Latest update from huawei did the following to my phone which was a rooted mate 8. ( losing root access was a given i guess )
No bluetooth
No google account
No file manager
No virtual keyboard
No alarm clock
Google voice set to default with no other alternative....AND it doesn't work!
Themes don't work.
Factory reset stops at around 22% with an exclamation mark
Pretty nifty for a 5 minute "Official" update.
What am i supposed to do with this lump of hardware?
I have my bootloader code, i have srk tool. I was originally on b190 buildnumber, then went to b200...and now this. Can someone please suggest which build number i need so i can then find the right instructions for the downgrade or whatever it's called.
U need Rollback package

if you have Huawei Mate 8 L29 model & if you are on Android Nougat then you need rollback package
Here is the link
http://consumer.huawei.com/sg/mobile-phones/support/downloads/detail/mate-8-sg.htm?id=91647
This is straight from Huawei and it is really a life saver. Only this file will work in dload method for you at this moment especially when you have NRD test keys or want to downgrade form nougat to marshmallow.
Download the file
Extract the update.app
Make a folder in your external SDcard and name it as dload
Place the update.app in that dload folder.
You can dload method 2 ways.
method 1
switch off your phone
press and hold volume up, volume down and power button all together
Once you see EMUI on your screen release your fingers from the phone.
method 2
open your dialer
type *#*#2846579#*#*
select - software upgrade - > SD card upgrade
that's it.
Once you are done. You will be on C900BXX build number. Then you need to dload another firmware. And which firmware you need to flash is based on your phone region and model. Is your phone previous firmware L29C185BXX ? if yes then you have to flash L29C185B180 or B192 according to your model. This is really important. Please share your complete build number.
Once you succeed in these steps then we can discuss how to move forward and what to flash next.
Hope you find this information useful and hope you succeed.

The region is Australia
Build number before this superb update was nxtl29c18b200
Now build number is NRD90 test-keys
Not that im being picky or selfish perhaps but is there a stable firmware which has low power consumption, themes work, better operation performance?
By the way, both of the above mentioned methods don't work. I got an exlamation mark and a message saying update doesn't exist after only 5% of updating
NRD test keys to Stock

So you have NXT-L29C185B200 is that correct? you can check this in settings - > about -> build number
you are not in nougat so please do NOT use the file in my previous post. (that should be used only if you are in nougat)
At the moment you are in marshmallow EMUI 4.0
If you have unlocked bootloader and TWRP installed then flash L29C185B180 (stock firmware)
Link to that firmware - > http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v51422/f1/full/update.zip
For unlocking, installing TWRP you can use SRK tools. I hope you have SRK tools, if not you can get it from this thread
https://forum.xda-developers.com/mate-8/development/tool-srk-tool-huawei-t3369797
and from this thread you can find how to use SRK tools to unlock and install TWRP.
https://forum.xda-developers.com/mate-8/general/vdo-guide-how-to-srk-tool-huawei-unlock-t3409707
There is a video tutorial on how to do this.
Link to the thread where you can find all Stock firmwares is here
https://forum.xda-developers.com/mate-8/general/huawei-mate-8-stock-firmware-official-t3391727
For flashing the firmware
1) Factory reset
2) Format DATA
3) Flash the zip file from the above link.
Android Nougat is Android 7.0 version. and the corresponding firmware's start with L29C185B5XX
First let us get rid of that NRD test keys then you can your phone can be updated to latest firmware easily. I will explain you in detail once you succeed in this step. Don't worry about errors.
Hope you succeed.

I am sorry I should have been more specific. I meant before NRD test keys, your build number was NXT-L29C185B200 ? (C185 is region specific) C432 is for Europe.
And now you have EMUI 5.0? then you can use the rollback package.
Here is the link
http://consumer.huawei.com/sg/mobile...g.htm?id=91647
I thought you were in marshmallow so I suggested you not to use it. But if you are in Android 7.0 (Nougat) then you can use the rollback package.
This rollback package will downgrade your phone back to Marshmallow and then build number might say C900BXX. It should get rid of that NRD test keys.
And after that you have to flash the stock firmware using dload method
Link to that firmware - > [url]http://update.hicloud.com:8180/TDS/d...ull/update.zip[/url]
Correct link - > http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v52952/f1/full/update.zip
Then you can update to any latest firmware. There are many ways to do this.

Bro, you can download the firmware using firmware finder..you can install it from play store..then choose your model and region. hope this will help you.
Edit: Sorry i just checked your latest firmware is what you're using right now..sorry bro..i think you can debranding the phone then flash new nougat firmware..you can choose either europe, asia or middle east for the region. there are tons of thread to do this..
i do a rollback but build number get c900 instead of c605 of my region. original insrtuction PDF speak about a file called SDupdate_Package.tar.gz someone know about this? Im using a nxt-l09c605
I have read so many posts and I am unsure what it is I have done to my phone but every time I update it to Nougat 7 / Emui 5.0 it is always on NRD90M Test Keys.
In TWRP I often get unable to mount Cust and or Data and sometimes Vendor.
I have rolled back to MM and tried the Charles Method. With Charles Method it rebooted the upgarde from MM but again it was NRD90M.
When in MM the build number displays correctly such as 122 or 162 but as mentioned every time i upgrade to Nougat it always says NRD90M test keys.
Other notes, I have once flashed RR and Lineage on this phone and it was successful. I also may have flashed some boot or other similar files to partitions but cannot recall and anyway I have formatted data, relocked and unlocked and repaired file system and still have had the same issue when it comes to EMUI 5.0.
I am in Australia and do not receive OTA updates but have use FF and Charles method.
Any help would be appreciated as it has been weeks and weeks of trying this.
Thanks and from memory I do remember at one stage all was fine and I was on build number 320 or 360 and then flashed Elite Kernel which did not work and did not allow me to boot.
Anyway, please assist.

I have the same problem, my friend, can you solve it? If you got as you did
i am sure your phone is still alive, because when you use HWOTA method to flash rom, you need flash twice , first time is rebranding, 2nd time you need choose updating .

Hello. I have on my phone emui 4.0.1 android 6 B860 ota. I tried to put Viper4Android and I broke rum, tel. I start my functions on it, when it sounds I do not hear anything, and also if I want to listen to the music. How can I return to lollipop, will I make it functional? Your phone has the Chinese version.
