I've been on fRomFuture B171 for a while now, and I'd like to rollback to stock Nougat (or update to Oreo/Pie), but I can't seem to find any official firmwares.
All the links I can find are dead or 404'd. Same goes for the links on xda threads that I've been sifting through.
I'm running VTR-L29 (rebranded, VTR-L09 originally) with an unlocked bootloader and TWRP.
Using eRecovery to recover over WiFi yielded the error that the package info could not be found. Any suggestions?
Thanks in advance, I appreciate your help!

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.

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).
Wondering whether anybody's found success in flashing the EVA-L09C02B340 firmware via dload?
It didn't seem to work for B339 but hoping for the best with this one.
Thanks for any helpful replies
Edit: Just tried flashing via dload but installation failed (oh well)
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.
I'm on L09C09B361 (unlocked bootloader). I've went back to stock recovery and I'm trying to flash update_data_full_p4_pl.zip via dload; it flashes in few seconds (goes from 5% to 99% and it's done), but I still don't have the apps.
How do I reflash the stock ROM (I have both update.zip and update_data.zip).
Thanks.
Anyone? :/
I have tried Huawei Updater 2.0 and Firmware Finder DNS, doesn't work.
Locked bootloader, unlocked bootloader - doesn't matter.
HiSuite complains about internet connection when using any of these.
Hello,
A few days ago I managed to change the rom on my Huawei P9 from c150b367 (Telekom Hungary) to c432b386 (general European). I could find the oeminfoc432.zip on the internet.
If I wanted to go back to c150 (telekom), where can I fownload the oeminfo c150.zip file from?
Thanks in advance for your help.
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:
