Unlocking the device's bootloader is often the first step before rooting. This article explores the many methods now available to Unlock Bootloader Samsung devices.

For most, Android devices are easy for programmers to work with, which is why specialized software designers choose the Android platform. While there is a plethora of third-party Android software like firmware, mod documents, etc., Android enthusiasts and fans demand great control over their phones. Unlocking the bootloader initiates the customizing phase. Learn more below.

Part 1. What is Bootloader Unlock on Samsung Devices?

The Samsung Galaxy Bootloader is the first line of code executed by the device before the user can access the system settings or install an operating system. Before the boot logo appeared, the bootloader instructed the hardware to begin the boot process, which can involve loading an operating system or entering a recovery mode.

For privacy and security reasons, all Android devices' bootloaders are locked by default. The bootloader on the vast majority of Android phones is not user-accessible. This feature disables the ability of the user to access the device's root directory. When the bootloader is secured, the user cannot install custom firmware or operating system images. It's an extra layer of protection for your Android phone.

The Bootloader software begins executing when you power on or restart an Android device. In addition, it provides the Operating System with the appropriate instructions to ensure the devices function as intended. The mobile operating system market, however, is crowded with several vendors. Each maker has its inimitable bootloader and distinct set of lines of code.

Part 2. When Should You Unlock Your Samsung Bootloader?

Your Android device's full potential can't be accessed until the bootloader is unlocked, so that's the first thing you need to do. A bootloader is a lightweight piece of software that loads the operating system into the memory of your device.

Pros of Unlocking Samsung Bootloader

  • Flash your custom ROMs.
  • Get access to Custom Recovery.
  • Install root access.
  • Some original equipment manufacturers (OEMs) already provide a technique or tool for bootloader unlocking.

Cons of Unlocking Samsung Bootloader

  • The warranty on your device is at risk of being voided.
  • It is possible that the performance of the gadget will not be identical to what you expect.
  • If you unlock the bootloader incorrectly, you risk bricking your device or being stuck in the boot state.
  • There is a possibility that the privacy or security protections of the handset will be compromised.
  • Unlocking the bootloader will result in the total deletion of all data stored on the device.

Pre-Requisites for Unlocking Samsung Bootloader

  • After that, install the ADB and Fastboot Tools for Windows on your computer by downloading them first.
  • Get a laptop or PC by your side. A USB cable is also a must!
  • In addition, you need to take a full backup of your device that does not include Root.
  • Be sure your gadget has a charge of at least 60 percent.
  • Back up all of your important content on the device. For this, we recommend using Fone - Phone Backup (Android).

Method 2. How to Unlock Bootloader on Samsung Using Samsung Bootloader Unlock Tool?

Before moving on, it is important to remember that unlocking the bootloader will permanently activate Knox. You can't utilize services such as Samsung Pay or Secure Folder in the future.

The situation is made much worse because any data you can have stored in the Secure Folder will be lost forever. Because re-locking the bootloader is a one-time operation, undoing the modification will not be possible. You can learn more about it by reading this article.

Let's not waste any more time and get down to business now that that's out of the way.

Step 1: Ensure your Samsung phone's Developer Options are turned on. Both Android 9 and Android 10 follow a method that is, for the most part, identical.

Step 2: To allow original equipment manufacturer unlocking, go to Settings > Developer Options, scroll down a little until you locate a toggle that reads "enable OEM unlocking," and then turn it on.

Step 3: You must download ADB and Fastboot and set them up on your computer. After the file has been downloaded, go to the directory where it was saved and start a command prompt or terminal with administrative rights.

Step 4: Entering the following command into your computer will ensure that the machine recognizes the phone:

adb devices

Step 5: After you have received confirmation that your device has been found, enter the following command into the console:

adb reboot bootloader

Step 6: After that, the bootloader should load on your phone when it reboots next. If it doesn't automatically do so, you can manually boot your phone into the bootloader by turning off the device, then turning it back on while simultaneously pressing and holding the Power and Volume Up rockers. This will cause the phone to boot into the bootloader.

Step 7: Enter the following command on your phone's keyboard after it has entered the bootloader mode:

fastboot flashing unlock

Step 8: You can traverse the menus using the volume button and acknowledge the on-screen question by pressing the power button.

Important Warning: This step will erase all of the data that is currently stored on your phone. After the procedure is finished, you can begin typing again.

Step 9: Your phone needs to now restart into Android with the bootloader unlocked for it to work properly.
