Guide to rollback huawei p10 from oreo to nougat - Huawei P10 Guides, News, & Discussion

Hi,(I am spanish sorry about my english)
after a long time searching how to rollback finally I have found the way thanking to this thread https://forum.xda-developers.com/p10/how-to/success-downgrade-oreo-to-nougat-t3729659.
In the thread the way to rollback isn't very extended explained so i decided to create mine and explain easy.
My phone is a Huawei P10 L29c432B.... .
Steps:
1- Download HWOTA8 from--https://drive.google.com/file/d/0B2D9GdWntw69U3N2aDEzZjY2S1E/view
2-Download Firmare L29C900B217 or L09C900B217 depending your model (only are 2 downloads) fromhttp://pro-teammt.ru/firmware-database/?firmware_model=VTR-L29c900&firmware_page=0
3-Delete the row "echo - - update_package...... update_data public. zip..." from the file "META-INF>com>google>android>update-binary" from hwota8_update.zip from the downloaded folder HWOTA8.
4. Create HWOTA8 folder and copy the following files: hwota8_update and MHA_RECOVERY8_NoCheck.img (from HWOTA8 folder), and the downloaded firmware files. After copu the firmware files you have to rename them one has to be named "update.zip" and the other one "update_all_hw.zip" (don't write.zip extension).
5- Now you have to rewrite the recovery with twrp, for that you have to go to fastbood (VOL- and Power) mode and connect to the pc. Then go to Uncompresed HWOTA8 folder and run "Replace_Recovery.bat" after that you will have the recovery TWRP installed.
6- Finally you have to to go to recovery pressing VOL+ and power button then go to Install adn search sd_external and inside HWOTA8 folder from sd card install "hwota8_update.zip". The device will resboot and start installing the nougat rom, but after that you will have to rebrand to L29c432.... to unlock all the functions.
That's all now you will have your device rollbacked from Oreo to Nougat.

Hi!
Thx for this guid, it seems to be clearly and good to understand! I have only one problem: i can not find the row "echo - - update_package...... update_data public. zip..." from the file "META-INF>com>google>android>update-binary" from hwota8_update.zip from the downloaded folder HWOTA8 for changing... ???
I tried with notepad++, but i can not do this... How did you get this step working?
Thx a lot!

You have to unzip the hwota8_update.zip file into another location, edit the extracted update_binary file and then repack the zip. The update_binary file in HWOTA8_<date>.zip is a binary file and shouldn't be edited with a text editor.

First few times i had the same problem...
When the phone is off an you will hold "Power" and "Volume+" button to boot into TWRP, just hold "Volume+" after phone is vibrating... Then you will boot into TWRP...

The fact is that the recovery proccess is a **** in this model. Try to power completely off the phone and the Pess POWER + VOL+ when you feel the phone vibrates retire the press of power button and still pressing VOL+ button by this way sometime it goes ok. If TWRP load go ahead with the followings steps.
Other way it to reinstall again TWRP untill it loads.
Let me know if you suceed, good luck.

4. Create HWOTA8 folder and copy the following files: hwota8_update and MHA_RECOVERY8_NoCheck.img (from HWOTA8 folder), and the downloaded firmware files. After copu the firmware files you have to rename them one has to be named "update.zip" and the other one "update_all_hw.zip" (don't write.zip extension).
2. Download Firmare L29C900B217 or L09C900B217 depending your model (only are 2 downloads) fromhttp://pro-teammt.ru/firmware-database/?firmware_model=VTR-L29c900&firmware_page=0
non-functional link?
How exactly is it to be?

just to let you know that nothing worked,
went to a shop, they tried everything, uploaded older firmwares, but after that the phone died, only black screen, couldn't even switch it on.
warranty did the trick
the guys replaced the mainboard, nothing else helped
so i'm waiting now for the official update

Good day! Can I use this method for installing Official Oreo from Beta? What I would like to do, is skip the deleting of row then just flash the twrp and continue with installation process.

