Can't remember my stock firmware..?

I was trying out different ROM's, and I forgot my stock firmware version. The phone is bought in Macedonia ( so it must be European, C432 ) and it is a Dual SIM. Can someone help me?
Thank you.
P.S: I'm currently on C432B160 rollback and the bootloader is still unlocked..? I need it go back to LOCKED.

Stubborn P9 Lite wont flash any firmware [help please]

So, I have a Huawei P9 Lite (VNS-L21) and I have a problem: when I boot it up I see the "Your device has failed verification..." message.
I did a hard reset (factory reset) but when I boot it up it asks me for a password and the keyboard doesn't work.
I googled around and I found a lot of posts and I tried everything, no luck.
My bigger problem is that I don't know my phone's model number and firmware version. So I cand find the proper firmware to flash.
The only thing I see is the VNS-L21 on the back. Also, I took the back of and I saw two codes (I don't know if it helps): GA20 and 160521H2
Also, (with DC Unlocker and the the phone in fastboot mode) I managed to get the IMEI and serial number. The SN is: BUC4C16519008689
Now, from many other XDA posts, I know that I have to download the update.zip archive, extract the update.app file and add it to a micro sd card in a dload folder, press vol up + vol down + power and the updte will begin.
Did that but the result was "Software install failed".
I tried to use FirmwareFinder (from Team MT) but I didn't know what firmware to use, so I used this page: https://romfirmware.com/stock-rom/huawei/huawei-p9-lite-vns-l21/
I belive (from checking my IMEI here: https://imei24.com/imei_check/Huawei/) that my custom region provider code is C432 (Europe).
So I searched on the page for a VNS-L21C432B... firmware version, but I don't know what version to choose.
I attached 4 photos so you can see what I'm talking about.
So, any ideas on what should I do next?
Thank you!

Thank you for the info. I read that post and did a little bit of searching but, as I said, the issue is that I don't know my phone's Cxxx code 100% (not sure is the European version, as far as I know it might be imported). Also I don't know at all the Bxxx code.
So what do I have to do in order to get the right one?

Funny! ) I just bought it from a friend already with this problem and I'm trying to fix it.
Update:
I read this thread: https://forum.xda-developers.com/huawei-p8/how-to/guide-how-to-unbrick-huawei-p8-failed-t3260704

Make sure, phone and FRP is unlocked. There are plenty of threads with unlocking and tools.

It's been some time since I tried to fix this phone because of some medical problems.
Now I'm resuming the work and I tries some stuff but no luck...

Please trust me, I've read a lot of "FRP unlocking" threads on XDA and I didn't solved anything.
Here: https://forum.xda-developers.com/showpost.php?p=68514977&postcount=6 I saw something that I can use Oddin, but how? And what firmware to use?...
Also other thread said that I need the bootloader code but I can't get it from the phone.
Any ideas please!?

Without unlocking code you can't unlock the phone

your bootloader is unlocked but the frp must be unlocked to , the problem is that to unlock frp must boot your device. The only rom that may fix your problem is this l21c432b370 FullOTA-MF-PV it is the PV, with this rom i unbrick my p9 lite
This rom is for L21C432B370 if your model is l31 you may brick it more or not work at all

By the "unlocking code" you mean the bootloader code? And is there any way that I can extract it or get it some other way?

My (other) problem is that I don't know for sure what exact model is because I can't access the settings. All I managed to get with DCUnlocker is this:
Code:
Found Phone : HUAWEI VNS-L21
Model : Huawei phone in fastboot mode
Firmware : NRD90M test-keys
Is this info going to help me?
If I try your l21c432b370 FullOTA-MF-PV rom can I do something that is irreversible?
Btw, you said "it is the PV". What PV means?
Thank you!

Google how to root your phone, you need imei code maybe. I can't remember anymore. And remove IMEI and S/N info, it's sensitive.

