Yesterday I figured to debrand my VNS-l21. Everything is fine, updated manualy to latest ROM B130. But, CUSTC has changed from C02 (Vodafone EU) to C900 (Global). In P7 thread there someone posted small update.app file (around 18 kb, http://forum.xda-developers.com/ascend-p7/help/p7-l10-defect-report-reminders-t2952124) that after flashing will change the CUSTC back to C432 (EU open market).
Have someone idea where to get this file for VNS-l21?

Nice work with the toolkit Years before I had unlocked & rooted every of my smartphones but, last two years I need to work with some apps that recognizing rooted device and won't work (bank app etc.). So if there no chance to change the region back to C432 without rooting the device, I will stay on that Global CUSTC (after two days of deep testing, there's no problem with it). Maybe later someone will do that update.app file or will be included in future update ROM.

-
About the build id, the only problem which happened to me while i was on the Asia build is, that u don't get any updates...
About the update.app, i just downloaded the file u linked me, i'll have today a look at it. Maybe we can produce such an file also for our L21/L31.

First, if you can build that update.app for l21/l31, it would be amazing, because that will be BIG help for everyone who want only to debrand our P9 Lite's without lose warranty or brick it.
Second, nice to have there someone, who taking care of this phone :good:
Hello dear developers...Recently I bought a used Huawei p9 lite vns-l21c150b106 single sim...It is cosmote branded and I want to debrand it cause I found out by searching that there are several updates such as b150...When I try to update my phone it says that has the latest updates...I wanted to ask if there is a way to debrand it and return to official Europe stock rom without void my warranty...I found a way in the internet through local update via sd card but I don't find the stock rom Europe(I live in Greece)for my single sim vns-l21...I found only vns-l21c432b160 which is for dual sim...I think that vns-l21c150b160 must be for my single device,i suppose that the difference is c150 and c432...any solution please???
Hello everyone!
I just bought an used P9 (EVA-L19) in pristine condition. It arrived with the nougat update but it is missing all Huawei apps. I don't think I really mind not having those (less bloat, hurray!), but I really want at least the camera app! What should I try? This thing is full stock (unrooted), and I'd rather keep it that way... Should I just flash the full stock firmware? HiSuite claims my phone is up to date, but I've got no idea how to check what build my current firmware is.
Thanks!
Oooh... the build seems to be NRD90M "test-keys", which appears to be an old beta build from my googling. Do I have to go back to MM and then upgrade to Nougat? Hopefully I can do all that without a custom recovery...
You have an intermediate firmware.
Search here the B378 for C432 if you want the european version (wich is working fine; some other last updates may have some problems - for example, with B383 me and others have problems with the battery).
Where are you from ??

I'm from Brazil, but I know for a fact this phone isn't brazilian. It comes with a bunch of stuff written in spanish rather than portuguese, and a warranty certificate citing a bunch of spanish-spekaing latin american countries. I'm browsing through the forums and trying to find out what is my Cust yet. But thanks for the response.
Also, if I have to flash something, is it better to stick with Nougat or is Marshmallow more hassle-free?
(I've attached a screenshot of the status screen from Huawei P9 Tool, this is all the data I could gather so far)
I can't read the screenshot ...
On the "About the phone - Version number" what do you have ??
For example, mine has EVA-L19C432B378, where:
-EVA-L19 is the phone model (P9 dual sim);
-C432 is the european version;
-B378 is the firmware version.
Also, you can read that thread too ... https://forum.xda-developers.com/p9/how-to/how-to-downgrade-nrd90m-to-marshmallow-t3541400

All it says on "Version number" is "NRD90M test-keys". I've read that thread, but to downgrade you need a ROM, and without knowing my Cust ID I'm not sure which ROM I should get.
The screenshot shows my serial number (XVV7N16425001010), the model (EVA-L19 - Dual Sim 32GB Rom 3GB RAM) and a weird build string (eng.jenkin.20161230.130431)

Hello,
do you have dual sim , or single sim and NFC ?
Dual sim: EVA-L19 ou L29
Single sim and NFC EVA-L09 (Européan version)

Dual SIM EVA-L19 - No idea if I've got NFC or not. Can't find anything NFC-related on the menus, but it might be that I do not know where to look. Long time Windows Phone user here, just migrated back to Android :laugh:

NFC is an connectivity option.
If you don't have, you have dual sim

It does have dual SIM, and is the EVA-L19. So no NFC then. Does it help? I'm currently looking for debranding guides because I can't find what branding this phone originally had.
Oooh well... so far:
1- *#*#2846579#*#* doesn't work (nothing happens), can't enable Manufacturer mode for DC Unlocker
2- The HUAWEI EMUI site doesn't give me a bootloader unlock code, so can't unlock the bootloader with the official method
So, so far, I can't install TWRP, so I can't flash a C432 oeminfo.bin
Also, the Rollback instructions at https://forum.xda-developers.com/p9/how-to/rollback-eva-l19-android-7-0-emui-5-0-t3496091 fail, as the rollback intermediate firmware just fails at 5% claiming to be incompatible with my device.
Aside from blindly trying to flash random firmwares with the three button method, do you guys have ANY ideas at all? I need a rest, just wasted the whole day trying to get this damned thing fixed
Sad thing: even with a borked firmware install this is still orders of magnitude better than my old Lumia 930.
EDIT: GODDAMMIT, BLUETOOTH ALSO DOESN'T WORK!

