bootloader unlock on emui 9.1 - Huawei P20 Lite Questions & Answers

Hey everybody, does anybody know if a downgrade is possible from emui 9.1 to 8? Asking because I want to unlock the bootloader but dc unlocker method for obtaining the code has been patched, tried already with dload method without success, pretty sure i used the correct firmware (ANE-LX1 C432).
DLOAD method keeps returning the error "software install failed incompatibility with current version", pretty sure they blocked they possibility to install a lower version of the software, any chance i can force flash from fastboot?

Can anyone list the steps needed to get AOSP/Lineage OS on a clean device?

As there are different steps and threads all over xda as to how to go about rooting redmi note 3 and then installing a custom ROM, I was wondering if someone could list or direct me to the correct working method to unlock bootloader, root, and install a custom ROM.
Note: I haven't done any tampering with the device, no TWRP, no unlocking bootloader via the hack or official method. I have only installed OTA updates sent to the device via Xiaomi.
Current Device Specifications: (Snapdragon)
Android Version: 6.0.1 MMB29M
MIUI Version: MIUI Global 8.5 | Stable 8.5.7.0(MHOMIED)
Kernel Version: 3.10.84-perf-g9105347

Are you suggesting that because the unofficial method is unreliable or because you think I am a beginner?
Both.. official method is simple and with unofficial u may get into firmware probs later while flashing roms which leads to soft/hard brick
Official unlock is recommended to avoid something bad for your device

Thanks, I'll go for the official method, then. But I figure that method takes weeks? How much time did it for your phone?

So, I got the permission from Xiaomi. But, I can't run the Unlock tool on Linux. I tried using VMware Player but the device is still not recognized. Have you had any luck using the official method on Ubuntu?

Forget it if you don't have windows. Xiaomi's unlock tool does not support linux. So you can't go with official method.
And the unofficial method requires a modded fastboot ehich is only available for windows. You can't go with this way too.
So, no way out if you don't have windows.
Also don't think of unlocking it unofficially if you don't have windows because most of the unofficial unlocked devices get locked which again requires the modded fastboot to unlock it.
The last problem, seriously and sadly, doesn't have any other solution
I am unofficially unlocked and few days back i had clean installed ubuntu on my pc but now i am back on windows. Why?? Because my device got locked and i couldn't help but install windows. You have been warned!

Can the device get locked even after installing a custom ROM? What happens when it gets re-locked? ("Soft brick?")

Yes it can. Actually it hapoens mostly when we flash firmwares which have the unmodified emmc_appsboot.mbn file.
When we unlock unofficially this file is modified.
Thus flashing the firmware locks it.
I would not call it softbrick. When that happens you cannot boot anymore. Only fastboot mode is available and it doesn't allow us to flah any files since the device got locked again.
So we again need to go to edl mode which is only accessible by the modified fastboot available only for windows.
Enjoy linux?

Rooting without unlocking bootloader?

Hey,
I was wondering if it's possible to root the mate 10 pro without unlocking the bootloader.
Since huawei is not giving the bootloader codes anymore, and i have the latest updates so dc unlocker isn't an option either.

