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).
Follow the steps below to make a backup of your contents using Dr.Fone - Phone Backup (Android):
Step 1: To begin, have Dr.Fone installed on your computer and connect your Android phone or tablet to it. The next step is to access "Backup & Restore" from the app's main menu.
Step 2: If a prompt on your Android device asks you to enable USB debugging, just hit "OK." Then, choose "Backup" to begin saving your data.
Step 3: When you choose "Backup" up top, Dr.Fone will display a menu detailing the many information and files that can be backed up.
Step 4: Click "View Backup History" after the complete Android backup to verify that you have a copy of all the data you need.
Part 3. Steps to Unlock Bootloader on Samsung Devices
Now that you have been made aware of what unlocking the bootloader on samsung means, its advantages, drawbacks, and what sort of pre-requisites you can get before doing it, it's time to get started with the main process. Here are the two ideal methods for any beginner to begin with.
Method 1. How to Unlock Bootloader on Samsung Through Enable OEM Unlocking?
The first method on our list involves unlocking Samsung bootloader by enabling OEM Unlocking:
Step 1: First things first, check to see that your gadget has enough amount of energy and that it is linked to a Wi-Fi network.
Step 2: Now go to Settings > Software update > System updates > After that, tap on the option to either Check for system updates or Download and install the update (If you find an update available, install it first).
Step 3: After that, you will need to activate the developer option on your Samsung smartphone.
If you follow the instructions indicated below, you will be able to activate the developer settings:
- Stage 1: Navigate to the Settings menu on your Samsung mobile device.
- Stage 2: Select the About phone option on your Samsung devices.
- Stage 3: Now go to Software information, and after that, tap seven times on the option that says Build number.
- Stage 4: After that, navigate back to the main settings page.
- Stage 5: After that, go to the settings menu of your Samsung device and look for the option labeled Developer.
- Stage 6: Launch the Developer Option at this time.
- Stage 7: After that, activate the OEM Unlocking toggle button and, if prompted, permit to do so.
Step 4: Now totally power down your Samsung smartphone, then press and hold the Volume Up and Down keys simultaneously on your Samsung device, and then connect your Samsung device to your personal computer using a USB connection.
Note: Performing this action will put the Samsung device you are using into Download/Recovery Mode.
Step 5: Press the Volume Up key on the phone until the "Unlock Bootloader" screen displays. This should be done as soon as you reach the Download or Recovery menu.
Step 6: Then, on the next page, hold the Volume Up button once again to unlock the bootloader [If you are prompted that unlocking the bootloader would wipe all of the data that is currently stored on your device, continue].
Step 7: The next step is to wait until the procedure is finished when your device restarts.
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:
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.

Step 1: Go to Dr.Fone's main page and choose "Screen Unlock" from the menu.
Note: A working internet connection is required to use an Android smartphone. To remove the FRP lock from your device, go to the following screen and choose the "Unlock Android Scree/FRP" option from the menu.
Step 2: To begin unlocking your Samsung from the confines of your Google account, tap the "Remove Google FRP Lock" option.
Step 3: In the new window, choose "Android 11/12" from the list of supported platforms. Launch the program by clicking "Start" and then connect your Samsung device to the computer through the USB cord.

Step 13: The new menu appears as soon as you find the choice and press on it. Choose "Open," then on the next screen, mark "MTP + ADB" and hit "OK."
Note: A new alert window is shown on the screen, prompting you to allow USB Debugging. Once activated, your Samsung has to be disconnected from the PC. You can proceed once you plug the gadget back in.
Step 14: During this time, you will need to restart your device. While your Samsung is restarting, go to "Settings." Then, go to the "General Management" menu and choose "Reset." Then, choose "Factory data reset" from the menu.
Step 15: Verify that your Samsung device is resetting correctly. This finishes a successful bypass of Google Play Protect for Samsung devices.
Now that your Samsung phone's bootloader is unlocked, you can root it and install a custom operating system and recovery image.
