Hello, yes c636. I tried rollback. But dload does not allow. It says not compatible. As i analyzed, im sure i missed full hw. From hisuite during ulpate to B320. Do you think flashing full hw from B320 will do? If it will. Can you please upload me full hw? And fmash thru dload? I cant flash image file. Sys. Boot, recovery wont do. Im not rooted.

Ok. What file to flash? The rollback? The B300 southern east asia roll back? Then if successful should better off flash ahead the least version stock right? Should i then proceed with dload process or hisuite for a stock fw? What are the risk in flshing thru dc. With 'test' build? i really appreciate your effort sharing your expertise and knowledge.

U have to use rollback file from huawei website
then dowangrade using any full M file
so bootloader and FRP will reset to default
then update back to 7
All steps : dload

Install b182 (still MM) and you should then receive OTA upgrades to b38x, b39x (Nougat)

I still don't understand why you don't 'like' OTAs. In System Update, Settings, you can always choose Full Update instead of default Differential. And you can force afterwards Factory Reset if you think you need.
b386 is the last flashable by DLOAD. Btw, I was going back and forth through diff stock and rooted and custom ROMs, rollbacks, OTAs, and never had any error in installations. There are many threads with excellent info and guides, you must read and follow because in diff situations methods might be different. DLOAD is not always applicable

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 ??

Can't do anything with this trash device, even TWRP fails to install. What a waste of money!

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

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

Version downgrade

I have searched everywhere but I didn't find a reply to my question.
A couple of days ago I have updated my phone LLD-L31 to the version 8.0.0.132 through Firmware Finder (it worked for me with proxy method) then I decided to revert back to the previous version 8.0.0.131. So I started reading guides to install a firmware on Huawei/Honor devices, I have downloaded the FullOTA package version 8.0.0.131 with Firmware Finder, placed it in the folder dload on my SDcard and started the intstallation in the project menu (accessible digiting *#*#2846579#*#* in the dialer), it started but suddenly it ended with a message "installation failed".
So my question is: how can i revert to the previous version of the software (or to the out of the box firmware installed on my device)?

You should have an option to downgrade in the about section/ the update menu of your phone if you did it right.
Otherwise you may need to use the HuRupdater Method.

Thanks for your reply!
I don't have this option, but if I remember well I hadn't it also in the previous version of the firmware.
So i can't install a previous version of the firmware simply downloading it an putting into dload folder of the SDcard?

Can you please specify why do you want to roll back?
Because most people just wanna upgrade to a newer version.Newwr versions will have better stability so it's recommended to keep the latest version unless you have some bugs.
I honestly don't know why the dload method doesn't work, seems that it doesn't work for most people.
I think you'll be able to roll back using HuRupdater. But that'll mean you'll have to unlock bootloader and flash twrp first. Then you can go all stock from there.
Here's a guide to the HuRupdater from @zxz0O0

After installing the version 132 I asked the technical support through HiCare and they told me that installing firmware with Firmware Finder could void warranty so I decided to revert to the previous firmware and wait for regular OTA by Huawei.

I'm not sure but I think you are on the latest build for your varient now so you won't be getting any updates untill a next build comes in.
I don't think you'll be able to roll back without the firmwares from firmware finder as you don't have an option to roll back.
The best option now would be to just wait for the next official build(might come soon as a small ota which has security patches) and then check if you are facing any issues installing which you won't as you are not rooted and dosent have an unlocked bootloader. So don't worry ?

Want to downgrade my honor 9 lite
After some update the theme engine crashed. Themes can no longer change the notiifcation bar icons and shortcuts icons.

Downgrading version Problem
I used firmware finder and dns method to downgrade my honor 9 lite and while i register update on firware finder and opens hisuite for update it is saying u r on already the latest version
Plz help me with downgrading my version 9 to 8

So is Oreo update possible?

So dload method is horrible and only works a handful of times, always failing, and Honor debranding for Oreo beta is a mess, and also has a lot of bugs and problems during installation. Is there any easy way to install Oreo, through TWRP for example, having a normal pralx1 B197 C432 single sim? Also, assuming a method works, how could I downgrade to Nougat in case Oreo fails for some reason?
thanks in advance!

Didn't you get an official update already? I got my Oreo update three weeks ago.

Try with HuRUpdater easy to use

I don't know if I have OTA available, even if I have stock rom, because my updater is broken, since i have TWRP and it goes into that instead of eRecovery to install the update.
