[TUTORIAL]How to update EVA-L09C636 (Asia-Pacific) model to B361 (EMUI 5)

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.

Guide: Huawei Rollback and firmware version change guide; Back TO BLN-L21C185

To get to Andorid 7, I used Firmware finder method as send to updated and flashed "BLN-L21C432B342" Firmware finder send to update method.
Most of the updated using from: http://hwmt.ru/oth/HWFF/info/view.php?find_model=bln but it does not have second update package which is needed to flash to get the updater app and others.
Guide to get back to BLN-L21C185
DIAL: *#*#2846579#*#*
GO TO : 2.Veneer Information >
1.Version info >>Manufacture Information is your actual model: (my is: BERLIN_L21 i.e.: BLN-L21)
Scroll to end there will be current version, this is the version you need to use to roll back.
My was Bln-l24
1. So i downloaded the BLN-L24 USA Roll back package.
2. And downloaded the BLN-L24 Latest Andorid 6 update. (BLN-L24C567B110)
both FROM: http://www.huawei.com/usmobile/consumer/support/downloads/index.htm
Above are flashed using Sd card dload method and they worked. 1st flash roll back package and let the phone start to normal than again flash the android 6 package "BLN-L24C567B110".
Now you are back to BLN-L24 but setting is showing BLN-L110.
Anyways now you have updater app back so use the same method to get back to BLN-L21C185B131 (android mm).
I did not roll back and instead flashed BLN-L21C185B342 as it is available now, using firmware finder send to update: https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146 and bingo back to C185 andorid 7 with updater app.
FACTORY RESET YOUR PHONE IN THE END.

My phone was on BLN-L21C185B131. I installed firmware finder on my PC and downloaded BLN-L21C185B342 from there. From update.zip extracted update.app and installed using dload method. At the end of the update the message was something like "update failed". Now "System update" is missing in settings, factory reset is not working properly (it resets the phone but there is a message during the reset that Factory reset failed) and the build number is "NRD90M test-keys".
Please advice how I can fix it. Tnx

You should have used the method sent to updater.. anyways you have to flash the second half part of it.. "
update_data_full_BLN-L21_hw_meafnaf.zip"
I am uploading the second part which you should be able to flash using dload to get the complete update with updater working.
Will share the link soon.

How is it

What about themes app is it work and are there a rollback package if you didn't like it

First of all thanks for this wonderful post, you did a great job.
Don't mind it but you have made a great post, without a great title/name, so i suggest you to modify the title of the post, these kind of posts are very helpful for people like me and others but most of the people out there use google to search help they don't know the XDA, so if you modify and give a better title to your thread it will be easily found by searchers.
Lastly what is the main difference of numbers after BLN-L21 i.e. mine is L21C185 on the about phone but the hidden info *#*#2846579#*#* and Veneer Information and version information says at Manufacturer Information BERLIN_L21_VN1 AP Version is L21C900B131_SYSTEM while the Parameter Version says C185, NOW what is my devices real name and which firmware should i be downloading for my device if i want to roll back to 6.0.1?

Hi, i understand if information is not easy to find it of little value suggest me a name and i will change it.
If you are on android 7 you need to first download the roll back package of the "version component version" showing in veneer info and flash it, then flash the same version android 6 latest package. Then use the firmware finder send to update method to get back to your real version either andoid 6 or android 7 as your prefer.
I have seen c185 is used used for middle east market.
"Manufacturer version" is your real device variant. (your need to download this to roll back with the roll back package if your are on android 7)
"version component version" is your current installed firmware Version.
Ideally they should be same but if firmware finder is used to install different variant firmware, to get to a newer android version or for some other reason than these both miss match.

Well, I am sorry but you again jumbled a lot of things just in some lines which didn't help me.
For your thread i would suggest the name "Honor 6x L21 downgrading/going back to B130 or B131 or B120" whatever file version you used to go back to 6.0.1.
As i have said before, i am have an Honor 6x BLN-L21C185 which is now on B131 stage of update but i want to upgrade to B342, while Phonenix1024 on this https://forum.xda-developers.com/showpost.php?p=71578919&postcount=134 thread suggested me to role back to B130 and then update to B342 via Firmware finder. What is your suggestion and what is your experience BTW.
I am sorry again if i was a little out spoken!

