After replacing the files, when returning to the updater, it writes an error, deletes the 2 files, and restarts the download of the b368 update.
How did you avoid this?

Return to the updater of the phone and be sure that you download the appropriate files of nougat

You must give the same name of the second files of b368 to the nougat file its mean that you must delete«full»from nougat file

And important question: after flashing nougat, is your MATE 8 working for all features ? Wifi, Bluetooth, etc. Have you made some tests ? I think it may help several of us to take their decision to flash or not...

It will work at Chinese areas but outside china ypu may have data issues

But I have already an NXT AL10 version, that I use in Europe since 9 months now...It's on EMUI 4.1 and b386 ROM, and it's working like a charm, maybe some apps remaining in chinese, but really not a problem. So, if I update to NOUGAT and EMUI 5, may I have the same features working as with EMUI 4.1 and b386 ROM (essentially basic feature as 2 SIM slots, WIFI, BLUETOOTH, DATA connection, Play Store, etc...) If YES, I wiil try to flash...

Yes every thing work fi

I had the same problem and that mean two thinks:
1 the name of the two files isnt the same
2 or you didnt diwnload the correct files of nougat

This is the two files of nougat b562;
update.hicloud.com:8180/TDS/data/files/p3/s15/G1255/g104/v69008/f1/full/update.zip
update.hicloud.com:8180/TDS/data/files/p3/s15/G1255/g104/v69008/f1/full/all/cn/update_data_full_all_cn.zip

When you download them change the name of the second files to this:update_data_all_cn.zip
Note: Its beter when you do this by your computer

And When exactly, during the update process, do you replace those 2 zip files inside HWOUC directory ?

Yes

Ahh, I've tried to update it on my DL00. It didn't work.

Its not for dloo its for AL10

But its same way the difference is in the files of nougat

We need ''update_data_full_dualcu_cn.zip'' for NEXT-DL00C17B562 and ''update.zip''

I am on VNS-L21C432B336 (beta) and i'm unable to install B370 via FF proxy. After downloading, it fails verification with error "failed to authenticate the package....will be deleted".
I can't post in the P9 Lite thread, so i am trying here, if someone can help me.
Do i need to downgrade to MM, B160? Cam i update to 370 via dload folder and 3 buttons method without downgrading?
I already tried rollback via this metod http://forum.xda-developers.com/huaw...vices-t3563955 and after 5% it gives the error "Software install failed! Incompatibility with current version. Please download the correct update package."
Do i have to do anything else before loading the rollback file onto the SD Card in the dload folder?

I used the exact rollback package to rollback from b371 incomplete build to b160 and worked great...

Is my phone supposed to be rooted, or have TWRP installed for the operation to be completed successfully?
I tried 2 times and it always fails at 5 % giving the error "Software install failed! Incompatibility with current version. Please download the correct update package."

The phone should be unrooted with stock recovery for this to work.
Did you try directly updating to b370 or 371 via 3 button method ? Not sure if this would work but this is what I would try to do if I we're you.

When i bought the phone, the bootloader has already been unlocked, and TWRP installed. I wanted a clean experience so i flashed the beta 336. TWRP is gone, so i belive is not rooted anymore. The message at startup still shows up that " your phone can't be trusted". So is the bootloader locked now? Can it even be relocked?

I don't know the answer. As far as i know flashing b336 should relock the bootloader and get back to stock recovery. In development topic there is a discussion about going back to stock. Maybe there you will find the way to get back to stock.
Don't try to flash b370 or b371 if you are unsure that the bootloader is locked. I will search more info on this and get back to you if i can find something.

I have read on the forum that is not possible to flash b370 directly from b336. If it bricks the phone, how will i flash another stock rom? I was planning to rollback to b160 and upgrade to b370 using the firmware finder and the stock updater. I might give it a try, flashing the B370 directly. Also, will i need 2 files, on the dload folder? The update.app and the big 1.94gb image? Thanks
Also, if huawei finally releases the B370 OTA. will i get the update automatically if i am on beta?

Helpful video
I was having difficulty figuring out how to use Firmware Finder when I upgraded to B360 on my VNS-L21. Then I found this video, and it worked perfectly.
Forgive me if this is old news, but it may help someone who is also having difficulty:
I am unable to post the YouTube URL as I am fairly new, but search for this title: "[How to] Using Firmware Finder by Team MT. Installing any firmware from Huawei update server."

I finally managed to find the courage to update. Went smoothly. I can confirm that Firmware Finder works, but be careful to download the right package. For B160 - B370 and B161 - B371. Both are 1.94 GB in size. Nougat is very nice and all features work as intended. Lets see the battery life now...

