Download latest firmware(b560 or b571 depending on which region you have and you have Asian for you it's b560) update.app to your sd card and update it.
if it's not try force update by putting update.app to sd card and then turn off your device remove data cable and then press volume both and power until Huawei logon show after 5 or 10 second it'll flash rom you download.
or if you want to downgrade you have to download rollback 6.0 to 5.1 package and flash it by putting file in sd card and update basically its not update but downgrade to 5.1..

Hi , thanks for answering , i try each region update and everything is failing .
Thy tried ways is force update as you mention and by the code from the dialer .
(before the trying to update ) I dont know if the bootloader is unlocked or not but i root my phone then unistall it , then try to unlock it by adb .
Do you think if i relock the bootloader i will be able to upstate / downgrade it ?

Update or downgrade doesn't need bootloarder lock or unlock
if you want to flash custom recovery like twrp to root or flash custom rom then it's compulsory to have unlock bootloarder.
what exactly you want to do if you want to downgrade it have different method and if you want to update then make sure you have unlocked bootloarder by pressing vol- and power it'll show lock or unlock it's doesn't matter for downgrade to have lock bootloarder you should download exact firmware for device I also have same region mate 7 tl10 Huawei make lengthy process to update steps by steps if you are on b512 you should download b560 for your device try this to have some easy step for unlock bootloarder recovery,root

[Guide] how to update mate 7 without getting error in recovery {update failed}

This guide is for all those who are getting error while updating their mate 7 manually either by local update option or by 3 buttons combo option.
here we go: ( for eg. consider mt7-tl10 model imternation version currently on any firmware and you want to install b123 firmware )
1. Extract recovery from new update.app to be installed i.e. b123 firmware.
2. flash it in fastboot mode.
3. now try to update using any of the option either local update or 3 buttons, it will run smoothly and you are done.
basically first we have to install recovery of the new version we want to install.
same can be followed to easily update to lollipop firmware.
hope this might help someone
Thanks - I was wondering what I was doing wrong since I can't update anymore either OTA, or local update or three fingers method, I constantly get the message "software update failed" and I am stuck with KingUser.apk ...
Can I ask I few more questions (I have changed ROMs in other mobile phones but not on the Mate 7)...
1) Do I need to unlock my bootloader to flash anything (I assume yes, my phone is still unlocked) ?
2) Do I need to use the Huawei Extractor (this one: http://forum.xda-developers.com/showthread.php?t=2433454)?
3) The name of the recovery is recovery.img (I guess so)?
Thanks a lot,
Paolo

Help updating NXT-L29 Rom: NXT-C900B320 to Nougat via SD Card Update.app method

Hi I've tried using several NXT-L29 Nougat roms but they all fail
Notes:
- My device is not rooted and I can't root because several business apps I use won't run on rooted phones (banking, etc)
- If the OTA update for this ROM is available in the next month I don't mind waiting.
- I've successfully updated my ROM twice before by putting an update.app in the dload folder on my SD Card
- I don't care if I have to restore my phone from a backup and lose my data
- I've tried downloading several NX-L29 and NXT-L29 Nougat firmware and none of them have worked.
- I tried unlocking my bootloader using several methods (including paid ones) and was unsuccessful
I'm only after an official stock firmware and would like to just copy the update.app to a dload folder on my sd card to update unless there is another safe method.
I suspect I'm just using the wrong ROMs or perhaps missing a step.
Can anyone point me to which ROM I should use or give me any tips on how to get around the problems I'm having?
You and update via UPDATE. APP
I'm in the same boat as well...
I want to upgrade but don't want to root.
I am tempted to use firmware finder to load it across and install it via the system updater...
I thought the official update would be released by q1 2017 so the end of March....

I tried using DC Unlocker, but it wouldn't give me the code I needed to unlock. I only have Windows 10 Enterprise/pro machines and tried on several but no go.
Vendor: hw
Country: spcseas (Malaysia I believe)
I don't mind using TWRP, but as I mentioned, I can't unlock the bootloader. I spent several hours trying this.
Widows 10 also working i have the same as you
When u connect to dc , choose factory mod
Don't operate usb debugging function
And then do the process

I downloaded an udate usg a firmware download app. It did update my device, but bluetooth isn't working and it gives an error when booting. I'm trying to now wipe it and start from scratch by unlocking the boot loader and using twrp.
Whats the best Nougat ROM to use and where can I get it? I tried downloading my old ROM do downgrade but couldn't find it anywhere and I have so many roms I've tried they all got mixed up and I don't know which one to use.. I'd go back to B320 if I could, but would prefer to move forward with a stable, compatible version of Nougat. Any suggestions on which ROM to try and where to get it?
Which rom ur phone now working on

Don't getting update to B560 again

My Mate 8 L29 is currently on C432B192 again. I said 'again', because I was already three or four times on EMUI 5. (I tried to root it but it failed Everytime, so I had to rollback)
Yesterday I wanted to try again to root B560 and began to search for the update, but - nothing. I tried it via update app , HiCare app and HiSuite on PC. I don't get the update offered. (I also deleted data and cache of those apps)
I'm currently rooted, so I tried to unroot, install stock boot image and recovery .. but same problem: still not getting the update.
Now I'm wondering why this is happening .. I had that same case before (B192, rooted etc.) and I always got that update offered.
Does anyone have a solution for this ? ( Except the manually method via TWRP .. this was never working for me)
Thank you for your help!
Hello everyone ...
I was trying to root my mate 8 next+L29c185b560 ... And I did with twrp
But I lost all huawie apps like hw care and backup and a lot ... And there is no keyboard and Bluetooth not working ... How can I get my phone to his original state ??? Without root without twrp but with all functions ??? Can any one guide me ?