FOR OTHERS SEEING THIS, IT WILL NOT WORK ON B146 OR GREATER (02 XLOADER). (B148-SP1 being the exception as it has 01 XLOADER)
FOR OTHER CUST THAN C432 CHECK THIS THREAD ON HOW TO CHECK YOUR XLOADER: https://forum.xda-developers.com/mate-10/how-to/beware-bla-l29c432b147-t3817241
Great. You can downgrade to B142 and get unlock code through DC/HCU.
You will need a USB-C to USB-A female OTG cable, or USB-C to Hub and a memory stick (8GB minimum)/sdcard adapter + sdcard (8GB minimum).
Backup your phone with Backup app and internal SD (If you want to of course) as it says the dload will format /data (I'm not sure if it actually does it as I had to format manually from stock recovery, but when I tested I went from B148-SP1 to B142 so the big gap might have caused /data to not want to load correctly).
Download this dload package (BLA-L29C432B142): https://mega.nz/#!vXZRnAbI!pYBwcPATQKyxB-Et74StI-3H7tsytbo2xheIQdTCGKU
Extract zip and go in to the 'Software' folder, copy 'dload' folder to the root of your memory stick/sdcard. (do not extract the update_sd.zip in the dload folder, it's supposed to be zipped)
Plug in memory stick/sdcard in your OTG-cable/Hub and USB-C in your phone and go to dialer app and enter: *#*#2846579#*#*, tap on "4. Software Upgrade", then on "1. SDCard upgrade". Tap on "OK" then install anyway when/if it says "PT Failed".
You can also force dload update by holding power + volume up + volume down with USB OTG/Hub plugged in.
Phone will reboot and start verifying package, this takes a while. Then it will start installing.
If it starts bootlooping after the white Huawei logo, go to stock recovery (Power + volume up) and Factory reset. Booting the first time after downgrade will take a little bit so only factory reset if it takes 5+ mins.
When you are booted use DC/HCU to get unlock code. I had to install drivers from their support section to get it working, else it wouldn't recognize phone.
Alternatively you could probably use Funky Huawei to downgrade to B142, but it's expensive.

Yes, but you will need to find dload firmware for C185.
You should be able to use "BLA-L29C 8.0.0.135(C185)" (Search with that exact text on androidhost.ru), it's from April.
I don't trust the B133, too many versions use B133, but I did download B135 just now and have checked that it is April patch.
For BLA the USB-C to USB A female OTG cable/USB-C hub is required as we don't have any external sd. Placing it on /sdcard/ does nothing

Small question: if you succeed to downgrade from b145 to b142, what do you do after ? Is OTA still working for example ?

OTA will be offered directly, it wanted me to update to B145 again (Which is the latest approved fw for me).
But get unlock code off of DC/HCU before updating, otherwise you'd have to downgrade again

You can't get bootloader unlock code from DC/HCU on B145+, downgrade to B142 and you can.
I did write it in my original post and in the reply to you.

Thank you. Now it's more clear. So if you already have your code before having update to b145, it's not usefull.

Exactly. Well, it would be useful if you never saved your code or rebranded using FH Rebrand tool as well, as that changes your unlock code.
However. If you are on, for example, C432B146 you won't be able to downgrade at all.
Im on .142 now and got my unlock code from dcu. Can i install ota updates without problems with unlocked bootloader? And is there anyway to flashing stock rom without relocking bootloader? One last question if i can update to 145+ after unlocking can i root it too?

You will get updates yes, but to install them normally you need to flash back stock recovery if you have TWRP.
Normally bootloader is not locked after flashing stock firmware, if that's what you mean? Yes, you can root fine on B146ä5+

It prevents getting unlock code from DC/HCU. If you already have code you will be fine (For now anyway)

I have just got my bootloader code for my Mate 10 Pro that came with 145 after downgrading to 142 using your instructions and software

how do i successfully unlock the bootloader without it unlocking again

i am getting a brand new huawei mate 10 pro returning my current brand new one as it got updated to the latest emui which prevents bootloader unlocking, how do i succesfully unlock the bootloader on the next mate 10 pro?
1.how do i prevent it from updating and ruining my chances of unlocking the bootloader Before i have a chance to unlock it, will it force update?
2.how do i keep the bootloader locked will i have to flash some other rom on it to prevent it from updating ota or can i update it ota and keep the bootloader unlocked with twrp or will it be permanently locked if i attempt to ota update after twrp is installed and after the bootloader is unlocked
3.i read that it can restore the default recovery on first boot can anyone explain this to me
since the latest emui prevents the bootloader from being unlocked i only have one chance, and if it somehow updates to the latest emui then it's locked forever, so how do i unlock the bootloader permanently without worrying about it unlocking ever again, i thought that once the bootloader is unlocked and twrp is installed then it will stay like that, but then i read that it can get overitten just with an ota update and once it updates then i can never unlock it again.