Detailed guide to downgrade from Nougat to Official Marshmallow (NEM-L22)

Detailed guide to downgrade from Nougat (unofficial or beta) to Official Marshmallow.
Saw many users struggling with unofficial Nougat update (via firmware finder) and were looking for downgrade procedure (on Facebook, honor community and on XDA) to go back to stable and official Marshmallow version from Beta/stable stock Nougat version. Below method is thoroughly checked personally by me for more than 5-6 times and I am writing this detailed step by step guide for downgrade.
Prerequisites-
Non-rooted phone (no changes to the system partition and bootloader made)
Make sure you are running the Nougat version B3XX (not custom ROM)
Make sure you are on stock recovery.
Make sure to take full backup of the data and apps as this downgrade process will erase all your data and will wipe the internal memory. (you can use this backup to restore your contacts, call/sms logs, app with data, your home screen layout etc.)
Make sure your device is charged to at least 50%.
SD card with minimum 4 GB free space (as main product package is around 2.77 GB in size)
Let’s start the process.
Updating product transfer package-
Download the update.app product transfer package for Honor 5C device from link https://goo.gl/KYZ3Pd
Create a folder dload in the root directory of your SD card.
Copy the update.app package which you just downloaded to dload folder.
Power off the phone.
Press volume up+volume down keys and simultaneously press power button.
Your phone will automatically detect the package and will start the update process.
Once the update process is successful, you will get a message as update was successful and your phone will restart automatically
.
Updating the main product package (Marshmallow B151 package)
Delete the old dload folder from SD card. (which had transfer package file of size 69 MB) - Do not forget to delete this folder or rename it or else the same file will be keep on flashing again and again.
Download the full version package from the link https://goo.gl/8d4s73
Copy the entire folder with UPDTAE.APP file in it to root directory of SD card.
Power off the phone.
Press volume up+volume down keys and simultaneously press power button.
Your phone will automatically detect the package and will start the update process.
Once the update process is successful, you will get a message as update was successful and your phone will restart automatically.
During restart, phone will verify the system image.
This verification and 1st boot may take upto 4-5 minutes so do not panic.
Once the phone is booted and up, it will ask for the initial setup like language, wifi, agreement etc.
Validation-
Once the phone is setup, go to setting—about phone—check the android version and build number to verify you are running on Android Marshmallow version.
NOTE:
This process will completely erase your data, so make sure to have a backup before proceeding further.
This process will downgrade your phone to Android marshmallow, EMUI 4.1.2 and B151.
I have personally tested this method and downgraded my phone to marshmallow without any issue (10+ times)
If you follow the guide correctly, you should not face any issue with condition that all the Prerequisites are met and you followed the steps in order.
If anyone still have any doubt or a slight hesitation, please feel free to ask in the comment before proceeding and risking your phone.

I have a doubt
Hi shashank,
I am using honor 5c Indian version running in naugat. My phone is very slow. If I downgrade to Android 6.0 will get speed??. Because my handset was smooth when it was marshmallow......

i think you are mistaken since some guys have reported successfully doing it ...
in any event if you can't downgrade using dns try downloading the complete OTA package and try doing it in erecovery on your phone ..
failing that you might as well try every method you can find that is related to "restoring" your device using the old OTA package ..
however since this is the only downgrade option AFAIK you are SOT if you can't make it work but you are probably just committing an error or have a bad internet connection etc etc and however painful it's in your own interest to keep trying ..there is just no one button press solution for you ..
i saw somewhere one of the things you can pay dc unlocker for is downgrading but tbh i don't know if it works or not so can't advocate it ...
sorry to hear about your bad luck but if you can't make the above work .....you post a solution if and when you find it to help other guys ...

you can try to download the full OTA update package with firmware finder ...then put the update.zip on internal sd card in folder dload ...boot into erecovery and try to apply the zip ....worth a go..
read & try all these methods
https://boycracked.com/android-tuto...-unbrick-firmware-any-huawei-android-devices/

I've been aware that firmwares from Firmware Finder don't work in order to downgrade. You need a full firmware, look for it at https://androidhost.ru/ be sure to search your MODEL and CUST, the lowest build number available. Then extract DLOAD folder and put it in your external SD card, inside this folder you should see update_sd.zip and then another folder with your model and cust which is named update_full_sd... or something. After that go to dialer, type in #*#*2846579#*#* then software upgrade - sdcard upgrade (this wipes data so make a backup). In the end you'll end up with an older firmware so you can use DC Unlocker. I did it in that way and I was able to use the unlock service.

Is there "huawei identity" part on your rom? Is software OTA update available?

Can confirm this works but i had to do using my pc as a wifi hotspot and setting the dns using speedify proxy due my router not having the options to change the dns. Use TEAM MT Firmware finder pc version and follow the instructions then open hisuite and it will downgrade for you, i was then able to unlock my bootloader with dc unlocker and root with magisk.

I took the telephone to a shop for firmware repair. He tried for a couple of days and he also couldn’t get back to official software.

