Preparing Your Device

Check Device Model

Before proceeding with the rooting process, it’s crucial to ensure that you have the correct model of the Samsung Galaxy A03s. The model number should be SM-A037M; rooting a device with an incorrect model number can lead to bricking.

To check your device model:

  1. Go to ‘Settings’ on your phone.
  2. Scroll down and select ‘About phone’.
  3. Look for ‘Model number’ and confirm that it reads ‘SM-A037M’.

It’s important to double-check this information as the rooting process is specifically tailored for this model and may not be compatible with others.

Backup Data

Before proceeding with the rooting process, it’s crucial to backup all important data on your Samsung Galaxy A03s. Data loss can occur during rooting, and having a backup ensures you can restore your personal information if needed. Use Samsung’s built-in backup feature or a trusted third-party app to secure your files, contacts, messages, and app data.

  • Connect your device to a Wi-Fi network.
  • Go to Settings > Accounts and backup > Backup and restore.
  • Select the data you want to backup and tap ‘Back up now’.

Remember, while cloud services are convenient for backups, you can also use a PC or an external storage device for added security. Make sure to verify the backup completion before moving to the next steps.

Enable Developer Options

To enable Developer Options on your Samsung Galaxy A03s, you’ll need to access the ‘About phone’ section in your device settings. Here, locate the ‘Build number’ and tap it seven times. A message will appear indicating that you are now a developer. This step is crucial as it allows further customization and access to advanced settings.

Once Developer Options are enabled, you can proceed to the next steps:

  • Navigate back to the main settings menu.
  • Scroll down and you’ll see ‘Developer Options’.
  • Tap to open and explore various settings.

Remember, while Developer Options can provide powerful tools for customization, they should be used with caution. Incorrect settings can affect your device’s performance.

Unlocking Bootloader

Request Unlock Code

Before you can unlock the bootloader on your Samsung Galaxy A03s, you’ll need to request an unlock code from Samsung. This is a crucial step as the code is unique to your device and is required to proceed with the unlocking process.

To request your 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 IMEI number and other required details.
  5. Submit the request and wait for the unlock code to be emailed to you.

Once you receive the unlock code, keep it handy as you will need it in the subsequent steps to unlock the bootloader. It’s important to note that the process may take a few days, so patience is key.

Unlock Bootloader

Once you have received the unlock code for your Samsung Galaxy A03s SM-A037M, it’s time to proceed with unlocking the bootloader. This is a critical step as it allows the installation of custom software, such as Magisk, which is necessary for rooting your device.

To unlock the bootloader, follow these steps:

  1. Power off your device.
  2. Boot into download mode by holding the Volume Down, Volume Up, and Power buttons simultaneously.
  3. When prompted, press the Volume Up button to enter ‘Device Unlock Mode’.
  4. Enter the unlock code provided by the manufacturer.

After completing these steps, your device will reboot, and the bootloader will be unlocked. It’s essential to proceed with caution as this process may void your warranty and can potentially brick your device if not done correctly.

Verify Bootloader Status

Once you have attempted to unlock the bootloader on your Samsung Galaxy A03s SM-A037M, it’s crucial to verify that the process was successful. Boot into the device’s fastboot mode and use the command fastboot oem device-info. The output should indicate the bootloader status. If the status is ‘Unlocked’, you can proceed with the rooting process.

  • Power off your device.
  • Press and hold the Volume Down + Power buttons to enter fastboot mode.
  • Connect the device to your PC via USB.
  • Open a command prompt or terminal on your PC.
  • Type fastboot oem device-info and press Enter.

If the bootloader status is still ‘Locked’, you may need to revisit the previous steps to ensure you have followed all instructions correctly. It’s important not to skip any steps or rush the process, as this can lead to issues with your device.
