hello, i am new to this site i signed up just to ask this question. i have spent so many hours trying to find a way to downgrade / roll back to the previous version of my device, i have tried to download the stock rom and install it that way but it does not work, it just says it cannot install the update and suggests a website for me to download the stock rom from, which i then downloaded to only find out it still gives me the same error message, is there anyway i can downgrade to lollipop(emui 3.1) from marshmallow (emui 4.0). can i flash the files over or something, please help, also i have tried to unlock the bootloader and everything but it wont allow me to do that, also if you are able to help me root the device then i wont need to rollback to a previous version, kingroot and anything similar only was able to root my phone when i was on lollipop ever since i upgraded kingroot wont root my phone, any help is greatly appreciated, thanks
Really HuaweiP8max is unstable on android 6...? So I am not going to update to 6... Really sad
What is the main problem with 6 ?
I had been searching for a way to update my EVA-L09C636 (Asia-Pacific) model to EMUI 5.0. During the previous month I tried to install EVA-L09C636B361 firmware via either dload and Huawei Updater, but such means of direct installation never worked out.
Now the problem is solved, and the solution is quite simple, though a little bit unexpected: using Huawei Updater to install EVA-L19C636B190 before installing EVA-L09's own B361 firmware. I mean, it is interesting that we have to "borrow" the B190 firmware from the Dual SIM L19 model in order to update to EMUI 5.
(I'm not the first person to find the solution. I just found out that in a Taiwanese forum a tutorial is already posted. )
So there are two steps to install B361:
1.
Install EVA-L19C636B190 via Huawei Updater
Use Custom ROM URL
Copy and paste the link to EVA-L19C636B190:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v64578/f1/
Use the HiSuite on PC to finish the installation of B190 (Set its proxy to 127.0.0.1 and the port to 41279)
2.
Repeat the previous process, but this time, replace the link with the one to EVA-L09C636B361:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1256/g104/v73928/f1/
Again, use the HiSuite to finish the installation of B361
Note that the C636B190 version firmware for L19 model does run on L09 without the support of the L09-exclusive NFC. I think there should be a thread discussing this. Anyways, before official update comes out, the two steps above seem to be the only way to install EMUI 5 on the Asia-Pacific EVA-L09C636 version without losing data.
That is interesting, I dont have a C636 but I would assume just doing step 2 without the need to flash a L19B636 would do the trick.

I was searching for this for months. I bought my p9 EVA-L09C636 in the US (I'm european) and I never had the chance to update, even at 4.1.1. I went crazy because I tried several times to unlock the bootloader first, installing twrp and flashing updates but with no success. It's unbelievable that I need to fake the version with huawei updater to obtain the updates for my phone. Now I've Nougat, without factory reset, with everything working, from nfc to all stock apps and services. Thank you very much

Well, in that case it keeps failing at 1%. I saw some previous posts talking about this as well.
Need Help
My model is Huawei P9 EVA-L09C636
I tried to update like this, it's started updating and got an error while updating then phone rebooted with new update,
but there's lot of errors,
Built Number displays as - NRD90M test-keys
Updater missing in settings
Camera missing
Flash Light not working
Clock missing
File Manger missing
and few more default huawei apps missing.
How do I fix it or downgrade to previous version back?
Thanks finally I was able to update my P9 to Nougat using this steps. The only difference is that there is a EVA-L09C636B190 available now so i didnt have to use the version for any other cell, I was afraid to do it. So following this steps i was able to upgrade from 168 to 190 and finally to 361 version.
My Phone is Huawei P9 EVA-L09C636
Even though my phone is L09 I've flashed L19 by following the steps on this thread -
(https://forum.xda-developers.com/mate-8/general/nxt-l09c636b521-official-firmware-guide-t3544729/)
2016.12.29 - EVA-L19C636 - EVA-L19C636B361
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1583/g104/v74666/f1/full/update.zip
http://update.hicloud.com:8180/TDS/...ll/hw/spcseas/update_data_full_hw_spcseas.zip
it's still NRD90M test-keys. but i'm cool with it.
Works on AL00 as well?
I was wondering if I can get the most current european rom on my AL00 with that method as well?
Holy cow thank you for this tutorial.
I spent six hours following every tutorial I could find on the web and my P9 staunchly refused to install ANY update from the very next one after the one it came with all the way up to the latest!
After hours and hours of trying this method is the one that worked.
Edit: This firmware is a developer build.
There have been several updates installed since it was released.
After you this firmware it you should immediately install Huawei Firmware Finder from the Play Store and install the latest full OTA.
The developer build changes the device ID of your phone so you have to manually add the model of your phone in Firmware Finder as:
EVA-L19C636
Otherwise Firmware Finder would tell you there are no firmwares available for your model.
If you can't install the latest OTA immediately after installing this firmware, first install the next one available (38 if I recall correctly) then install the latest OTA -- 38 will say it failed to install but it actually installs just fine, then install the latest full OTA.
That will give you all the bug fixes and the security patches from Google.
Also note that this firmware works on both the dual sim and single sim models (it's built for the single sim but my device is dual sim and the sim configuration in settings works).

