Unlock Android Bootloader Via Fastboot

Of all the big advantages that the Android ecosystem has to offer, its open-source aspect is without a doubt at the top. Users are usually spoilt for choice after opening the doors to a plethora of customization options. A simple visit to the Play Store will be sufficient for the majority of users’ needs. They could add custom launchers, themes, icon packs, wallpapers, and ringtones, for example. They might also sideload their favorite applications onto their computers if that wasn’t enough. All of this, though, is just the tip of the iceberg.

The true potential of a computer is normally unlocked by tech enthusiasts who go one step further. They could install a new custom ROM that is completely different from the stock OS on their computer. Then there’s the option to swap out the stock recovery for a custom recovery like TWRP, which allows you to install a variety of plugins, frameworks, ZIP, IMG, and other tweaks. If you want to take it a step further, rooting your computer will grant you administrative rights and allow you to make changes to the system partition.

These are only a few of the customization options available; there are a plethora of other options available. However, there is a significant condition that must be met for each of the above modifications. And that means your device’s bootloader should be unlocked. So, if you’re ready to give these tweaks a shot, here’s how to unlock the bootloader on any Android device using the fastboot process. Follow along with me.

What is a Bootloader?

The first question that might come to mind is what exactly is an Android bootloader. “A bootloader is a vendor-proprietary picture responsible for pulling up the kernel on a device,” according to Google. This is much too much to take in. In simpler terms, a bootloader is a software program that decides which programs should be loaded when your computer starts up.

It also makes it easier for the system to enter bootloader mode. Similarly, every Android device has a few partitions, including boot, recovery, machine, info, and vendors. The Bootloader is a protection mechanism for these partitions, ensuring that their dignity is preserved and that no changes are made to them.

What is an Unlocked Bootloader?

The bootloader acts as a protector for all system partitions, ensuring that no changes are made to any of them. It must ensure that you are running the original software program that came with the unit. But here’s the thing: there’s a catch. This default operating system does not appeal to everyone. There may be several reasons for this. For example, they might dislike the user interface, be opposed to in-app advertising, or be annoyed by the numerous bloatware apps that come pre-installed.

The explanations may be numerous, but there is only one solution: unlocking the bootloader on your Android computer. As soon as you do so, the system can remove any limitations on the level of customization you can achieve. You could get a bootloader unlocking alert message at boot time, but that’s it. There will be no restrictions on taking advantage of the advantages that an unlocked bootloader provides. But, first and foremost, what are these advantages? Let’s take a look.

Advantages of an Unlocked Bootloader

If your Android device’s bootloader is unlocked, you can install a custom recovery like TWRP. This will allow you to install mods, wipe various system partitions, backup Nandroid, and install files via ADB, among other things. You can also install several common custom ROMs such as LineageOS, HavocOS, and Pixel Experience if the system bootloader is enabled. Not only will this offer your smartphone a new look, but it can also update the device’s Android edition, even if the upgrade is no longer officially planned.

Similarly, Magisk allows you to gain quick access to system-level files and make changes as required. Rooting the unit is a more straightforward term for this. We might go on and on about the advantages, but there’s another side of it as well. The process of unlocking the bootloader on an Android device comes with a number of risks. So, before you begin the measures, make sure to review the risk factor mentioned below.

Risks with Unlocked Bootloader

Unlocking the bootloader comes with a number of drawbacks. For starters, your computer is now more vulnerable to attacks. Additionally, your OEM can render the device’s warranty void and null. Similarly, some banking applications, such as Google Pay, and games, such as Pokemon GO, do not work properly. Similarly, you will be downgrading your Widevine Certification from L1 to L3, which will prevent you from watching Netflix in HD. The process is risky in and of itself, and if performed incorrectly, it may brick your computer or cause it to bootloop.

But now you’re aware of all the benefits and drawbacks. If you’re ready to go, follow the steps below to use the fastboot method to unlock the bootloader on any Android device.

