There are different custs, different builds. How could people help you if you don't provide crucial info, what exactly is your firmware - like EVA-L09 c432 b394 or what

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.

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.
As asked in the title, can I update a rooted Huawei P9 with custom recovery to Nougat update?
And if not, what should I do in order to update? Remove root and custom recovery? Factory reset?
Thanks in advance
What the firmware version do you have ??
You can update the phone, but changind the firmware will mean that you'll lost the root.
You can update it, then you can root the phone again ....
EMUI 4.1.1
I also have TWRP custom recovery.. Would that make it riskier to update?
And how should I update? Wait for update to be available through phone or other methods? And what would be the other (easy) methods if I decide not to wait for it to be available through the settings on the phone?
If possible and not a bother, could you link another thread or a guide for this, please?
Thanks for all the help!
What build number do you have? It should be something like L09C432B383.
You can update to Nougat using TWRP but you will lose root and TWRP Recovery will go back to stock recovery. Just download the appropriate Nougat firmware that matches your Cust number (Eg, C900, C432 etc).
You can flash TWRP Recovery again and root your phone after the update.
Note: Nougat supersu.zip file is different from Marshmallows.
Build Number: L09C606B150
Ok, so should I do it directly through the phone? Or Pc?
I found an update to Nougat with the Build Number: C432B322. Should I use this one to update? And should I flash through TWRP? If yes, how should I do it?
Sorry for all the questions, I've never bricked a phone and not ready to do it now...

No you have to find a firmware that matches your cust (C606). If you flash this C432B322 you will brick your phone.

Thanks! I fortunately waited for the answer before updating hahaha
And I searched for an update with c606 and didn't find one.. how should I proceed with that?
If you really want to get to Nougat and not wait for build releases for your cust C606 then you will need to debrand your phone to C432 cust following this guide:
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
And do keep in mind doing incremental updates instead of jumps ahead of a build is better to do to avoid compatibility issues from build to build.
Hello guys! it's possible? there's a safe method to do this without restore phone or unlock bootloader?
I have VTR-L29-C636-B120 and there's no OTA updates u.u I want that B151 firmware from C432. Thanks in advance and have a nice day!.
Hi there,
Same here have also C636B120 firmware and no OTA. Any tips or advices?
Thanks
Tom
You can only rebrand your phone with TWRP. For this you need an unlocked bootloader and the unlock progress causes a factory reset.
So, without factory reset you can't rebrand your phone to C432.
If you installed a C432 firmware you can relock you bootloader, but I don't know if the OTA Updater recognize a different between locked and relocked.
You can try this. It worked for me as Updater very good, because I can't OTA update because, I rooted. But this tool has also a rebrand option. If you need any help using this, reply or send me a message.
Hi Everyone,
Ive rebranded my canadian p20pro to L29 using these guide successfully

I had some questions hopefully can be resolved.
When there is an update in firmware finder can install it directly or it has to be through twrp or erecovery?
Am i able to update magisk manager without problems?
anyone got viper4anroid working or made audio experience better for this phone?
i understand that every time I update firmware ill loose root. Is there a way to not loose it?
Will update firmware make me loose all my apps and settings?
does downgrading firmware causing bricking?
Hello!
I've done the same thing. I didn't install TWRP so I can update via OTA. Today i've got 8.1.0.131 (C432) update. If you use TWRP to update firmware it will wipe your data. Magisk can be updated without problem. Viper will not work. No support for x64 audio drivers.
Go back from l29 to l04
How do i go back to l04 from l29 i was l04 at the start
When a new update is available you can just download it and flash it through hurupdater in twrp.
After updating just flash magisk again and you will retain root (also remember to reflash twrp/have the recovery.img file in the same directory when updating through hurupdater).
You will not loose any data or settings (unless the new firmware explicitly tells otherwise).