I'll give the instructions of the first post a try, though they did not work for the OP.
EDIT: AAAAAND the 800mb file is downloading at 28kbps... this won't be fun
I'm not sure if it would've been better to edit the last post or add a new one, so if this is agains the rules (I've read them and couldn't find it), please inform me and I'll change things accordingly... buuuut.... IT WORKED.
The OP on the topic absynte pointed out never really posted the outcome of his issue and it looked like he never got it to work, so here is what I did:
Flashed the zip file
I flashed the zip file linked in this post through starting up with vol up + vol down + power. Exactly like the guy over there it did not solve my issue, but did uncover I had exactly the same build as him (EVA-L19C185B361 - Middle East / Asia)
Flashed the intermediate firmware
I download the correct intermediate firmware (C185B300) from here and flashed the same way. The *#*#... menu did not work (as in the menu itself didn't show up)
Flashed a MM build
I downloaded and flashed C185B180 for whatever reason (could've gone with tha latest MM build right away AFAIK). Worked great, all stock apps were there and so was bluetooth
Let the phone update itself through OTA
It updated itself to B210 (or B220, don't remember well) and then B385. Seems to be working fine, but I haven't given the battery a fair chance (constantly flashing and updating stuff) to judge its performance.
Thanks everyone for the help!

Hello guys,
I have failed. And now I do not know how to continue.
My tragic storry: I wanted to update my HUAWEI P9 from Marshmallow to Nougat and got an error during update, because I am an idiot. I took an (wrong) update from some site, putted it in a dload folder on a sd card and started the update. The update started, the phone rebooted and continued. But at 5% comes "Software update failed! Incompatibulity with current version. Please download the correct update package."
After that I started to search for a solution.
Now I found this site and it seems that here are a lot of people, that are able to solve such problems between wakeup and teeth brushing. I hope someone here can help me with good advices, which avoid me of damaging my phone completely and bring me instead on the way that I can solve my problem.
Enough of the chatter, this is my current knowledge (correct me if I am wrong):
I have (had) a P9 with EVA-L19C636B190 Firmware. (I have noted this before update)
L19 stands for the dual sim P9.
C636 is the Asia/Pacific Hardware
B190 was the old version of stock Android (Marshmallow)
(I know now, that I have tooked the wrong Hardware-Package. I should have taken C636 and
everything would have become beautiful)
As I understand, the wrong Firmware is now on my phone and the bootloader try to continue the update each time I start an Update.
If I start the phone normaly, I get the EMUI logo with the options to "Download latest version and recovery" (No way, with the wifi connection, he can not find a server to download), "Reboot" and "Shutdown".
I suppose, that there is a partition on my phone, where the wrong update file was loaded to. Because if I try to "update" back to EVA-L19C636B190, there is no difference, the update ends at 5%, even without a sd card. So I think, that I need to clear this partition and need to start an update with the dload-folder-method again.
As I understand some artikles here, I need for that a special tool (SRK), with which I can clear the partition in the FASTBOOT&RESCUE MODE. But for that the phone must be unlocked.
In next step I need to unlock the boatloader with the huawei online tool where i get the unlock code based on my serial number and so on.
What would you say to my plan? Or is there an easier method?
What do I need for that?
Please be indulgent with me, I try to learn and to undestand to solve my problem
Thank you in advance.
i make rebrand to my p20 pro clt-09 to clt-29 c432 but after install i have new strange version !! its clt-l29 chipset-boston 8.1.0.001 ( 01FL) !! so what is this
Have you copied and edited oeminfo.bin via adb?
i also got the same problem. also my phone is unrecognized from PC......if i want to transfer file to pc i need to rebbot into twrp, then PC will recognize my phone again...dont know if this problem is related
is there any way to solve this..i already flash vendor.img using fastboot but cannot flash verlist.img (if the build number is in verlist.img)
i read the forum say that flash version.img will correct this problem....but in our FW there is no version.img
https://forum.xda-developers.com/showpost.php?p=76473957&postcount=1
Follow the steps for rebranding (especially part with oeminfo).
If you have root access You can also download oeminfo from link directly to your phone and follow edit commands for edit via some terminal app directly on phone since you don't have adb connection.
I also got this strange build name after I tried to rebrand my P20 Pro from CLT-L09 8.0.0.110(C782) to CLT-L29(C432) using FunkyHuawei
I'm not sure what are the implications. Which region is 01FL? It seems to be stuck on the very first version (8.1.0.001) and no update is available
What should I do?
I have same problem after rebranding Clt-L04 to Clt-l29, I have chipset-boston 8.1.0.001 (0193), I want to know what 0193 ?, is that we can do update
Ok I think I can help because I reversed this issue like 5 minutes ago. Take note, my device is a CLT-L09. I flashed a file for the CLT-L29 instead and caused myself problems.
You need the huawei firmware finder app
Once you have that app installed, put in your model number and download the files for your model. You need the public, hw and update.zip files (You will see those words in the 3 files, I believe in you, you can do this)
Flash these files with HurUpdater. See here and follow instructions: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
If you did this right you should see the correct model and software info in About Phone
Let me know if this wasn't clear enough
So I'm also getting the chipset-boston model problem, can anyone elborate a bit more on how to fix this? I've gone thru the steps 3 times and no change. Any further software installs fail at 5%. The first one went through no problem.
Can you give any more info so that I can try help? What model is your phone etc? What files did you download and flash?
I solved it by rooting and deleting the oeminfo folder in data/local/tmp directory and then copying the oeminfo file to data/local/tmp. All commands then ran without error.
~ Just wondering,, I have a CLT-L09(C782) Huawei P20 Pro in UK and I did the *# dial and it said my chipset-boston 8.1.001 is this normal.....
I have no root,, not even attempted,, only official software from Huawei OTA updates thats all... I wouldn't root as on contract..
Hello everyone !
I had a battery drain issue so I wanted to try and change the software before resorting to a battery change, but now my phone is stuck at L09 C900B300 build and it used to be factory L09C432B504. I tried downloading the full package for 501 but the phone does not want to install it as it was "invalid".
Any ideas how I can force the b501 update on the phone ? It's hard to use ADB since the USB-C port on the phone is very worn out and it only maintains data-transfer in a certain position, if it gets shifted even a little bit it breaks the connection.
Thanks in advance !