You need rollback package to get it back to normal.
Since your model is L29 & you are nougat.
Go to this site http://consumer.huawei.com/sg/support/products/downloads/detail/mate-8-sg.htm?id=91647
Download the file
Extract the update.app
Make a folder on your sdcard and name it as dload
put this update.app in that sdcard
now you do the dload method
you can do it two ways
one way is
the 3 finger rule while bootup
just press volume + volume - power button together and hold until you see EMUI verifying package
then release your fingers
it will rollback to marshmallow
now you have to update it to another stock firmware (marshmallow)
remember at this point it is in global firmware it might show build number as C900 or something.
you can check it in the settings - about -> build number
you have to then update it to your model firmware
L29C185BXX
I found the stock firmware from another thread for your model
This is L29C185B200
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v65326/f1/full/update.zip
once again
download the file,
extract the update.app &
then put the update.app in dload folder on your sdcard
and then do dload method.
second way of dload is
open dialer
type *#*#2846579#*#*
click on "software upgrade"
and then -> SDcard upgrade
follow the instructions on the screen
and it will finish the dload method in next few minutes.
That's it. now you will be on Stock ROM with fully functional OS.
after this you will either get OTA updates or you can download using HiCare
or you can download the stock firmware from another thread
or
you can use firmware finder to get stock firmware for your phone. Get the latest version.
If you finish all these steps then I will tell you how to get to nougat if you have any trouble
Hope you find this information useful.

You are rooted & if I read correctly you also have TWRP installed.
If you are unlocked, rooted & have TWRP - then you can install custom roms.
but if you want stock roms, - you need Stock ROM, Stock Recovery, Locked bootloader.
First you need the rollback package from EMUI4.1 to EMI 4.0 for L29C432 is below
https://www.hidrive.strato.com/lnk/0mlDFqqy
Rollback package for L29 to downgrade from EMUI 5.0 to EMUI 4.0 marshmallow is
http://consumer.huawei.com/sg/support/products/downloads/detail/mate-8-sg.htm?id=91647
So choose the right version based on the firmware you are having on your phone. If you have nougat choose the second link and if you have any other version then choose the first link.
Download the file, extract the update.app
then you have to do dload method
create a folder named dload and put update.app in sd card
then
go to dialer
press *#*#2846579#*#*
select
sdcard upgrade
and then say yes
that's it
you will come back to stock (global) version. build version will be C900BXX
now you need stock firmware for L29C432
you can download the stock firmware from here. Below tis the link for L29C432B180
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v51244/f1/full/update.zip
Stock firmware for L29C432B192
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v63059/f1/full/update.zip
Here you have the option to either go for L29C432B180 or L29C432B192. (if you choose B192, then you will save time and reduce few steps, because you will get system update to B560 immediately once you change the region to Ireland in Hicare app)
do the dload method again
extract the file, put the file in dload folder in sdcard ,
either use dialer or use 3 button rule to finish the dload process
now you are on L29C432B180. / L29C432B192
From here you can use another dload method to go to B192 - > system update (OTA) -> B560 or B580
if you get a blank screen - > do factory reset
if you get "verification failed " in red color - > unlock bootloader again and proceed with the steps.
This rollback package will save you in case of any problems.
Once you go to nougat B560
you can update to Kangvip B577 - pre rooted rom - its awesome - Root stable , excellent battery lfie. - everything is working perfectly.
I will give you those steps and links if you succeed in getting to B560 after all these steps.
I am sorry that this is a very long post and many steps but I can assure you that it is worth.
Ultimately you will get to nougat & with full root using Kangvip B577.
Hope you succeed

Developers options missing

Hello y'all, i issued a problem tomorrow by rooting BLN-L21C432, i unlocked bootloader with no problem, when was time for flashing recovery, i flashed the boot into the recovery and issued a problem in the dev options and security. Cuz of that, i can't access to adb, hisuite hdb to backup, and can't install extern apps without autorizations.
I tried all night long to resolve but no way, add to that the fact i've got a very very low connexion so 3-4h to load an update.zip.
So i downloaded b370, no way i can't use the dload method, fail at 5%. Same issue with b369. Tried to flash manually system boot and recovery by extracting update.app, no result, it's same. Tried to Unbrick via multi-tool, i use it on honor 7, but there's no cust image in update.app.
Build number is normal, C432B365.
I don't know what to do now, it's 10 hours i'm losing my minds with that phone. Please heeeelp :crying:
From which firmware ? Is it good if i flash boot and recovery from B360 ?
Edit : Actually the phone is in B365, it would be better if i try to dload from it right ?
I read that unlocked bootloader could block an update, is that true ?

No u need to flash boot and recovery from actually firmware. After when u flash right boot and recovery (from B365). Now u try installing this firmware us it B360. http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v82485/f1/full/update.zip

If any downloading oreo OTA for 4G please make this previusly apply the update

Please... Its for link for download
Developer Settings enabled needed (no need root)
Once you receive the OTA notification, do not update and do not reboot.
Download the OTA and let it remain on the device.
Connect your smartwatch with your Android phone.
Launch the latest Android Wear 2.0 app on the phone.
Tap on the 3 vertical dots, which is the options tab, and select Report Wearable Bug.