I can guarantee that its possible even with a locked bootloader aslong as the you are placing a signed firmware onto it.
The method needed is quite a pain, the only way i got it working is by making my pc into a wireless hotspot and altering the DNS from there then in firmware finder you need to register the firmware to you imei/ip then you can either try with huisuite or through recovery to click to check for updates and instead of it asking the official servers it ask or checks the firmware finders dns server which then confirms there is an update

Stuck on NRD90M test-keys

Team,
I've got a problem. My brother got the phone locked on NRD90M test-keys and can't roll back. I've tried getting into the SD card the UDPATE.APP for my model (VNS-L22) but when doing the three key method it shows an error message with something like "incompatibility with current software" and it just gives me the option to reboot the device. I have access to the device as it boots but things like camera stopped working (it's been a while since he did that and he just told me)
I've tried with the "Huawei Recovery Updater thread" here but I don't know if I am doing something wrong or what but it does not work.
Reading a bit more it seems I've to unlock bootloader and do a bunch of things, just wondering what do you think is the best approach or how can I get back to stock ROM, so we he can get OTA updates and have the device working without a problem.
He did this by using the Firmware Finder app from play store, so I guess he did an update and got the device on that state.
Device details:
EMUI Version: 5.0
Android Version: 7.0
Huawei P9 lite
Model: Huawei VNS-L22
I appreciate all the help you could provide,
Thanks!

Hello,
if you remember exactly the complete firmware your device were on
before been stucked on NRD90M test-keys, maybe using Firmware Finder ( FF )
you'll be able to force the update to a newer and working version..
( ex. mine was VNS-L31C432B381 and updated to B415 )
The other method is most complicated...
Unlock the bootloader, flash a custom recovery and use
Huawei Recovery Updater in order to reflash your stock rom.
Then you should use FF too to make an update and correctly
relock the bootloader.
Is you'll use those awesome apps don't forget to thank the developers.
Cheers

Yes I do, actually I just realized the one I could find here wasn't the same I had before so maybe I will try that one. I tried firmware finder from the app but it wasn't working properly, when downloading the FULL OTA files it started crashing and then I was not able to proceed with the "downgrade" now i've used the FF for PC and downloaded the files from FULL OTA, however there are 3 files. I am not sure what to put into the dload folder.
These are the files:
update.zip
update_data_full_hw_normal.zip
update_data_full_ice_cr.zip
As per my understanding I should place only the files from "update.zip" right? I also saw a few comments on a video that said put all content from all three files into the dload folder.
If you happen to know the answer I will appreciate it!

Hello,
I'm also stuck in this rom... But in my case I went from a custom ROM to it. But it blocked my bootloader, etc...
And I forgot my bootloader code
Now I have to unlock it and I will use DC-Unlocked but when I dial this number: *#*#2846579#*#* in this ROM it doesn't show anything!!! So I can't open Project Menu...
What can I do?
Thanks

Dude,
you cannot use DLOAD aka three buttons method
on nougat ( android 7 ) 'cause it wont work.
As i wrote you should know exactly the firmware your device were before the softbrick.
Getting 'nrd90m - test keys' firmware probably mean you already tried to use a wrong firmware.
I don't know whic firmware you downloaded, but i can assure you without that correct no methods will work.
As you can see in the attachment exists many custs ( C185, C569. C576, C635, C636, etc... )
and firmware ( Bxxx ) that indicate the region/brand were you live or where the device was sold when you bought it and if single or dual sim.
Without those info become a lot complicated bring back your device in an working state.
The last chance should be a rebrand but you need some files like OEMinfo zip but ever first you should unlock the bootloader, flash a custom recovery and use HWOTA method, but the risk
to completely brick the device is really high.
Example of a firmware : VNS-L31C432B415
VNS ( venus is the name of the device )
L31 ( is the version of the device )
C432 ( is the cust that indicate the region where was sold )
B415 ( is the running firmware/security patch on the device )
You had VNS-L22 C??? B???

Dude,
before attempting to unlock again the bootloader
you should try to force the update with Firmware Finder.
What was the firmware you were on before flashing your custom rom ?
Which custom firmware you were on ?
How you gone back to stock ?
Which stock firmware you used to go stock ?

So the firmware I had before doing that was VNS-L22C106B150.
What should I do with that if the android app is not working? I mean... I tried doing it with firmware finder and it didn't work, used proxy thing, dns thing, downloaded the files (multiple errors, files corrupted) and it is not my internet connection, it's the app. I did downloaded the files on the Windows app

Ok, if you sure your firmware are L22C106, things aren't so good.
Cannot make an update, can make a downgrade but you need the correct rollback package
and i don't know were you can find it, but in any case you couldn't re-upgrade to android 7.
Checking in the FF PC 's app, as you can see, no nougat
versions of this firmware are present. Which version you downloaded before ?
If you are really sure about that firmware, you have only a possibility, which is
make a rebrand but it's a bit complicated and really dangerous.
Choise remain yours, you can find some guides how to do a rebrand, just search
in the p9 lite threads.