1. Set up device, but don't plug in SIM or enable WiFi. Go to settings and check patch level.
Depending on Cust of course, but generally July or later can't be downgraded (If downgrade is needed). This is due to updated bootloader.
If May/June or earlier you should be able to use HCU-client directly to get unlock code.
For example, BLA-L29C432B145 (June) can be downgraded to B142 (May) where HCU works. This is using dload firmware from androidhost.ru (requires an OTG-cable and USB-stick 8gb min or a OTG usb hub and USB-stick 8gb min).
B146+ can't be downgraded to old bootloader due to updated bootloader.
2. When you have the unlock code you can use it, always, no matter what firmware (At least as it is now, this might change in the future)
Firmware don't normally lock bootloader.
3. To restore stock recovery you would either:
Extract it from your firmwares update.app, acquired from firmware finder. This is extracted using Huawei Update Extractor.
Stock recovery is named recovery_ramdisk and can be flashed through fastboot.
OR
You can 'dd' erecovery_ramdisk to recovery_ramdisk (both partitions are the same, different 'entry' points). This is using terminal in TWRP
dd if=/dev/block/bootdevice/by-name/erecovery_ramdisk of=/dev/block/bootdevice/by-name/recovery_ramdisk
I would suggest using the update.app approach if you're not comfortable using terminal. 'dd' is a potentially dangerous command.
But your device should ship with an already HCU compatible firmware, so you should be able to get code right away, as long as you don't connect to the internet first.

can i set it up without a Connection? from what i remember setting it up the first time it forced me to connect to the internet, as for unlocking that seems really complicated, from what i saw i can use dc unlocker with the click of a few buttons so i don't quite understand these methods, so you mean this is better than dc unlocker, does that mean once i get the code i can update emui and relock the bootloader and then unlock it? no need for any software or anything once i have the code then it's like an official code so i never have to worry about not being able to unlock the bootloader again can i then unlock the bootloader no matter how new emui if i want, and what firmware will it have if it comes brand new should it have the firmware it shipped with on release?
let's say the phone comes with Before may security patch can i then easily just get the code without much complication and then it's the same code as if i were to get it directly from huawei meaning i don't have to worry about updating emui and having the bootloader locked permanently? this is all news to me as i thought you needed to use dc unlocker as a workaround and that this only works on older emui meaning if i unlock the bootloader update emui then it's locked forever.

Hcu-Client is made by DC-Unlocker, but it works for newer phones. Its the same procedure as using DC-Unlocker, and uses the same credits. Just follow the instructions found in the program.
The downgrade would only be needed it your firmware is higher than the supported ones, and still on old bootloader.
I can't say for sure the unlock code will work for all eternity, but at least for now it will work after you update (and if phone for some reason locks after update).
If it works or not on future firmware is up to Huawei. My phone stayed unlocked when flashing Pie beta anyway....
When you have the code you it will be like the official one, so keep it somewhere safe.
I'm pretty sure you can skip through the whole set up without connecting to the Internet.
I can't remember what firmware my phone came with, it might have been on C432B127 or C432B129...
DC unlocker/HCU is only to get the unlock code as Huawei closed their site to get it. You can safely update after getting it.

oh so no need for a Cable or anything after i received the code, once i received it on the appropriate firmware then i can update emui, this means anything i do doesn't do anything to the phone itself, i don't need to do any modification on my phone i just use it to get the code then i update emui like normal and then when i feel like it i unlock the bootloader with the code, so i can get the code and just forget about it afterwards unless huweai invalidates it in the future?
simply put
1.i unbox the phone and set it up with no sim card or internet skip all logins
2.i connect it to a pc and get the code through hcu however that is done
3. i reset the phone and set it up like i normally would with internet and a simcard and then update it ota
then when i feel like it i can unlock the bootloader on the newest firmware and then install a custom rom
Hello guys, I need to read bootloader code in my mate 10 pro with dc-unlocker but they write in the site "Huawei Mate 10 Pro BLA-xxx upgraded to Android 8x not supported".. what do they main? Mate 10 pro was launched with android 8.0

