Hi! I am bringing this thread to life because I got many requests for a guide to unlock bootloader on LG K10 MS428, K425 & MTK Variants.
Requirements:
ADB, Fastboot, ADB/Fastboot Drivers & LG Drivers.
Settings > Developer Options > USB Debugging (Enabled) > Enable OEM Unlock (Enabled)
(1) Connect your phone to your computer using USB. If you see a prompt for "RSA Fingerprint". Select OK.
(2) Open Command Prompt (Windows) OR Terminal (Linux).
(3) Type "adb reboot bootloader". Your phone reboots into fastboot.
(4) Type "fastboot oem unlock" or "fastboot flashing unlock"
(5) Type "fastboot reboot".
Your phone's bootloader is unlocked!

So how do you think i will convey the instructions to members? Do you want them to search each and every forum and post just to get their bootloader unlocked? What's wrong in being more organized?

It doesn't work anyway.
Probably problem is in version of my device. It is LGK420N.
Can k428 unlock?
Lg k10 (K428). Can it unlock?
LG k10 ms428 carrier MetroPCS processor Qualcomm
First I wanted to say thank you for everyone helping out! I really appreciate all the hard work everyone puts in so thank you..
With that being said comma I am still very confused about the LG K10 Metro PCS Qualcomm variant.
Read and reread the red over and over and I still haven't found a screenshot showing that it has been rooted properly.
But not only that custom recovery is also needed.
If anyone has a link or any information on how to flash custom recovery and to obtain root I would greatly appreciate it.

Thank you said one more question I attached a screenshot of the version of vermer I am currently using. Do I have to flash firmware version c? even though my security update is below the specified date in the link you sent?
I haven't updated the security patch when it came out. Thanks once again you've done a lot I really appreciate it

Is there anyway to do this without a pc like maybe using Flashfire. I currently do not have a pc but I'm looking to root my ms428 LG K10 from MetroPCS running Android 7.0 with may 1 2017 security patch any suggestions.
TAKE CARE OF YOUR ARCHIVES, I could unlock the bootloader but then when I started it I lost my info.

It already notifies you just before you approve the confirmation. Take care of yourself and do not apply the whole steps you see on the computer screen. Try looking at the screen of your device as well!

So I got my pixel XL from verizon today hoping that it would be like the nexus6 where they were nice and didn't lock it down. Well I was wrong. The good part is this. They (Verizon) have just disabled fastboot commands/connection. So we need to get that changed and we "should" be good. So if anyone has any ideas where to start on this feel free to chime in.

Step 1: Temp root
Step 2: Change buildprop
Step 3: enable oem unlocking from settings (or enable it in buildprop)

ok i got it
I needed to update my drivers.....SO it all comes down to that box in developer options.
Firstly i am using this TOOL
I did a factory reset on my phone and settings > developer options > screen lock is off, enable oem unlock is on and USB debugging is on. When i go to the bootloader the "PHONE Locked" text is STILL green!
The tool shows this when i try to unlock the bootloader, the text "FRP Unlock" is red.
Try to unlock it via fastboot. Reboot your phone to bootloader mode, connect it to pc, open fastboot on pc and type in
fastboot oem unlock (and type here your unlock code without brackets)

Do you have the correct drivers installed? Is it at least recognised in windows device manager?

It seems that it's installed correctly. Even if you type "fastboot devices" in fastboot, it isn't recognised?

Your problem isn't in adb mode. It is in fastboot mode that probably you have corrupted drivers. (like kedacom usb device).
So you need to correct it, look these pictures and try to update software drivers manually (don't reed text cause in italian but it's the same process):
1) http://prnt.sc/d0t8m1
2) http://prnt.sc/d0t9ui
3) http://prnt.sc/d0ta8h
4) http://prnt.sc/d0tatf
It looks like this now https://imgur.com/a/oRzoO, when i type fastboot into CMD it comes up with a bunch of stuff so its correctly installed. fastboot isnt recognising my phone.

i cannot im affraid. Bootloader is locked, and i cannot unlock it.
When i try to unlock it says that i need to enable oem unlock but i have no android installed..
Actually it's not qhsusb_bulk mode that you need, you need QDloader mode which can be accessed through the qhsusb_bulk mode. If you run Windows,
#1. CMD(admin)
#2. bcdedit.exe -set load options
DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -TESTSIGNING ON
#3. Reboot your computer keeping your phone connected to the computer
#4. On booting go to device manager
#5. You should see a new device entry with QHSUSB_BULK under Qualcomm devices(or any other Qualcomm entry)
#6. This is the QHSUSB_BULK mode that you can use to get into QDloader mode using appropriate drivers, as in the links I posted.
I'll look for more info, if I can help you?

