What is a bootloader?

A bootloader is a specialized operating system software that runs on a device when it is powered on. Its primary function is to initialize the hardware and load the main operating system. Think of it as the gatekeeper that ensures the right OS is loaded securely.

Bootloaders are essential for starting up electronic devices, ranging from computers to smartphones, and even IoT devices. They operate at a low level, often before any user-facing software is running.

  • Initialization: Prepares the device’s hardware for use.
  • Verification: Checks for the integrity and authenticity of the OS.
  • Execution: Loads and hands over control to the device’s main operating system.

Bootloaders are crucial for system stability and security, as they lay the groundwork for a safe and functional device environment.

Why should you unlock bootloader?

Unlock bootloader on your device easily but it can be a gateway to a host of customizations and software updates that are not available through official channels. It allows you to install custom ROMs, recoveries, and gain root access, which can significantly enhance the functionality and performance of your device.

  • Custom ROMs: Install software that offers new features and improvements over the stock operating system.
  • Root Access: Gain full control over your device, allowing for advanced tweaks and potential performance boosts.
  • Latest Updates: Stay up-to-date with the latest Android versions, even if your device manufacturer no longer supports your device.

To unlock bootloader, you’re not just freeing your device from the constraints of the manufacturer’s software; you’re also opening up a new realm of possibilities for personalizing and optimizing your device’s performance.

However, it’s important to proceed with caution. Unlock bootloader can void your warranty and may expose your device to security risks. Always ensure you understand the risks and steps involved before proceeding.

Preparing to Unlock Bootloader

Back up your data

Before proceeding to unlock bootloader, it is crucial to back up all personal data on your device. This ensures that you can restore your information in case the process results in data loss. There are several methods to back up your data, including:

  • Using the built-in backup feature of your device’s operating system.
  • Syncing data with a cloud service provider.
  • Manually copying files to a secure external storage.

Remember, the backup process will vary depending on your device and operating system. Always verify that your backup is complete and accessible before moving forward to unlock bootloader.

Enable OEM unlocking

Before attempting to unlock bootloader, it is crucial to enable OEM unlocking in your device’s settings. This option is often hidden within the ‘Developer options’ menu, which can be accessed by tapping the build number in the ‘About phone’ section multiple times. Once ‘Developer options’ is unlocked, toggle the ‘OEM unlocking’ switch to unlock bootloader.

  • Go to ‘Settings’ and select ‘About phone’.
  • Tap ‘Build number’ seven times to unlock ‘Developer options’.
  • Return to ‘Settings’, choose ‘System’, then ‘Advanced’, and select ‘Developer options’.
  • Scroll down and toggle on ‘OEM unlocking’.

Ensuring that OEM unlocking is enabled is a vital step that must be completed before any unlocking process can begin. It serves as a form of consent, signaling that the user understands the risks and authorizes the modification of the device’s firmware.

Unlocking the Bootloader

Obtain unlock code

Before you can proceed to unlock bootloader, you must obtain an unlock code specific to your device. This code is essential as it ensures that only authorized users can perform the unlocking process.

To get your unlock code, you typically need to:

  • Visit the manufacturer’s official website.
  • Register for a developer account if required.
  • Provide your device’s unique IMEI or serial number.
  • Agree to any terms and conditions that apply to the unlocking process.

Remember, the process to obtain an unlock code can vary significantly between different manufacturers and even between models from the same manufacturer. It’s crucial to follow the specific instructions provided for your device to avoid any potential issues.

Use manufacturer tools to unlock

Once you have your unlock code, it’s time to proceed with the actual unlocking process. Each manufacturer provides a specific set of tools or commands to unlock bootloader. For instance, Android devices often require the use of the ‘fastboot’ command on a connected computer.

Ensure your device is in ‘fastboot’ mode and connected to your computer via USB before proceeding.

Here’s a general outline of steps you might follow, though the exact process can vary:

  • Install the necessary drivers and tools on your computer.
  • Open a command prompt or terminal window.
  • Enter the ‘fastboot’ command along with your unlock code.
  • Follow any on-screen instructions to complete the process.

After you have done unlock bootloader, your device may reboot automatically. It’s crucial to follow the manufacturer’s instructions carefully to avoid any potential issues.

Post-Unlocking Considerations

Re-locking the bootloader

You have successfully unlocked bootloader now you might wonder if you can reverse the process. Re-locking the bootloader is indeed possible and is a critical step if you’re concerned about security or if you need to send your device in for warranty service. However, it’s important to note that re-locking the bootloader will typically erase all data on the device, just as unlocking it did.

Before proceeding with re-locking, ensure that you:

  • Have backed up all necessary data.
  • Are re-locking for a legitimate reason, such as security or warranty purposes.
  • Understand that some devices may still show a flag indicating the bootloader was previously unlocked.

Re-locking the bootloader restores the device to its original state of security, but it may not reset the device’s warranty status if the manufacturer records the initial unlocking.

The process for re-locking the bootloader varies by manufacturer, but generally involves using the same tools you used to unlock it. Always follow the manufacturer’s instructions carefully to avoid bricking your device.

Security implications

Unlock bootloader can significantly impact the security of your device. Once unlocked, your device becomes more susceptible to malicious software and attacks. This vulnerability arises because the security layers enforced by a locked bootloader are no longer present.

  • Data integrity: An unlocked bootloader allows the installation of custom ROMs, which could potentially contain malicious code.
  • System security: With an unlocked bootloader, the device’s root access can be obtained more easily, posing a risk to system security.
  • Warranty and support: Many manufacturers void the warranty of a device with an unlocked bootloader, and official support may be withdrawn.

It is crucial to weigh the benefits of unlocking against these security risks. If you decide to proceed, ensure you download software from reputable sources and consider re-locking the bootloader after making necessary changes to maintain a higher security level.


In conclusion, unlock bootloader can be a useful process for advanced users who want to customize their devices. However, it comes with risks, and it’s important to follow the right tips and techniques to ensure the safety of your device. By following the guidelines provided in this article, you can safely unlock bootloader and enjoy the benefits of customization while minimizing the potential risks. Remember to always proceed with caution and make informed decisions when it comes to modifying your device’s bootloader.
