How to Unlock Bootloader on an Android Device – Guide
You can now unlock your PC-less bootloader using adb and fastboot. This guide can help you fix bootloader unlocking allowed no errors. Additionally, some OEMs like Xiaomi, Sony, HTC, Samsung follow a different path when it comes to completing this process. So to consider this, there is a separate section for it in the final of this guide.
The main concern or question that turns on the mind is whether or not a Bootloader is necessary to unlock a device. Well, in short, if you’re not one of those technical geeks who likes to tweak your devices’ software, then we suggest that you don’t unlock the device’s bootloader. While there are many benefits to having an unlocked bootloader, it also has its drawbacks. Let’s take a look at both sides of the coin here.
Step Zero: Back Up whatever you want to keep
Before starting, it is important to mention that 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.
When did you support up whatever you want to keep, continue with the steps below.
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.
- Start by opening the Start screen and typing “cmd” into the search bar.
- Type “netstat -an” to view active network connections.
- Type “ping -n” to test whether your computer is connected to the internet.
- Type “wireshark -l” to view all network traffic in detail.

If your device has been recognized and you can continue with the process, it is likely that you have followed all of the steps correctly. If not, please follow these steps to correct the issue:
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. ..
Developer Options on the Settings page:
- Activate “OEM Unlock” if it doesn’t exist.
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 enabled USB debugging on your phone, connect your phone to your computer. You should see a pop-up titled “Allow USB debugging?” On your phone. Check the “Always allow from this computer” box and tap OK. ..
Step three: get an unlock key (for non-Nexus Phones)
If you are using a Nexus device, you can skip the next step and continue with the instructions below. If you are using a non-Nexus device, you will need to go through an extra step before continuing.
Once you have logged in or created an account, you will be able to unlock your device’s bootloader.
First, turn off your phone and boot into fastboot mode. This is a little different in each phone, but on most modern devices, you can get there by holding the “On” and “Volume Down” keys for 10 seconds. Drop them and you should be in fastboot mode. Usually, you can find more information about yours on the manufacturer’s website.
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.)
To get started with Android development, open the platform tools folder in your Android SDK folder and type “adb devices” into the command prompt. This will list all of the devices connected to your computer. ..
fastboot oem unlock
To factory reset your Nexus 5X or 6P:
- From the Home screen, tap the Settings icon.
- Under “General,” tap “Reset.”
- Tap “Reset phone.”
- Tap “Erase everything.” ..
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 prompt you to unlock it. Use the volume keys to confirm. ..
When finished, use the on-screen menu to reset your phone (or run the fastboot reboot command on your PC). If everything worked correctly, you should see a new message on startup that your bootloader is unlocked and after a few seconds it should boot into Android. It’s important that you boot Android before doing anything else, such as updating a custom recovery.
