A little confused by model/build numbers and un/locked bootloader - Huawei P9 Lite Questions & Answers

I have a SIM free ( unlocked ) P9 lite that I got from Car phone warehouse and I am wanting to update it to the latest version ie nougat. however I am confused by all the different variations ie VNS-L21C10B360 , VNS-L31C185B360, VNS-L31C636B361 etc that are floating around. My device is VNS-L31C432B131, how can i decide as to which update to use.
Also is there a way to determine if my bootloader is locked or not?
Thanks in advance.

Hello,
L31 is the 3GB of RAM version, the L21 is the 2GB of RAM one. Your device is L31, C432 means it's the european firmware and B131 is the firmware version. If you want to update tu Nougat you have to follow the L31 tutorial, and to determine your bootloader status you can do it in this way:
-Turn off the phone
-Press power button and volume up
-Your phone will boot to fastboot mode and you will see if the bootloader is LOCKED (Green) or UNLOCKED (Red)
I suppose your phone is still locked as you don't know how to verify the status

I have tried that and I only got three options.
Reboot System
Wipe data/Factory reset
Wipe Cache Partition
.

Oh sorry, you have to press power button and volume down.
I forgot that power up was to boot to recovery, I apologise!

Ive tried that and the phone just starts as normal

You can try using the computer then..
Download and install adb & fastboot minimal drivers
Allow debug USB in developer settings in the phone
Plug the phone to the computer
In the drivers folder open a CMD (shift + right click)
Type "adb devices" to see if the phone is detected
If yes then type "adb reboot bootloader"

I have downloaded and installed ADB however I only have 4 items in the Folder
adb ( exe )
AdbWinApi ( dll )
AdbWinUsbApi ( dll )
Fastboot ( exe )
There is no drivers folder

The folder with the 4 files is the correct one, open the CMD there

Thanks for helping ( and putting up with me lol ) it seems that my bootloader is locked, however FRP (?) is unlocked.

If I am correct would the revolution rom work for me on this device ( https://forum.xda-developers.com/hu...t/24-12-16-revolution-nougat-rom-rc1-t3525138 ) or would I be better with something like this ( https://forum.xda-developers.com/hu...t/android-7-emui-5-0-vns-l31-l21-l23-t3513816 ) or by using this update ( http://www.droidviews.com/update-huawei-p9-lite-manually-official-android-7-0-nougat-emui-5-0/ )

If you want to update to Nougat I suggest you to unlock the bootloader, flash Meticulus' TWRP and then follow this guide:

someone use l31c636 please creat file oeminfo help me thanks

Get Fastboot mode on Indian Model

Hey Everyone!
Its not new that there is quite some chaos regarding the fastboot mode on our device. Though some could access it, others could not. All that would happen when I tried to reboot into bootloader was that it would get stuck on the boot logo. Many said that the bootlogo itself was the fastboot mode. However lsusb on my linux term would not recognize anything attached. So I was quite sure there was some issue. Recently when I was having a chat with Nori, I could confirm that the same. It so happens that when he boots into fastboot mode, there appeared a tiny text at the left bottom of the screen would appear saying the device was in fastboot mode.
A little bit of research and experimentation, I figured out that there was an issue in the appsboot image on the Indian version. So, I flashed the Taiwan version of the aboot on my device and VOILA! I had fastboot mode! Here is how you can get it.
BEFORE I GO ANY FURTHER, I MUST WARN YOU THAT THIS IS HIGHLY RISKY IF DONE WRONG! THERE IS A RISK OF HARD BRICKING YOUR DEVICE! AND I AM NOT RESPONSIBLE FOR WHATSOEVER THAT HAPPENS TO YOUR DEVICE.
1) Head over to http://140.115.126.139:808/gplus_e7/E7_0301_v5832_IMG/ or here
2) Download the aboot.img and save it to the root of your sdcard.
3) Open up a terminal emulator or adb shell and type in the following code.
Code:
su
dd if=/sdcard/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot
4) Thats it.. Now reboot into bootloader using any rebooter or using adb and you should see something like this

P9Lite Brick?

Hi all...
I have P9 Lite. Native firmware was VNS-L31C02B125. I have debranded it to VNS-L31C432B161. All working. Today i try to rebrand my P9 Lite to VNS-L31C02B125. I have rr-inserted c02 (VODAFONE) oeminfo and cutom.bin. I put VNS-L31C02B125 UPDATE.APP in dload dir in sdcard and use 3 button metods. Update start and when arrive to 100% phone rebooted. Now there is black screen only. If i connect phone the pc i can see that it is in fastboot.
fastboot getvar vendorcountry command get me:
vendorcountry: vodafone/ro
dc-phoenix tell me this:
Found Phone : hi6250
Model : Huawei phone in fastboot mode
IMEI : 860**********036
Serial NR. : 4TE***********543
Firmware : VNS-C900B161
I have try to flash system through fast boot with
fastboot flash system C:\Users\***\Desktop\test\SYSTEM.img and other
but phone don't boot.
How i can solve? Please help me.
Your rebranding back to C02 failed...
I think your oeminfo/custom bin was not correct.
If rebranding was ok you must have firmware VNS-C02B161 not VNS-C900B161.
Most likely you flashed wrong oeminfo and custom files.
C900 build number means that.
Do you have access to some recovery (twrp)?
i can't access ti recovery. Now phone is only in fast boot mode... black screen

I think the folder you extracted the rom must be in C:\ and have no spaces or symbols, e.g. C:\miuirom and not C:\miui rom or C:\miui_rom.

Your device is in locked bootloader, you need to unlock your bootloader first before flashing ane image

Problem with recovey installation

Hello everyone, I recently installed via twrp 3.5.0.9 the new official V12.0.5.0.QFJEUXM rom from the latest xiaomi eu stable rom (xiaomi.eu_multi_HMK20MI9T_V12.1.2.0.RFJCNXM_v12-11). I just wanted to see how it was, now, I can not install the recovery again to install the xiaomi eu. Someone know how to help me.
It is as if it does not recognize the device when I send it the adb command, although in principle it does.
Thank you first of all.

Before flashing, try: fastboot devices
In Developer options, is OEM unlocking and ADB debugging enabled?
If fastboot devices does not recognize device, try another USB cable or uninstall USB drivers and try again
Yes , OEM unlocking and ADB debugging is enabled, and i had tried with original cable and other one. Thanks for your answer i will keep trying.
"Before flashing, try: fastboot devices" it doesn´t work.
Don't type reboot bootloader if you are already in fastboot
Just flash recovery.
Your address is long, try c:\adb\twrp.img

Seems that something is wrong with your USB driver on the PC - adb devices works but fastboot devices does not (where Bootloader is unlocked and OEM Unlocking enabled)
Try uninstalling the USB driver(s) on the PC or try another PC

Or copy the (twrp) img file right into the ADB folder on the PC, and go with CMD into the ADB folder before running adb/fastboot commands
Then no paths are needed, just like:
fastboot flash recovery twrp.img
But that will not help him as long as fastboot devices fails
I thought about address length, sometimes adb has problem with it, worth a try
fixed, thanks for your answers, the problem was the laptop and drivers, i have had used other pc and install without problems.