@Tangra , It has been suggested by some guys on this thread https://forum.xda-developers.com/showpost.php?p=71578919&postcount=134 , that we should go back to B130 and do not update to B131 but install firmware finder and directly upgrade to B342. So it was your bad luck that you are facing this but as Omair said you can flash his file or just download the B130 for your device model and follow the dload instructions to give a new life to your device. God bless you.

Well your question is more correct now.. So here is the simple answer.
No need to go back to 130 ...I also upgraded from 131. See my first post and update using firmware finder but using the method send to updater see the setting of firmware finder as you will need to do some proxy setting.
For the second file question as I explained in a reply to another member its a second part flash file to upgrade to android 7. Only if you upgraded using dload method.
The file is for bln-l21c185.

@talvigi its a second part flash file you need to flash in order to get full functionality on android 7. This file is only needed if android 7 update is made using dload. This will also give your correct version in about and updater app. If update is made using firmware finder sent to updater method than this file is automatically downloaded and flashed in updating process. I got this file from the updater folder.

Oh, no yaar, @Omair.anwar I have already formated my device this morning, because it was download the full update file send by firmware finder to my updater.
But i am still on B131, so according to you i should directly upgrade to B342 and i shouldn't go back to B130. BUT you said you had problems in B342 like no update options etc, may be this was just because you upgraded from B131?
@Omair.anwar if you live near by me in Pak please answer me that in the firmware finder should i choose the FullOTA-MF-PV size 2.352GB? my number is zero three two double zero two six one double six zero. Thanks

I am not sure.. it should work fine if you Will use firmware finder with "installation via system update" and "view OTA updates" in setting.
If you want make sure, then after updater had downloaded 100% go to internal storage there will be a folder named something like OUC and see in its sub folders there should be two files one named update.zip and another named like "update data full".
I had the problem because I flashed different version firmware.

Hi ! i have one question
After RollBack package flashed can i flash directly BLN-L21C432B130 or i flash the BLN-L24 Before ?????
I have my answer i can't flash directly my french firmware ...
It's the brothel to return to Android 6.0 compared to nexus or samsung devices XD i like challenge
Rollback Package For BLN-L21 ?????? : http://www.hihonor.com/fr/support/software-list/index.html (no tested because i have flashed the rollback package of BLN-L24 .... too late for me )

omair.anwer said:
Well your question is more correct now.. So here is the simple answer.
No need to go back to 130 ...I also upgraded from 131. See my first post and update using firmware finder but using the method send to updater see the setting of firmware finder as you will need to do some proxy setting.
For the second file question as I explained in a reply to another member its a second part flash file to upgrade to android 7. Only if you upgraded using dload method.
The file is for bln-l21c185.

Thank you for the link. I unzipped "update_data_full_BLN-L21_hw_meafnaf.zip" and dropped the content in dload folder on SD card. Flashed from Engineering mode menu and everything on the phone works correctly now.
I was trying to locate this file "update_data_full_BLN-L21_hw_meafnaf.zip" by myself with no success. i'm curious how did you find it and is there a link for this file somewhere on hicloud servers. I see that for EU version off the phone this file is available for direct download from there.
Anyways, you did amazing job and your post will help many people I guess. Thank you!
P.S. I noticed after I posted my remarks that you've got "update_data_full_BLN-L21_hw_meafnaf.zip" from your Updater App folder - great job and hopefully somebody will find the link for direct download from hicloud servers

Hi if you flashed Bln-l24 roll back and it worked than you can still flash bln-l24 android 6 package and after that use the firmware finder with correct settings to get back to bln-l21.
See pic attached for settings and read my very first post too.
I hope I understood your concern well.

See pic attached for settings and read my very first post too.
I hope I understood your concern well.

so.. i'm here, seeking help from experts : ) i've tried to search the entire forum but couldnt find a solution.
I would really appreciate a step by step guide with links because my main problem is finding the right versions for me over the net.

Hi, if you are rooted edit the build.prop and change test-keys to your version

Can you share yours /system/build.prop ? I've a lot of test-key properties to change
PD: not everything was working. I just made some changes and now printing service works. Only updater are not working ^^

OK. Found a solution
I'm now on kangvip rom, I used the tool from this thread: https://forum.xda-developers.com/mate-8/general/huawei-mate-8-downgrade-android-7-0-to-t3530999 downgraded to B320 and then installed KANGVIP. works 100% just follow the thread.

