Preparing Your Device

Check Device Model

Before proceeding with the rooting process, it’s crucial to verify that your device is a Samsung Galaxy A31. Rooting the incorrect model can lead to irreparable damage. To check your device model, go to ‘Settings’ > ‘About phone’ > ‘Model number’. Ensure that the model number matches one of the following:

  • SM-A315F
  • SM-A315G

It’s essential to match the exact model number, as different regions may have variations in hardware that affect the rooting process.

If your device model does not match, do not continue with this guide. Rooting is a model-specific procedure, and using the wrong files can brick your device.

Backup Data

Before proceeding with the rooting process, it’s crucial to back up all the data on your Samsung Galaxy A31. Data loss can occur during rooting, and having a backup ensures that your personal information, apps, and media are safe. Use Samsung’s built-in backup feature or a third-party app to secure your data.

It’s recommended to back up to an external source such as a PC or cloud service to prevent any data loss during the rooting process.

Here’s a simple checklist for backing up your data:

  • Sync your accounts (Google, Samsung, etc.)
  • Use Samsung Smart Switch to back up to a PC
  • Backup photos and videos to Google Photos or another cloud service
  • Save a copy of your contacts to your SIM card or cloud
  • Don’t forget to backup SMS, call logs, and app data if needed

Enable Developer Options

To access the developer options on your Samsung Galaxy A31, you’ll need to unlock this hidden menu. Navigate to your device’s settings, scroll down to ‘About phone’, and tap on ‘Software information’. Here, you’ll find the ‘Build number’. Rapidly tap on the ‘Build number’ seven times. A message will appear informing you that developer options have been enabled.

Once developer options are unlocked, return to the main settings menu. You should now see ‘Developer options’ listed—this is where you can enable USB debugging and OEM unlocking, which are crucial for the rooting process.

Remember, enabling developer options exposes sensitive settings that can affect your device’s functionality. Proceed with caution and only adjust settings that are necessary for the rooting process.

Unlocking Bootloader

Request Unlock Code

Before you can unlock the bootloader on your Samsung Galaxy A31, you need to request an unlock code from Samsung. This is a crucial step as without the code, you won’t be able to proceed with the rooting process.

To request the unlock code, follow these steps:

  1. Visit the official Samsung Developer website.
  2. Sign in with your Samsung account or create a new one if necessary.
  3. Navigate to the ‘Unlock Bootloader’ section.
  4. Enter your device’s model number and serial number.
  5. Submit the form and wait for the unlock code to be emailed to you.

Remember, the unlock code is unique to your device and should be kept confidential. Do not share it with others as it could compromise the security of your device.

Unlock Bootloader

Once you have your unlock code, it’s time to proceed with the bootloader unlocking process. This step is crucial as it allows you to install custom software on your Samsung Galaxy A31.

Follow these steps to unlock the bootloader:

  1. Power off your device.
  2. Boot into download mode by holding the Volume Down, Power, and Home buttons simultaneously.
  3. When the warning screen appears, press the Volume Up button to enter download mode.
  4. Connect your device to your PC using a USB cable.
  5. Open the command prompt on your PC and navigate to the ADB installation folder.
  6. Enter the command fastboot oem unlock YOUR_UNLOCK_CODE replacing YOUR_UNLOCK_CODE with the code you received.

After completing these steps, your device will reboot, and the bootloader will be unlocked. It’s important to note that unlocking the bootloader may void your warranty and erase all data on the device, so ensure you have backed up important information.

To verify that the bootloader is unlocked, you can reboot your device into download mode again. If you see a message stating ‘Unlocked’, the process was successful. If not, you may need to repeat the steps or troubleshoot any issues that occurred during the process.

Verify Bootloader Status

Once you have completed the bootloader unlocking process, it’s crucial to verify that your Samsung Galaxy A31 is indeed ready for the next steps. Boot into the device’s fastboot mode to check the bootloader status. This can typically be done by turning off your device, then holding the power and volume down buttons simultaneously until the fastboot screen appears.

To confirm the bootloader status, use the fastboot command:

fastboot oem device-info

The output should display a message indicating that the bootloader is unlocked. Here’s what you might see:

Device unlockedtrue
Charger connectedfalse
Battery levelHigh

Ensure that the ‘Device unlocked’ variable is set to ‘true’. If it’s not, you may need to revisit the previous steps to successfully unlock the bootloader.

If everything checks out, you’re ready to proceed with installing Magisk Manager, which will bring you one step closer to gaining root access on your Samsung Galaxy A31.