You did a rollback and you cannot instal Nougat directly back
You must install c432b182 Marshmallow and then let it update by OTAs (with SIM card) to b50x
https://forum.xda-developers.com/showpost.php?p=73131443&postcount=321
Steps 4-9 apply to you (since you are already on c900b300)

Don't know what does it mean to you that you changed the software
If you rebranded from c432 to another cust, then you must also rebrand back to c432 by flashing its OEMINFO:

NOTE: Just saw you previously asked questions about P9 Lite
Pls be aware, this is Huawei P9 subforum, not for P9 Lite (different hardware, different firmwares)
The answer above with links/guides applies to P9, not to P9 Lite
If your question was for P9 Lite, please better search and ask on XDA P9 Lite subforum
Hey !
Thanks for your reply.
I have tried to follow the steps but I need to have the bootloader unlocked and it is discontinued by huawei, and in order to get the code from DC unlocker I need to invest a certain amount of money (id rather hand the phone over to a professional service and pay them and know that I have a fixed phone).
The other issue of the phone is that I cannot open the manufacturer mode on the phone using *#*#2846579#*#* since it does nothing, and I cannot use the calculator since this software does not have a calculator, it doesn't even have a camera app....
So I have contacted huawei support in hopes of getting the bootloader code but I do not hope for too much at this point. What are my other options at this point of handling this on my own ?
Looking forward to your response !

AFAIK, 'certain amount of money' for Bootloader code from DC Unlocker is only 4 Euros
If you search on XDA (various phones, just about Bootloader unlocking) you may find more online services (several months ago I've seen in some post), but they were more expensive
IMO, you don't need unlocked Bootloader if you are just following the first link, for dload-ing c432b182 without flashing oeminfo....
Update:
Okay the b182 package does not require unlocked bootloader which is great, it took the update and started going up all the way to b395 but it stopped there, no further OTA updates... It is okay to use at this point but I'm still curious to know if there is a way to get to it to update to the b50x version. I did try to use the small update for the b501 but the phone declined it.
Still thank you very much for guiding me through this ! This is a huge weight off my shoulders !

In Firmware Finder they have a new method based on eRecovery and changing the DNS server on your local WLAN AP
b50x must be showing as Approved to you for that method
It does not require Bootloader unlocked but no guarantee it would work (I tried with P9 rebranded to AL10 Oreo, managed to change DNS server address, eRecovery connected to but failed to update firmware that way)
There HWOTA method (in few variants) to install FullOTA-MF from Firmware Finder, but unlocked Bootloader is required
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
Btw, if you ever unlocked Bootloader on that phone, just use the same code again (one must save always save the code for future needs)
As of recently there are some Huawei service firmware installations available, that also install by dload (not needed to have Bootloader unlocked)

When you download, you will need to unzip
Find Docs and Software subfolders (you may need to untar and unzip Software subfolder again)
In Docs folder there must be Huawei official guide how to install, check if it describes dload method (and what must be un-archived and copied to SD card dload folder from the Software subfloder)
I didn't use it for L09c432 but I successfully unbricked a P9 rebranded to AL10c00 (back to AL10c00 firmware) by such a package, really easy by dload, just by following their HowTo doc from the Docs subfolder