It means it's not supported since May/June. I guess they just write that so they don't have to investigate into which firmware exactly.
It works on May patch firmware and earlier. Some cust even works on June.
Since your signature is Italian I guess you have C432?
If so, last build it worked on was B142. If you're on B145 you can downgrade to B142. If you're on B146 or later you can't get unlock code. (at least for now)

It most likely will be then. If its B133 or even B135 it should work with DC out of the box. Just don't update before getting code

If DC-Unlocker doesn't work, use HCU-client. I can't remember if Mate 10 Pro is too new for DC-unlocker.
It's the same credits anyway, and it won't use credits if phone is not supported in DC-unlocker (You won't get the Bootloader code option anyway).
It may ask you to factory reset in HCU to get code, if it does just comply.
You will need 4 credits, which equals $4
i spoke to the developers of dc unlocker i was told they have no idea if the code will work after emui is updated, they suggest i unlock the bootloader as soon as i receive the code.

If DC-Unlocker doesn't work, use HCU-client. I can't remember if Mate 10 Pro is too new for DC-unlocker.
It's the same credits anyway, and it won't use credits if phone is not supported in DC-unlocker (You won't get the Bootloader code option anyway).
It may ask you to factory reset in HCU to get code, if it does just comply.
You will need 4 credits, which equals $4

Yes, it should work forever. I say should because it's Huawei and you never know if they decide to lock all unlocked phones and make the unlock codes invalid....

It should work in updated EMUI, atleast in Oreo.
What Huawei did, what I found out anyway, that made unlock code generation not working anymore is changing the key needed to generate it.
It's the same with the backdoor they use, it needs a new key to work. So technically all old unlock codes should work as the end result when generating an unlock code would be the same regardless of what key is needed to generate it. I guess anyway.

B145?
If so you have to downgrade to B142, firmware is available on androidhost.ru.
You will also need an otg cable and a memory stick/usb adapter and minimum 8gb memory. (Samsungs USB-C to USB-A works fine for this if you happen to have one)
Or a USB hub.
Then extract your downloaded firmware zip, just cut and paste "sd_update" folder to external memory stick and start phone in dload mode.
There are instructions that come with the firmware on how you flash it (dload mode, folder structure etc.)
External memory is needed as Mate 10 Pro can't read internal while in recovery.
tried Reading bootloader code
2018-09-24 18:33:41.333 Autodetect COM port and phone type start!

Read bootloader code fail!
Not supported/unknown chipset!
so i guess thats it then?
wait you mean i can downgrade it?
bla l29 8.0.0.145 c432
and yeah i have that otg samsung adapter
so i download the firmware put the folder in the root of the usb stick and then simply downgrade?, will it still work after i attempted to get the bootloader code right now?

Yes, just downgrade, get the unlock code and then unlock. It doesn't matter that you tried to get the code while on B145.
would you mind giving the most stupid easy to understand guide just to make it simpler for me so you mean it is certain i can do this.

How I rooted my Huawei P10 late 2018 (cost €4)

Here's just a quick guide of how I just successfully rooted my P10 (from android nougat)
Use this file (https://drive.google.com/open?id=1c1iQBvvP7zTUiKz5PZmlJUH5DKBxxC3L)
It has everything you need inside in one package. (I havent anything to do with the development of any of the tools, this is just my compilement of them)
1. BACK UP
Back up everything you can on you phone to your pc
2.Drivers
Easiest was is to install Huawei's HuSuite otherwise do a manual driver install
3.Get bootloader unlock code
This will cost 4eur but is now the only way to get the code since Huawei stopped providing the codes. I can verify DC unlocker are legit, their tools are scary powerful and well worth the cost. Follow the below tutorial for this.
https://www.dc-unlocker.com/how-to-read-huawei-bootloader-unlock-code
4.Unlock the bootloader
On the phone enable developer mode (look this up its easy) and enable usb debugging and oem unlock. Then plug the phone into your pc and run cmd.exe inside the set folder. Enter the command without quotes "adb reboot bootloader". This will restart the phone in bootloader mode. Next enter the command "fastboot oem unlock CODE" with your code that you got from dc unlocker. This will restart the phone from factory so you will need to do a quick set up and enable developer settings and usb debigging again.
5. Installing custom recovery
Enter the bootloader mode again with "adb reboot bootloader". Then from the bootloader mode enter the command "fastboot flash recovery twrp-3.1.1-0-vtr.img" this will install twrp recovery.
6. Installing Magisk root
Copy the zip file Magisk-v17.1.zip onto an sd card and insert into the phone.
Restart the phone into system again and use "adb reboot recovery". This will start the phone into twrp recovery mode. From here go to install, navigate to the zip and install it.
7.Finishing
Then boot the phone and Magisk manager should be installed on your now rooted phone for managing you super user and root.
Any questions or help needed message me, or my email is in my set folder.
@Jyndon use MEGA or zip files and attach it to the thread. People won't download from this, since they need premium feature to download folder.
Yeah bro I need it plz