Try going through the process of unlocking bootloader....and I have a feeling that it will work, since you don't need to boot your phone for unlocking the bootloader. You can find guides for that....

ill try the steps. But the unlocking is not going to work because the first step is use
Code:

Did you manage to fix it?
Did you manage to get your phone fixed? Mine is doing the same thing you said, I can not flash anything, and the "qualcomm unbrick" guides do not work for me, I dont see any Qualcom Loader in my Devices Manager, but I do see an Android Device when I plug it to my pc.
I can only get to fastboot mode, can not flash anything, my bootloader is locked, and it trhows the same error (read datablock error) when I try to unlock it.
Thanks in advance

Could you solve the problem friend? I am also in that situation, greetings
Try to choose QCOM mode in a bootloader
I too had the same problem and solved it.
You can't reboot into bootloader so can't flash stock firmware. I had the same problem and was able to solve it using few tutorials.
Here is a youtube video to solve this problem: https://www.youtube.com/watch?v=m2NqpY6X-X4
Watch the entire video. He had a proper running device and then purposely bricked his device to bring into the same state as your device.
Then he solved it.
Here is the xda thread that was used to create the above video: https://forum.xda-developers.com/moto-g4-plus/help/solved-unbrick-hard-bricked-dead-t3585016
The above video was made using this xda thread and I am not the owner of the video or the thread.
I would suggest watch the video and follow it as its more continent.
Note: there was a step in the above mentioned thread which was to be done. I did it and faced problem (the computer then didn't even recognize the device as qhsusb_bulk and showed "usb device not recognized"). Had to reset my pc and then skipped that step. That step is also skipped in he youtube video.
These are the two lines which I skipped writing in cmd and it worked:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

I had to buy another phone! I just couldn't fix it in any way.
I even took it to a guy who works fixing phones, and he said it had the motherboard bricked! And there's no solution for that, other than buying another board (expensive!!)
sorry for the long talk but i am so confused, i hope anyone can help
i tried alot of custom roms, all of them load the logo then restart and never stop, i asked before but no one could offer solution.
i felt so stupid everyone was replying thanks thanks works works works
i found in asus forum someone saying the problem is with the baseband i found (modem.bin modemst1.bin modemst2.bin) for my model and flashed a rom (OCT-N-WEEKLY-20170811-0914-Z00L.zip) somehow booted with no wifi or imei when i restarted it never boot again , flashed again as well but also never boot again
so i decided to reinstalled the stock rom again, to find no signal, wifi, imei, and Bluetooth dead, i pulled the firmware files from another device and pushed to mine, everything works now but i can only make calls but can't receive, data connection not working and imei still 0, i rooted the devices and tried to write the imei again but never worked, i tried to enable the diag mode but never enabled, tried a lot of times with diff versions of stock roms, then i tried to downgrade to stock lolipop maybe it will work (flashed successfully) but never pass boot animation.
now i am only stuck with Marshmallow can't receive calls or enable data connections !!!
any suggestions please
list of everything i tried

thanks for answering, but QPST requires enabling diag mode which i tried several times with two diff devices both rooted bootloader unlocked, debugging enabled and didn't work
Use minimal adb and fastboot tool.
Open your phone usb debugging
Enter commands
"adb shell"
"su"
(Now give root access on phone screen)
"setprop sys.usb.config diag,adb"
Diag port enabled...
Note - 1. phone must be rooted
2. Enter commands without quotes
3. After entered every commands press enter
4. Adb driver must be installed on your PC/laptop.

Clarifications:
No matter the version of Android that our Smartphone has, the procedure is the same.
When unlocking the bootloadrer all our personal data and applications of the smartphone will be erased, I recommend making a backup of our personal files.
Requirements:
We will obviously need our Xiaomi Mi A2 and have a PC.
Steps:
1-Preparing the smartphone
Enable oem debugging and usb debugging:
Open Setting> System> About Phone> Press where it says "Buil Number" until you enable the developer options. Let's go back a step, and we will see that within the options of "System" a new one will appear, called "Developer options"; we enter it, and within the options we have to enable "OEM unlocking" and "USB debugging".
Then we will proceed to turn off our smartphone.
Once turned off, we will press at the same time volume - and power for about 5 seconds, until our cell phone turns on (this in order to enter the fastboot mode), if everything was done correctly, the following image will appear on your screen.

We connect the cell phone to the PC
2-Preparing the PC
Install Drivers
For me the best way to install the drivers is as follows (if you know a better way I accept suggestions)
Download the tool My Unlock
Extract the zip file into a new folder on our pc, double click to execute the file called "miflash_unlock", we will open the application, top right of it will be the "wheel" of settings , we click on it to enter; a new window is displayed, and where it says "My Usb Driver" we click on "Check"; a "Connect your device again" notice will appear, we disconnect and connect our cell phone to the PC again, and we will have the driver installed.
We can close, we do not need this app anymore
Install the adb tools on the PC
Download the installer
1. Run it (Require administrator privileges)
2. Press Y / Yes to install ADB and Fastboot or N / No to skip
3. Press Y / Yes to install ADB system-wide or N / No for current user only
4. Press Y / Yes to install Drivers or N / No to skip
5. Continue Driver installation
6. 15 seconds passed - finished!
3-Finally we will proceed to unlock the bootloader
Download the following folder "UNLOCK BOOTLOADER XIAOMI MI A2"
We enter in it, we will find a .bat file called "unlock auto" (we make sure to have our smartphone connected to the PC in fastboot mode) we double click to execute it.
Immediately on our cell phone will appear a warning on the screen about which we are going to unblock the bootloader. And pressing twice volume -, select the option "unlock the bootloader", then press the button "power" and our smartphone will restart a couple of times, all our information will be erased and we will have the bootloader unlocked.
Suggestion:
Once the bootloader is unlocked, I advise you to turn off your smartphone again and enter fastboot mode again, go back to the "UNLOCK BOOTLOADER XIAOMI MI A2" folder and double-click the .bat file called "flash unlock critical", this with the purpose, that when we want to restore our smartphone and flash the stock firmware we have no problems.
Here I leave a video on YouTube that is a visual guide to the procedure.

That's what i thought. But nope. It failed upon unlocking.. Re-flashed stock (from stock) and then locked bootloader, passed safety net