I'm on VTR-L29C636B361.
I would like to rollback to Nougat, for root reasons. I'm trying to follow this method, but I'm not able to find the right files. All I succeded to find is the "update.zip", from Firmware Finder website, but no signs regarding others mentioned ("update_all_hw.zip"). Where can I dowload the right files?
Moreover: I flashed TWRP 3.2.1. I would like to go back on stock recovery, but again I'm facing a lot of problems. I would like to extract from update.app I have (from "update.zip" above mentioned), but HuaweiUpdateExtractor gives me a lot of error. Any help?
Thanks!

At the HWFF website the link leads you to you need to click the "filelist" (not only the "update"), that will give you links to all the files needed.
For the rest I am not sure, would also like to get back to the stock recovery but so far found no way to do so...

I can give you recovery.img and recovery2.img for VTR-L29C636B162. I flashed this and then roll back to Nougat (B172) with FF.

Hi, I have one question
Your phone was VTR-L29 C432 and you used the firmware of VTR-L29 C900, so can I use the C900 in any version to rollback and after that, what would be my version? C432 or C900?
I'm asking because for some reason I have VTR-L09 8.0.0.046(04VT) and I want to rollback, then rebrand and finally upgrade to VTR-L29 C432 with a custom kernel.
Thanks a lot!

This guide realy work ??

hello, I test by cons I have a problem, once flash hwota8_update.zip, it tries to restart in recovery and redémre on oreo, a solution?

Hello, I have a problem in the rocovery that I flash wota8_update.zip I have E: unknown command [errno]
Updater process ended with ERROR: 9
Error installing zip file '/external_sd/HWOTA8/update.zip

Maybe this is a silly question. Do we need to change the recovery file since MHA is a code name for MATE 9. P10 use VTR. Is it still usable?

No storage after installing ROM

Goodafternoon,
I tried to root my Honor 7, but failed, don't know why, was stuck in a bootloop. Then I unfortunately deleted the whole system with TWRP recovery..
Then I downloaded the current ROM from a forum called modaco which seemed to be trustworthy and extracted it with HuaweiUpdateExtractor to then install the data with fastboot. I installed everything like system, boot, data etc. and everything works fine, except for the internal storage. Normally it should have about 13 GBs, but now has less than 3. When I go to Storage in the settings, it tells me I only have 3 GB internal storage in total.
As I don't exactly know how to describe this problem and therefore don't know how to google it, I ask you. If you need some more information let me know.
Would be very kind if anybody could help me or have some advices as I am not a real genius in doing such things.
Thanks!!
Hi,
First of all, is the custom rom deodexed ?
because on stock rom ( emui ) , you juste have to go into recovery, then factory reset, with a Custom, idk
I can only tell you before trying factory reset, make a full backup, then you could try

After manually flashing all the .img files you should perform a force update aka three button update, by putting the same version of UPDATE.APP from which you extracted those .img files.

So you mean, I have to flash the phone with bootloader with the extracted files from update.app and then put it on my SD card and manually update my phone with exactly that update.app file? or am I wrong? I already tried something similar, but couldn't find the option in my honor 7 in the update settings, to manually update (I have put the update.app on my sd card).
I tried to install another ROM (MoDaCo - ROM) with hard resets etc. but didn't solve the problem.
I do exactly have 3.87 GBs of internal storage after flashing the new ROMs or update.app files. I found somebody else with the exact same problem. He solved it by hard resetting his phone with the TWRP recovery, but didn't work for me. In that forum they told him, he has some "ghost ROMs" on his phone, from flashing his phone before.
If you do have any ideas or clues for me, don't hesitate to tell me. And thanks for your help!!

