Hi there.
I decided to post a guide on how to downgrade and unlock the bootloader of "Huawei P Smart"
I've seen a lot of people now knowing how to downgrade, to a unlockable firmware.
Please note that "Bootloader unlocking" costs 4€ using this method!
I do not take responsibility for any phone that Is bricked or damaged In any way, by using this guide!

Required Stuff:
Huawei P Smart (any model)
Charging Cable
Windows PC
DC-Unlocker (easily found on google)
Firmware Finder Huawei (found on Play Store)
And of course 4€ If you are unlocking bootloader.

Downgrading
Here Is my current firmware:
KdP6Nzy.jpg


First of all we need Firmware Finder:
sMnW6fl.jpg


After that we open It and It should have a button with your phone model.
In my case I am using a FIG-LX1
xwzLtnJ.jpg


On the list of firmware's I selected FIG-LX1C432B129 (8.0.0.129)
Ko64JU9.jpg


Now you should get to another menu and select the eRecovery option.

Then you should get this handy message with a DNS Address you need to enter In your Router.
cNYgc5s.jpg


In my case I found It under basic settings, and my default gateway was 192.168.0.1

After this Is done, disconnect, and reconnect to your WiFi on the phone.
Then press the "Open QUERY" button, on the same page as we got the DNS address.
Make sure the website looks like this.

Now press next, and you should get a "check availability" button
Should say this.

Press OK and press next.
Now press the "Register Update button.
Should come with a small popup saying that you registered It.

Now press next, and press OK on the second pop-up.
Now you need to power down your device.
Then you simply Insert the charger and immediately start holding volume up.
Release once you see this screen.
Press the "Download latest Version" button.

Then you should get into this screen.
Here you just need to press the "Download and Recovery"
743v767.jpg


It should connect to WiFi, and should start downloading like this.
Remember to check that It Is the 8.0.0.129(C432) Firmware!

After this Is done you should get into a bootloop.
This Is easily fixed by holding Power + Volume UP.
Now you should be In normal recovery.
Just press "Wipe Cache" and then "Factory Reset"
T0grLHU.jpg


Now your phone will reset, and should boot into first time setup.
No need to set It up completely If you are going to unlock bootloader!
Here Is my Build Number after his procedure.

If your phone Is like mine, congratz on the Downgrade :cool:

Bootloader Unlock
Now for the bootloader unlocking.
As mentioned before you will need 4€ for this procedure!

First of all.
enable developer options. (press Build Number 7 times)
Then make sure USB Debugging, and OEM Unlock Is enabled!

Q72HZnM.jpg


Now we need to go to the dial pad, and enter In the number: *#*#2846579#*#*
It should get you to a menu like this one:
sfFt9uR.jpg


Once in that menu, go Into "Background Settings" and select "USB Port Settings"
In there select "Manufacture Mode"
AklbQOn.jpg


Now plug In your USB, and open up, DC-Unlocker.
On the left Select "Huawei Phone", and press the Left button.
Then It should detect your phone like this:
4Zp2AGY.png


Now you need to press the "Buy Credits" button, and go through their form.
Remember to buy 4 credits (he cost of bootloader code).
Even easier, you can get the DC-Unlocker app from the Play Store, and get credits through that.
They will send you a password for your account, once payment received.
Now press the "Server" Tab and login.
Then go to "Unlocking tab" and press "Read Bootloader Code"
It should give you your bootloader code.

Now comes the easy part!
Go Into the folder where you downloaded DC-Unlocker
In the address bar, type "CMD" (without the "") and press Enter.
You should get command prompt up like this.
CCT3xdv.png

Now you simply enter these commands.
adb devices. (make sure your phone Is listed)
adb reboot bootloader
fastboot devices (make sure device Is listed)
fastboot oem unlock *KEY* (replace *KEY* with your bootloader code from DC-Unlocker.
CCT3xdv.png


now you should see a "Yes or No" screen on your phone.
Press Vol up/down move and Power to select.
Eg8iGXI.jpg


Now your phone will reboot, and automatically reset Itself.
All data will be erased.
After this It should pop-up like this, and then boot Into Android.

