Gaining root permissions on an Android device has always split users between the curious and the passionate. On the one hand are those who want to customize their operating system to the fullest; on the other, those who fear compromising the phone’s stability or security. Performing a root means obtaining full control of the device, becoming the “root user,” with the ability to modify system files, install custom recoveries, and use applications that require administrative privileges.

In this complete guide, we’ll see how to enable root permissions on Android, what unlocking the bootloader entails, which tools you need (from USB debugging to the USB cable), how to perform root even without a PC, and above all what risks and benefits are involved.

What is Root and what is it for

To understand how to get root permissions, you first need to clarify what root actually is. In the Linux environment on which Android is based, the term “root” refers to the user with administrative privileges—i.e., the one who can access and modify system files that are normally off-limits.

Consequently, obtaining root permissions means moving from being a simple user—limited by security settings and the manufacturer’s default settings—to becoming the device’s full administrator.

With root, you can:

• Remove preinstalled applications (bloatware).
• Install custom ROMs.
• Improve performance by tweaking kernel parameters.
• Automate functions with advanced apps like Tasker or Titanium Backup.
• Access hidden files in the Android operating system.

However, rooting can be risky, especially if you don’t follow instructions correctly or use tools that aren’t compatible with your specific device.

How to enable root permissions on Android

Let’s now look, practically, at how to enable root permissions on Android. The process may vary depending on the manufacturer (Samsung, Xiaomi, OnePlus, etc.), but in general it follows the same fundamental steps.

1. Check device compatibility

Not all Android devices can be rooted using the same procedure. It’s important to check on the manufacturer’s official website whether bootloader unlocking is allowed. Some brands, such as Huawei or Honor, have blocked this option for security reasons.

You can look for model-specific guides on forums like XDA Developers or on the manufacturer’s site.

2. Enable developer options

The first step to obtaining root permissions is enabling the Developer Options menu:

• Open Settings > About phone.
• Tap the Build number entry 7 times.
• Go back to the main menu and open Developer options.

Here you’ll find two essential settings: USB Debugging and OEM Unlocking.

3. Enable USB debugging and OEM unlocking

• USB Debugging lets your smartphone communicate with a computer via a USB cable to run ADB (Android Debug Bridge) commands.
• OEM Unlocking allows you to unlock the bootloader, a necessary condition for rooting.

After enabling both options, you can connect the phone to the PC and proceed to the next phase.

4. Unlock the bootloader

Bootloader unlocking is the key that opens the door to root. The bootloader is the component of the operating systemthat starts Android. Manufacturers lock it to prevent unauthorized modifications.

To unlock the bootloader, you generally use ADB and Fastboot. Here’s how:

adb reboot bootloader

fastboot oem unlock

Some models may require an unlock code provided by the manufacturer. Once the operation is complete, the device may reboot automatically and erase all data: therefore, it’s crucial to back up everything before proceeding.

5. Install a custom recovery

Once the bootloader is unlocked, you need to install a custom recovery (such as TWRP or ClockworkMod). These let you install ZIP files containing the rooting software and perform backup/restore operations.

Typical Fastboot command:

fastboot flash recovery twrp.img

After installation, boot the phone into recovery mode to move on to the next step.

6. Root with Magisk or SuperSU

Two of the safest and most widespread methods to root are Magisk and SuperSU. Both apps let you obtain root permissions and manage the permissions of applications that request them.

• Magisk is currently the most recommended solution because it allows a systemless root, i.e., without directly modifying system files, improving compatibility with banking apps and security checks.
• SuperSU, which is older, modifies system files and can cause problems with OTA updates.

To install Magisk:

• Copy the ZIP file to the device.
• Boot into the custom recovery.
• Select Install and choose the ZIP file.
• Reboot the system.

The device will reboot automatically with root permissions active.

7. Check whether root is active

After rebooting, you can verify whether root has been enabled by installing the Root Checker app from the Google Play Store. The app will check whether you are a root user and display a confirmation message.