Yes, you have to do exactly that, flash files like cust.img, system.img, recovery.img, userdata.img(DELETES YOUR DATA), boot.img after extracting them using Huawei Extractor tool from UPDATE.APP.
After you do that follow below steps:
Put that UPDATE.APP in dload folder in your External SDCARD.
Switch off your phone.
Press the three button combo (Vol UP + Vol DOWN + Power).
After this your whole device will get flashed with that UPDATE.APP file you put in dload folder.
Try these steps, then tell me if the problem still persisits. I hope this solves it.

Sorry last question:
Currently I have the custom MoDaCo ROM installed (don't know if you know it). To follow the steps you mentioned above, do I have to get back to stock ROM first, or can I just leave ROM as it is and flash it?
Thanks.

No you can leave it as it is, it will get wiped in the process.

Thank you so much, everything went fine! Great!
To update my firmware in future, I have to download the new update.app and do the 3 button update, right? Or any other way? Are OTA updates no more possible?
Thanks again :laugh:
@Maxdr13 If you are rooted, then flash manually the img files then do a three button update, but if you are on stock ROM and recovery, just dong three button update by putting UPDATE.APP in dload folder will do.

and userdata etc. won't be wiped with the three button update (phone is not rooted) ? is there no chance to get back to normal status so I can update with OTA?
@Maxdr13 I can't confirm about userdata, as once I did a three button update my data was intact, but some people also reported that data gets wiped, and after the three button update you will get OTAs.

[SOLVED] Bricked + Formated my Honor 7. Need a ROM

Hey guys,
I've had a total of 4 android smartphones during the last years, and I did root all of them and even install diferent ROM's, but on this phone (Honor 7) was kinda diferent.
The root process is way more complex than all the other androids I did root (simply flash a .zip file...) so I've been post-poning this task over and over..
Finally yesterday I gained courage to try out rooting my phone, and while attempting to root my Honor 7, after flashing SuperSU from TWRP, my phone no longer booted.
Stressed as I was, I just told to myself "f*ck it" and formatted the system and I didn't care much if there was a fix without needing to format the system. (but then I realised that I could not find any .img ROM files to flash from TWRP recovery, so basically I did my actions wrong once again)
I followed the tutorial from guidebeats.com which talks about rooting EMUI 4.0 Android 6.0 (I cant post links)
Basically this is the story:
While unlocking the bootloader, even though, the tutorial said the phone would reboot itself after typing "flashboot oem unlock 1234934829" I did a hard reboot (or reset?) holding (VOL+) + Power button and I have the feeling that the bootloader unlock was not 100% done, even if it said it was unlocked. (Phone was working perfectly fine there)
Then I flashed SuperSU, and I could no longer boot. After powering up my phone, after the first splashscreen, the screen would only turn black.
What (I think) I need to now is remove the TWRP recovery, and use the stock one and attempt to install an "update" using (Vol+) + (Vol-) + Power. (please correct me if I'm wrong)
But now there's some issues I got that I'd like some help with:
1- How can I get back to the stock recovery? (NOTE: I currently got no OS installed on my Honor 7, since I formated it)
2- Will I need to lock and unlock my bootloader again (if I want to 'fix' the bootloader unlock?)
3- Where can I get official Honor 7 stock ROM? (would be awesome if there was already the Android 6 stock rom for a clean install)
4- What are the steps on this tool (Honor 7 Multi-Tool) to root my phone?
I need my Honor 7 asap
Sorry for the long post, It's my first time doing a more advanced root and I have all these questions.
Thank you very much for any kind help!

As you are already familiar with adb and other stuff so will write a short post for you.
To download latest firmware, head to
http://forum.xda-developers.com/hon...tock-firmware-packages-honor-7-t3448747/page1
Google, download and install Huawei update extractor and open UPDATE.APP in it (obtained after extracting firmware).
You can see all the images. Just extract recovery and boot to platform-tools folder.
Meantime, do the unlocking command again, with
Fastboot OEM unlock xxxxxxxxxxxxxxxx
Followed by fastboot reboot
And press and hold the vol down button again until you reboot in bootloader.
Flash the recovery and boot you extracted using
Fastboot flash recovery recovery.img
Fastboot flash boot boot.img
(I got a habit of extracting and flashing system and Cust using
Fastboot flash system system.img
Fastboot flash Cust Cust.img
But they are not necessary)
Now you are set to try a 3 button update (sometimes it gets stuck so if it's stuck for 15 minutes, try 3 button again).
Please do report back if it comes to life.
To root, just flash twrp and then use SuperSU 2.62 (no other version) and update it later using play store.

