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.

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).

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

Take a look if there is a nougat update for your cust. If there is not you can debrand your phone with the link above.
THESE PROCEDURES MAY VOID YOUR WARRANTY!
now i know why everytime i manual update my p9 plus c636b103 to higher firmware is making it c900. its because my p9 plus is locked to its network carrier and the network smart is not releasing the ota for p9 plus. i have a vendor of smart country ph.,
pls bare to read as your knowledge/experience will help alot not only to me but to the future whom might get the same questions as mine. pls answer every questions./problems i have encountered thank you.
Q:#1 as i understand i think i need to do the debranding?? to unlock my p9 plus from my network, at first it made me so confused because my sim is unlocked i can use any sim. but then i realized its still locked in system updates from smart ph.
Q:#2 do i need to unlock bootloader install twrp and root the p9 plus first before contiunuing to the vdo of debranding?
Problem: #1, i dont fully understand the vdo of droidth in debranding the unit. i got lost of understanding in the changing of ro. build. id something like that. i tried to do the extracting the verlist but when i open the extracted verlist. img in notepad i only get random letters and symbols(ex. b&+g~), but in the video i should see vie/nxtc636b***. so i really got lost.
Problem: #2. i know i need the unlock code from huawei website.before i can unlock bootloader and i already get a code but the problem is i forgot to right it down as i only txted it to my number which i also use in my p9plus and i factory reset my p9 plus when i install back to c636b103 because if i dont factory reset after install b103 i got null imei, camera crashes, internal storage none. but after factory reset its ok.
so how am i gonna get a code again? is it still possible to get the code again? can someone pls put the link? thx.
thank you.
your reply will be much appreciated.
Yes, you need to debrand your phone and install the generic firmware for your region (for example, c432 firmwares for europe). In order to do this, you need unlocked bootloader and twrp. Root is optional, it depends on how you want to change the OEMinfo. For the unlock code I think you can ask it again to huawei in the same way you asked for it the First time. For problem#1, sorry but I have no idea what you are talking about because I didn't use that guide. Maybe try to root the phone and then edit the file directly on it with somethin like root explorer.

can i use any firmware in debranding? and should i first go back to b103? i have frimwares here b180 b190 b170 b130 b362.. all ar3 c636, what should i use? and can i do now the debranding process even if im still on c900b180?
Since you are on C900, I believe your cust is broken. Read here: https://www.google.it/amp/s/forum.xda-developers.com/p9/how-to/how-to-change-cust-c900-c432-t3392824/amp/ note: it's about p9, don't download or flash anything from there.
Now if you want you can try these steps:
1- unlock bootloader (if it's still locked)
2- install twrp
3- flash via twrp the attached file (ONLY if your phone is supposed to be L29-C636, which I believe it is)
4- install a C636 firmware with DLOAD metod
Now you should be on C636 firmware with a debranded phone.
hey, im from indonesia
i have a problem with this phone. i want to relock and upgrading my phone to the latest firmware. i have twrp installed on my phone. if i just installing the latest firmware with twrp installed, is it working? i need to upgrade it, bcz my phone being slower after a long while. thanks for your advice before and i hope you can help me
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