How to Unlock Android Bootloader Via Fastboot Method

Before we start opening the bootloader, let’s take a closer look at what a bootloader is and what benefits or drawbacks you’ll get once it’s unlocked. We’ve broken down the unlocking process into basic steps to make it easier to understand. Follow along with me.

Warning: Before we start unlocking the bootloader, I highly advise you to make a backup of your device’s storage and all of the files stored on it. The data on your computer will be erased if the bootloader is unlocked. Furthermore, to prevent permanent damage or bricking of your system, it is recommended that you carefully follow the steps outlined in this article. If something goes wrong, neither the author nor GetDroidTips are liable.

1. Backup your Device:

To begin, make a full backup of your Android device. This is due to the fact that the procedure would delete all of the data on your computer. You may consult our in-depth guide on the topic.

2. Enable USB Debugging and OEM Unlocking:

After that, you’ll need to allow OEM unlocking and USB Debugging. The former is needed to start the procedure. The latter will aid in the effective establishment of an ADB link between your system and your computer. The choice to allow both of them can be found inside Developer Option, which is itself secret. Here’s how to make them both work.

Enable USB Debugging and OEM Unlocking

  • On your Android smartphone, go to Settings.
  • Go to Settings > About Phone > Build Number and tap it seven times.
  • Return to Settings and choose System, then Advanced.
  • Now you should be able to see the Developer Options. Toggle the toggles next to USB Debugging and OEM Unlocking to on.

3. Install Android SDK Platform Tools:

On your PC, you’ll also need to install the ADB and Fastboot binaries. This is required for ADB and Fastboot commands to be executed between your PC and your Android device. So go ahead and add the Android SDK Platform Tools to your device.

4. OEM Specific Prerequisites:

While the unlocking process on Pixel Nexus and Android One devices is fairly simple, some OEMs, such as HTC, Nokia, Motorola, and HTC, among others, require an unlock token, special codes, or even a specific file. Before you begin the fastboot method of unlocking, you must first complete these criteria. You may use the links below to get support, then follow the instructions and move on to the next level.

Device-Specific Requirements: Motorola | HTC | Sony | Nokia

5. Boot Device to Fastboot/Bootloader Mode

  • You must now boot into Fastboot/Bootloader mode on your computer. To do so, follow the steps below:
  • Connect your computer to your PC using a USB cable if USB Debugging and OEM Unlocking are allowed.
  • Go to the platform-tools folder, type CMD, and then press Enter. The Command Prompt will open as a result of this.
  • To ensure that the system has been successfully connected to the ADB mode, run the following command in the CMD window:

Boot Device to Fastboot

  • Your computer will prompt you to Authorize USB Debugging as soon as you do so. Select OK. If you’re performing these steps on your own computer, you can also select the Always enable from this computer choice.

  • To boot your computer into Fastboot or Bootloader Mode, type the following command:
  • Now follow the steps below to finally unlock the bootloader on your Android device using the fastboot process.

6. Unlock Bootloader

  • Now comes the most crucial part. If you have a Google Nexus, Pixel, or any other OEM system released in 2015 or later, use the fastboot command below to activate the bootloader. Keep in mind that the command below will delete all info.
  • If your computer was released before 2015, however, the following command would be useful:
    OEM unlock fastboot
  • A confirmation message should appear on your computer at this stage. Pick Unlock the Bootloader with the Volume keys, then confirm your choice with the Power button.
  • The procedure can now only take a few seconds. The computer will then boot to the bootloader or framework. If it boots to the operating system, that’s great; if not, use the code below.

Unlock Bootloader

  • That is everything there is to it. These were the steps needed to use the fastboot method to unlock the bootloader on your Android device.


It’s important to remember that the first boot will take some time; this is perfectly natural. Another point worth noting is that your system can still use the older fastboot OEM unlock command even if it was released after 2015. If the fastboot flashing unlock command fails in your case, you should try the first option.

You’ll also see the Unlocked Bootloader alert message after each boot, which is nothing to be concerned about. Since your laptop has been cleaned, you will need to sign in with your Google account when it boots up. On that note, please let us know if you have any questions in the comments section below.