PV means point version and is used to move between android versions
If the readings are correct your rom is NRD90M test-keysand you have the l21 , so the NRD90M test-keys means that its problematic rom (it come up when upgrade from android 6 to 7 in huawei phones , if you look here you will see to many problems like your, some are lucky and fixed some are not so lucky) , what do you mean irreversible when you have a bricked phone? you can download this rom and try to install it with dload directory , i thing its the only way that you can try

Hello dear,
I don't know if the 'demo' version can be unlocked (bootloader code),
but if yes then you can use @k1ll3r8e's TOOLKIT to rebrand to another region (cust)
like C432 european or C636 asian, etc... you just need the correct files.
Once you rebranded then will be possible to upgrade to nougat via Firmware Finder app
or some other tool/script.
P.S.: What version of p9 lite do you have ? L21-L22-L23-L31-L53 ?
Cheers

Well, i think you can rebrand to the european firmware (C432);
both single and dual sim oeminfo files and matching firmwares (B160&B161) available. (see the attachments below)
But, like a told, you need to unlock the bootloader first.
P.S.: you already risked to brick the device trying by your own,
using the toolkit and doing something wrong could turn the device in a paperweight....beware what you do with your device !!!

Dear friend,
I agree with you and completely opposed to paying, but
I believe there are no other ways than giving up a couple of beers and
using DC-UNLOCKER which at the cost of 4 euro reads the bootloader code.
Obviously you only know if it's worth it and definitely remains your choice.
For everything you should / want to do there's a guide you just have to follow.
If you encounter any problems or are unsure about how to do,
you can always meet the community or me in this topic.
I wish you the best !!
Cheers

Hello,
this happened because you
choose that firmware...
you are very lucky you didn't bricked your device.
You could try to use Firmware Finder again
to revert back to your previous version,
but as i told, you could brick it,
that's your choice.
Another way is unlock the bootloader,
install a custom recovery (TWRP),
flash an OEMinfo file and your correct firmware.
It depends on the android version,
on the region (CUST) in which you live
or for which the firmware has been released
and if the device is single or dual sim.
Good luck dude !
P.S.: took a look and it seems
the link for Hassan's twrp download
is no longer available...
Maybe other twrps are still available,
but i'm pretty sure someone could
repost it for you...

At least up to my knowledge, it is impossible to get the code without a PC (more precisely, you can unlock BL without PC only if you have the unlock code).

You can try flash it with Service ROM Download . Type VNS-L31, or VNS- .
Download correct firmware - EMUI version, Cxxx (the bracketed (Cxxx) is your device’s regional variant.
This number is very important in determining the correct firmware to download. Select your previous Cxxx, not current C00 ) and single/dual SIM (all firmwares that end with even numbers are for dual SIM, odd numbers are for single SIM).
Instructions can be found in 'ReleaseDoc' folder.
If you cannot unpack downloaded zip archive on PC, unpack it in the internal memory using this RAR apk.
Extracted 'dload' folder copy/transfer to the SD card. Good luck.

Update P9 Lite from Android 6 to 7

Hello everyone, I have a P9 Lite which was issued from Vodafone Europe (originally VNS-L21C02B128), and I'd like to update it to Android 7.
Since none of the stock ROMs I tried would pass the verification when updating via the Project Menu, I found and flashed a newer Android 6 which works fine apparently - build number is currently VNS-L21C900B170.
Trouble is all of the newer ROMs are still not working. During the verification phase, it says they are not compatible with the phone.
Any ideas what is the simplest safest way to get to Android 7 ? Thanks for the help.

- Unlock the bootloader
- on android 6 rebrand to C432 global
- in TWRP install fullOTA-MF-PV VNS-L21C432B370
- then you can upgrade to a higher version by installing a Service ROM via dload method (it will lock your BL again).
The problem is probably with your current build number - the C900 is fake firmware, incomplete or incompatible. I'm afraid you won't be able to unlock the bootloader or rebrand the phone with this build.

Hello Alf, I did try VNS-L21C02B346 but it didn't work, both with the original and the newer ROM. I also tried the "SERVICE Full Repair VNS-L21 C432B381" from here, also with no luck.
The current B170 ROM was labeled as "VNS-L21C432B170" on the site I got it from, but now it shows as C900. This one updated with no problems via the Project Menu upgrade command, the only one to work so far...
I will see later about unlocking the bootloader thanks.

You can't install C432 on C02 and vice versa without changing oeminfo, that's why you now have a C900 region and failed verification.

Thanks but I don't know hot to change oeminfo. Can I use SRK Tool ?
Also is there a free way to unlock the bootloader ? Is it this one ?
Does the phone have to be dissasembled, or is there a software method as well ?
Is dc-unlocker free for phones with android 6 and 7 ?
