[HOW TO]Go back to EMUI 3.0 from CM11 - Honor 6, 6 Plus General

Hey guys!
I recently decided to try CM11 for this awesome device and I was extremely impressed by it.
One foolish thing that I did was that I didn't create the nandroid backup of my EMUI 3.0 version B380 rom. So, I tried to revert back using the 3 button method(creating dload folder and pasting update.app).
But for the life of me I could not get it to work!! I tried following
1) Straight away pressing 3 buttons but it failed.
2) installing stock recovery using multi-tool. Tried all recoveries (for my l04) still failed.
3) removing ext sd and creating dload in internal. But it couldn't even find the update this time!
So, I was browsing through forum and came across this post thanks to @Julsen1985 , @ thermalboyz
1) Use "B608" and flash via fastboot: (Extract using Huawei Update Extractor) Put into adb folder and manual flash from CMD.
- fastboot flash recovery RECOVERY.img
- fastboot flash system SYSTEM.img
- fastboot flash boot BOOT.img
- fastboot flash cache CACHE.img
- fastboot flash cust CUST.img
- fastboot flash userdata USERDATA.img
2) Reboot phone

Just download the B370 version from OP of cm11 and follow the exact procedure mentioned above. When you open command terminal, give command "adb reboot bootloader" and start flashing
U might have to factory reset as it shows incorrect user available memory. Then u may proceed for the B380 incremental update.
Also thanks to @worstenbrood for extractor and @VirusPlus for multi-tool .
Hope this helps!

The flashing with 3 buttons, after installing with fastboot, takes forever to load at the end. Is it just stuck or is this normal?

It worked once for me, while going back to stock from L01 firmware.
I just restarted to fastboot and did the "unbrick" option with Multi-Tool. After that, it just rebooted straight to EMUI 3.0.
Got it rooted with stock recovery now.
Thanks for your tutorial!

The Multi-Tool also guides you through the whole process, after "unbricking" , so it's kinda noobfriendly. After that, 3 buttons should work normally, I used the 3 Buttons before, so it just rebooted to EMUI, because it only rewrites BOOT, SYSTEM, RECOVERY and the CUST partitions.

as I understand ..... to return to EMUI 3.0 from CM11 in my honor 6 (H60) L04 have to put through fastboot rom honor B608 (H60) L02 .. ??
It's either that or misunderstand the steps ?????
EMUI try again but I can not do it ... always gives me error with vol + vol - and power

You don't have to go through B608, just download B370 and extract all *.img and reflash them with fastboot.
I did the "unbrick" option with MultiTool and after that restarted with vol-,vol+ and power to flash it from sdcard via UPDATE.APP.

I'm sorry I wasn't clear enough. If u have l04 version, then u have to download the b370 version. The quote was from a different post by a member.

I did miss as you say with multi-tools and perfect.
many thanks for the cooperation:good::good::good::good::good:

My L02 don't seem to accept any rom files i flash over usb after going back from miui to stock if you would have a look on my thread and point to the missing element that I can't seem to figure after working over 20 hrs on the phone trying to revive it