Hey!
Thank you alot for your reply.
From the link you sent about the firmwares, there are alot of Builds for the L01 (EU) model. Can I simply use the latest from the list or I gotta install 1 by 1 (from older to newer)?
Also, the bootloader unlock thing, is it ok if I wait to do it until I install the stock ROM again? Because I think I don't have the code anymore (Also don't know about IMEI)
Other thing, yesterday before bricking my phone, I tried to re-unlock the bootloader as you said above, but it didnt let me because "it was already unlocked".
I really have no idea if it's 100% unlocked or not.
important thing!
With those ROM's, I still have the right to receive official OTA updates from the HiCare app right?
Thank you again

Just use B380 as it's the latest full firmware available there.
Unlocking bootloader again was just a precautionary measure (proceed without it and if it is not 100% unlocked and if something goes wrong, we can troubleshoot later, which imo, won't happen)
And yep, if you keep the firmware as it is, but if you flash twrp and root, you will still see the update available in Hicare but will have to install stock recovery again before upgrading. (Nothing else is needed as SuperSU 2.62 gives a systemless root so you only need to flash back stock recovery for an update)
I am not against honor-tool bit it's best to do things manually as it makes you learn stuff and is easy to troubleshoot if something is amiss.

Alright, btw, about the thing you said
"Now you are set to try a 3 button update (sometimes it gets stuck so if it's stuck for 15 minutes, try 3 button again)."
I gotta do that myself with an "update.app" file or what?
Sorry, I missed that part
Cheers!

You have to make a dload folder in SD card and copy UPDATE.APP to that folder.
Then just turn off the phone, press and hold power + vol up + vol down until phone boots.
Let go of power but keep others two pressed for 5, 6 sec more. Your phone will boot into recovery and start installing UPDATE.APP
It likes to get stuck at 5% (most reports) but sometimes, somewhere else. If its stuck for 15 minutes on a particular percentage, just press and hold the above three buttons again using the same process.
Multiple tries make it work...

The problem was on the SuperSU that I flashed, it was version 2.71, instead of the one you said » version 2.62 «

That's great... Enjoy your phone and as for coffee, well, let's say, you owe me one and we will leave it at that
Better yet, you can search DigiGoon and pay him for the coffee, he taught me what I told you.
You can find him somewhere in this thread

Hello
How did you format your phone?
I'm still struggling with going back to Android 5 and EMUI 3.1 since there is no rollback file available. (PLK-AL10, B396) Maybe formatting and installing the old rom could be a solution, like in your case?

Hello.
Do you have unlocked bootloader and TWRP recovery? You can format your phone from TWRP recovery.
I think the only option for you is to get the old ROM img and flash it (starting from 0)
You can dirty-flash (Flash a different ROM with same android version as yours, e.g: flashing custom android 5 ROM over your stock android 5 ROM without factory resetting your phone) but I dont think you can do that from Android 6 to 5.

Yes I have unlocked bootloader and currently not twrp but I can flash it at any time.
The last two paragraphs you wrote are different solutions or the last one is a more detailed explanation of the previous?
I have android 6 so the later method won't work as you said.
But formatting it and flashing a stock android 5 rom - is it that simple? Nobody here suggested this before, however I have been asking for months.
All the phones are empty when they leave the assembly line.
How did you flash the new rom to your formatted phone? Extracted update.app and flashed each file with fastboot? Any issues you faced?

