Preparing Your Samsung Galaxy J4

Check Device Compatibility

Before proceeding with the rooting process, it’s crucial to ensure that your Samsung Galaxy J4 is compatible with Magisk. Not all devices can be rooted, and attempting to root an incompatible device may lead to it becoming inoperable.

To check compatibility, visit the official Magisk documentation and look for your device model in the supported list. If your device is not listed, it may still be possible to root, but additional research and caution are advised.

It’s important to verify the specific model number of your Samsung Galaxy J4, as different regions may have variations that affect compatibility.

Here’s a quick checklist to help you confirm compatibility:

  • Verify the model number in your device’s settings.
  • Check the processor architecture (ARM, ARM64, x86).
  • Ensure the Android version is supported by Magisk.
  • Look for any known issues with your device model on forums and community discussions.

Backup Data

Before proceeding with the rooting process, it’s crucial to back up all personal data on your Samsung Galaxy J4. This ensures that you can restore your information in case anything goes wrong during the rooting process. There are several methods to back up your data:

  • Use Samsung’s built-in backup feature in the settings menu.
  • Sync your data with your Samsung or Google account.
  • Manually copy files to a secure location, such as a PC or cloud storage.

Remember, while backing up application data, remember to check if the apps have cloud backup enabled. This will make it easier to restore app data after rooting your device.

After completing the backup, verify that all critical data is accessible and correctly stored in the backup location. This step is essential to avoid any data loss.

Enable Developer Options

To access the advanced settings required for rooting your Samsung Galaxy J4, you must first enable Developer Options. This hidden menu provides the necessary tools for the rooting process.

To enable Developer Options, follow these steps:

  1. Go to the ‘Settings’ app on your device.
  2. Scroll down and select ‘About phone.’
  3. Find ‘Build number’ and tap it 7 times rapidly. You will see a message indicating that Developer Options have been unlocked.

Once Developer Options are enabled, you will find the menu in the ‘Settings’ under ‘System’ or directly in the main settings list, depending on your device’s firmware version. It’s crucial to proceed with caution, as these settings can significantly affect your phone’s performance and functionality.

Installing Magisk Manager

Download Magisk Manager

To begin the rooting process, you’ll need to download the Magisk Manager app. This application is not available on the Google Play Store, so you’ll have to download it from a reliable source. Ensure that you download the latest version to avoid any compatibility issues.

  • Visit the official Magisk GitHub page or a trusted community forum.
  • Look for the ‘Magisk Manager’ APK file.
  • Download the APK to your Samsung Galaxy J4.

Before proceeding with the installation, make sure to check the APK file for any signs of tampering or malicious alterations. It’s crucial to maintain the security of your device throughout this process.

Install Magisk Manager

Once you have downloaded the Magisk Manager APK, you’re ready to install it on your Samsung Galaxy J4. Navigate to the APK file using a file manager of your choice and tap on it to begin the installation process. If you encounter a prompt asking to allow installation from unknown sources, go to your device’s settings and enable this option.

  • Open the file manager.
  • Locate the Magisk Manager APK file.
  • Tap on the APK to initiate installation.
  • If prompted, allow installation from unknown sources in settings.

After the installation is complete, you should see the Magisk Manager icon in your app drawer, signifying that the app is ready to use. This is a crucial step, as Magisk Manager will be the tool through which you will manage root permissions and install modules to customize and enhance your device’s performance.

Grant Necessary Permissions

After installing Magisk Manager, it’s crucial to grant the necessary permissions for the app to function correctly. Magisk Manager will request permissions such as storage and location. Ensure that you approve these to allow the app to operate without hindrances.

It’s important to note that granting these permissions is essential for Magisk Manager to access and modify system files, which is a critical step in the rooting process.

Here’s a quick rundown of the permissions you’ll need to enable:

  • Storage: To read and write files necessary for the rooting process.
  • Location: Used for modules that may require location information.
  • Telephone: For modules that interact with phone status and identity.

Remember, each permission has its purpose, and denying any of them might lead to a failed root attempt or limited functionality of Magisk Manager.

Rooting Your Samsung Galaxy J4

Download Magisk Zip

Before proceeding to root your Samsung Galaxy J4, you need to download the Magisk Zip file. This file is essential as it contains the software required to gain root access.

To ensure you download the correct version of Magisk Zip, follow these steps:

  1. Visit the official Magisk GitHub repository.
  2. Look for the latest stable release of Magisk Zip.
  3. Download the file to your device’s storage.

Make sure to remember the location where you save the Magisk Zip file as you will need to navigate to it when flashing it in the next steps.

Flash Magisk Zip

With the Magisk Zip file downloaded, you’re now ready to flash it onto your Samsung Galaxy J4. This is the critical step where Magisk is actually installed onto your device, providing you with root access.

Ensure your device is connected to your computer and that it’s in bootloader mode. Use the custom recovery tool to select the Magisk Zip file. The flashing process will begin; it usually takes a few minutes to complete. Do not interrupt this process as it could lead to system instability or even bricking your device.

Once the flashing is complete, you’ll see a confirmation message on the screen of your custom recovery tool. Before you proceed to the next step, it’s important to clear the cache on your device. This can help prevent any potential issues with boot loops or system errors after rooting.

After flashing Magisk, it’s crucial to reboot your device to finalize the rooting process. This allows the system to integrate the new changes and for Magisk to start operating effectively.

Reboot Your Device

Once you have flashed the Magisk Zip file, the final step is to reboot your device. This is crucial to finalize the rooting process and to activate Magisk’s features. After the reboot, your Samsung Galaxy J4 should be successfully rooted with Magisk.

Please be patient during the first boot after rooting as it may take longer than usual. This is normal as the system is configuring itself with the new root settings.

To verify that your device is rooted, you can follow these steps:

  1. Open the Magisk Manager app.
  2. Check for a green checkmark next to ‘Magisk is installed’.
  3. If you see the green checkmark, congratulations, your device is now rooted!

Remember, with great power comes great responsibility. Rooting your device gives you more control but also requires careful management of permissions and system modifications. Enjoy your newly rooted Samsung Galaxy J4 responsibly!