[GUIDE Step-byStep]RETURN2STOCK/UNBRICK/UNLOCK/ROOT] e.g. STUCK AFTER UPDATE

How to unbrick or get back stock on your Huawei Mate 8. There are many reasons why you would want to do that.
In my case my device (AL10) was stuck at "your device cannot be trusted" after updating from B180 to B321.
First I got to thank acer73 for his software. ajsmsg78 and Kris Chen for their links to the right ROMs.
Also thanks to DarkSilentSC for his help, especially with the L29, great support.
He has a L29, which I don't have, so I'm glad he provides help with that device.
This worked for me on my AL10 to get it back on track, should work on other models too. Just have to find the right ROMSs as according to your model. However, I am not responsible if this does not work for you or if it bricks your phone even more.
And remember: don't forget turning on usb debugging whenever you can!
Unbrick (return to Stock)
1. Find yourself a stock ROM.zip according to your model and extract from the zip the update.app (I used one from a B172 (AL10) Stock ROM, I was running a B180 custom ROM, it worked.)
2. Download the Huawei Update Extractor http://forum.xda-developers.com/showthread.php?t=2433454
3. Extract boot.img, recovery.img, system.img and cust.img with the HuaweiUpateExtractor from the Update.App you find in the ROM to somewhere where you can find them easily
4. Head over to http://forum.xda-developers.com/mate-8/development/rayglobe-italian-knife-t3295526 (You can also do it with fastboot commands, but Acer73's tool makes it easier)
5. get yourself the Italian Knife (btw you probably have to turn off your anti-virus program), extract it in a directory on your PC and start Rayglobe_knife.exe
6. Put the images you have extracted into the folder Unbrick (same directory where you extracted Rayglobe Knife in). The folder was created after you started Rayglobe_Knife.exe
7. Boot your phone into bootloader.
8. In the Rayglobe Knife tool choose Unbrick and choose the option where it says you have placed all the images in the unbrick folder.
9. let the magic work. The phone will restart and it will probably take 15 minutes, make sure its charged enough.
After all that I quickly updated to the latest Stock ROM version, in my case B321, which you need to do if you want to flash later a custom B321. See second post if you want to do that as well or continue with unlocking the bootloader.
Now lets get the bootloader unlocked (for some reason mine was still unlocked)
1. Get Minimal ADB https://www.androidfilehost.com/?fid=24521665358595410
2. Hopefully you still have your unlock code (cause you need it otherwise it won't work)
3. Put your phone in Bootloader Mode (Press & hold power and volume down)
4. Extract Minimal ADB zip and run command.bat
5. Type <fastboot oem unlock xxxxxxxxxxxxx> (where xxxx is your bootloader unlock code)
6. Done
Now lets get twrp set up
1. For that we need minimal ADB again
2. Headover to http://forum.xda-developers.com/mate-8/development/recovery-twrp-huawei-mate-8-t3298567
3. Download TWRP according to your EMUI (For B321 it's EMUI 4.1)
4. Place the image in the directory of the Minimal ADB
5. Rename it to just twrp.img (not necessary but simplifies things)
6. Put your phone in Bootloader Mode (Press & hold power and volume down)
7. Run command.bat
8. Type <fastboot flash recovery twrp.img>
9. Then type fastboot reboot
10. Now you can hold volume up and power until your phone boots into TWRP
11. You need to format data (you'll lose everything on your phone)
12. Done
Remember: don't forget turning on usb debugging whenever you can!
!!!FOR L29 scroll down to DarkSilentSC's instructions!!!
After unbricking I quickly updated my AL10 to the latest version, in this case B321. Should work with all B3xx
1. Head over to Kris Chen's thread (this I used for the AL10)
http://forum.xda-developers.com/mate-8/development/rom-verison-t3324164
Or ajsmsg78's (also AL10 and L09)
http://forum.xda-developers.com/showpost.php?p=66776194&postcount=58 to get the Stock B321
2. Download the ROM and after downloading the zip file, extract update.app from it. Copy the UPDATE.APP to the internal memory of your HM8 in a folder called - dload (you may have to create it). Then press [volume+]+
[volume-]+[power] together to force the update.
3. Voila B321
-----------
!!![For the L29 you should try DarkSilentSC's instructions, which you find below or in post #54 on page 6 http://forum.xda-developers.com/mate-8/general/unbrick-updating-to-b321-t3375934/page6 don't forget to hit thanks!!!
1. Start from stock B170 firmware with TWRP ready
2. Extract BOOT, CUST, RECOVERY, SYSTEM from B321 UPDATE.APP
3. Add firmware .zip file (which contains META-INF folder and UPDATE.APP) and place it into internal storage
4. Make sure internal storage data is fully backed up
5. Delete All Accounts in Settings
6. Go to Recovery, Wipe Cache, Delvik Cache, Data, System
7. Flash that .zip file! (Getting errors is okay at this time) [This is what I didn't do before!]
8. Boot straight to bootloader
9. fastboot flash boot, cust, and system
10. let it boot. Let it proceed with encryption process in chinese and fully boot into EMUI
11. NOW I'M AT EMUI 4.1!
12. Reboot to fastboot and fastboot flash insecure_boot and flash TWRP
13. Reboot to recovery (TWRP) and then flash whatever rom you want to place in!
14. Enjoying it!
Great, was looking for details instructions like that, was stuck at cannot be trusted screen

BTW I debranded mine too with Acer's to international.

But you first used different ROM images to unbrick and then tried to update to B321.
really sounds as if your file is corrupted. Would try to download it again

ok i will try tommorow......thanks for help by theway the phone booted but if i flash recovery for root no boot.... very strange....sometimes aloud to flash from boot some times no ohhhhhhh(((
Or something no correct with huawei extractor..... Can you provide extracted files?
Thanks in advance.
So I unbricked with B170 and then tried force flashing B321. My first attempt at flashing B321 ended up getting stuck at 5%. Tried flashing again and it said it was incompatible with the current firmware version of my phone. Any ideas on what I should do next?
Edit: Nevermind. I mistakenly copied the UPDATE.APP from B170 to the dload folder instead of the one from B321. lol
Now on B321. Thanks!