The build number is normal.
As for the disappearing apps, it sounds like you have faulty flash storage.
That will cause files and apps to randomly disappear.
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

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 about this problem on another thread but the problem was poorly explained and i couldn't follow to the processes explained on the replies, so i have created another new thread regarding this problem, because, in addition to being very useful for me, it might be even more useful for people that are searching for a solution.
I will explain briefly the scenario before talking about the problem itself.
I recently (1d ago) got my telephone blocked because of a Hard Brick that i managed to overcome using
DC Phoenix, from which i installed Emui 4.1 and then automatically updated via the built-in updater to Emui 5.0
As before my hard brick i was on a more recent build, Emui 5.1 (B394), i searched on the internet and understood that my current Firmware, "NRD90M test-keys" is a test build (or something like that) which can't be updated with the built-in updater.
So, i want to ask, in order to avoid getting bricked again, if there is a way i can update to the latest Emui available for my device, as in the current state the build, in addition to being obsolete, is also unstable and reports some compatibility errors, E.G. error retrieving microphone service when sending audio messages on WhatsApp, ecc.
i have heard of a method consisting of rolling-back the device to 4.1 again and installing 5.1 via Dload, but can you tell me how to do it more in detail?
EDIT:
Problem solved by rolling back to 4.1 b131 and then updated from internal updater app
Thanks in advance,
Federico

This Should Help You.
https://forum.xda-developers.com/honor-8/how-to/to-emui5-custom-roms-tested-openkirin-t3638445
I assume since you rolled back you have a locked bootloader atm.
Now i know these guides are somewhere but now that you mention it they do seem somewhat hard to find. ( on the app anyways)
But as for rolling back and then updating again via dload ( not TWRP) you need the rollback package and official firmware for your phone model.
Google and/or the guides section here should help you find those.
It should give you two zips containing an UPDATE.APP file each.
You need to put these on a folder named dload (one file at a time)on your sdcard( internal storage should do, too but no guarantees).
Create the folder if it doesn't exist.
Put in the rollback update.app in first.
Then power down and hold vol up+ vol down while powering up and it should flash the file.
Let it finish, boot up, put in the update.app from the firmware in the dload folder ( remove the old file) and repeat the process.
That should be it.
Also, you might be able to sinply dload the actual firmware from the test key build without rolling back but i haven't tried ( i think )
Should the dload process fail, you most likely have the wrong file in your dload folder, or multiple files.
I should mention that the rollback file actually brings you to a test.keys build. It's necessary to flash to full firmware afterwards and dloading the rollback file has always worked for me.
Personally i found that keeping the rollback update.app file for the rollback in the dload folder at all times is a good security measure. (besides the usual backups)

I assume since you rolled back you have a locked bootloader atm.
Now i know these guides are somewhere but now that you mention it they do seem somewhat hard to find. ( on the app anyways)
But as for rolling back and then updating again via dload ( not TWRP) you need the rollback package and official firmware for your phone model.
Google and/or the guides section here should help you find those.
It should give you two zips containing an UPDATE.APP file each.
You need to put these on a folder named dload (one file at a time)on your sdcard( internal storage should do, too but no guarantees).
Create the folder if it doesn't exist.
Put in the rollback update.app in first.
Then power down and hold vol up+ vol down while powering up and it should flash the file.
Let it finish, boot up, put in the update.app from the firmware in the dload folder ( remove the old file) and repeat the process.
That should be it.

can you tell me what rollback package to use? i tried "(FRD-L19&L09, from Android 7.0, EMUI 5.0 to Android 6.0 EMUI 4.1, C900B300, Western Europe)" and didn't work
If you have an L09/19 it should work. Just make sure to flash the rollback package first.
Otherwise since you are on a test key build already, you might want to try to dload MM directly or if that doesn't work, try a stock nougat firmware via dload.
You could also try updating with Firmware Finder via proxy

