Problem downgrading to MM from N

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

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 .

I'll change AL10 to L29C432 when I can do that

So maybe you help me unlock bl (I have unlock code) and flash TWPR....

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.

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, my english is bad too , B389 is an OTA update, its impossible upgrade via fstboot or via TWRP (error 7). IMO the right way to fix your problems - downgrade to MM , then back to Nougat etc. (remove pattern Lock , Fingerprint lock, root etc. before installing downgrade). It will erase all your phone data!!!
Download official rollback package for your VNS-L31C432
http://download-c1.huawei.com/download/downloadCenter?downloadId=93789&version=373429&siteCode=sk
and download MM firmware VNS-L31C432B161 (Single SIM)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66022/f1/full/update.zip
1) Create a new folder dload in root directory of SD card (root directory : it means dont put it in any folder .) Now unpack the rollback package and copy its contents “UPDATE.APP” to the “dload” folder. Use the 3 button combo installation. After your firmware version should now be on “B300” or "test-keys".
2) Remove from dload folder rollback package, extract the ZIP file with MM firmware to the dload folder and use 3 combo button installation.
Or you can use this method : on your phone launch the phone dialer app and dial *#*#2846579#*#*. Next, select Project Menu – > Software upgrade – > SDcard upgrade – > and confirm the flashing process that is about to be initiated.
Good luck!

Yes, you can. Via OTA, or you can use TWRP (Meticulus 3.0.2.0 only ! ) and flash both .zip files. You must download two files:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v80474/f1/full/update.zip
and
http://update.hicloud.com:8180/TDS/...-L11_hw_eu/update_data_full_VNS-L11_hw_eu.zip.
In TWRP set Install, then select memmory SD card, and klick on
update.zip, confirm installation. After, STAY in TWRP, go back to Install, find file ...hw_eu....zip , confirm installation. Then select rebot system. Done!

Try it, but I think, you will get a message "not compatible" . Via dload its impossible, IMO use rather Huawei firmware finder or wait for OTA update.

If I said, it's impossible manually update to 381 or 389 using OTA firmware, trust me . Try Firmware finder. GL!

FF works with proxy fine, but you must first download and install Firmware finder proxy apk. On Nougat use TWRP 3.1.0-2.

accidentally wiped /system on TA-1021 Germany

Hello everyone,
i messed up: i did the Dec Update for my german Nokia 6 TA-1021 with the updater and the weird chinese "TWRP". Well the recovery made a clean flash with the update file but it only contained a dirty flash update... So basically i need a full firmware for Germany (unbranded) TA-1021 :crying:
For me it does not matter what version since i can update it from there. Is there anyone out there who can help me?
Thanks in advance

Hello zio!! keep calm and have a long breath!!
Flash this with ost:
http://https://mega.nz/#!5ccRnb4b!VsgiKQ4CjxFyjbjcxR0esjeKmHZsUTnEz0FA_FMZQbM.
Don't tap edit phone information but just flash!! the security patches are from july!!
if you have a bad flash try to wipe from settings => restore
Stay away from rooting process until nokia releases the dedicated tools, capisce!!

What i told you 1 minute ago? keep calm!!! i have myself a nokia 6 and i'ts a 1021. this rom is for that version!
i've flashed this rom and my nokia is still alive.
The most important thing is boot the phone in download mode, i'ts half of work

[solved]
I solved it this way: i downloaded the patched OST from here: https://forum.xda-developers.com/nokia-6/development/nokia-6-official-firmware-mena-region-t3664441.
The ZIP of canaop92 did not work for my phone (see EDIT), but gave me a nb0 file for the following
I clicked "edit Device Information" in OST, DO NOT CLICK ON 'NEXT' after that
This installs a functional fastboot onto the device.
The method of canapo92 did not work, explained in my EDIT. So I had to improvise: I downloaded (after an hour of searching for that) a full firmware of the Nokia 6 TA-1021 and mirrored it:
https://drive.google.com/file/d/1kCKSid5Bf89yA3DyX8Y2gAZHq4VK6_p6/view?usp=sharing

https://1drv.ms/u/s!Agmh3wcexsuyjWysvmeASmEW66ah
https://nextcloud.hobbyist-overclock.de/index.php/s/RX7SxFQcLF7Pj9B
(download one of the mirrors)
Then I 'fastboot flash'ed the following .img files to the device: boot, cache, cda, hidden, mdtp, misc, persist, recovery, splash, system and userdata
That was it - everything working again
Thanks canapo92 for the Help and the original download link
EDIT: the flash without edit phone information did not work, my phone rebooted itself into recovery... weird... so i experimented. I tried to repeat the process with Android working again and now it wiorks

