There are many benefits to having an unlocked bootloader on your Android device.

However, there are also drawbacks to having an unlocked bootloader. One drawback is that if your device is stolen or lost, someone else can easily access your data and settings without needing your password or PIN. Another drawback is that if you experience a software issue and need to factory reset your device, you will lose all of your data and settings. ..
Step Zero: Back Up whatever you want to keep
Before starting, it is important to mention: this process will erase all your data. So if you have photos or other files on your phone you want to keep, download them to your computer now. Also, if you have any application settings you want to keep, use the backup function to create a backup settings file and transfer them to your computer as well.
Since I know that eventually I will root my phone, I always unlock my bootloader as soon as I buy a new device. So I don’t waste time configuring up just to erase the phone in a few days and do it all over again. If you’re an obsessive Android tweaker who knows you’ll be rooting for it soon, consider unlocking before going through the setup work up your phone.

Step one: Install the Android SDK and your PhoneDrivers from
To use the Android Debug Bridge, you will need to install the Android SDK and the Android Debug Bridge. The Android SDK is a set of tools that allow you to build applications for the Android platform. The Android Debug Bridge is a program that allows you to connect your computer to your phone and access its resources. even if you’ve installed this before, you should get the latest versions now.
To install Kodi, first you’ll need to download the appropriate software. Once you have the software downloaded, open it and click on the “Install” button. Next, select “Kodi” from the list of programs and click on the “Install” button. Finally, enter your user name and password when prompted, and click on the “Finish” button.

If your device has a serial number, you can continue with the process. If not, make sure you have followed the instructions correctly. ..
Step Two: Enable USB Debugging
To enable some options on your phone, open the phone application drawer, tap the Settings icon, and select “About Phone”. Scroll all the way down and tap the “Build Number” item seven times. You should get a message saying you are now a developer. ..
On the main Settings page, you will now find a new option called “Developer Options”. If it exists, activate “OEM Unlock”. ..
When you enable USB Debugging, your device will start to show debugging information on the screen. This includes information about how you are using your device, such as the type of device you are using and the version number. You can also see what apps are running on your device and how they are connecting to the internet.
Once you have connected your phone to your computer, you will see a pop-up asking if you want to allow USB debugging. Check the box and tap OK.
Step three: get an unlock key (for non-Nexus Phones)
If you are using a Nexus device, you can bypass the next step. Non-Nexus devices will likely need to go through an extra step before they can continue. ..
To unlock your device’s bootloader, go to the manufacturer’s website and sign in or create an account. ..
To begin, turn off your phone and boot into fastboot mode. This is a little different on each phone, but on most modern devices you can do this by holding the “On” and “Volume Down” buttons for 10 seconds. After 10 seconds, release the buttons and you should be in fastboot mode. (HTC users will need to select “Fastboot” with the Volume Down key and press the power button to select it first.) Usually, you can find more information about your phone by doing a quick Google search. If you want to continue without doing that, feel free to do so now. ..
Connect your phone to your computer with a USB cable. Your phone should indicate that the device is connected. On your computer, open the platform tools folder in your Android SDK folder and type “fastboot oem get_unlock_data” into the Command Prompt window. (For Motorola phones, this will run the fastboot oem get_unlock_data command; for HTC phones, it will run the fastboot oem get_identifier_token command.) ..
The Command Prompt will issue a token in the form of a long string of characters. Select, copy and paste into the applicable box on the manufacturer’s website – make sure there are no spaces! – and submit the form. If your device can be unlocked, you will receive an email with a key or file that you will use in the next step.
If your device cannot be unlocked, you will receive a message informing you of this. If you want to root your device or flash a ROM, you will need to use an unofficial method, which can usually be found on a website like XDA Developers.
Step four: unlock your Phone
If your phone is still in fastboot mode, run the command below. If not, turn off your phone and hold the “Power” and “Volume Down” button buttons for 10 seconds. Drop them and you should be in fastboot mode. (HTC users will need to select “Fastboot” with the Volume Down key and press the power button to select it first.)
Open a command prompt here and type: com.android.sdk.platformtools
fastboot oem unlock
If you have a Nexus 5X or 6P, the command will be a little different: To change the language of your Nexus device, use the following command: Nexus Language
If you have a non-Nexus device, the manufacturer will tell you how to unlock it. Motorola devices, for example, need to run fastboot oem unlock UNIQUE_KEY, using the unique key from the email you received. HTC devices will run fastboot oem unlocktoken Unlock_code.bin using the Unlock_code.bin file you received from HTC. ..
After executing the command, your phone may ask if you are sure you want to unlock. Use the volume keys to confirm.
If everything went according to plan, you should now see a message on your phone’s screen indicating that your bootloader has been unlocked and that you can now boot into Android. It’s important to boot Android before doing anything else, such as updating a custom recovery. ..