Don't know which ROM you used to unbrick.
But seems that you used an B321 if that worked for you and you have no problems then that is great.
Could mean that wet can unbrick straight with the most current ROM available. If someone else could confirm?

hello, my phone is still stuck.. i tried other cust/system/recovery/boot from other update.app, but its still stuck at: your device has been unlocked... im on l29
Have NXT-L29, downloaded stock L09 file from posted link, placed UPDATE.APP into 'dload' folder which I created, but still hanging at 5%. What to do?? Exactly where do I create this 'dload' folder? Just at 'Internal Storage'?

Bootloader has to be unlocked. You can unlock best with DC unlocker, it's fast and only costs around 5 dollars.
Unless you already have your unlock code then you can unlock following instructions see my first post

What are you trying to do? Unbrick or update?
The folder has to be created in internal storage

No fuss debrick/restore your Mate 8!

Whatever you did to brick your device!
Whatever crazy thing you did to make this beauty a brick!
Next time, please don't waste time and money (dc-un...)
:crying:
First relax, take a deep breath in and smile. This method restored few phones and can be tried on every Huawei phone.
Second, hold volume-down+power and connect USB via PC. Means enter "bootloader"
Then pick up any old stock firmware of your region from this thread
Third unzip and rename folder to suit your model.
Fourth FASTBOOT.EXE FLASH ZIP UPDATE.APP and take a cup of tea or beer. Let all the error messages pass of.
Fifth, remove your ext_sd card and copy this extracted folder into root directory.
Sixth FASTBOOT.EXE REBOOT
It won't boot but will surely go to recovery, factory reset. Reboot.
Seventh, here is the main thing, hold volume-up+power till recovery shows updating
Eight, allow to update and get into the normal mode.
You will get your HUAWEI MATE 8 working in mint condition.
If this works, press the thanks button and rate this thread 5 stars.
All the best.

Another simplistic method if you are able to boot to your working rom.
2846579
Manufacturers port
Check your region
Then fastboot flash recovery recovery.img of existing 4.1 or 5.0 Rom.
Reboot.
Sdcard dload
2846579
Sdcard upgrade
And you are back to stock.
Do whatever you want to do, mate, but dont flash nougat rom this month!
Thanks. Will come in handy.
Think for yourself. Question authority.
This method also locks your bootloader without a trace of relock bootloader

Buddy, I had a tough time to roll back from nougat to my own firmware because of local power cuts affecting the process and I bricked.
I logged in DC account and even downloaded Phoenix software but thought let's try.
Aloha! I was successful
Had few gulf sets lying as bricks at my friend's shop and tried in those and they also booted up.

Exactly! It doesn't flash but the bricked locked phone can be rebooted without issues.
Hi there! Thx for the instructions but unfortunately it's not working as intended.
After the Step FASTBOOT FLASH ZIP UPDATE.APP i get this output: see attachment.
Then the device reboots normally after FASTBOOT REBOOT
Does the bootloader need to be unlocked?
I really like to go back to Version B180 for my mate. As hassle free as possible.
Thx in advance

You will get error but after that flash boot into recovery and wipe.
Dload folder in sd-card is a must

Thx for the quick reply.
I did all that, but the only options i get are:
- normal recovery with reboot, factory reset and wipe cache
- or eRecovery when still connected to USB with the option to connect to wifi and download the latest package, which fails.
Other than that it's just a normal factory reset and the B320 Firmware boots just fine and welcomes me with the first start wizard.
My device is not really bricked. I just want to downgrade, maybe that doesn't work this way.
Also after the FASTBOOT FLASH ZIP UPDATE.APP there is:
...
writing zip..
FAILED (remote: Command not allowed)<--- this makes me wondering somethings not right, is it? This should at least work?
finished. total time: 12.077s
Hope you can help there

Daniel, to downgrade, first you need to unlock and then follow all the steps as written here.

FASTBOOT.EXE FLASH OEM UPDATE.APP
Do look here at times
Will try this after my Honor 8 gets charged.
It was bricked when updating from B162 (MM) to B320 (Nougat). Booting logo is the only one I could get, unless entering fastboot mode with holding vol- plus power keys when connected to a running computer. Three buttons (the above two plus vol+)results in bootloop as well.
Battery gets depleted unless charging when in fastboot & rescue mode. I'm going to charge it now (again).
BTW DC-Un... showed it was on B162.

