How to change P9 Plus Vie-L29 change from c900b181 ? - Huawei P9 Plus Questions & Answers

Hi all, I need to change my firmware c900b181 because i can't find updates, is emui 4.1 and android 6.
I need to do this because i don't have 4G, the settings are not working correctly, and missing important stock apps.
I want to know what tool i must use and what exact firmware. I have the bootloader unlocking code for this.
Thank you

P9PLUS VIE-C900B174 help to get updates

Hi everybody, few months ago I bought this phone second hand, and since than, I didn't receive any software update. Now I was waiting Nougat, but I realized reading around, that, with the version I have now I won't get any OTA (probably the previous guy did something) Now my question is, how I can fix it? I have no idea if my phone is brand or not. Can I put a different version on it? i'm new to modding world, so I would really appreciate if somebody could help me with this, step by step. Thanks in advance!
Hello! The first thing you need to do is enter in "manufacturer mode" so you can see wich OEMINFO (zone of the phone. Could be Europe, China, LA....) you have.
You must dial in your phone * # * # 2 8 4 6 5 7 9 # * # *
· Option 3. Network Information Query and then
· Option 4. Vendor Country Info
There you will see, if your version is C900 as you explain:
Vendor: Your network provider (in my case Vodafone).
Country: All
And if you wanna have a European version (C432) you must see:
Vendor: hw
Country: eu
Once you have that info you could start with the flashing part. I'll try to help you find the wright post so you can perform it yourself without the problems that I found...

Ok. Now you must search for a Stock ROM thread that's called Stock Roms (https://forum.xda-developers.com/showpost.php?p=68105813&postcount=159) There you can see that the original stock rom that have your mobile is VIE-L09C113.
The next step it is to decide if you wanna stay with a branded ROM version or if you want to debrand it and change to one that have Nougat like C432 (Europe).
To do the debranding process you need your bootloader code (which Huawei can give you if you google it) or use SRK Tool. With SRK Tool you can debrand it with or without code. Without code I think that changes your IMEI (but im not completely sure about this).
Just search the P9 Plus forum and you will find lot of threads about debranding and updating from C900

Eva-L09C40 Wifi & BT not working + firmware to update?

Hello
As indicated in the title, I have a huawei p9 L09 cust 40, the wifi and BT are not working, I don't know if it's a hw or Fw problem, so I'm trying to update to nougat or any other firmware to find out if it's a sw problem, but I've tried too many firmwares and the flashing process fails. Current firmware build number is: EVA-L09C40B196.
1- What Firmware should I use to upgrade to any other version of Marshmallow or to nougat?
2- Can I change the cust number to get more compatible firmwares and how to do so?
I've created a huawei ID inorder to unlock my bootloader, but when I try to login using this id, the site tells me that either the id or the password is wrong, while I've used this ID in my P9 without any error! what's wrong?
Regards
I had trouble with getting bootloader code too. I got my bootloader code by emailing Huawei direct through the hiCare app. Got it within 2 days. Hope this helps.

Q:p9 plus debranding.

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.

Hi guys
I have rebrand my eva-l09 by chinese oreo firmware, using HWOTA7, and after starting up, all google service are missing, abd cannot intall it correctly, i trying all GMSInSTALL apk but nothing happen.
I tried to unlock bootloader via fastboot, a message showing up on adb command (unlock frp necessary...), can't enable OEM UNLOCK, always stay on grey.
Nothing is fine for me on this chinese firmware
Model : EVA-L09
BUILD NUMBER : System 8.0.0.046(0cs6)
EMUI VERSION : 8.0.0
ANDROID VERSION : 8.0.0
ANY SOLUTION TO INSTALL C432B504?

You say that you followed HWOTA7 instructions - did you really
1) Your screenshot shows model L09.
OP post #2 requores that you must rebrand (change location) from L09 (or L19, L29) to AL10.
You didn't rebrand, or it failed (how, why)?!
2) Your screenshot shows build number 8.0.0.046(OCS6).
Never seen any firmware like that.
HWOTA7, post #2, clearly describes that you must flash (after rebranding to AL10 c00), first b399sp17, and after b540.
Your build number is completely different?!
What you have is not result by following HWOTA7 instructions.
If you followed HWOTA7, you would have:
1) AL10 c00 b540 (not L09 b046 or what)
2) OEM/FRM would be permanently unlocked, with no OEM Loxk/Unlock option in Developers menu (not just grayed out)
3) You would have Playstore services preinstalled, you would just need to install Playstore apk
HWOTA7 OP post #3 describes how to rollback from (properly installed!!) AL10 c00 b540 Chinese Oreo back to Nougat (eg to L08 c432 b504)
But you don't have AL10 c00 b540, but instead something totally strange/wrong - I doubt that given eRecovery procedure will work for you.
You can try with HuRupdater (sorry, I never used and needed to use HuRupdater)

Sorry, really cannot help you then.
Unfortunately, since you didn't follow the guide but flashed some other firmware instead (you thought 'better' or what), you are in a specific situation, on your own, and only you should know or find how to deal with the phone and that Oreo firmware
As suggested in the previous answer, you may try with HuRupdater, but IMO, instead of further improvising (HuRupdater is very powerful but you can brick the phone), consider paying 15-20 Euros for DC-Phoenix or Ministry of solutions to safely downgrade to Nougat
After that, if you want Oreo, please follow the HWOTA7 guide carefully and in every detail (like others who now happily use the Oreo) - you will have stable Oreo AL10 c00 b540, debloated, fully working and with less battery consumption than Nougat
Also, rooted, passing SafetyNet, with fully working GApps, and ready for Open Kirin Treble custom ROMs (maybe they will work with your Oreo, too, but cannot tell you)
And if you would ever want to go back to Nougat, you would have a proven roll-back guide as in the OP post #3