If the result is positive, it means you’ve completed the procedure to enable root permissions on Android correctly.

How to enable root permissions on Android without a PC

Many users wonder whether it may be possible to perform root without using a computer. In some cases, yes. There are apps that allow you to obtain root permissions directly from your smartphone or tablet, without connecting it to a PC via a USB cable.

Among the best-known apps are:

• KingRoot
• Framaroot
• KingoRoot

These applications exploit operating system vulnerabilities to temporarily grant administrator privileges. However, they don’t always work with the latest versions of Android and may pose a risk to cyber security, since they require full access to the system.

Therefore, it’s advisable to use official methods and open-source tools such as Magisk.

Benefits and risks of root

Benefits

• Full control over the device.
• Ability to install advanced apps.
• Complete customization of the Android operating system.
• Full system backups and restores.

Risks

• Manufacturer’s warranty may be voided.
• Risk of bricking, i.e., rendering the device unusable.
• Security updates disabled or not installable.
• Possible exposure to malware or vulnerabilities.

Therefore, rooting is not something to do lightly. It requires awareness, caution, and—above all—a solid technical understanding of your own device.

Restore the original permissions

If, after some time, you want to return to your smartphone’s default settings, you can remove root. Generally, Magiskallows you to do this easily via the Magisk Manager app by selecting “Uninstall” > “Complete uninstall.”

Alternatively, you can reinstall the manufacturer’s original firmware (stock ROM), which will restore the system filesand the original bootloader.

How to protect a rooted device

A device with root permissions is a powerful, customizable machine, but precisely for that reason it also becomes a more vulnerable target. When you gain full access to the Android operating system, you remove some of the security barriers designed by manufacturers to protect your smartphone or tablet from intrusions, malware, and unauthorized changes to system files. In other words, you open the door to a freedom that can become a risk if the right protective measures aren’t taken.

To keep a rooted device safe, it’s essential to combine good digital hygiene with reliable security tools.

First of all, it’s crucial to install a trustworthy antivirus capable of scanning installed apps, monitoring network traffic, and blocking suspicious behavior. There are solutions designed specifically for root users, offering deeper control over processes and permissions and enabling the detection of unauthorized changes to system files.

Another key measure is to grant root privileges only to necessary apps. Every time an app requests root user access, ask yourself whether it truly needs it. Many types of malware try to exploit root to gain total control of the device. Using tools like Magisk Manager helps you monitor and manage authorization requests in real time.

It’s equally important not to download apps from unofficial sources. Alternative marketplaces may host modified versions of popular apps that include malicious code or scripts capable of altering security settings. Installing only from the Google Play Store or verified repositories is the safest choice.

Another recommended practice is to disable USB debugging when you don’t need it. USB debugging, enabled during rooting or for development operations, can be an entry point for remote attacks or unauthorized access by someone who physically connects the device to a computer. Leaving it enabled exposes your phone to unnecessary risks, especially in public or shared work environments.

Finally, it’s essential to keep the system up to date. Even if a device is rooted, it’s good practice to install security patches, Magisk updates, and the latest versions of management apps. Updates fix known vulnerabilities and improve root compatibility with new system versions.

For those who want to go further, you can also:

• Use an Android firewall to monitor inbound and outbound connections.
• Limit app permissions using dedicated managers.
• Perform regular backups to avoid data loss in case of errors or compromise.

Protecting a rooted device, therefore, doesn’t mean giving up customization freedom, but learning to use it consciously combining caution, constant updates, and appropriate security tools. Only then can you make the most of root while minimizing risks.

In short

Understanding how to enable root permissions on Android means entering advanced territory where freedom and risk coexist. Rooting can be useful for power users who want to customize every aspect of the operating system, but for those who use their smartphone or tablet for work or sensitive activities, it’s better to evaluate the implications carefully.

The advice is to do thorough research, verify the compatibility of your own device, and proceed only if you’re certain of what you’re doing. Poorly managed rooting can compromise the phone, while a correctly executed root can turn it into a powerful, tailor-made machine.
