Unlock bootloader, flash twrp and install update.zip and full_update.zip for your device
Or you could try to find the files to update the devices via dload to a other firmware, but I'm not sure that works, because you want to change the cust.

I don't know, but you can try to install the newest version before nougat and than flash the first nougat version for your device.

First you must flash stock recovery. You can extract from another full rom 7.0
Second you must have downgrade pack for your region and mobile operator.
Next you must have full rom 6.0 for your region.
You must have all file because you don't want debrand your firmware

Thanks, actually if i want debrand my phone whats the diference? Because I think I don't care...
Also, where can i find all of these files you write about?
I'm really lost with all firmware versions ... Does it matter if my version is EVA L09 C33B363 and i flash stock recovery from another version??
Also, my bootloader is locked, do I have to relock it? Does it even possible??

If you have locked you must unlock again. All file you can take from forum. Debrand it's unlock warranty and sometime you loose your guarantee. But what region you from

Here you have how debrand
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
If you debrand you can then flash stock recovery flash b300 and then b136 and do it wipe in stock recovery.
When you want debrand first you see your cust be c900 and then you must flash stock recovery do it wipe system/data and cache
If you do it your cust change to c432 and then must check your region using dial pad
*#*#2846579#*#* then push 3 and 4
If you see your vendor: hw and country: Europe
You can downgrade to b300 and then to b182
You lose your theme and you see ugly icon then do it wipe system/data and cache in stock recovery
After this you have update to b383 then b386 next to b391 and final to b393 or b394
I have b393

downgrade?

Hi guys
Someone has succeeded with downgrade from oreo to nougat ? I need go to huawei service, to exchange the display, but problem is "relocked bootloader"
So many tutorials here, which to follow for downgrade and have "locked bootloader" ?

You can use HiSuite or install the downgrade firmware through Firmware Finder. It has the normal Nougat version, but in the description it tells that it downgrades.

HiSuite tells me that I have the latest version so.. I cant downgrade from HiSuite, or if i can tell me how to do it please

@yungshadow
As M1chiel said, try with Firmware Finder.
Remember!! Everything is on your own risk!!
Don't know which version you have, but for me this is the roll back firmware...

Let's try. But.. still 0%

If you use proxy option, you have to set proxy in WiFi settings.
localhost and 8080
Then start download and wait until 4-5%, then disable proxy and continue download.

i'm using DNS. Now 11% XD

ok i'm finally have emui 5. Now i must rebrand ?

That I don't know, I already didn't understand why you wanted to downgrade ??

I need to have bootloader status "locked" not "relocked" so i must rebrand to l09 and back to l29 yeah?

Ok guys
I Found a solution.
1. Downgrade from Oreo via FF using B185 (downgrade firmware) thanks
djg269 said:
2. Download some L09 firmware and install via FF
3. After installing I had bootloop (huawei logo, booting system for 10-15 sec and still restarting)
4. Enter eRecovery VOL-UP + POWER > Wipe data and cache
5. After Wipe phone said it's still L29 but now bootloader is locked not relocked
So i'm done now

Glad you got it fixed!!
Sent from my VTR-L09 using XDA Labs

I have a small question - in FF it says to make sure my current version is not "unlocked" - does that mean the bootloader or...? I just want to downgrade to B180 so I can install HuShed. I'm on L29C432B360 currently.

I don't remember this information. Could u send here Screenshoot with that dialog from FF ?

Same screenshot as post #4 -> https://forum.xda-developers.com/showpost.php?p=76556011&postcount=4

I used b185 from b360 with unlocked bootloader and I had no problems.
You should use b185(rollback firmware) and after this will be able toinstall whatever you want

Alright, last question - I have TWRP installed for 8.0. Will this affect the downgrade somehow? Because for example I can't install OTAs with TWRP. I'm sorry I'm kinda new to these kinds of stuff.

I didn't have installed twrp for 8.0 when i Decided to do downgrade so I think it doesn't matter but you can flash stock recovery for 8.0 if u want ofc.
Now i'm on 8.0.0.365(c432) but with official OTA update

Firmware finder not working with EMUI 8.

Hellol, i inatalled before few days official oreo on my Pra-lx1 B360, and now i want to inatall B366 but firmware finder not working, i trying with DNS and proxy, but cant find update in system update. Any solution?

Hi! I don't know which version it's fine for your device and the only way to know it it's to flash it yourself, but i don't recommend you to do that.
Rooting with Magisk is fine on 9.1, just read the latest posts from this thread - > https://forum.xda-developers.com/mate-10/how-to/guide-magisk-root-mate-10-pro-t3886967/page27
As for the roll-back, ut should be possible to do it with this tool and an appropriate roll-back firmware (again, firmware version might depend on your cust/brand).
I recommend you to keep an eye and also read this thread - > https://forum.xda-developers.com/mate-10/how-to/firmware-version-mate-10-t3722019

B303 is not for A09, it's for C800 which is some jp cust.
Most new fw links are not up yet, and since Huawei decided to name all their firmware the same regardless of model its hard to know which is which :/

Success! Updated BLA-L29C432. Thank you!

Great! Soon i will upload a new version that will also flash the patched Magisk ramdisk_recovery and Magisk Manager (this one will be optional, so those who already have it, can skip it).

It worked for me also.

Why is root needed? Unlocked bootloader is not enough?

Nope! Well, it can be done without root too, but it would require twrp in that case.

Somewhere on Huawei's servers! xD

I found a firmware on Easy Firmware, bla-l09 c432 b300 but I don't know if it can be obtained for free or secure, you have nothing?

as stated before, since every update is named the same it's hard to tell which is L09, L29, A09 or AL/TL. AL/TL are easier as VERSION.mbn in UPDATE.zip doesn't have Global strings in it.
From what it seems, if you flash L09 on L29 or vice versa you get endless OTA updates for preload and cust. I don't know if just flashing the cust and preload zips fixes it, but you're free to try if you want.
Here's L09 preload and cust:
Preload: http://update.hicloud.com:8180/TDS/...full/update_full_preload_BLA-L09_hw_eu_R1.zip
Cust: http://update.hicloud.com:8180/TDS/...4//f1/full/update_full_cust_BLA-L09_hw_eu.zip
modified tool to include preload and cust:
https://mega.nz/#!oDR2DYCI!SRQlTq1IriGcEt1Wr--ggrBk7uZ4M_R8OwE6DdvmEEc
Extract and put in the EMUI 9.0 to 9.1 update folder.
Rename cust zip to update_cust.zip and preload to update_preload.zip, put in ZIPS-HERE folder, run modified bat.

Thank you very much, I try very soon. Have any of you done that already?

I did on L29 with L29 preload and cust, no problems.
Base (280955) seem to be the same for both L09 and L29 C432.

Soon i will upload a new tool that will let you flash all the 3 files, so you could wait. Also, a fried of mine is testing on BLA-L09 C432.

Perfect, also because I don't have the Root permissions on the device, and I don't even have twrp. In fact now I have tried and says that it does not find root permissions. Then I did not understand if the phone should be connected from on, in recovery or fastboot?

Tool updated. However, if you don't have root, you can't use it, you must root first.

Okay, I thought it was a tool like the ones we made earlier to install EMUI 9. I'll wait until the new tool is released. : D