Maybe I can help you...
I had the same issue just like you, even I read this post before I fix my phone.
First of all, the bootloader says the FRP-Locked, OEM Lock(or whatever says, i can't remember)-Unlocked.
On the Developer Settings the Oem Unlock option was greyed out.
Just like you.
So, reading this post [GUIDE] Debranding to C432 and updating to B361 (Nougat) for EVA-L09 i had a hunch...
What did I do to have my phone back?
1. My phone had the C432 oeminfo, so, I downloaded the dload-huawei-p9-eval09-eva-b136.zip (L09C432B136) in this post. Stock ROM dload file - P9 EVA-L09 B136
2. Copy the extracted dload folder to the external microSD card.
3. Now open the dialer app and enter *#*#2846579#*#* to open the project menu
4. Go to Software Upgrade > SDCard upgrade and confirm the update installation.
5. After the update, maybe shows an error at the final, let it be.
6. The phone restarts and boots with the L09C432B136, Android 6.0, and if you check the Developer options, the OEM unlock option is enabled. You can now lock or unlock your bootloader.
7. I need to update to the latest build and if i tried to check for an update, it says there is none.
8. I downloaded this firmware Download Huawei P9 B182 Marshmallow Update [Europe] I repeat steps 2-5, lock the bootloader, and search for an update... and update after update, I'm on L09C432B504 (Nougat)
Hope to help you...
Sorry for my bad english, I have no one to practice with...

Please Help Me!..

There are Open Kirin Treble Oreo ROMs (RR, LOS) for Huawei/Honor phones:
https://openkirin.net/user_guide/openkirin-rom-installation-instructions/
Installation instructions require:
1) OK Oreo ROMs can only be installed over Huawei stock Oreo (not over stock Nougat)
2) OK ROM must be flashed by Fastboot, not from TWRP (btw, TWRP for Huawei Oreo is different than TWRP for Nougat because of different partitions names, sizes, etc)
There is also XDA thread about Open Kirin Treble ROMs (on P9):
https://forum.xda-developers.com/p9/development/roms-openkirin-aosp-collection-t3828806

First, go back to stocl Nougat, and please read again my previous answer - I gave you link for HWOTA7 method for rebranding from stock L09/L19 to AL10 and then upgrading toAL10c00 b540 Oreo
If you don't like unlocked FRP, then go back to stock Nougat and re-lock Bootliader (and then lock FRP back).
But as long as you do rooting, installing custom ROMs, or rebranding to that AL10, you must have unlocked Bootloader and for unlocked Bootliader you must have also unlocked FRP

(Re)installing/OTA updating some stock firmwares lock back both OEM/FRP and Bootloader, but it depends on the firmware itself (Huawei who prepare them).
If you already installed latest firmware for your cust by eRecovery, you can only try to do Factory reset from stock Recovery or eRecovery
Otherwise, rolling back to Marshmallow (and after that updating again to Nougat) shoulf fix the problem with disabled OEM unlock option (I had it twice but in the opposite way, OEM was locked but its option was disabled)
However, having unlocked FRP is not a big trouble. You can still open Bootloader and root/flash, etc - problem would be if OEM option was disabled but locked - then you could not unlock Bootloader and flash anything from Fastboot
With FRP=Factory Reset Protection unlocked you (only) have:
- 'annoying' note that phone is not secure while booting
- ability to start Factory reset from Recovery and eRecovery (with licked FRP, Factory reset is only allowed once you login to the System, from Settings or Project menu)
- ability to unlock Bootloader and flash things
So, what if i wanna install Android 7 custom rom? How can i do it? Can i do it with TWRP'S special Open Kirin Edition directly from Stock Rom?
Can i upgrade my phone to Android 8 after i install Android 7 custom rom first or i have to do it with Rebrand / Update Tool first?
Because rebrand / update tool (or SRK Tool i am not sure) look so complicated and i am afraid to make hardbricked my phone... (i backed up my phone with HiSuite but i am not sure can i recover my phone with it if i unbrick my phone?)
I am using EVA-L09C464B389 rom now.... On the other hand, i cant be sure which AL10 (Oreo) rom is right for me, because when i search in russian page you offered, there is more than one alternative...
I hope i can explain what i mean with my poor English...

How do you install Noigat custom ROM? - decide which custom ROM you want to use and then find its documentation and learn there how it must be installed.
And/or, find the forum/thread about that custom ROM and read the OP posts, and ask your questions there
Which AL10 ROM you want to install...bxs on Russian forum there are alternatives? - If you want to follow XDA guide, then READ it and you will find answer there.
But if you want to follow Russian guide, then register to the Russian forum and ask your questions there
Good night and good by, I'm disconnecting from this thread and will no more read/answer - good luck
Dear @zgfg
First of all thanks for all your answers, but I am not use Russian forum same time with here. The page you advice me (in xda), and the application in there, using Russian webpage to dl stock roms... Sorry if I make you angry...