If everything went according to plan.
You should be unlocked and ready to flash some Roms :cool:
I recommend flashing OpenKirin roms, since they are specific for this chipset!

Sorry for the VERY big pictures, and hope you could use this tutorial :fingers-crossed:

Is it okay to install firmware for the FIG-LX2ZAFC185 on my FIG-LX2C185? Firmware Finder can't find any software for my device. Edit: Yes it's okay, I had no problems!

Also, I can't put my phone into Manufacture mode; when I enter the dial code the dialer just resets :/ Edit: After downgrading Firmware it worked

Thanks so much for the guide man!

Nova 2

Hello,

Thank you so much for your tuto.
I have a problem with firmware finder. I'd like to downgrade my Huawei Nova 2 to Nougat so I chose one of the firmware proposed with EMUI 5. But when I click on "check availibility", It send me to the first page where I have to chose my phone model.
Please help me... I really need to unlock my bootloader, I thought I would succeed with your tuto I was so close...
Tell me if you have some suggestions.

Thank you so much.

Sorry for late reply, currently working on some stuff :)
I don't have a Huawei Nova 2 so I am not the best to ask :(
This guide with bootloader unlock is intended for Huawei P Smart.
That being said try: reinstalling the app, and select the earliest firmware for the phone :)

I can't downgrade at Erecovery it says get download information failed.

use only full OTA stock update you downloaded from internet on pc using chrome but download from creators of firmware finder team MT... then global search in XDA for hurupdater.. follow instructions to apply stock rom sd card.. doesnt matter if it's a downgrade it will flash

When i tried downgrade not working. Is there any new solution?
I paid a guy who did it all for me downgrade and bootloader £9, if you can downgrade yourself it's only 5£ for bootloader unlock. I've been around a while but I class myself as a noob. The website is called MOS ministry of solutions. However now I've been there done unlock, root, twrp which was only last week I'd say it's a waste of time, unless you really know what your doing but even then these guys in here have gone full circle back to stock. I've gone full circle not just to stock, removed root and back to stock recovery. Only thing I took from root was I managed to make the speaker louder as one of my motivations for root was viper which don't work on Huawei or specifically psmart for sure. So sorry to say this but at this stage there isn't much development for psmart which is because Huawei have made it difficult. I'd advise against mods of any kind at this stage. I was rooted less than a week and multiple resets, soft bricks and not much success with magisk modules that count like viper.

I confirm that this metod works.

1. I downloaded from androidhost.ru:

Huawei P Smart Figo-L31 FIG-L31 FIG-LX1 8.0.0.128a(C432) Firmware Android 8.0.0 EMUI 8.0.0 05014XMW androidhost.ru.zip.

2. I unpacket the zip file
3. I copyed dload folder from archive to sdcard (withouth change anything)
4. I opened the phone Huawei P Smart fig-lx1 (C432) in force upgrade mode
5. The new (OLD) firmware was installed (downgraded OK)
6. Then, with dc unlocker I readed the bootloader and rooted my phone

Thanks, santalimi for share name russian website android host!
This is the exact method I used and it worked perfectly, I second this!

    I would die first before I give any cent, or scrap of personal info to a random asshole that provides what is mine in the first place! Huawey are despicable, but the people behind the unlocker program are worse. They should be doing that service for free, not take advantage of people. They should be giving away the code as a big middle finger to Huawey, and be the hero in this case. Maybe and have a donate button underneath, and accept generosity from people, instead of random.
    **** that! I'll stick with ads till the real way is found.

    Well, I blocked all ads by using a raspberry pi and passing my lan trafic through it's DHCP
    I guess in one way I should thank the poster, you made me create an ad block shield around my house.
    I'm still pissed off not being able to root my phone, but I'll never spend a dime to support thieves.
    I wish more people understood the sentiment, and never even considered giving them money that way.