I'm also curious.
Isn't there a official Nougat update to the Huawei Mate 8 available?
I have been stuck on the test-keys for a long time ( since the release ).
I have unlocked bootloader and I'm kinda unsure how to use the FirmwareFinder and FirmwareProxy.
If someone have a good step-by-step guide i would be greatful to follow it.

As i mentioned, use the tool in the thread i gave. Just flash the tool using dload method and reboot your phone. now flash a rom of your choice (stock) using dload again. And that is all, no more test-keys.

Maybe you have somethink to downgrade AL10 to emui 4.0 or 4.1 from 5.0 (nrd90m test-keys) (dload method don't work).
I will be very grateful

Flash stock firmware ( try b386 or Android 7.0) in twrp (this might work)
Or
Press and hold volume up and connect to charger or laptop. It will enter erecovery. Try to download the firmware using Wi-Fi
Please try the first option.
I think I gave you detailed steps in another thread on everything . You can try those steps.

Download Full Package (system update)

I noticed some annoying bugs in Emui, so I thought "hey, why don't reinstall the OS" I tried it over HiSuite but it didn't worked out. After that i noticed the "download the full current package" button in System update. The button does nothing, is this normal? I'm just confused asf, the Mate 9 is my first device so idk. I also noticed that Huawei isnt offering the full roms anywhere where the public can find it easily. OnePlus & Samsung did a better job there... Is there even an easy way to reinstall the OS or update it manually?

Yes. It is normal when System Update doesn't download "full package", cause it checks current and choose not download same version.
And yes. Huawei doesn't offer full ROMs in easy places. They post all ROMs on HiCloud (Huawei Cloud Resource) silently. In a few cases they can post ROMs on Huawei official site, but it is too rare.
Huawei thinks that no necessary to told everyone that new version is coming, cause they are using method with OTA updates.
And no. There is no easy way to reinstall OS or update manually, but with some exceptions.
Current free method uses modified recovery to force update. It requires bootloader unlock procedure (unlock forces factory reset procedure). Additionally method requires some knowledge how whole process is running.
There is paid method also. It is easy in general and you should DNS setup only. But a few percents are choosing pay for service what helps people to install free ROMs.

Are you serious ??
@idealfall1
The easy place to download firmware is firmware finder on Google play store they have all Huawei firmware for all model...
Or we have this site
http://hwmt.ru/oth/HWFF/info/view.php?find_model=
Find your model number and download it.
And for finish we have a very very easy way to force re-installing firmware without root or flash recovery or paid solution or unlock bootloader... It's the 3 button method !!!
Create a folder in external SD card, call him dload and put firmware (update.app) in, turn off your phone press volume down + volume up + power in the same time and voilà
Sorry for my bad english

Huawei Firmware Finder is private project of enthusiasts. They don't host any firmware and only help people to find ROM in HiCloud. But question from idealfall1 was why Huawei isnt offering the full roms anywhere where the public can find it easily. Other manufacturers do it.

Do you have Mate 9? Did you try install something with 3-button method? I tried many times. It is not working.
In case of Mate 9 Huawei added special tag "UPDATE_ONLINE" in rom. And most roms are with this tag will not install via 3-button...

If you are right, so it is very good news!
5 or 6 months nobody can't install roms via 3-button. There are only 3 service ROMs with tag "offline_update".
What exact version do you have? I will download and check for tag.

Ok, conclusion time. Mate 9 users cannot update via 3-button because of this special flag/string. Does the firmware finder work? It's technically an online update, right? I'm a little bit confused... Firmware Finder found for me some FWs from june... Can I install them? Sorry I'm not looking through this mess xD

When I buy it they are in b126 version and upload on b138 but if the 3 button method don't work for update firmware like you say may be can work for him because he want flash the same version of firmware, are you fellow my reasoning ?

If you're using FF, you must know that it forces ROM to system update.
Workflow is simple:
1. Find ROM
2. Force to system update
System Update will download ROM by self, like update is coming from Huawei officially.
But Huawei prevents this trick on very new ROMs and additionally checks for authorization.
In it's turn, FF can check ROM too, tries to reproduce Huawei's routine.
So, if you want install latest rom, you have to use method with modified recovery to force update.
If you want install old ROM - force update via FF.
P.s. We are all huaweied

Yeah. Good idea.

Three button reset does not work with the Mate 9.
It just doesn't.
You can only factory reset if you're on stock.
That applies to ALL stock firmware as far as I know.

[Honor 8] update from NRD90M test-keys 5.0 to 5.1

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)

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

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.
