Hey guys!
I've installed the Nougat beta for my P9 Lite VNS-L21 Dual Sim, but now I want to downgrade to MM. This is what I did:
0. Installed Nougat via Melticulus TWRP
1. Installed Revolution Recovery (because Melticulus TWRP had stopped working, idk why)
2. Flashed OEMInfo
3. Copied Version B150/B151 (I've tried both) to the SDCard
4. Started the P9 Lite with Power + Volume UP + Volume DOWN and tried to flash one of the versions.
I'm stuck here, the Huawei Recovery says the following: "Software install failed! Incompatibility with current version. Please download the correct update package!"
I've used HTC Mania, Thread NR 1200630 to download the stock rom for my P9 Lite, I've tried both the VNS-L21C432B151 Android 6.0 EMUI 4.1.1 Europa and the VNS-L21C432B150 Android 6.0 EMUI 4.1.1 Europa

Back up your data
- Unlock your bootloader
- Flash TWRP
- Root
- Use SRK Tool to change your Oem and cust files to the same version of the rom you want to install
- install your rom same version than oem and cust with TWRP
- Let boot completly
- Factory reset
- Then relock your bootloader with fastboot
It will factory reset again and you'll have a full official working device.
It should work just great. There are some tutorials on the forum just look at it.
Try the step by step guide in this link : https://forum.xda-developers.com/mate-8/general/how-to-install-nxt-l09c432b560-official-t3542546

i was on NXT-L29C636B321 and i never rooted or flashed something else on my mate. (i only upgraded with dload method a few months ago)
For what i remember i did like that:
-Unlocked bootloader with dc unlocker and SRKtools.
-installed twrp with SRKTOOLS
- rooted with SRKtools or flashing with twrp i can't remember.
- backup oem and cust and then change it from c636 to C432 with srktools.
- factory reset
- relocked bootloader
then i've done the step by step guide of the B560 official from the beginning.
Everything works great. dual sim, mms etc...

Did you change your phone's cust version? If u changed it you should dload a firmware (4/4.1) that match with your new cust
I rolled back with this method dozen times when EMUI 5 was not officiall!

Is that red message verification failed message?
If yes then please unlock the bootloader again even if it says unlocked. Then it will do factory reset and the red message will disappear.
You can then try to flash the stock firmware in TWRP. You can use B368 or B386 stock firmware from another thread and flash in TWRP. That is if you have TWRP. If you don't then unlock bootloader and then install TWRP using SRK tools. You can use SRK tools for adb commands also. Just type 000 on first page off srk tools and you will get into command prompt. Using that push the TWRP into your phone. ADB is very stable in srk tools and it will always identify your device. So that problem you won't have.
I couldn't find a proper rollback for AL10 . May be some one else can give if it is there for this model. If it was L29 model then rollback package is available and you can easily rollback using that in this type of situation.
If the flashing of stock ROM worked then you try to debrand your phone to L29 later. You will have many options then and L29 firmwares are more stable. I have AL10 which I debranded to L29 & I totally recommend debranding to C432 once your problem is solved
Do the above steps only if you are on marshmallow firmware.
Don't forget :good::good::good::good::good:
I created a al10 roll back for all al10 phones. It converts it to a DL0017 dual active sim. Message me for details how to obtain it from me .. MUST have twrp installed .

