Rollback EVA-L09/L19, from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1

Hello !
I found on the Romanian Huawei page this package, used to go back from 7.0 Nougat EMUI 5.0 to 6.0 Loli EMUI 4.1.
UPDATE: for both L09 and L19
It contains a pdf with instructions.
Advice from other users: use an older version of Android 6 MM
I am not responsible for any bricks.

INSTRUCTIONS from the pdf file:
HUAWEI
EVA-LXX EMUI5.0+Android7.0 rollback to EMUI4.1+Android 6.0
Operation instruction
The instruction guides user to roll back from Android7.0 to Android 6.0
1) Roll back operation includes twice SD card update，only through intermediate package
EVA-LXXC900B300, like below：
2) Allow roll back to Huawei official stable release.
Precautions:
1. Make sure the current system version on your phone is an official Huawei version based on Android 7.0. If your phone has been updated with a non-official version, the rollback may fail and even cause unexpected problems.
2. Make sure your phone system version has not been unlocked or rooted.
3. Your personal data will be erased during the rollback. Be sure to back up all your important data beforehand.
4. Prepare a micro SD card with available storage space at least 8 GB.
5. Make sure the battery level is higher than 30%.
6. The rollback includes two local ROM flashing procedures, first from Android 7.0 to the intermediate package version and then from the intermediate package version to Android 6.0.
Step 1: Back up data.
Your personal data will be erased during the rollback. Be sure to back up all your important data beforehand.
To back up data to your micro SD card, go to Tools > Backup, touch backup, and follow the onscreen instructions.
Step 2: Update your phone to the intermediate package version.
Obtain the EVA-LXX intermediate package (UPDATE.APP) by visiting the official EMUI website or calling the customer service hotline.
Load the UPDATE.APP package to the dload folder under your micro SD card root directory. If there is no dload folder under the directory, please create one. (Do not load the UPDATE.APP package to the internal storage.)
When the phone is powered off, press and hold the volume up, volume down, and power buttons simultaneously to enter forcible update mode. Release the buttons only after the rollback starts. Do not operate the phone during the rollback.
Step 3: Confirm the intermediate package version.
When the phone is powered on, go to Settings > About phone and check whether the displayed version number contains EVA-LXXC900B300.
Step 4: Update the phone from the intermediate package version to Android 6.0.
Download an older version of Android 6.0 full package (UPDATE.APP) for the EVA-LXX from the EMUI official website. Load the UPDATE.APP package to the dload folder under your micro SD card root directory. (Do not load the UPDATE.APP package to the internal storage.)
When the phone is powered off, press and hold the volume up, volume down, and power buttons simultaneously to enter forcible update mode. Release the buttons only after the rollback starts. Do not operate the phone during the rollback.
Step 5: Confirm the system version and restore data( better not).
When the phone is powered on, go to Settings > About phone and check whether the displayed EMUI version is EMUI 4.1 and Android version is 6.0.
Go to Tools > Backup, locate the desired backup record, and follow the onscreen instructions to restore.

It's everywhere now. Here in Bulgaria too. So hard to go back. Wish HiSuite was better and just connect your phone and install stable version, something like iTunes. I am not so advanced on Android, recently switched from iPhone and really want to test the Nougat on this beautiful phone, but if it's bad I will have to buy SD card and do all this crap just to get to stable os... Ain't worth it.
P.S: What this part means "6. The rollback includes two local ROM flashing procedures, first from Android 7.0 to the intermediate package version and then from the intermediate package version to Android 6.0." What is intermediate package version?

it means that it's a 2 step downgrade.
first you flash the update.app in the zip attached (intermidiate package ).
then you flash your desired version of Android 6.
it's not that difficult. and you can do it from the internal memory also via the 3 button combo method

It worked with my L19C432 that was running L19C432B322. Thanks.

Confirmed that it works on L09C432 to, so it's not just for L19.

I can go back to 6.0 but I can not apply theme how to solve please help

Has anyone tried this with L09c636 or L19c636?

Since it's a C900 cust Rolleback it works on all Cust, C636, C432, C185 ..... etc.... L19 or L09 it's the same.

Wonderful news, thank you!