Help. have anybody succeed downgrading from emui5 to 4.1?

i mean .. i tried everything
but.. still i stock on this ugly thing
can anybody help me?
im a NXT-DL00
kinda desperate
It's not as complicated as you might fear, stick with this and we'll get you back to 4.1
You have to be using EMUI 5's stock recovery for this to work, if you don't have it anymore use the Huawei update extractor to pull it and then install it via fastboot.
Then place the update.app file from the 4.1 firmware you want to roll back to into a folder called dload in your internal storage's root directory.
Turn your device off and hold VOL+, VOL- and power at the same time, it should enter dload mode and automatically start updating. when it is done you should be back to 4.1
You'll need to re-unlock your bootloader and reinstall TWRP for 4.1 but that should be it
any questions?

Ok, so you should already have it, unless you installed some form of TWRP since updating to EMUI 5.
If you don't have the stock recovery anymore:
extract the EMUI5 rom zip that you flashed to update to your desktop
download this tool on to your computer
http://forum.xda-developers.com/showthread.php?t=2433454
run it and hit the "..." button, this will open a new window, find the update.app file that you just extracted and select ok.
This will bring up a list of files one will be called recovery, right click it and click extract.
Then in fastboot mode:
Code:
fastboot flash recovery recovery.img
let it run and you should have the stock recovery back again

That is unfortunately not helping. If I do so the phone restarts and the Huawei Boot Logo shows up, but I am not able to enter erevory or somethin else. Only thing working is fastboot when I press Volume down.

Make sure you dont have the usb cable plugged when you try to enter recovery.
Have you tried flash the MM UPDATE.APP again ?

Yes I Trier without USB cable plugged in. What I recognised before the bootloop is: The flash of the rollback Version was successful but the phone was then already stuck in bootloop. So i don't even could install the real Version of MM.
Is there a possibility to install the stock Rom with fastboot? My bootloader is opened and I don't Kind if I lose all my data.

You should be able to put the MM update in dload folder of your sdcard, and use the 3 button method to flash it.
Otherwise use huawei firmware extractor to pull the system.img data.img boot.img from the update.app of the MM, and use fastboot flash system SYSTEM.img . Same thing for boot and data

Thanks for your answers and your help. The first method is not working, if I press all three buttons together, my phone just restarts and the Huawei Boot Sign shows up again.
I'd like to try the second method? But could you tell me, how I can find the system.img, data.img, boot.img files and where I can find the HUAWEI FIRMWARE EXTRACTOR.

Use this tool to extract them from the UPDATE.APP file of the MM: https://forum.xda-developers.com/showthread.php?t=2433454
First extract the RECOVERY.img only and flash it with fastboot. After that test the three button method again (make sure that you have the file from MM (2.0GB) in the dload folder). If it doesnt work, try the thing i said before.

OK, sorry for being such a noob. I now installed the Huawei Extractor. Furthermore I downlaoded stock Rom MM B130. Now there are two ZIP Files (like you can see on the picture). Do I have to extract both of them???
EDIT:
There is no data.img in Huawei Extractor. I have taken a screenshot of the files too (you can see it on the second image).

No, only the first (1.7gb).
EDIT: Forget the data.img for now. Try to flash the other files and even if it dont boot, use the version C432B160 to flash using dload method

Before I do the steps you discribed I have two questions.
First: I have to recovery images... RECOVERY.img and RECOVERY2.img. Do I have to flash both of them?
Second: I took a SD Card now and created a folder named dload. In it I put the UPDATE.app file. This has 3 GB, in your post you said it has to be 2 GB. So did I take the right UPDATE file or is it the wrong one?

I now managed to flash BOOT.img, RECOVERY.img and SYSTEM.img. Afterwards it was possible to extract UPDATE.app by pressing VOL up # VOL down # and the other Button (don't know the english word). But the installation of the UPDATE.app stops on 5%. Whats the reason for this?
So I have a guess right now: Before I tried to downgrade my phone I uninstalled SuperSu but I didn't unroot my phone. So my phone could be still rooted. Could this be the problem why the installation is not working?

If I try to do a factory reset in eRecovery it stops at 10 % and shows me a " ! ".
I could format chache, but afterwards my Bootloop problem is still not solved ...

Since I couldn't manage to rescue my beloved Smartphone, I now sell it on eBay. The Phone is in Germany, but I would send it to other cities in Europe for transportation costs of extra 10 EUROS. If you are interested and like to bid, here is the Link:

odin is for samsung phones, try unlocking the bootloader, fastboot flash twrp, flash oeminfo in twrp and then use the update.app and 3 button combo, there are guides on this forum explaining exactly how to do it. just make sure you have the correct files.

The symptoms are now.
1.Use a bootloader
2.Use twrp Can not access. Hang on the logos page.
3.I do not have a boot "Your device is booting now.."
And I tried flash with fastboot but It's cannot load system.img
