All about Samsung Bootloader Unlock Tool


    There’s no arguing the fact that Android is a relatively flexible mobile OS. Users can customize everything they want and even install custom ROMs to get a personalized user experience. However, manufacturers like Samsung (and others as well) don’t want users installing a random OS on their devices. That’s why they usually ship their devices with a locked bootloader. When the bootloader is locked, the user cannot install a custom OS whatsoever.

    The good news is that there are a few walkarounds that you can implement to unlock the bootloader on your Samsung device. Read this guide to understand how to use a Samsung bootloader unlock tool to unlock the bootloader on your Samsung device.

    What Is Samsung Bootloader?

    Now, if you are not a technical geek, you may not be familiar with the bootloader in a Samsung device. To put it in simple words, a bootloader is basically software that automatically loads as soon as you turn on your device. Every Android device (irrespective of the manufacturer) comes pre-installed with the bootloader. The primary objective of the bootloader is to load all the essential programs that are necessary to start the device. So, for instance, if you want to boot your device in recovery mode, the device will only load the selected programs required for the job.

    So, why would you want to unlock the bootloader? The answer is pretty simple. A locked bootloader will restrict you from adding a custom OS to your device. So, if you are not happy with the current OS and want to install a custom ROM, you’ll first have to unlock the bootloader.

    Moreover, many people also wonder if it’s safe to unlock the bootloader. The truth is unlocking the bootloader doesn’t raise any safety issues. As long as you install a reliable third-party ROM, it won’t affect your device whatsoever. The only downside of unlocking the bootloader is that it’ll end your device’s warranty.

    When You Need A Samsung Bootloader Unlock Tool

    It’s worth noting that there’s no direct way to unlock the bootloader. Since it’s a security feature, none of the manufacturers provide a dedicated button to lock/unlock the bootloader. In every situation, you’ll need a dedicated Samsung bootloader unlock tool to get the job done.

Even if you’re a beginner, you’ll find it pretty convenient to unlock the bootloader using KingoRoot.

    Follow these steps to unlock the Samsung bootloader using KingoRoot.

    After you’ve unlocked the bootloader, you’ll be tempted to install various custom ROMs and access new features on your device. While this is a great tactic to explore the hidden functionalities of Android, it’s also worth noting that it can make you run into various technical errors. A locked FRP screen is one such error that many users come across while switching between different custom ROMs.

    FRP stands for factory reset protection. It’s a security feature that automatically locks the device after you reset it. The only way to unlock the device is to use your Google account credentials. But, in case you don’t remember the Google account or password, you can use iToolab UnlockGo (Android) to bypass the FRP lock.