I followed all your steps, I flashed all the .img on my phone and at the end all the OTAs were downloaded until December, but still showing the model TA-1025, not a TA-1021 like I wanted. I've also done a hard reset, but nothing has changed.

Look buddy, when you bought your, at that time if your phone showed up TA-1025 then after flashing it will show you 1025, if it was TA-1021 then it will show you 1021.
You dont have to check the build.prop file, as every nokia 6 TA-1021 shows TA-1025 into its build.prop file
Flash your phone with MENA firmware, it will flash your phone to 1021 or 1025 with june security patch update
Then apply all updates till December
Everything you can find from here https://forum.xda-developers.com/nokia-6/how-to/guide-oreo-follow-steps-t3723776
Follow all the steps care fully
If you want to update to oreo then
Sign up with beta labs from here https://www.nokia.com/en_int/phones/betalabs
And check if your phone gets the oreo update or not
If not then follow this thread for manually update to oreo https://forum.xda-developers.com/nokia-6/how-to/guide-oreo-follow-steps-t3723776
Remember OTA will require wifi connection to get into your phone
Also be calm and read every step carefully, this will take you to least chance to get stuck into any problems.

Thanks mate, but I have not explained myself well. My phone is a original TA-1000. I have flashed it following the thread of the MENA firmware and then it shows that it is a TA-1025, up to there everything is correct because he only downloads all the OTAs until December, 7.1.2 included. The fact is that I wanted to flash it to TA-1021 to see if I can solve the problem of the horrible sound in calls and that's why I tried to flash this ROM of TA-1021.

Then i would like to tell you that, there is no firmware which is made for TA-1021, the varient varries from region to region
If you phone 1021 then it wont change to 1025 and if it 1025 then it wont change to 1021, may be it is the reason that you get device name as unknown right
The mena firmware is an international varient...
Well i would like to suggest you, that if you want the features then u might go with mena firmware and if you want to fix these then i would suggest you flash back the chinese varient and wait for developers to develop a good custom rom for all users...
Till stay relaxed, and if i will get any fix for it then i would surely share those methods..

Okay, your friend told me that you have gained recovery access again. Please do not worry, we can rescue your phone.
First, you have to do Step 1 and 2 of this guide: https://forum.xda-developers.com/nokia-6/how-to/guide-upgrade-downgrade-nougat-oreo-t3752393 but you have to use a firmware file that matches your first letters of your phone's serial number (codename) like PLE or D1C. Using the firmware from other phones can cause unexpected issues but it should boot. Reboot you phone, it won't boot there but that is normal. Apply the OST BL patch again and then you can proceed with 'fastboot flash'-ing the full Nougat firmware or try the homebrew firmware from @hikari_calyx

Now what we will do is flash the twrp, for this we must already have the unlocked bootloader and the fastboot drivers installed and put fastboot flash recovery_ramdisk xxxxx the x means that you will put the name with which you have the recovery.
once we have the twrp what we will do is unzip the firmware zip and move it to an SD card as it comes, do not touch anything in the folder
Once in twrp and the SD card set, we will enter the HWOTA folder and we will touch in the lower right where it says install img, once touched there we will look for this file EMUI-v9-NoCheck-Recovery.img
we touch and flash like Erecovery, and we slide, once finished, we touch the lower left part and we put it install zip, and we look for the zip that is called, EMUI-9-externalSD-Firmwareflash.zip and we slide, once I do the phone it will restart and begin the downgrade to EMUI 9, any questions comment