It doesn't work with me : the rollback of B300 to B182 failed.
EDIT : In fact, it didn't work because I didn't have enough battery...

Trying this now I'm L09 C432, what a ballache!

Still really hate this phone, well done Huawei :clap:

Did you found a solution? I am experiencing the same problem. After downgrading to Android 6 themes don't work. Also i've installed L19C432B180 and when searching for an update its saying its the latest version. I upgraded to Nougat from B182 wich was an OTA update and now i can receive it anymore.
I think Nougat did something to system partion and now after downgrade not everything its working properly.

I'm on L09C432 in UK.. and was considering upgrading..
Is 7.0 N That bad... Ive read its a Leaked version, which usually means Beta... but Ive read a few forums where people are rolling back
Would you recommend staying on B182 for now...

The official beta is quite good, but you can't get in the list anymore. From what i have read, the leaked one is not that ok. I recommend 182 for now
Sent from my EVA-L19 using XDA-Developers mobile app

I had a nightmare with up and downgrade last night. I thought i've broken my new phone but i've managed it to get it working again without any problems (themes also do work here).
What have i all done, for the reason someone else have troubles with downgrading.
Tip: Do not try to backup anything, it will most likely will make things even worse. Wipe and flash without later importing backups from different builds.
My phone: P9 (L19) DualSim
New phone, directly unlocked bootloader and removed OEM protection
Installed TWRP 3.0.2.0
Opened recovery and installed directly the BETA image for my L19
Until this point all works fine. BETA image is buggy, keyboard not working and freezes sometimes
Decided to go back to stock
TWRP is not working anymore, stuck in "Your device is booting"
Always running into Huawei eRecovery, where you can do noting. Repair always fails
Downloaded latest stock image for my L19 and tried the here suggested steps
Note: Before doing the "dload" flash you need to flash stockrecovery, as far as i know and other threads suggest it too
First Update.app flash (from the zip file here) worked fine
Second Update.app flash from the stock rom stuck at 5% and closed with an error
Hours of trying different things, all not working (Other TWRP recovery version with encryption support, wipes, resets, etc...)
Last try: Download an older stock image of my L19. Flash successfully done. Phone boots now into stock rom :good:
Locked Bootloader again (i guess it have been done by the stock rom flash)
Now i'm completely back to stock - Which is currently the best available rom for this phone, IMHO.
Conclusion: The most headache i got from downloading the wrong (too new) stock image. Trying an older one have solved my flash problems.

I found the same procedure to work. What really puzzled me was that the flashing of update.app "crashed" at 5%. I also tried all sort of solutions, with only new error messages as result.
The final solution to flash an older image was not exactly obvious

i will update OP. thank you for sharing

I tried 2 versions, still gives me errors. Could someone provide the exact version of the rom used in rollback?

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 ...

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

what should I do

I Have a Huawei mate 8 NXT-L29C185B190. Couple of months ago I rooted my android. With TWRP and unlocked bootloader. I by mistake formated my phone with TWRP and then all my data including the Huawei mate 8 themes and icons were gone. The icons were like the older versions of android(messed up). Just a minute ago I got an OTA update. So I removed my root by SuperSU and then tried to update it. But then it redirected me to TWRP. I didn't what to do so I rebooted the device. What should I do to install the update and get stock version? (The update is not installed)

SRK Tool

Before trying to update you might want to fix the problems of your device, get SRK Tool, root your device, then go to utilities and flash the HW Init folder, that should solve the themes and the icons problem, then flash stock recovery and then get and flash
L29 C185 B190 through the Dload method, only after doing all this you should take the OTA without issues (dont worry when you doad L29 C185 B190 root is lost).
You could also try to only flash stock recovery (using SRK Tool) and take the OTA but very much likely the theme and icons problem will still be there, if the OTA update works that is.

Oh ok. What is the hw init folder? Is it like some type of Huawei folders? And if possible can like provide a link on how to do it. I know about the flashing. Its just that I am really scared that my phone may hardbrick. I looked on XDA Developers for this stock firmware but found it on another website. But the thing is that I'm scared if that websites porvides false information

Dont be so scared!