From my last 2 paragraphs, the first was a solution, the second was an impossible alternative that I thought it would work.
My issue was that I had a custom recovery but I had no ROM installed, so I had to install the stock recovery and boot (extracting from update.app) and flashing it via fastboot, to afterwards force the update with 3-button method.
-----
What you'll need to do is:
- Flash TWRP
- Wype system, data, cache.. (so that you completely delete your current ROM)
- Extract recovery.img and boot.img from an update.app of an Android 5 ROM you'd like to have (Official ROM for your device model)
- Flash them via fastboot (You'll go back to stock recovery again)
- Shutdown your device
- Create a folder named "dload" on your sdcard and put UPDATE.APP file in it.
- Reboot
- Do the 3-Button update ([Vol+] + [Vol-] + Power)
- If it works, it will auto install
(- If it gets stuck on 5% for over 5/10min, force reboot pressing [Vol+] + Power) and try again the installation
- After installing it will boot normally (first boot takes a while)
NOTE: I'd recommend creading the dload folder before wiping the ROM, because usb didnt work for me afterwards. (It would still work if I was on recovery tho)
>> Remember to make a full system backup before wiping aswell, dont be stupid like me xD (thats why I had to full wipe my system after soft-brick)
Im answering based on what I did and was explained here to me

Hi again,
I'm doing this OS installation now. It starts fine but stucks at 90%, (I'm trying to install the latest stock ROM which can be downloaded from Huawei site, B220 or221). Did you have the same issue? I waited more than half an hour at 90% but did not go on.

Maybe formatting, Flash stock Android 5 recovery using Honor multitool , and then Flash a Android 5 firmware
Not sure it Will Work without rollback..
Finally, after 2 months of struggling I managed to get back to Android 5 and EMUI 3.1 without a rollback file.
Here is what I did:
0. Download a full ROM you want to install
1. Backup of the current system with Hisuite (everything. Apps, media, contacts, call log, etc.)
2. Flash TWRP recovery with fastboot (start phone in fastboot mode)
3. Wipe (and format!) everything you can with TWRP
4. Extract boot.img and recovery.img from update.app of the new ROM with Huawei Update Extractor
5. Flash boot.img and recovery.img with fastboot.
6. Copy update app to dload folder on SD card, insert into the phone.
7. Restart phone with [VOL+] + [VOL-] + [Power] buttons to force update.
8. The system will be installed from SD card. I had no issues with the installation. First I did not format the phone (just wiped) and it did not work.
9. Restore data from backup.
The only strange thing is that the native app icons look different than my previous lollipop system. Don't know why. They are less colorful. I installed C00B220 for PLK-AL10.

Yes it does. (It did for me.) Technically this is not a rollback but installing a brand new system on an empty phone. That's why it is important to do a backup upfront.

Thanks for the answer. Im gonna try this method. I can't reflash any region rom.

KIW-TL00 B430 Stock firmware failed to fastboot downgrade, bootloops

I just make my mobile unlock(KIW-TL00C01), I have tried
1. extract the image of UPDATE.app from B228 and fastboot flash (failure)
https://forum.xda-developers.com/honor-7/general/guide-beginners-how-to-root-update-fix-t3255452
2. using e-recovery(internal recovery), put firmware zip file(B228) in dload directory in SDcard, inform failed at 5%,
if you put that file in root directory of SDcard, it would stop at 5%.
3. install the 3rd part firmware from TWRP recovery(installed, but reboot would make the touch screen support in all the place, and boot loops)
I have tried install a different firmware through the adb when the touch screen is broken.
I use the following command, I didn't find a one could work.
Code:
recovery --update_package=/external_sd/firmware.zip
The one thing I could do to is put the UPDATE.app of B430 into dload, and retry the method 2 or my mobile is complete brick.
I wonder does the Huawei update the signature or firmware of TrustZone?
I don't know anything I could do to make it work.
if you want to downgrade, you first have to dload the rollback package, then the actual firmware
the rollback package

where are you getting your files ? what is the Full version of your phone KIW-TL00C00 or KIW-TL00C01 or KIW-TL00HC00 ?
you must use the exact version for your phone.
the only useful info on the Honor 7 link you posted is how to flash from dload
nowhere did you say you put update.app in dload folder on ext_sdcard and flash with power + volume up and volume down
First determine the correct file for your phone and then flash it correctly