If you are on a regular version of MM, as I understand it, you can update normally, yes

I have read about this problem on another thread but the problem was poorly explained and i couldn't follow to the processes explained on the replies, so i have created another new thread regarding this problem, because, in addition to being very useful for me, it might be even more useful for people that are searching for a solution.
I will explain briefly the scenario before talking about the problem itself.
I recently (1d ago) got my telephone blocked because of a Hard Brick that i managed to overcome using
DC Phoenix, from which i installed Emui 4.1 and then automatically updated via the built-in updater to Emui 5.0
As before my hard brick i was on a more recent build, Emui 5.1 (B394), i searched on the internet and understood that my current Firmware, "NRD90M test-keys" is a test build (or something like that) which can't be updated with the built-in updater.
So, i want to ask, in order to avoid getting bricked again, if there is a way i can update to the latest Emui available for my device, as in the current state the build, in addition to being obsolete, is also unstable and reports some compatibility errors, E.G. error retrieving microphone service when sending audio messages on WhatsApp, ecc.
i have heard of a method consisting of rolling-back the device to 4.1 again and installing 5.1 via Dload, but can you tell me how to do it more in detail?
EDIT:
Problem solved by rolling back to 4.1 b131 and then updated from internal updater app
Thanks in advance,
Federico

I am in a very similar situation and unable to solve this. Could some one help in this?
I had unlocked bootload, TWRP and Root. I decided to unroot and lock the bootloader. So, by following the steps mentioned in a different thread, I could successfully flash Marshmallow B130 through Force Update.
Steps followed:
1. Flash Rollback package
2. Flash Full OTA (Marshmallow on B130) from Huawei website which flashed
Now, the real problem started while trying to upgrade to Nougat.
I tried downloading B350 firmware from Firmware Finder. After slow download, it installs fine. But, after reboot I face below problems.
1. The OS is very sluggish and crashes so often
2. The build number says NRD***-test keys
3. No keyboard installed, so not able to login to Google as well.
4. At this point, Factory Reset, Wipe Cache Partition, rollback everything fails.
I had to unlock the bootloader and again force update Rollback Package and then to Marshmallow B130.
Now, I am stuck with B130. I tried downloading B340 and B361 thru Firmware Finder. Both of them installed but with the same result. I mean No keyboard, Test-keys build, Crashes
My Honor 8 model: FRD-L02
What should I do upgrade to Nougat? I have no confidence in Firmware Finder method. Any help appreciated
It's EMUI 5.0.1 not 5.1, I think.
Hello.
I've read through the forums but am still quite unsure if i can restore my honor 6x from soft brick. It boots up but i get stuck in rescue mode if i have it charged Or it will just boot-loop if its not plugged in.
Im unable to use the DLOAD method. If i enter fastboot and use the three button method. I get put to the rescue screen. However i may be using the wrong firnware? Possibly.
Its a China version. PE-UL00 given to me from a friend, he said he had restored it to factory settings. So i wanted to upgrade the android kit kat to lollipop version. It was running emui 3. Kitkat 4.42. I believe updated the wrong firmware file through the local update method I download from firmware finder.
Basically from what ive read through the forums would i need to unlock the bootloader and flash stock firmware? . I have the information to acquire the bootloader key i believe and. I have downloaded honor multi tool and huawei multi tool, as well as adb drivers
I get confused as to which stock rom or. Firmware i should download or use. And i cant access the phone to see the build number. All i know is that it's. A China version. PINE-UL00. HONOR 6X. I do remember seeing
UL00_V100R001CHNC00B200 or similar when i was able to access the phone. But it also had custom at the bottom so i wasn't sure if it was a custom rom.
Any suggestions for a noob. Thankyou.

I downloaded dc unlocker, but it doesn't support the boot loader id for PE-UL00 honor 6x. Im still waiting on huawei for the bootloader code. I think k have to log in for 14 days consecutively? I keep getting that message when I try to unlock.
Also the firmware I tried to update it was PE-UL00C00361 OTA-MF from firmware finder.
I downloaded dc phoenix unlocker. Found the correct stock firmware to the best of my knowledge and the phone back to normal. After I was able to update to marshmallow through system updates.
Thank you anyway
