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

Bootloop after trying to downgrade to MM

Hello,
today I tried to downgrade from nougat to MM. After the MM Rom was installed, my phone only shows me the Huawei Brand. The phone does not start, it only shows huawei brand. How can I rescue my phone now ???? Please help
Edit:
If I press Power + VolDown it says PHONE Locked, FRP Unlock
I tried the rollback with this method:

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?

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.

please I need to remove twrp recovery

I need to remove twrp recovery and install stock recovery image
How I can do this gra ul10

Hello! You would be willing to change the ROM?

Uh oh. This reminds me 1 year ago when I had your same problem . The process is simple:
1. Get the UPDATE.APP file wich is no more than all the stuff for the P8 wich includes the recovery. You should find it on emui.huawei.com
2. To see what's in there you need a tool called "Huawei Update Extractor". Just look for it
3. You do the same process for installing TWRP but with the image file "recovery.img"
And you're done
PS. Do a full backup with TWRP just to be sure. To restore it just reflash TWRP and use the restore function

You could flash the original recovery via fastboot if you have a backup of it as raw image.
Or well what @Rome7643 mentioned works also. I submitted a profile for the gra-l09 for the update extractor.
command is like "fastboot flash recovery <path/to/recovery.img>"
There is recovery and recovery2. One of them comes up when usb is connected one when it is not connected when triggering the recovery boot.

Download the UPDATE.APP from a recent stock rom, use the Huawei Update Extractor, then flash the recovery/recovery2 partition with the recovery.img/recovery2.img.
Like "fastboot flash recovery recovery.img" in fastboot mode.
This will only override recovery.
Note that recovery and recovery2 is the same but one triggers only when the usb cable is connected.

Please, next time you should be more careful when downloading the file UPDATE.APP or update.zip ! I guess you downloaded one from Huawei P9, but for sure it's not for Huawei P8 !
After you unpack update.app there should be RECOVERY.img and RECOVERY2.img along with others partitions images.
Good luck !

I am sorry if I posted in the thread for the wrong phone. I have a mate 9.

Bricked? Broken? Dead? I have lost all hope... - I can't enter fastboor OR recovery..

fixed. idk what i did fastboot randomly worked again :/
------------------------------------------------------------------------------------------------------------------------------------------------------
Hello there. So I have my Huawei P10 plus for about a half year now, and I found out the huawei's unlock bootloader code site worked, so I just jumped straight at it and unlocked my bootloader.
Everything went well, i could go into fastboot, installed twrp, everything worked fine. Rooted the phone bblablabla..... Then I realised I could not use Snapchat anymore because of the root.
So, I had SuperSu installed. I tried to unroot via there, didn't work. So I clicked "use another root app", wich basicly bricked my phone - i think - . After doing that, supersu wasn't gone yet. So I flashed it away with a zip in TWRP. That broke everything.
Snapchat worked, so I didn't bother that much. But the thing is,
i couldn't change theme of my phone
i couldn't update system anymore.
I tried over 10 days trying to get this fixed but nothing seems to help.
forcing into fastboot, twrp, or huawei's eRecovery, it all just bootst into the default boot or phone.
I have lost all hope and I don't honestly know what to do.
So I can still use my phone, but I can't do system updates or change the theme, and probably more things I didn't yet have found out. I'm sorry if my English is pritty broke, I'm just so pissed off atm I just don't know what to do anymore except for making a post like I'm doing now.
Please, help me.
Thank you.
PS: I know what some people are going to say: reinstall or flash the default rom and hard factory reset. Okay good, first of all I can NOWHERE ON THE ENTIRE INTERNET find my default ROM (boot.img etc), and I can't flash ANYTHING cuz i cant go into fastboot or TWRP.
i am ded
plz help

Hey!
So yeah, just flash your default rom.
It will wipe everything.
For this you have to use firmware finder, or go to this site (for VTR-L09. Type VTR-L29 in the search bar if you have this variant).
Click on filelist when you see : 2018.02.11 VTR-L09C432B185 (/!\ latest Nougat update).
Copy and past the first link that the filelist will provide.
Then download Huawei Update Extractor and Huawei Multi-Tool.
Open the update.zip file and extract the UPDATE.APP somewhere.
Open Huawei Firmware Extractor, click on " ... "and select your UPDATE.APP file.
Right click somewhere in the list and select "Extract all".
Extract everything to a new folder.
Power-off your phone, press vol-, plug your phone to your PC and press power (while vol- is pushed down). You should be in fastboot mode.
Open Multi-tool, go to the Unbrick tab, click on Specify a folder, select the folder that you have extracted the UPDATE.APP to, and hit OK.
If all the boxes are checked (System.img, boot.img, cust.img, recovery.img and userdata.img), you should be able to click the "Brick" button.
If you don't have cust, then you'll have to download the files on the 2nd and 3rd link that I gave you earlier, one of them contains an UPDATE.APP file, you have to extract it and extract its content with Update Extractor to the same folder that you have extracted the content of the previous UPDATE.APP file.
It will take time to flash, but when it's done, it's written in the Progress window in multitool.
When you're done, just update to oreo and follow the TWRP tutorial for oreo and the one for magisk, SuperSU is really outdated.