If you want to unlock bootloader through ADB?
Here are the steps.
In your phone go to settings - >developer options - > put usb debubbing ON
switch off the phone.
Press and hold the down button for 3 seconds & then connect it to the computer
It will then go to fastboot mode.
then open SRK tools
type 000 to enter the command prompt.
Type the following command
fastboot oem unlock xxxxxxxxxxxxx
In this command xxxxxxxx is your bootloader code. just replace xxxxxxx with your code and press enter.
This will unlock your bootloader & will do a factory reset.
In SRK tools there is an option for bootloader unlock but I think that is only if you are in EMUI 4.0 or EMUI 4.1 that is what I think may be anyone else who tried this option in android 7.0 can confirm but the adb commands will work.
I have enclosed screenshots for better understanding.
you have mentioned that you are in Android 7.0
Can you tell me your exact firmware that you have on your phone at the moment?
After you get rid of that red message. Your bootloader is unlocked.
There is Erecovery process - > steps below (but there is a problem with this process)
1)Switch off the phone.
2) Press and hold the volume up button and then connect your phone to computer or charger. Yes charger. Then you can download stock firmware through your WIFI - > this will also install stock firmware. But I think this won't work because of unlocked bootloader
So once again install the TWRP for Android 7.0 I think it is Twrp 3.0.2 or Twrp 3.0.3 - > this is definitely for nougat.
ADB command to install twrp recovery is
fastboot flash recovery twrp.img ( rename the TWRP to twrp.img ) in the adb.
Try to flash the stock firmware zip files in TWRP.
Here you have two options - > You can either try flashing B386 files (only one zip file) or B562 (android 7.0 - > 2 zip files - first update.zip and then the other zip file)
If you are successful in this step then your TWRP will be overwritten with stock recovery.
That is ok. don't worry. Kangvip ROM is pre-rooted ROM. So you will get root in the end. For now its ok to be on Stock at this step.
Stock Recovery + Stock ROM + bootloader locked -> then you can dload back to EMU 4.1 using B386 firmware.
Then you can unlock bootloader (again) yes its a pain + followed by TWRP + ROOT - one after the other in SRK tools its all there. you can use the options in SRK tools this time.
And once you have root again.
Take backup and save it on your SD card. (except DATA , take backup of all options listed there, why? bcoz if you include data - > it will increase the backup size and it will take more time.
*Disclaimer* -> Very tricky & risky process - proceed with caution & full attention
Then - > you can debrand - > to C432 -(debranding is very tricky process, so keep your backup handy) This should be done very carefully because any problem here means you might find less space on your internal memory. Then you will have to restore that backup to get back your space.
Here is the link to excellent tutorial by somboons Watch it carefully.
https://www.youtube.com/watch?v=JZVsIKtdgV4
Just follow that as it is for debranding from AL10 to L29-C432
I am very very sorry for all these confusing and tricky steps. Please proceed with caution when you are doing the debranding process. Do not get diverted during that process.
Yes I did all this when I debranded my Huawei Mate 8 AL10 to L29. I had lot of anxious moments, doubts & my mind started playing tricks if mate 8 was dead on few occassions. But in the end my phone prevailed. Now I am happily using L29 - Kangvip B577. That is where I want you to land up in the end.
Do not worry and do not panic any time. Be prepared to face few challenges during this process. I will help you but please share your experience and follow the steps carefully.
During debranding you might have your phone rebooting or something might happen. That time do factory reset and continue from where you left off. If you get red message - > then you have to unlock bootloader. Otherwise continue.
This whole process will test your patience & consume time. So I hope you are willing to do this. Its worth it. I learnt my lesson, I am never buying chinese version of Huawei phones/tablets again. Only European models from now onwards.

TWRP 3.1.0.2 is actually used for flashing nougat firmwares.
Which firmware are you on right now?
Are you on nougat or marshmallow? Please provide the full firmware build number.
if your phone is on marshmallow.
TWRP version depends on your firmware.
If you are on EMUI 4.0/4.1 then pls use the TWRP 3.0.2
you can use SRK tools to install that TWRP if you are on EMUI 4.0/EMUI 4.1
Install that version. Then
Factory reset
Flash the B386 zip file in TWRP.
You can get the B386 from here https://forum.xda-developers.com/showpost.php?p=69331930&postcount=1338
If your phone is on Android Nougat.
Then you have to use dload method.
Unzip the B386 zip file.
Put the update.app in the dload folder inside your external sdcard.
Go to your dialer
*#*#2846579#*#*
Select "software upgrade"
then Select - > SD card upgrade.
And then it will reboot and install the stock firmware.
This thread has all the Stock firmwares.
https://forum.xda-developers.com/mate-8/general/huawei-mate-8-stock-firmware-official-t3391727
Hope the above steps solve your problem. If not, then we will try something else. please answer all the questions to help you better especially your full build number (firmware version).

