hi,i have a mate 10 pro with stock android 8, unlocked bootloader by flashing unlock key via fastboot. frp unlocked.
stock recovery. not rooted.
bla-l29 c432 131
when i start my mate 10 it says "device cannot be trusted".. before it boots as normal.
Can i lock\relock bootloader and make it go away??
tried:
fastboot oem relock "unlock code"
fastboot oem lock "unlock code"
and it came password failed :\
usb debugging: on
oem unlock: on
flash oem info of sorts?
try: fastboot reboot oem relock?
if i switch oem unlock to off again in developers option and then use commands??
Thanks for help!
FiXed, used adb interface drivers, i tried several until i found 1 that worked
Hi, with mate 8 and mate 9 when you flash officiel firmware he relock bootloader, try this or you can buy credit (4) for relock with DC unlocker.
So... tell me please why you unlock your bootloader if you don't flash twrp or root ??
Dont buy any credit. I Will provide you The solution today.

Thanks, I will try this later and let you know how it goes!
If you only want to relocked your bootloader just use the HWOTA8_Mate 10 tool from the link bellow.
download the tool > go to lock directory > use relock.bat
you'll need to provide your bootloader unlock code to re-locked it.

did you try info.bat? does it restart to fastboot mode so you can see the bootloader status?
what method or tool did you use to unlock de bootloader?

I think you are not having proper mate 10 pro windows drivers. Try following the HWOTA_mate10 guide about preparation, there is a registry fix and you should uninstall HiCare for proper device recognition

Hi, i just started thinking about that, just to be sure since i did not get mtp folder in my computer anymore(win 10)
i switched to my laptop win 8.1,
installed the adb driver manually as adb composite interface in normal mtp\debug phone on.
in fastboot the driver said adb sooner single interface
and then when i am supposed to switch inn to the stock recovery modded with adb support,
i get 3 devies with yellow ! in device manager:
1. huawei- device properties and details then choose bus reported device description: huawei
2. unknown device: - device properties and details then choose bus reported device description: adb interface
3. unknown device: - device properties and details then choose bus reported device description: hdb interface
what should i set these to manually?
i am trying to use "flash update" in HWOTA_mate10 guide and i am on step D run ota.
supposed to switch from fastboot to recovery then the script waits for adb connection
Did you disable oem unlocking in developer options?

Bootloader Unlock not possible - but eRecovery working
@ante0
I have Mate 10 BLA-L09c432 and installed latest Firmware 8.0.0.157 since two days. I updated with official OTA.
Before I had 8.0.0.137 → on that Firmware I read the Bootloader Unlock Code with DC Unlocker → and I got a new Unlock Code.
The originial Unlock Code did not work anymore (Phone was from a friend of mine and bricked and I restored it by FunkyHuawei - and bought it).
I unlocked the Bootloader with the new Code (read by DC) and it worked.
Two days ago I decided to update with OTA. I reflashed the original recovery_ramdisk and ramdisk.img. Update was succesful.
→ I tried to relock the Bootloader (because I am thinking about to sell the phone) → and it does not work! Not with the originial Code, not with the new Code (read on b137)
I did nothing wrong, because this year I unlocked about 40 devices (because I am helping to repair bricked phones from Users of Android Hilfe de) and I know very well how to do. (OEM Unlock enabled, ADB Debugging and USB Debugging enabled, HiSuite HDB disabled, HiSuite on PC closed, ADB and Fastboot working....)
Code:
fastboot oem relock UNLOCKCODE
does not work
But I have no idea yet how to relock the Loader I will try once more - but perhaps you or someone has an idea?
So perhaps I should just be happy to have a unlocked Phone and keep it instead of selling it....
Everything else is working.
And I found out some interesting point → seems Huawei started to bring the Feature of eRecovery even to European Versions of his Phones (from a certain firmware version)
I booted to Huawei eRecovery and "Download latest version and Recovery" is running without FunkyHuawei

Use the DLOAD method with the B150 firmware from androidhost.ru, that should lock (not relock) it.

Then you can use B150 to downgrade with DLOAD method. That should reset the phone and lock the bootloader, to fabric condition.
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

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)

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.

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.

wait you mean i can downgrade it?

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.

Is it possible to lock the bootloader on that phone or not ? If yes ,how ?
EDIT : I tried with fastboot commands oem relock but it didn't work .I removed the root but still need to lock the bootlodaer
Hey, you can flash official firmware into your device and get back to the stock firmware without root. But you can't re-lock the bootloader. I have tried so many command in fastboot and any of em doesn't work.

I was able to remove the root manually so no need to reflash stock frimware,but about bootloader still not successed to lock it even via flash tool BLU option. There should be warning that you can't lock it once its unlocked damn..

Yes indeed. I've tried that too. apparently you can't relock the bootloader in newer devices. Only thing to do right now is, hope that Sony will release some kind of commands to relock the bootloader. Unless there's no other way.

No, an update will not relock the bootloader. As i did for my poco f1 MIUI!
For an Huawei device, it does when you upgrade your device to EMUI10 or above. And the bootloader will not be unlockable via fastboot commands then. Downgrading to EMUI9.x is the only way to reunlock the bootloader currently.

completely irrelevant in this section...
Can anyone help me understand why when my phone gets an android update it can install it without unlocking the bootloader but if I wanted to downgrade my android version I need to unlock it?

With updating, it is by system settings or OTA. However with downgrading, the system cannot let you downgrade by default, as there is no system setting for that - you can unlock the bootloader and then downgrade your version.
To answer your question, YES.
You need to unlock the bootloader to downgrade.