The HW_Init folder contains the folder structure needed so the themes can be applied, it also contains the default themes which are lost when you format Data from TWRP, its a quick fix and the SRK Tool makes it easier for you.

About the firmware you found, if you have the link to firmware theres a way to check the changelog, pass me the link and ill check it for you.

Ok, I rooted my phone(Huawei mate 8 NXT-L29C185B190)(L29B) using the SRK tool before and I did it again. So for the hw init folders I should check it on the internet right? Do u know how to flash it?

This is the website that I found for my stock firmware
P.s thx for you help. I am a noob when it comes to this

Open the tool (SRK tool) then select the option 7-Utility then select option 12 and then 1(mate 8), once the process started be aware of your devices screen, it should ask for root permission for an ADB shell and you have to grant access otherwise it wont work but dont worry you can try manytimes untill you get it right, your phone wont explode o anything like that If all went well , youll be asked to press any key at the end to reboot your phone, after reboot you should be able to apply themes and icons like usual.
About the firmware, this is the link where its being downloaded: http://download-c.huawei.com/download/downloadCenter?downloadId=91645&version=357954&siteCode=pk, seems like its directly from huawei server, you could download it to your PC and explore it with firmware extractor or you could just flash it throught the dload method, if is not right for your phone it doesnt flash it.

The firmware is legit! its straight from huawei, if you download it and extract it you will see a manual from huawei telling about the update and whatnot, its safe to push through Dload.
Your welcome and good luck!

Oh thanks man just one last question before the start the process. So ehen you flash the stock firmware won't the stock recovery automatically be applied and if not is it necessary to flash stock recovery first then flash stock firmware? And theabove firmware link which u put, idit the firmware for NXT-L29C185B190 ( THE 64 GB 4 GB RAM MOCHA BROWN)
And I also heard if it is not the right version for your phone it can hardbrick it that why I am just making sure about the firmware. And when before I flash my firmware should is it need to factory reset the phone

Your welcome.

For the dload method you dont need the stock recovery, I have just learned that the E recovery its always inside the Mate 8 eventhough you have a custom recovery, so you just need to place the update app inside a folder called dload, the folder should be on you external SD card, then what you do is turn off your device and then press and hold volume up, volume down and the power button at the same time until you see a screen telling you that is checking the firmware, if the firmware is correct then E recovery will do its thing and flash the firmware, the stock recovery will be included, you will loose root and the bootloader will close again.
Or you could flash stock recovery just to be safe and then do the upgrade process (dload), you can do that with the SRK Tool, just be sure to install a stock recovery acording to your version of EMUI.
About the firmware, I cant say, I do no own that variant, thats for you to find out, google is your friend!
About bricking, you can only do that if you downgrade the wrong way or if you flash an incremental OTA file incorrectly and even then theres many ways and tools to bring the mate 8 back to life.
My advice is that if you are goin to be messing up with your device, always do it whith an open booltoader, always back up your base firmware right after opening bootloader, back up your cust, oem info and custom bin and always check that developer options are enabled and that Enable OEM unlock and USB debuggin optiond are enabled as well.

Just realized this is in the wrong segment! @Jerry77827 Please read the forum rules before posting anything in XDA, dont be impolite!

Any possible way to unbrick my phone?

Hello, guys. I bought two of these phones. BLN-AL30 VERSION is the one that I was using for a while. I tried to unlock its bootloader and it was a complete success. I remember that my phone said BLL-L22 in its about device section and not BLN-AL30 though. I proceeded to install TWRP and rooted it, I also backed up all the partitions so I decided to go for the elite version (TWRP, for I wanted to install their room). Everything was ok. I installed the elite rom which I thought was cool and I used it for a while. Then I decided to switch into slim ROM. I had made the proper back up also and still have them files. I backed up everything because I realized the elite ROM asked for a complete wiping. The next thing I realized was that my phone wouldn't be able to install the slim rom because I had this error:
Unable to wipe vendor /vendor command not allowed.
It also happened with product and version partition. And sometimes it said unable to mount /vendor. (The same for product, version)...
Now, I can't install any other room because of that. And I have downloaded many update.app files to recover and heal my phone as stock but it seems impossible. I have bought another honor 6x and it's coming the next month because I loved this phone but also because if bricked but unrecoverable I'd like to have its parts in case of some repair needed. Is there anyway to recover it? it's so sad. I never thought elite rom would do that to my phone. I assure I followed every single step from its thread. Thanks in advance. Hope you can help.

