Debranding EVA - L09C900B191 - Help - Huawei P9 Questions & Answers

Hi there,
i'm trying to debrand a P9 EVA L-09 using the methods shown by Zblade in (https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523) without any luck.
Using the stock recovery, i'm trying to "force" flash the C432 without sucess. It always gives "failed" , even using the dload folder and update.app rename.
My network is unlocked, but accessing the vendor menu ( * # * # 2 8 4 6 5 7 9 # * # * and going to point 3. Network Information Query and Push point 4. Vendor Country Info) it has the provider that sold me the device.
Can anyone help me in this subject? Is there a way to debranding it to a european firmware (mine's from Portugal) compatible with my EVA-L09 ?
Thank you in advance!

That guide is somewhat old, instead of rolling back to c900b136 you can rollback to c900b300 and from there to go to c432 b182
But be aware of unlocking Bootloader (as in the guide, and how to do it) - it has nothing with locked or unlocked network

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

Device Won't Boot After "Device Is Now Booting" Screen

Hello,
I have just unlocked my HuaWei P9 and installed TWRP 3.0.0-0 on it.
The device was refusing to install SuperSU as it kept saying the zip was corrupt, even though it definitely wasn't. (I even tried multiple different ones)
Then I saw a tutorial that said this can be fixed by going into the Wipe menu, Advanced Wipe, selecting Data and changing the file system to EXT4. I did that (even though it was already on EXT4) and now my device won't boot past the "your device has been unlocked and can't be trusted. To learn more, visit: (link)
Your device is booting now...." screen.
Please may anybody help me? I can access the recovery menu and the TWRP menu, but not the actual android os. In the TWRP file viewer, the device is not blank so I know that the device has not been erased.
Thank you very much! I am not bothered about rooting anymore, I would just like my device to work. Any help will be very much appreciated.
Download a custom ROM flash it via twrp (if you di have twrp previlages ) or download official firmware with same cust as your then put in your microsd>dload(folder)>update.app

Mine is an EVA-L09 and it was running Anrdoid 6.0.0. That is all I know as I have not had it for long. If there is any other information you need, please may you tell me how I can find that out?

I have all of the original packaging, is there any way to find out more information about my device through that?
EDIT: I have managed to find out the IMEI, if that is of any use.
Did you take note of your current ROM version that is on the phone? It should be named like this for example.
L09C432B136
L09C is the model no of the phone e.g EVA-L09C.
C432 is the CUST (Also for OEMinfo)
B136 is the build number of the ROM.
Did you flash any roms or are you still using the original ROM that came with the phone? Also do you remember if you were on marshmallow or nougat?

I did not note any information as I wasn't expecting to have any issues, I've rooted a few phones before and have never encountered any issues.
I managed to fix the issue by using the above method with both volume buttons and the power button - I downloaded "dload-huawei-p9-eval09-eva-b136.zip" and installed that ROM, which was successful
Thank you so much for your help.
No worries. That is usually a failsafe version in case anything goes wrong. Network for 3g/4g is working I hope and build number is displayed fully in settings right?
As different CUST ID from ROM can cause many issues.

I will have to look into what when I place my SIM into my phone as I am waiting for a carrier unlock code.
At the moment, the only issue is my homescreen wallpaper showing up as my lockscreen one, which I created a thread for.
Is there any way to check the original cust id?

You can't rebrand (but you could brick) just by flashing c432 build.
Maybe you can do it by HWOTA7 (advantage, no need to go back to MM), similarly as explained in posts #1 and #2 (you can directly ask in the thread would it work, maybe you can escape c432 ang go directly to AL10b399 etc)
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
But for sure you can rebrand to c432 by rolling back to MM (and then you will receive OTA updates for c432 for Nougat)

Hi
Sorry for my late answer. HWOTA7 is primarily for rebranding on Android 7 without having to downgrade to Android 6.
A) Just read first Post 1: https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849/
B) Follow the Guide from Post 2 - STEPS 0-10 (11 and 12 are only required, if something went wrong in step 10) - but in Step 8 you must choose the oeminfo for your needs (in your case L09c432) and of course, you must have the Firmware for the new oeminfo in the update folder!
https://forum.xda-developers.com/showpost.php?p=77161313&postcount=2
I would recommend to use b504 for EVA-L09c432 for now, because it is currently approved

The last two zip files must be renamed! (Further instructions in Post 1...)
Wish you success

No, it doesn't contain any personal information on Android 7 and Android 6 - only on new devices with Android 8 oeminfo include IMEI.
That's why it's not possible on Android 8 to change location by changing oeminfo...
@miksly Would you please zip your oeminfo Backup and upload it for me (I would integrate into HWOTA7) , thanks

can't unlock bootloader or frp

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...

Hi! I don't know which version it's fine for your device and the only way to know it it's to flash it yourself, but i don't recommend you to do that.
Rooting with Magisk is fine on 9.1, just read the latest posts from this thread - > https://forum.xda-developers.com/mate-10/how-to/guide-magisk-root-mate-10-pro-t3886967/page27
As for the roll-back, ut should be possible to do it with this tool and an appropriate roll-back firmware (again, firmware version might depend on your cust/brand).
I recommend you to keep an eye and also read this thread - > https://forum.xda-developers.com/mate-10/how-to/firmware-version-mate-10-t3722019

B303 is not for A09, it's for C800 which is some jp cust.
Most new fw links are not up yet, and since Huawei decided to name all their firmware the same regardless of model its hard to know which is which :/
Success! Updated BLA-L29C432. Thank you!

Great! Soon i will upload a new version that will also flash the patched Magisk ramdisk_recovery and Magisk Manager (this one will be optional, so those who already have it, can skip it).
It worked for me also.
Why is root needed? Unlocked bootloader is not enough?

Nope! Well, it can be done without root too, but it would require twrp in that case.

Somewhere on Huawei's servers! xD

as stated before, since every update is named the same it's hard to tell which is L09, L29, A09 or AL/TL. AL/TL are easier as VERSION.mbn in UPDATE.zip doesn't have Global strings in it.
From what it seems, if you flash L09 on L29 or vice versa you get endless OTA updates for preload and cust. I don't know if just flashing the cust and preload zips fixes it, but you're free to try if you want.
Here's L09 preload and cust:
Preload: http://update.hicloud.com:8180/TDS/...full/update_full_preload_BLA-L09_hw_eu_R1.zip
Cust: http://update.hicloud.com:8180/TDS/...4//f1/full/update_full_cust_BLA-L09_hw_eu.zip
modified tool to include preload and cust:
https://mega.nz/#!oDR2DYCI!SRQlTq1IriGcEt1Wr--ggrBk7uZ4M_R8OwE6DdvmEEc
Extract and put in the EMUI 9.0 to 9.1 update folder.
Rename cust zip to update_cust.zip and preload to update_preload.zip, put in ZIPS-HERE folder, run modified bat.
Thank you very much, I try very soon. Have any of you done that already?

I did on L29 with L29 preload and cust, no problems.
Base (280955) seem to be the same for both L09 and L29 C432.

Soon i will upload a new tool that will let you flash all the 3 files, so you could wait. Also, a fried of mine is testing on BLA-L09 C432.
Perfect, also because I don't have the Root permissions on the device, and I don't even have twrp. In fact now I have tried and says that it does not find root permissions. Then I did not understand if the phone should be connected from on, in recovery or fastboot?

Tool updated. However, if you don't have root, you can't use it, you must root first.
Okay, I thought it was a tool like the ones we made earlier to install EMUI 9. I'll wait until the new tool is released. : D