Well I just did a quick read at your text and saw you needed fastboot. I think you didn't read my post. I can not enter fastboot, otherwise I could have probably fixed it myself. Any suggestions?

I read your post.
Usually to enter fastboot you press vol- and power, but with TWRP you can't do this anymore (my case).
That's why I said : vol-, plug the phone to your pc and instantly press power while pushing vol-, that's the only way that I can enter fastboot, give it a try :good:

I want to patch new updates of emui 9 with latest google security patches so which no check recovery i use on emui 9.

OK it works very well and EMUI9 is ​​definitely better than version 8; on the other hand how to reinstall TWRP?

I found this post from anteO

You don't need TWRP to install Magisk; for that matter, they can't be installed simultaneously on EMUI 9 together anyway.
The EMUI 9 method for Magisk is to patch recovery_ramdisk.img extracted from update.app, flash the patched image, and boot to recovery from then on. (Huawei made it impossible to load a custom ramdisk on Pie otherwise.)

Thank you irony_delerium for info's, but is there not a tutorial explaining the steps of modification ?

1) Make sure you've got the stock firmware zip files. (I'm assuming you do.)
2) Extract UPDATE.APP from the main update.zip file (the big one).
3) Using Huawei Firmware Extractor on your desktop (search on XDA for it), load UPDATE.APP and extract the recovery ramdisk image. It's going to be "RECOVERY_RAMDIS" in that app as I recall.
4) Put the image into your phone's internal storage (MTP works, though I've never used it, I usually use adb: adb push RECOVERY_RAMDIS.img /sdcard)
5) Install Magisk Manager on your phone. You want the current release (18.1) at the very minimum. Canary builds also work
6) Select the Install button in the Magisk interface. Select "Patch boot image". In the file browser that comes up, select the image you just transferred in #4.
7) When Magisk finishes, pull the image back to your PC (adb: adb pull /sdcard/Download/patched_boot.img)
8) Reboot to the bootloader and flash (fastboot flash recovery_ramdisk patched_boot.img)
9) Reboot to recovery (fastboot reboot, pull the USB cable and hold volume up).

Thank you irony_delerium ; very clear tutorial ; on the other hand, in UPDATE.APP there are 2 RECOVERY files : RECOVERY_RAMDIS.img and ERECOVERY_RAMDI.img which do the same weight; patching MAGISK with RECOVERY_RAMDIS.img I arrived at a system error and a dialogue asking me to either erase the data, or a factory restore; on the other hand with ERECOVERY_RAMDI.img it was installed alone? does it seem normal to you?

1) Make sure you've got the stock firmware zip files. (I'm assuming you do.)
2) Extract UPDATE.APP from the main update.zip file (the big one).
3) Using Huawei Firmware Extractor on your desktop (search on XDA for it), load UPDATE.APP and extract the recovery ramdisk image. It's going to be "RECOVERY_RAMDIS" in that app as I recall.
4) Put the image into your phone's internal storage (MTP works, though I've never used it, I usually use adb: adb push RECOVERY_RAMDIS.img /sdcard)
5) Install Magisk Manager on your phone. You want the current release (18.1) at the very minimum. Canary builds also work
6) Select the Install button in the Magisk interface. Select "Patch boot image". In the file browser that comes up, select the image you just transferred in #4.
7) When Magisk finishes, pull the image back to your PC (adb: adb pull /sdcard/Download/patched_boot.img)
8) Reboot to the bootloader and flash (fastboot flash recovery_ramdisk patched_boot.img)
9) Reboot to recovery (fastboot reboot, pull the USB cable and hold volume up).

Hello
If you wouldn't mind confirming a few things from your post, as I'm trying to do this.
Is the sole purpose of extracting the big file to extract the recovery_ramdis ? You don't mention if anything is done with the big file.
The ADB commands didn't work for me, (error: push requires an argument).
But, I sent the recovery_ramdis via magisk manager, and it worked, then advised me that it put the image in /storage/emulated/0/Download/patched_boot.img but I can't find that location.
OK, edit ... I found the file and flashed it, rebooted into recovery and I get the message software installation failed.
I've had a whole lot of failures, phone won't root despite magisk giving no errors, dload won't work, superSU won't work.
Update .... root decided to work out the blue so I tried EMUI flasher and it looked like it was going to work ... but failed the update at about 10%.
Update - Bricked.