try to formate data then go to main main screen reboot to recovery now wipe everything. if it is not working then try previous version of elite TWRP or Berlin TWRP. if nothing works then u need to do dload. but u r saying dload is also not working still u have two solutions. download oem info of another region and flash it via TWRP u can try oem info for bln-l22c675b340 https://forum.xda-developers.com/honor-6x/how-to/guide-debranding-to-india-variant-bln-t3679402 now Google for bln-l22c675b340 firmware download it then unzip update app file. now Flash oem info file in TWRP then using sd card flash update app by pressing 3 buttons. this time it will install for sure. if oem file failed to install then extract the oem file then download srk tool put both files in restore folder connect your phone in fastboot restore oem info will work for sure. there is no way to brick honor 6x lot of rescue methods available if this fails still you can use hwota8 method to upgrade oreo.

Thank I'm going to try that
Where can I find the Oreo update thing?. Thanks

[NEED HELP] Unbrick Honor 6x

I've somehow bricked my 6X.
I have an EU version successfully debranded to India variant BLN-L22 and upgraded to EMUI 8.0, unencrypted and rooted with Magisk.
Something went wrong during the flash of AEX for hi6250 devices (which is reported to be 6X compatible ): I was mainly stuck in a bootloop except for two times when the phone booted, but internal storage wasn't recognized properly (in settings I was able to see the correct percentage of available space but in default file manager I wasn't able to access it and also downloading files to internal storage was impossible, as if my it was full - which isn't true since I was able to move file there through TWRP file manager).
At that point I was pretty pissed, I've forced fastboot and used update.bat to flash stock Oreo again and here things screwed up.
I took a full TWRP backup before experimenting with AEX and copied it to my pc; I'm able to push it to internal storage through adb, but then TWRP isn't able to restore it, dunno why.
My phone is in these condition now:
fastboot is available, commands from pc are working here
bootloader is unlocked
FRP is unlocked
I have a working TWRP recovery (askuccio 3.2.3) which I can access and use; I'm able to replace it with Elemental 3.2.1, with the one provided in the "update.bat" thread (which is another 3.2.1 version) or with stock recovery
if I replace TWRP with stock recovery and boot into it, it shows the update screen and it freeze at 5%, then reboot; no factory reset option there
when I'm into TWRP I can push files from pc to internal memory through adb
pretty sure my phone is still decrypted, dunno if it's still rooted tho
eRecovery is gone
I have no idea how eRecovery gone missing since I never touched that partition; trying to flash ERECOVERY_RAMDISK.img through fastboot using "fastboot flash erecovery_ramdisk erecovery_ramdisk.img" which fails (remote: command not allowed) and "fastboot flash recovery2 erecovery_ramdisk.img" which fails (remote: partition length get error) as well as through Multi Tool (the size or path does not match the file system markup); if I try to boot into eRecovery I get error mode screen: Func NO : 11 (recovery image) Error No : 2 (load failed) and I have no idea how to try to restore it in another way (pretty sure all I need is to factory reset through it and then reflash the firmware for unbrick my phone).
Atm I've tried only Multi Tool: I can successfully flash everything in the unbrick section but it doesn't solve my problem (guess it's due to my missing eRecovery).
I still need to try Image Download method (which I would like to keep it as last resource since it requires to disassemble my device and since I have a working fastboot and TWRP), HuRu and dload (I don't have a micro SD big enough atm, only 2GB - dunno if it can can work from internal storage the same).
Thank you for any help.

I would say the safest option you have is to restore to Nougat via dloading the b340 image which you might have used for debranding. You should be able to restore easily.

How do I do that?
I mean, flash OEMINFO and Custom Bin and then dload method as per debranding guide or HWOTA7, since I'm on Oreo/Emui8 now?

You already debrnaded to Indian version and then updated to Oreo right?

