after the update :/
im lost....do i need to pay EE an unlock fee or do i need to do something else?
cheers
cammy
EE sent me a text saying my phone is already unlocked so what do i have to do now? do i have to get my phone rooted and pay money to do this?
cheers

Updating CLT-L29 8.1.0.106 (C605) build

Hello!
Got my phone today and am trying to update the firmware. I see that there are 2 newer releases of firmware verse what is currently on the phone, but trying OTA does not find any updates. Firmware finder tells me "firmware not approved for installation" for everything.
This is a Latin America region phone that I am using on Tmobile in the US.
I tried resetting the phone to factory and updating without putting a SIM in, but it made no difference.
Has anyone with this build received and update via OTA?
Any help would be appreciated.

I ended up paying for funkyhuawei. It did work very easily.
