I can get the Samsung Galaxy J2 (Metro PCS) [SM-J260T1] to go into DOWNLOAD Mode with a
ADB Command: adb reboot bootloader
Did not see any dev options to unlock the bootloader for this phone.
Also because the buttons are vitrual on this phone's UI, the Button Method will not work.
Must be done at the low level software or ADB Mode.
Anyway to get the actual bootloader to unlock?

unlocking a bootloader is not a piece of cake. You will need to go through some programming codes and you will need to be cautious. Before we proceed further you must remember that doing this will void the warranty of your LG G pro 2 and you yourself will be responsible for any damage.
1. Download Android SDK and install it. It is easily available on internet from any source, install all Google USB drivers.
2. Enable USB debugging as shown in the steps while rooting your device.
3. Plug in the USB cable into your Smartphone and connect it with your PC.
4. Type adb devices > adb reboot bootloader > fastboot devices > fastboot oem unlock.
You have to insert all the commands shown above in the same sequence. Let me make you understand the meaning of these commands.
adb devices: This command will check and navigate whether your device is plugged in and revealed in SDK.
adb reboot bootloader: This command reboots your Smartphone into bootloader.
fastboot devices: This command double checks that your LG G pro 2 is connected.
fastboot oem unlock: This is the final command which will make your device to unlock bootloader.
After typing this command, on you Smartphone a confirmation screen will be shown. You just have to press Volume Up button for yes and Power off button to confirm.
Now you have to just restart your device and your bootloader will be unlocked. Kindly use these tricks with extra care and don’t worry all these tricks are safe and already experimented

Yes this is true for older phones but will NOT work for any variant of the l g pro 2 don't get excited guys....
So I'm wondering how come we can install and use PhilZ Touch recovery if the bootloader is locked. Or has PhilZ recovery image been signed or bumped or what?
I just learned about the power of ADB and USB Debug. I'm wondering if I put my galaxy device into download mode, can I do stuff like oem unlock using fastboot?
I have a stubborn galaxy j5 pro that refuses to give me oem unlock via dev options (and I've tried everything possible btw). Fastboot would be my last resource to unlock its bootloader.
If I can't do it to root it, then I think I can be happy just debloating with the beautiful ADB commands.
Yes, I have searched the whole forum and after finding mixed answers I decided to post a question myself. I have used the Huawei Bootloader Unlock app from the Play Store in a P10 Lite and it worked fine but it says P20 is not supported. I have read on methods like disassembling the device but that's out of my range. So the question here is: Is there ANY way (apart from the disassembling one) to unlock the bootloader?
Thanks.

I asked DC_Unlocker Support if they could Unlock my Bootloader on my P10Lite with android 8 ! And they told me after Android 8, and Emui 5+ the P10Lite Devices aren't Supported now.
If their would be a Way or if anyone has an other Idea... DLoad, Flashing Roms Rollback didn't worked for me.
But i would really like to try other Ways if their would be a Chance for a Working Way to Rollback on Android 7. Couse than DC-Unlocker would Work and could Unlock the Bootloader and Root the Phone, Flash TWRP and Doing much other things.

I'd love to know... I have my unlock code, but I have no idea how to use it. I got my code from Huawei before they stopped providing them.

First of all, enable the Developer Option
1. To Enable the Developer Option, Go to your Settings –> System -> About Phone -> Now Tap on the Build Number 7-8 Times until you see a toast message “Developer option enabled“
2. Now go to Developer optiosn in the settings and Enable OEM unlock
3. Download Minimal ADB and Fastboot
4. Turn off your phone and Press Volume Up and Power button simultaneously to open Fastboot mode or enter the command [to enter command, you need to connect your phone to PC using USB Cable]
Code:
adb reboot bootloader
5. now unlock your device’s bootloader with this command line.
Code:
fastboot oem unlock *****************
You need to replace the ****** with the unique unlock code.
Once it is done, you can reboot your phone. Now you can install TWRP Recovery, Custom Kernel, Root or even install Custom ROM. Enjoy!

Wow thanks! I'll get on that this weekend!
Hi there, I've been having trouble rooting my Samsung Galaxy A20 - SM-A205GN for awhile now. I'm officially on Android Version 10 with One UI Version 2.0, I've followed the provided guide to root my device but it fails on Odin "all versions" when I flash the recovery.tar file. After it fails it gives me a prompt on my phone on recovery mode saying Custom Binary (BOOT) Blocked By OEM Lock. I have enabled OEM Unlocking and USB debugging but it seems like it doesn't enable is there a way that your carrier can block these options to not enabled because that's what my starting to think why I can't seem to root my device. Can anyone suggest any workaround or fixes for this problem.
While your phone is turned off hold down both volume buttons and connect the usb cable, it will give you 2 options just hold down the volume up button and your bootloader will be unlocked

This happens to the a207f because it has Snapdragon instead of Exynos
You have to flash Stock Firmware
Boot back to download mode and long Press Volume up button.
then you will be oem unlocked
....except not that I unlocked and relocked bootloader on s10e it won't show up again in developer options
I've just got Realme GT2 PRO (RMX3300) (China ROM) and I need to flash the global ROM on it. but with all of my knowledge and hours and days wasted trying to flash the global ROM I am still unable to.
my main problem is that the phone doesn't have fastboot or bootloader !!!, I honestly never seen a phone that doesn't have a bootloader, and accessing it is necessary to flash a ROM or Unlocking the bootloader
here are some of the things i tried:
1- turning off the phone then holding the VOLUME DOWN and POWER BUTTON (AS SHOWN IN THE PICTURE) only puts me in recovery mode
2- using commands such adb reboot bootloader just restart the phone and shows a weird Chinese text for a split second (AS SHOWN IN THE VIDEO)
3- tried installing DEEP TESTING app but it gives me this error (AS SHOWN IN THE PICTURE)
I am honestly very desperate at this point and I am willing to pay anyone who manages to fix this issue
Tl;dr : can't go into bootloader/fastboot

Each computer so also every Android phone ( regardless of brand / model ) has a bootloader. Whether Google's Fastboot tool is supported or not on Android phone depends on brand / model: e.g. Samsung does NOT support it whereas Realme does.