Since you are on nougat with test keys, try to flash the latest nougat firmware on your phone model NXT-AL10 (Try flashing firmwares using TWRP )
Link for the firmware
link 1 https://mega.nz/#!Y4IVEbxY!7C8u3FP3V8eAV4jVNmbRUfj2W1nc8p5gMtaScVmzeA0
if the link 1 doesn't work then try link 2
link 2 https://mega.nz/#!U9ZkTZzI!fbPnyDIxCGGFkiGxtF3SMicLqmTDNTq8SG8fVw8lfz8
download & flash it using TWRP.
Once you finish flashing - you should have android nougat stock B584
Go to settings - > about you should see that B584. in build number.
If your build number is showing anything other than test-keys then you will be able to use dload method or Hisuite method using PC.
Now if IT IS showing B584, then you can dload to B386. then unlock bootloader -> TWRP using SRK tools - > Root - > and then debrand to L29C432. - > this is the road map for you. we will go through this only after you succeed in the above steps.
Try the below steps only if the above steps don't work
if you want to flash the nougat recovery
then unzip the zip file in link 1.
Use Huawei update extractor software HuaweiUpdateExtractor_0.9.9.3
and then extract the recovery.img from the update.app file.
now
switch on usb debugging in your settings.
switch off the phone
press & hold volume down and then connect to phone to laptop
put the extracted recovery.img file in the same folder as the SRK tools
open SRK tools
type 000 to enter command prompt
type fastboot flash recovery recovery.img
(please remember all these steps that use adb commands come with element of risk. so please proceed with caution and go slow. Proceed with these steps only if you know what you are doing otherwise do not proceed)
Try the TWRP steps first and see if that will resolve your issue before flashing any stock recovery. If your flashing through TWRP then it will install stock recovery & stock ROM.
Please share your progress.

You must know that I'm very grateful for your help
Do I have to format data before start flashing B584.zip or do nothing?
Do I need update_data_full_all_cn.zip ?

Glad to read Ur kind words but V have a long road ahead. So let's fix ur phone :good:
Answers
1) Yes, you can format DATA before flashing this zip file. you can also do factory reset before flashing the zip file. (Remember we are doing this step only to get ur phone out of that test keys & this firmware is not ur final firmware that u will use. )
2) I was searching for a firmware that u can flash on ur phone and I found B584 and felt this might help. The guys in the other thread mentioned it as full firmware. After u flash this firmware, check in settings - > about - > build number if it is anything else other than test keys then u succeeded in this step.
Goal of this flashing of B584 is only to get rid of that test keys in build number. Once that is gone then U can downgrade to B386 using steps in my previous posts followed by the road map.

Hi, I have tried all night to install a custom rom and recovery for my huawei p9 lite (VNS-L21).
I've managed to flash Ressurection Remix with Meticulus' TWRP but now my sim card doesn't work.
It's detected but i can't make calls, send messages or use data.
I want to go back to stock EMUI but i don't know how exactly. I've found an update.app for my model but it won't install. I've lost my recovery and i can't flash a new one despite the bootloader being unlocked. Can anyone help me please or guide me how to restore it back to it's original state?
If it helps it was the VIP mobile Serbia model, CM-hi6250.
Thanks in advance, I really want to just have a working phone

If you lost Twrp you must flash it via fastboot command. After that it is neccesary to flash Oem C432 zip. In that step you can chose if you want oem for single or dual sim. I suggest to flash Oem C432 dual sim using TWRP.. On SD card you need to place in dload folder firmware full b160 in format update.app. When the Oem is flashed turn off phone (please dont let to reboot phone after flashing of oem ) , press power+volume up+ volume down, hold them a few seconds after you see logo screen, release buttons and full revovery will start. Oem L21C432 dual sim flashable zip file you can find here or in our local forum on benchmark.
All the best.

i had this problem too cause i was not attentive...
Create a dload folder in your sd card and search for an "update.app" file that is right for your device. Place it in the dload folder then press power button+ volume up+volume down to do a force stock ROM installment after install remove sdcard enter stock recovery make a wipe...restart done
Tell me if it works<3

You can instal via recovery from SD card "Service ROM" B416. But your customization must be C432 , dual SIM.
