From stock recovery wipe data factory reset and wipe cache(this will delete all data from phone,so make a backup before),putt phone in fastboot/rescue mod an flash again b132,reboot phone,now use this vendor (extract and rename folder to dload,copy to memory phone and make local update),when is done,use this ota update (extract,and putt update.zip in folder dload and make local update),now your phone should have build number Ale-L21C432B170,and for android 6.0 just make a local update with this

Many thanks for your guide! I will apply your advices and will report the result.
Also, I would like to ask something that makes me worry a little, why the Nandroid restore has not restored everything exactly as before?

At this point, what B132 I have to flash? I have this: ALE-L21 C432B132 Europe channel Dual but inside is the update.app (in dload folder). I presume that you mean a zip file, maybe a OTA?

You must extract from update.app using huawei update extractor and extract files:boot,recovery,cust and systems then flash by using fastboot commands

Help! VNS L31C900B300 Locked bootloader.

Hi guys, i updated my VNS-L31 into nougat test-key, i wanted to downgrade to stock MM because there's a lot of bugs, when i'm trying to install img file from fastboot, it always failed and i saw in my phone "Phone LOCKED" it was previously unlocked. Can anyone help my unlocking my device with

Use the same unlock code you've used before, get it again.
And why are you using that build B300, you could have at leasT tried B336, which in my opinion isn't having any problems noticeable, battery drain also good...people complain about this, but if you know what you're doing this will never be an issue.

Thanks for the response, I'll try tomorrow, i've already forgotten and deleted the code. Actually, it's all misunderstanding on why i flashed this build lol. I am planning to revert to MM stock and i'm still looking for some guide on how to. I tried other methods and didn't get luck. If you have any ideas would you mind helping me again? Thanks!

Yeah I've already seen this and i'm not sure on what to download, i tried once but it says
"software install failed!"
"Incompatibility with the current version.
Please download the correct update package."
and i can't still unlock my bootloader, the website is new, and it won't redirect me to unlocking SITE from this thread LINK.

This method don't require unlocked bootloader, don't require TWRP.
Just get the rollback file and full MM update file.
Install rollback first then MM file after, put the extracted update.app files In the dload folder on root of sdcard, one by one after each install
Or
If you don't want to use rollback file, unlock bootloader, then flash patched oeminfo file via:
1.fastboot using this command: fastboot flash oeminfo xxx (xxx= name of oemifo zip you have, ie. fastboot flash oeminfo C432oeminfoDual.zip)
Or
2.while In fastboot flash revolution nougat recovery, then boot into it by "vol up + power" then flash the patched oeminfo,
Then once flashed OEMINFO then install via 3 buttons mode the update.app of your firmware, this must be in dload folder on sdcard as above.if asked for password then use "reset"

Edit title to solved.
The current TWRP by Revolution for nougat can't mount /data partition, and if you need flash anything there, you've got to change filesystem as advised In the tutorials, but you can flash mods or apps to system partition without problems....this problem is In nougat TWRP only currently, MM TWRP has no issues at all...anyways good to hear your sorted!

if you follow the instructions closely and have the correct oeminfo and firmware all should be fine

So, here, what I could find and install nougat.
Firmware full-ota-mf not pv.
For, full ota mf, there are three files.
_ Update.zip.
_file public.zip.
_file datafull.zip.
Uses huawei extractor to unpack update.app of update.zip and file datafull.zip.
You can find and install.
With adb and flash fastboot
_boot.img
_system.img
With twrp edit hassan install image.
_vendor.img
_ Cust.img
_ Version.img.
On nougat the device works correctly.
Now I am looking for a solution to install product.img
Any help or advice, would be welcome.
thank you

I have the files for BND-L24 uploaded and want to share same method of restore , for US version. As the method is the same.
Would it be ok to link to your thread from a new thread with L24 files attached , or add the backup here and just change the title?

All the post I see about manually flashing Oreo say you CAN NOT return to emui 5. So I would believe no
**EDIT**
I see now on firmware finder there are roll-back to emui 5.1 full-ota packages.
right now only for
BND-AL00
BND-AL10
BND-TL10
but perhaps after flashing that full ota to get partition table back , then follow this method from here to get correct regional specific parts back.
All still untested at this point

Suppose if I install Other rom first like AOSP or RR?

I have no first hand information. Just that for RR you need to first update to Oreo, so same as before, the information at this point is, NO , roll-back is not able.

Your other post show you are on Oreo. This method, files linked are Android nougat.
You need to replace twrp with stock recovery, then wipe cache from there. This should fix your bootloop ,caused by wipeimg cache in twrp. Unless there is more to the story than you tell.

Well it twrp is not staying on, then fastboot will have to be the method to recover
Hope this will work
fastboot format cache

If those not work, or not allowed try

the downgrade is tricky , if not done with full downgrade files. It is pretty much a half full update, then restore a backup. There are many things that could cause trouble with this.
Did you try to factory reset after failed OTA?

Rebranding to FRD-L09c10 OREO (russian)

I have found this tutorial in the comments of a tread, and it worked for me, so I decided to bring this tutorial in a new tread so everybody can easily see it:
Thanks hackslash for this tutorial.
To rebrand, you need an unlock bootloader.
1. Download the C10 oeminfo file https://mega.nz/#!aBhnDKAK!qeVVAjcApTl7fqjwHcPMUS6ITUDHL9Rx0u-4k8rx0c4. It is a zip file, extract it to find an img file. Reboot to TWRP and select Install Image and install the file to oeminfo partition.
2. Perform a complete factory reset in TWRP.
3. Download the latest Nougat (3 files package) for FRD-L09C10 through Firmware Finder. Flash it using HuRupdater https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279.
4. After the flash is complete, reboot the device, unlock the bootloader again and flash TWRP.
5. Download the latest Oreo build for FRD-L09C10 through Firmware Finder. Using HuRupdater flash the three Oreo firmware files. Don't perform a factory reset this time.
6. Reboot your device. You're now on Oreo.
(brightness dimming still happening in some apps on oreo)
(I also have tested Pixel experience treble (GSI), and guess what? I got in bootloop, yeah... thanks huawei for the amazing software work ...)

Will I Be Able To Install Unapproved Updates With HurUpdater?

@SuperSwordSmasher Yes you can install every stock firmwares.

@immichao - can you correct the links as they do not work

Deleted

Just updated the links

About GSIs, there are special GSI for Kirin devices. And don't worry they'll be released by the OpenKirin team with support for Honor 8 shortly.

I flashed Oreo onto my FRD-L04C567 using these instructions and now my device will not connect to LTE. It stays on 3g HSPA. Do you know how to reactivate the LTE radios?