Exactly. I was on BLN-L21 Nougat (EU), debranded to BLN-L22 (Indian) through fast method (flash oem and cust bin, dload, update through system update) and then upgraded to Oreo through HWOTA8_BLN - script method.
Multi Tool list my device as BLN-L22 8.0.0.510(C675).

Just dload b340 indian variant. You should be fine

I restored my device countless times with HuRUpdater, the best tool I used on Huawei devices. It always go fine, but a microSD of at least 3GB is required (files to flash are usually 2,70GB). Probably the device won't boot with stock recovery because as you pointed out, it needs to format first before booting since that you was decrypted. HuRUpdater needs to be executed from microSD because it flashes files from there to internal storage, so flashing from there isn't allowed due obvious reasons.
Looks like you'll need to dload, as my friend Shashank1320 said. You need to start again with a fully working system before going elsewhere and at the moment things look bad. The rest is always obtainable again (TWRP, ecc.)

dload doesn't work, I guess it's because I miss eRecovery.
If I hold vol+ vol- and power my phone boot into TWRP; I've tried replacing it with stock recovery but it freeze at 5%.
Any way to flash eRecovery from fastboot or as a zip from TWRP?
Gonna get a SD and for HuRu if I won't be able to solve it differently.
Edit: managed to boot into dload screen, but it states "software install failed".

That message is because the package you picked is wrong. What was your build number, BLNL22C636B510CUST..? (Don't remember if this is the build of first Indian Oreo build dated June/July 2018)

I'm not sure since I don't have my device at hand atm: yesterday I got a 16GB SD and tried with HuRU but without success (trying to flash the zip returned me an error with every version of the package), so I contacted the assistance since I still have some months of warranty. I've tried to restore it as stock as possible before handling them the phone so I hope they won't make me trouble and fix it :angel:
Anyway I've always used firmware provided by shashank, both to debrand to indian variant and to upgrade to Oreo, so you may recover build number from those threads for scientific purposes!

For me HuRUpdater never failed a shot, you just have to choose the correct build and rename the zips as per instructions in OP. Usually the zips are three, by the way. "BLN-L22HNC675CUSTC675D1B510 (8.0.0.510)" is the correct build number for Oreo India, if you use HuRU with the three zips included in this build the successful flash is guaranteed (done it personally many, many times).
Now, if you contacted assistance and you can take advantage of remaining months of warranty wait and see what they say. Good luck!

Reflash EMUI 8 with Hwota 8, but first wipe data partition with TWRP.

Wait: wiping /data with TWRP makes it visible through custom recoveries since that it removes encryption, but when you flash whole EMUI 8 on system stock recovery_ramdisk is reflashed on the recovery partition too, and it forces to reformat /data before booting because if not it'll say that OS is seriously corrupted bla bla bla... EMUI 8 doesn't have to run encrypted?
By the way HuRU is faster, easier and leaves bootloader unlocked.

Nope: don't get me wrong, but I'm here since 2012 and I'm pretty used to this kind of stuff.
I can assure you I haven't picked wrong packages nor any other noobish error: in fact I wouldn't even had to post here if I had encountered just some standard problem lol... my device wasn't fixable through usual ways, or else I would have been able to

Just heard back from assistance and they are waiting for a new motherboard since there was nothing to do, good to me I was still covered by warranty.
Now it would be nice to know what screwed up my device so bad, since I hadn't any problem till the flash of AEX for hi6250 devices (so 6X compatible) and even in the case it wasn't flashing a wrong rom has never fked up a motherboard in my experience, but whatever.
My only trouble is I'm pretty sure I won't be able to unlock bootloader when my phone will be back, now
Also, thank you to everyone who tried to help!

try this
i had issues also until i found this step by step, i named everything just as he has pictured and made sure to just add the .zips all 3 needed, got correct FW from FW finder and also be sure to put the actual HuRuUpdater.zip in the same folder with the FW files and name the parent folder just like the pic on post shows...poof working stock FW and did not relock my BL....Honor 8 FRD-L04 reverted from no OS to stock 7.0 on EMUI 5 https://www.getdroidtips.com/hurupdater-tool/#comment-109621
