Once the bootloader is unlocked, the phone can be prepared for advanced modifications such as installing a custom recovery, gaining root access, or experimenting with a custom ROM. For the Realme 3, the unlocking process involves preparing the required Windows drivers and tools, connecting the phone, entering the required hardware mode, and then confirming that the bootloader has been successfully unlocked.
This guide walks through the process in a simple and organized way.
Important: Bootloader unlocking may erase the phone and can affect device security or software support. Back up your personal data before beginning. Use the procedure only on a device you own or are authorized to modify.
Before You Begin
The Realme 3 used for this procedure is running Android 10. The demonstrated setup uses firmware/build C.22.Prepare the following:
- Realme 3
- Windows PC or laptop
- Good-quality USB cable
- MTK/MediaTek USB driver
- USBDK component
- Bootloader unlock tool used for the procedure
- Stable USB connection
- Backup of important personal data
Why Unlock the Realme 3 Bootloader?
The main reason to unlock the bootloader is to open the door to further modification.For example, an unlocked device can be used as a starting point for:
- Installing TWRP or another custom recovery
- Rooting the phone
- Installing custom ROMs
- Performing other system-level modifications
Step 1: Check Your Realme 3 Software
Open the phone's Settings and check the Android version.The device used in the procedure is running Android 10. The tutorial also refers to build C.22 as the software version used for the process.
Your exact build may differ, so make sure the files and procedure you use are compatible with your particular Realme 3 variant.
Step 2: Prepare the Windows PC
Move the required files to an accessible folder on your PC.The setup includes an MTK driver and a USBDK component. Extract the driver package and install it before attempting to communicate with the phone in the required hardware mode.
The source procedure also disables antivirus protection temporarily before installing the driver components.
For safety, it is better to keep this temporary and re-enable your security software immediately after the required installation is complete.
Step 3: Install the MTK Driver
Extract the MediaTek driver package.Install the driver following the installer prompts.
The computer must be able to detect the Realme 3 correctly during the connection stage. Without the proper driver, the unlock utility may not be able to communicate with the phone.
The procedure also prepares the USBDK component as part of the PC-side setup.
Step 4: Prepare the Unlock Tool
Open the extracted bootloader unlocking tool.Locate the option related to Bootloader Unlock / UBL.
The procedure selects the bootloader unlock option and then confirms the operation from the computer.
Before proceeding, make sure the phone is sufficiently charged and that the USB cable is securely connected.
A notification may appear on the phone after the connection is established.
Before proceeding, make sure the phone is sufficiently charged and that the USB cable is securely connected.
Step 5: Connect the Realme 3 While It Is Powered On
Connect the Realme 3 to the computer while Android is still running.A notification may appear on the phone after the connection is established.
Follow the on-screen instructions and then power the phone off as directed by the unlocking procedure.
Do not disconnect the USB cable unless the procedure specifically instructs you to do so.
Keep both buttons pressed as the phone enters the required low-level connection mode.
Do not disconnect the USB cable unless the procedure specifically instructs you to do so.
Step 6: Enter the Required Hardware Mode
With the phone powered off, press and hold Volume Up + Volume Down simultaneously.Keep both buttons pressed as the phone enters the required low-level connection mode.
The process should be relatively quick. Once the tool detects the device correctly, release the buttons.
If the phone is not detected, check the USB connection and confirm that the MTK driver was installed correctly.
When the tool asks for confirmation, enter the required confirmation, such as Y, and press Enter.
The phone should then be processed by the tool.
If the phone is not detected, check the USB connection and confirm that the MTK driver was installed correctly.
Step 7: Start the Bootloader Unlock Process
Return to the computer and continue with the unlock tool.When the tool asks for confirmation, enter the required confirmation, such as Y, and press Enter.
The phone should then be processed by the tool.
Wait until the utility reports that the operation has completed. The described procedure indicates that the bootloader unlock finishes after this confirmation stage.
Do not interrupt the process while the tool is communicating with the phone.
Do not interrupt the process while the tool is communicating with the phone.
Step 8: Restart the Phone
Once the tool has completed the operation, disconnect the computer-side process as instructed and start the Realme 3 normally.
The device should boot back into Android.
The first boot after an unlock operation may behave differently from a normal restart, so allow the phone enough time to complete the startup sequence.
How to Confirm That the Bootloader Is Unlocked
There are several indicators described in the procedure that can help confirm the result.Orange Warning Text During Startup
After powering on the device, a small orange warning message appears during startup.This is described as an indication that the Realme 3 bootloader has been unlocked successfully.
OEM Unlocking Option
After Android has started, enable Developer Options by repeatedly tapping the Build Number.Open Developer Options and check the OEM unlocking entry.
According to the demonstrated procedure, the OEM unlocking option changes after the bootloader has been unlocked, providing another visual confirmation.
Step 9: Enable Developer Options
After the phone boots successfully:- Open Settings.
- Go to the phone information section.
- Find Build Number.
- Tap it repeatedly until Developer Options are enabled.
- Open Developer Options.
What Can You Do After Unlocking?
With the bootloader successfully unlocked, the Realme 3 can be prepared for more advanced customization.The next possible stages include:
- Custom Recovery: Install a compatible TWRP or other recovery.
- Root Access: Modify the system using an appropriate root solution.
- Custom ROM: Install a compatible aftermarket Android ROM.
Important Note About Recovery Mode
One detail worth knowing is that the standard hardware-button behavior may not immediately provide the recovery or bootloader interface expected after unlocking.The procedure notes that pressing and holding the volume-down button during restart does not necessarily open recovery and may simply result in a normal restart.
This does not necessarily mean that the bootloader unlock failed.
Further setup may be required to add or enable convenient access to Fastboot/Bootloader mode before installing TWRP or other modifications.
Troubleshooting
The PC Does Not Detect the Phone
Check the following:- Reinstall the MTK driver.
- Reconnect the USB cable.
- Try another USB port.
- Make sure the required hardware mode is entered correctly.
- Check whether the USB/MediaTek device appears correctly in Windows.
The Unlock Tool Does Not Respond
Close and reopen the tool, then verify the driver installation.Make sure the phone is connected at the correct stage of the procedure and repeat the hardware-button sequence carefully.
No Orange Warning Appears
Boot the phone again and observe the startup screen.The orange text is one of the indicators used by the procedure to confirm that the bootloader has been unlocked.
You can also check the OEM unlocking state in Developer Options.
Final Thoughts
Unlocking the Realme 3 bootloader is the foundation for deeper Android customization. The process starts by preparing the Windows PC with the necessary MTK driver and USBDK components, opening the appropriate unlock tool, connecting the powered-on phone, shutting it down, entering the required hardware mode with the volume buttons, and confirming the unlock operation.After the procedure completes, the appearance of the orange warning text at startup and the changed OEM unlocking state in Developer Options can be used as indicators that the bootloader is unlocked.
Once the Realme 3 is unlocked, you can move on to more advanced modifications such as custom recovery, root, or a custom ROM. However, those steps are separate procedures and should use files specifically compatible with the Realme 3.
Always keep a backup of your important data and verify every file before performing system-level modifications.
