Update to Nougat from L09-C900 - Huawei P9 Questions & Answers

Are there anyone who installed the new OS version starting from a C900 rom? I tried flasing C432B322 from C900B166 via dload method and it failed at 37%! Any tip or suggest? thx.

Can't believe nobody answered your question, i asked a simple question on here before and no reply, so i just answer other people's question instead, i too have C900B181 and have not found the C900 model for the nouget version. Any luck? I should have just updated to the C432 instead.

C900 means its a cross flashed firmware (where the oeminfo and the firmware does not match). I also believe that C900 does not get updates or is the last firmware to get updates.
P.S. People on XDA usually dont answer simple questions that can be found by searching Google or has been mentioned a number of times in the forums and yes, information about C900 has been mentioned a number of times in the P9 forum.

How would i be able to downgrade to C432 from C900 becuase I'm sure you are right that i wont get any OTA update on C900.

As mentioned, C900 is a cross-flash version. Your only options are to roll back to the previous/original firmware, or to follow one of the guides to de-brand (which includes steps to match your oeminfo partition to the firmware).

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).

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.

Move from c900 to c432

Hello my cell phone, has the C900 compilation and has android 6, I would like to know how to go to the C432 compilation?
Thaks!
I have C900 too. There's a way to change I think but the C432 updates, if you download them and install manually, are compatible. It's how I've been updating my phone ever since I bought it. I have installed B380 update currently. There's a newer one but some folks are having trouble with it so I haven't updated yet.

Update EVA-L09C900B182

I have a Huawei P9 that doesn't seem to receive updates.
EMUI 4.1.1
Build: EVA-L09C900B182
Andriod: 6.0
I have tried using firmware finder but I always get checksum failed before it passes 1%.
I had a look through the Forums and it seems that people recommend rebranding though that was in 2017.
I was wondering if there is any easy way to update?
I am a noob so i want to try avoid rooting and rebranding if possible.
Has anyone managed to update this?
2 years later and I'm still trying...

For c900 there is no newer firmware.
Flashing anything else than c900 means rebranding - but rebranding requires unlocking Bootloader (not 'rooting')
So wandering, what are you really trying to do for two years?!
- Unlock Bootloader (4 Euros):

- Rebrand properly to be able to update to Nougat eg EVA-L09c432b504:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
I followed that guide but now my phone is stuck on "Type the password to decrypt storage" when I enter my Google password it says it's correct but data on my phone is corrupted. Any ideas?

Are you talking about TWRP asking for pass or Android?
If Android, on which firmware are you, what was the last step you performed?
Also, make sure you used TWRP for MM, not for Nougat - since you were on c900 MM when you started with rebranding to c432 (?)
Btw, you unlocked the Bootloader?
Thanks for the quick response and all your assistance. I managed to finally boot into EVA-L09C432B182 and will write what I did in the rebranding post for others who run into this issue. I still have no updates on L09C432B182 though.

For OTA you must have a valid SIM card and WiFi - check manually to the System Update to trigger checking for an update
You can also try with HiSuite (PC) - latest versions of HiSuite have an option at the bottom to update the firmware
See:
https://huaweiflash.com/how-to-flash-huawei-stock-firmware-all-methods/
You can also update by DLOAD (read the guide above), you must download FullOTA-MF-PV (must be PV), like b360, from Firmware Finder
There is also HWOTA method, see:

I don't know have you really been originally on that cust c451, or you rebranded to c451 as part of going back to stock / rolling back to MM
Anyway, c451 is a dead end, check on FirmwarFinder or at:
https://pro-teammt.ru/firmware-database/?firmware_model=EVA-L09c451
you will see that EMUI 4.1, b131/b132 are the last ever firmwares for c451
You need to rebrand to some 'proper' cust like c432 (European), c636, or so, to be able to obtain OTA updates up to EMUI 5, like it was described here:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
Rebranding to c432 is crucial. If updating to b182 as described there will fail, you should be able to reinstall c432 b182 (or newer c432) by eRecovery, or by flashing service restore c432b182 (but there are no service restores for c451 and no Nougat firmwares for c451)

Thanks for the reply,
No, ive been originally on c451. I dindt change anything on this device. I bought it at amazon almost 3 years ago, and apparently it was a "telstra" phone, i think from Australia, altought in amazon it said unlocked. Now im using Movistar network in Argentina.
Ok then, the question is, is there any way to know that after rebranding to c432 or another cust my device will work properly? i mean phone signal (the most important thing), camera, fingerprint sensor, etc.

Hardware is always the same, rebranding puts the other cust.
And with cust c432 you should receive OTA updates up to b504/b505
If not, for some reason (then it is possible to force DLOAD or HWOTA updates
Btw, responding you now from L09c432 rebranded to AL10c00 (Chinese), with Oreo b540 (Oreo was released for P9 only in China) and with some adaptations (Chinese firmwares are specific), everything works ok.
If you search throughout XDA, you will find many users (for all kinds of Huawei models) rebrand here and there, usually to c432 or c636 since they obtain faster and more updates (except for Chinese AL10, AL00, DL10 and alike that get first and farthest OTA updates, but Chinese firmwares require adaptations to become useful worldwide: bloatware, missing GApps, missing intl languages and configurations for intl carriers, and so)
Btw, didn't you previously say that you returned to stock (from custom ROM?) - in that case you must have Bootloader code (for rebranding you need to start with the unlocked Bootloader - have also OEM/FRP unlocked)
Edit: Btw, this is a wrong thread for discussing the update of stock MM firmware to Nougat
