Want to unlock the bootloader of your Samsung Galaxy for advanced tasks like flashing custom ROMs, rooting your phone, executing fastboot commands, and other tasks? Here is a detailed guide to unlock the bootloader of your Samsung phone.
While unlocking the bootloader offers various benefits, it also comes with some restrictions and disadvantages, such as voiding the warranty, resetting the phone, and exposing it to security risks. So, it’s important to be aware of such details before unlocking the bootloader of your Samsung phone.
Samsung has a large number of devices in its library, but not all devices are eligible for bootloader unlocking. In some regions and carrier-locked devices, bootloader unlocking is restricted. Therefore, this method will only work if unlocking the bootloader is allowed on your device. You can check your device’s eligibility by attempting the unlocking process.
Enable OEM Unlocking on your Galaxy
To unlock the bootloader of your Samsung phone, you must first enable OEM unlocking. This option is hidden under Developer options. Here’s how to enable it.
- Open Settings on your phone and go to About Phone > Software Information.
- Look for the Build Number and tap on it seven times. It will ask for your device password, and the developer options will be enabled.
- Go back to Settings and you will find Developer options at the last, open it.
- Scroll down a bit and enable OEM unlocking. Also, enable USB debugging, which will be required for adb fastboot commands.
If the OEM Unlocking option is disabled and grayed out, make sure to log in with your Samsung account on your phone and wait for at least a week before attempting it again. If the issue remains, your device will not be eligible for a bootloader unlock.
As mentioned earlier, unlocking the bootloader will erase all data on the device. Make sure to back up your device before proceeding with further steps.