After you entered fastboot, flash twrp, then restart to recovery and copy stock firmware to sdcard.
Even if it fails, you can hold VOL+ button during startup to enter eRecovery, where you can revert to stock using nothing but wireless LAN
P/S : I'm also stuck at bootloops trying to install lineage and mokee, please post a guide if you have done it successfully

[GUIDE] How to unbrick P10 "easily"

Hello all,
First of all the story.
I used the script to rebrand, it has a fail but the phone still working.
One evening, i decided to wipe all by twrp and re run the unbrand script..... that was a huge error, the phone boot but boot loop, and after, the script stuck an no recognise the twrp on the phone.
Tried lot of things like flashing recovery etc in fastboot but nothing else happen than a boot and a black screen with nav bar only.
At this point i think the problem is that i was unable to flash cust.img with fastboot
Whad did I Do?
(Bootloarder must be unlock)
1st: Crying.
2nd: read tons of things on XDA
3rd: Try to re run the script but fail because the phone was still rooted.
4th: Crying
5th: Read lot of other things on XDA
6th: this is the good IDEA
7th: Download Huawei firmware finder
8th: Download Huawei Multitool
9th: Download Huawei Update Extractor
10th: download by the tool the full OTA firmware and dependencies (in my case VTR-L09C432)
11th: extract the update.app (chose "other" for phone model) from the big "update.zip" dowloaded before an put it in a folder of your choice
12th: extract the update.app from the "update_all_hw_xxx" dowloaded before an put it in other folders, just incase of files could have the same names (not sure of it)
13th: run Huawei Multitool (il will create a folder in the path of where the app is when you click, the folder you need is "unbrick")
14th: choose 6 on Huawei multi tool, it will show you what img's you need, and you need everthing exept data.img (the cus.img is in folder wehre you extract update_all_hw_xxx) in "unbrick" folder -> Place the .img needed in the "unbrick" folder (very important)
15th: boot your phone in bootloader mode (phone off, vol-down+plug USB)
16th: clic the button to launch procedure (press N)
17th: have a coffee during the upload it'll ask to reboot
18th: If the problem is solved: cool, stop here
IF NOT: shutdown the phone
19th: Go in classic recovery: Phone off, Vol-Up + Plug USB, when huawei logo stop pressing vol-up
DO NOT BOOT eRecovery, it will not help
20th: in classic recovery do factory reset AND cache reset
21th Reboot
You can relock your bootloader if you want with your code.
The only thing i don't know to do and if someone can telle me is, before the flash of every things or at a moment, if i can flash via ADB the OEM info for an official bootloader relock.
Thx to @mankindtw, @worstenbrood and @inside!out
Hope it will help, it work for me.

When you download the 3 files of the firmware, place them where you want.
When you lauchn Huawei Multitool, it will create the "unbrick" folder in the Huawei Multitool folder (my bad) not "brick", i update the first post.
When you use Huawei Update Extractor, you have choices for type of firmware, chose other.

omg, how do you do that? you mean a advanced mode is in recovery mode or erecovery mode? I brought p10 at bell, I just couldnt find its firmware number.
ive done everything in this thread. the multitool installer finished without errors, then i did vol up + vol down + power, and it froze at 5 percent "installing update" then entered a reboot loop. then i tried a factory reset with vol up + power and it stoped at 25 percent.

opt 6 is in my memory "unbrick" or recover.
You have to put all the .img files needed exept data.img that is not possible to heve because this file is on your phone and encrypted.

