This is 2 months late, but if you're still looking for a possible solution, this is what I did:
1.) Download the tools you need here: https://developer.android.com/studio/releases/platform-tools/ and extract
2.) Install LG United Mobile Drivers from here: https://lg-united-mobile-driver.en.lo4d.com/. I recommend uninstalling previously installed LG G4 drivers from Device Manager and then reinstall from that page. You may need to install additional drivers once you connect your G4 to your computer.
3.) In Developer Options, make sure you have "Enable OEM unlock" checked and "USB Debugging"
4.) Open a command prompt in the tools directory (hold shift, right-click inside the folder, and click "open command prompt here." If you've authorized your device to be recognized by your computer (two prompts should popup: one to allow USB connection and another to allow USB debugging), your device should be listed if you enter the command "adb devices"
5. Enter "adb reboot bootloader"
6. Once the phone has rebooted into the bootloader, you should be at the stage where you get the text on your phone, as you described. Enter "fastboot oem unlock"
7. Check if you've unlocked the bootloader: "fastboot getvar unlocked"
8. If successful, you can then go on to flash TWRP onto the recovery partition and root your phone by flashing Magisk from there.

Are you using a usb 2.0 or 3.0 port? You should use a 2.0 port.
Also try disabling windows 10 driver signature enforcement.
SOLVED..
I was on a win7 computer... never worked somehow
switched to a Win10
and worked like a charm...
twrp installed and rooted
using this guide

Welcome to the guide of relocking your bootloader.
First you need to get 2 things:
1.) Minimal Adb & Fastboot HERE
2.)Your bootloader unlock code HERE
3.) [Optional] USB drivers (In case windows didn't already auto installed them)
Ok so now onto the tutorial:
MAKE SURE YOU ARE NOT ROOTED, NOT RUNNING A CUSTOM ROM, NOT USING A CUSTOM RECOVERY, BASICALLY BE ON FULL STOCK!
Procedure::
1.) Power off your phone and connect it in fastboot mode by holding the volume down button and plugging in the usb cable to the pc at the same time.
2.) Make sure your FRP is unlocked, if not, boot into the system -> all the way down to the last option -> Developer options -> OEM Unlocking
3.) Now open your adb & fastboot command prompt and type the following:
fastboot oem relock <your bootloader code>
Click to expand...
Click to collapse
Your phone will now perform a factory reset and then your bootloader will be relocked.

Hi everyone, I recently decided to root my One Power XT1942-2 using Magisk. However, I'm stuck on the first step of unlocking the bootloader. The guides I've seen on this forum have basically been the following simple steps:
1. fastboot oem get_unlock_data
2. Take the unlock code, edit it into a single string, and send it to Motorola using their website.
3. Take the unlock code and run: fastboot oem unlock [unlock code]
Now, I haven't even been able to run the first command as fastboot just hangs. I rebooted into fastboot mode and verified that the device was connected (the serial number appears when running "fastboot devices"), but when running "fastboot oem get_unlock_data", the program just hangs.
Here are the device details:
Stock ROM (obviously)
May 1st security patch
USB Debugging and OEM unlocking enabled (checked and double-checked)
PC details:
Arch Linux (kernel 5.1.15-arch1-1-ARCH), x86_64
Using latest Android Platform Tools, as of June 28, 2019.
android-udev package installed.
I've also attempted doing the same on a Windows 10 PC, but to no avail. Is anybody else facing this issue, or is there something important I'm missing? TIA
I have used motorola 3G two times and 2G once i tried to unlock bootloader i hot same issue what u have to do are follow the all steps correctly find out form of moto 3G and try to unlock ur phone again theres something wrong like u are not opening the cmd command in same folder where u installed the adb fastboot
I have a Lex620 MTK with stock android 6.0, EUI 6.0.030s was trying to unlock bootloader and install twrp by following this post
https://forum.xda-developers.com/le-2/development/bb72-how-to-install-bb72-custom-rom-t3497488
however after I am upto step 5
5.) Click on adb_cmd.exe command contained in LeTV-X620-RECOVERY-TWRP_GS_BB72 folder and type fastboot oem unlock
go into the fastboot mode as I was typing "fastboot oem unlock" the phone will go into the system in less than 20 seconds.
even I type very fast!
the CMD say waiting for device then the phone goes into android.
any solution for it?
thanks
Hello all!
I am attempting to re-lock my A30.
I have flashed the stock firmware and unlocked Developer mode and USB debugging
I've tried via adb in the following way (because flashing stock firmware alone did not re-lock)
enter command -> reboot bootloader
phone goes into download mode
enter command -> fastboot oem lock
Phone does nothing and adb Powershell window sits there with "waiting for device"
Any assistance would be magic, thanks so much
*** Please see link below for solution ***
