Step 1. Go into Settings->About Phone and tap on the “Build number” about 5 times.
You should see a message similar to, “You are now a developer” or “Developer mode has been turned ON”.
Step 2. Tap on back button once(or twice) and you should see a new menu option called, “Developer options”, tap on that.
Step 3. In “Developer Options” menu, make sure “OEM Unlocking” is checked ON. Now, some of the older Android devices may not have this option. If you don’t see the option anywhere, you can skip this step.
Step 4. Download fastboot.zip and ADB Drivers(for Windows, no drivers needed for Mac or Linux).
Download fastboot.zip & ADB Drivers (https://highonandroid.com/fastboot-zip-android-usb-drivers/)
Once fastboot.zip has been downloaded, unzip/extract all files to “fastboot” folder in your “Downloads” directory.
Step 5. If using Windows, run the ADB Driver program you just downloaded. This will work for all Windows XP, Vista, 7, 8, and 10. For Mac or Linux, you can skip this step.
You can verify that your drivers are working correctly by going into your Windows Device Manager and you should see something like, “Android ADB Interface”. In my case, it says, “Google Nexus ADB Interface”. If you don’t see it after installing drivers, try unplugging the USB cable from your Android device and plugging it back in.
Step 6. Go to your Android device immediately and a pop-up window should appear, make sure to tap on “OK” if you see “Allow USB debugging”. This is so you can use ADB commands to your Android device which we will be doing.
Step 7. For Windows, open a command prompt by typing “cmd” in the Windows search bar. For Mac or Linux, open a terminal. If you don’t know how to do this, you can Google it.
Next type the following.
For Windows:
cd Downloads
cd fastboot
adb reboot bootloader
Note: “Downloads” folder is the default download folder for most computers. If yours is different, type that instead here.
For Mac:
cd Downloads
cd fastboot
chmod 755 *
./adb-mac reboot bootloader
Note: The “chmod” command is required to change file permissions on both Mac or Linux before you can execute them.
For Linux:
cd Downloads
cd fastboot
chmod 755 *
sudo ./adb-linux reboot bootloader
Note: The “sudo” is required if you are running your Linux system as a user. You can also simply type, “sudo -i” to enter root mode then you don’t have to type sudo in front.
Step 8. Next we will unlock the bootloader with the command, “fastboot oem unlock” OR “fastboot flashing unlock”. It doesn’t hurt to try either but one of them will unlock the bootloader. This is due to the newer fastboot commands on newer phones.
So type the following.
For Windows:
or
fastboot oem unlock
or
fastboot flashing unlock
For Mac:
or
./fastboot-mac oem unlock
or
./fastboot-mac flashing unlock
For Linux:
or
sudo ./fastboot-linux oem unlock
or
sudo ./fastboot-linux flashing unlock

Your Android device should reboot but if it doesn’t use the bootloader menus and select, “Start” to reboot your Android.
Step 9. Wait for about 5-10 minutes for your Android device to boot fully.
Step 10. You should see a welcome screen just like the first day you got your Android device. Congratulations, you have successfully unlocked the bootloader, ready to root your Android!