I'm sorry, I'm a bit confused on the intructions:-
I downloaded the full update zip file from the url using the firmware finder, there was another url link that came up called full/public/update - do I need the zip for this too?
I extracted the update zip to a folder and then extracted the update.app file using the Huawei update extractor.
Now I have a very long list of .img files in the extractor and I'm not clear what I need to do next i.e do I move them all into the unbrick folder on the tool?
Hi, I have since been able to extract the right files for the multi-tool. I extracted them again from the extractor. I now have placed them into the unbrick file. My problem now is that I can't run the tool - when I open the multi-tool .bat file its asking for a proxy port, where can I find this?

There are three variants:
(for Oreo only, and keep in mind, that OEMINFO changing will lock you bootloader again).
A/ use HwOTA Tool
HwOTA8-ANE
B/ install TWRP for Oreo
link:
TWRP-oreo-smart
Download OEMINFO C432 :
OEMINFO ANE-LX1C432
Unpack .zip file and transfer oeminfo .img file to the SD card
Using Firmware Finder for Huawei apk, search for Oreo ANE-LX1C432 . Select FullOTA-MF, download the three files. (For example: find ANE-LX1C432B178 No.230902, download update.zip, ANE-L21_hw_eu.zip and publick.zip.)
Rename update_data_*.zip to update_data_public.zip
Rename update_full_*.zip to update_all_hw.zip
Don't rename update.zip.
Download HuRUpdater.zip
http://www.mediafire.com/file/r14sor2g4cbugzw/HuRUpdater_0.4.zip
Prepare an folder on SD card, like so:
myupdate/
HuRUpdater.zip
update.zip
update_data_public.zip
update_all_hw.zip
Boot into TWRP, flash OEMINFO C432.img (- in TWRP select Flash image). Go back to the main TWRP's menu, select Install , select 'myupdate' file and tap the HuRUpdater.zip , confirm.
You may need to press Volume Down for HuRUpdater to continue!
Reboot system.
C/ Download Oreo Service ROM , e.g.
Service ROM 8.0.0.178
Unpack .zip archive, find dload file in Software folder and transfer it to the SD card without unpacking it.
Install TWRP over eRecovery (you will need Stock Recovery due to the dload method).
Flash OEMINFO C432 , go back to the main TWRP's panel and select Reboot > Power Off.
Use three button combo to flash Service ROM . The process will erase all your data and will lock the BL again!
Note: how to install TWRP over eRecovery:
- copy to SD card TWRP-oreo-smart.img
- Download and copy to SD card Oreo Stock recovery~ramdisk :
Recovery_ramdisk
- in main TWRP menu tap Install image, then navigate
to the TWRP-oreo-smart.img, select
eRecovery Ramdisk and confirm . Go back, navigate to
Recovery_ramdisk-ANE-OREO.img , select Recovery Ramdisk and confirm.
How to boot into TWRP: reboot your phone, when unlocked bootloader warning appears, press Volume Up key up to 3 seconds to enter TWRP.

Just to let you know, even that I need a combination of method a and b. I finally rebranded my C461 version to the wanted C432. I've tried method A but ended with something like ( system.8.0.0(OSAV) ) with no update option.
I then used the files from this link to use them for method B to correct this issue:
http://update.dbankcdn.com/TDS/data/files/p3/s15/G2496/g1789/v225235/f1/full/update.zip
http://update.dbankcdn.com/TDS/data/files/p3/s15/G2496/g1789/v225235/f1/full/public/update_data_full_public.zip
http://update.dbankcdn.com/TDS/data/files/p3/s15/G2496/g1789/v225235/f1/full/ANE-L21_hw_eu/update_full_ANE-L21_hw_eu.zip
The phone now offers to upgrade and I also get the C432 in the build number. So one step further to custom roms or just stay on stock and get root to remove some bloatware...
Thank you Alf for your help!
Fall in love with Huawei again?