What is Android version on your P10? My one is Oreo 8.0 and DC-Unlocker did not work. It showed "unknown error 375"

I think we are out of luck I was just asked for 30 euros to get the bootloader unlocked as I am also on 8.0
On DC-Unlocker page it says:
Huawei P10 VTR-xxx upgraded to Android 8x not supported
Huawei P10 plus VKY-xxx upgraded to Android 8x not supported
Not sure if downgrading and then unlocking would make sense...

Hi,
it's possible downgrading to previous version or to Nougat without unlocking bootloader first? Pheraps you mean forcing update via microsd slot?
Thank you

Here is what I know so far:
1. You do not necessary to be on Nougat to unlock the bootloader, you should be able to unlock it if your firmware is before June patch
2. If you are on firmware after June patch, you would first need to rollback/downgrade to pre June firmware by finding previous firmware
3. Rolling back from after June patch to previous firmware might brick your phone
Currently, I did not find a way to unlock the bootloader on C654B327 as I cannot find any pre June firmware for my branding (C654) and rebranding to some other (C432) cannot be done without unlocked bootloader. And so far I did not hear of anyone downgrading and unlocking from C654B327 so I am a bit afraid I could brick my phone.
Guess I will wait and see if there are any good news in the future...

I'm not suggesting to unlock the bootloader with DC, you should be able to do that normally with adb the same as you would on nougat

I was on nougat when I wrote this guide. Maybe try rolling back to android 7.0 to get the bootloader code then upgrade again after. To do this I'm assuming you might be able to use some dload method perhaps.

True, if he hasn't latest security patch installed. With patch from Dec 2018 it seems that Huawei introduced something new so you can't roll back even with dload method

In that case you could always send an email to DC to see if they are working to update it to work for 8.0. They seem pretty helpful and responsive from when I've contacted them before so I'm sure they might be able to offer some information.

hi,
I tought so but I did downgrading with HiSuite and then locked all requirements for DC Unlocker and I've got my bootloader unlock code now to do anything !!!!
It took a while and lot of nerves but at the end you should do step by step all points which was mentioned in the begining of this thread.
in case of dc-unlocker problems try to use other usb port (other than usually you use for connecting the phone to computer)

Hello,
Hisuite method does not work with latest firmware/security patch. Tried many times, but no option to downgrade appears. It looks like Huawei would prevents to let us downgrade as they stated.

Hey i bought 4 credits and when i try to read bootloader code i get "unknown error (375)". Maybe you know why?

What? Where? If you mean DC unlocker tool maybe your device isn't supported, but you should ask them not here.
@justinas2003 which software version and security patch you got? Here some additional info:

So I should downgrade through HiSuite?

Downgrading the Honor 9 Lite(LLD-L31 8.0.0.143) to older version?

Does anybody know or is it even possible to downgrade the firmware to older one because Huawei does not anymore give out the bootloader key and DC Unlocker is unable to get the key for the bootloader on the newest update because security patch.
So i have locked bootloader so i need to downgrade the system in the way of Huawei "meant to do it".
