The operating systems you use daily on your computers and on your mobile devices integrate security systems that prevent users from making changes considered in some way “dangerous” and which could affect the stability of the software. In some cases, however, circumventing such systems can be useful: this procedure is commonly identified as rooting and today I would like to talk about it in more detail. How to have root permissions?

 

If, therefore, you are interested in how to do it but you do not have the faintest of how to have root permissions on your devices. I have good, indeed excellent news for you: below are all the explanations you need! In fact, during this guide. I will list you what are the steps to be taken to enable advanced permissions on the most common mobile and desktop platforms: Android, iOS / iPadOS, Windows and macOS.

 

So, I invite you to make yourself comfortable and focus carefully on reading the following lines: I am sure that, in the end. You will be more than satisfied and that. If necessary, you will also be able to explain to all your friends how to get the same result. Let it bet?

 

What are root permissions

Before getting to the heart of this guide and explaining, in concrete terms, how to obtain root permissions , let me give you some more information about the consequences of this operation.

 

Basically, having root permissions means authenticating in the operating system in use with elevated privileges , in order to overcome any security restrictions imposed by the system itself or by the device manufacturer, and to be able to freely change all those settings that, in “normal” conditions would remain inaccessible.

 

For this reason, the release of these permits allows access to areas of the system otherwise inhibited, increasing their degree of action and customization; on the other hand, however, an incorrect use of root privileges can lead to unpleasant consequences: for example, an apparently harmless Android app, if run with root permissions, can make unexpected changes to the system (e.g. the installation of spyware, malware or, worse, ransomware); on the computer, however, the execution of an incorrect command in root mode could have the direct consequence of the impossibility of accessing the operating system again.

 

Let me explain: if, absurdly, I tried to delete a system file with non-root access, Windows or Linux would prevent you from doing so, giving you an access denied error; with active root permissions, however, you would be able to safely delete that file, without any hitch, then realizing the error when it would be too late.

 

For this reason, I urge you to use elevated system privileges prudently and to act only in full awareness of what this may entail. Then don’t say I didn’t warn you! I will not take any responsibility in this regard.

 

How to have root permissions on Android

If you have an Android- based device and you want to unlock the operating system to obtain root permissions, I have to give you a not very positive news: unfortunately, in the current state of things, there is no single procedure for unlocking all devices equipped with the green robot operating system.

 

The procedures, in fact, may vary not only according to the manufacturer, but also according to the precise model of Android device in one’s possession; what I want to say, in practice, that the procedure for having root permissions on Huawei could differ significantly from that for obtaining the same result on a Samsung , Google , Sony , Xiaomi terminal and so on. What I can do, however, is to provide you with some general indications on the steps to be taken to succeed in the business.

 

Create a data backup :
  • Since the device will have to be unlocked by the bootloader, an operation that involves the total loss of the data stored in the memory, it would be advisable to secure your personal data. In this regard, I recommend that you rely on the tools that I mentioned in my Android backup guide or my tutorial on how to backup Huawei .

Unlock the bootloader :
  • For your information, the bootloader is a small application run immediately after the phone or tablet is turned on. Capable of verifying the integrity of the operating system and running it. The bootloader is blocked on almost all existing smartphones or tablets. For security reasons but, in order for the root procedure to be successful. It is necessary to unlock it. The steps necessary to perform this operation differ from device to device. On Samsung, for example, simply enable the development options and activate the lever for OEM unlocking. Xiaomi, however, you can request the unlocking of the device through a free PC program;on some Motorola. However, it is necessary to request the unlock code directly from the manufacturer; Pixel or Nexus smartphones, on the other hand, allow you to unlock via ADB , giving the command fastboot flashing unlock, or the command fastboot oem unlock, if the device was produced before 2015. For more detailed information on the operations to be performed, specifically, on your device, search on Google for phrases like unlocking bootloader [device brand and model] . Regardless of the method used, you must be aware that, following the unlock procedure of the bootloader, all the data present in the device will be deleted .

 

Install the TWRP recovery :
  • Recovery is software external to Android that allows you to intervene deeply on the operating system. Carrying out operations such as flashing (i.e. adding functions to the operating system, or replacing it, through a file. ZIP). Unless you are using a device that already has an advanced factory installed recovery (like some Samsung, for example). You can install TWRP by following the instructions I provided in my tutorial on how to return to the previous version of Android.

 

Flash the APK that enables the root :
  • Once the recovery installation is complete. You must copy the APK file relating to the app you intend to use to obtain advanced permissions on the operating system. The best known apps of this type. At the time of writing this guide, they are Magisk and SuperSU. If, on the other hand. You use a Samsung device, you can act using ODIN. A PC program capable of flashing ROMs and apps in .ZIP format, without going through recovery.

 

 

To get more specific information about the steps you need to take to activate root permissions on your specific device. You can search on Google for phrases such as enabling root [device brand and model]. Also, I recommend that you take a look at my guide on how to root Android. In which I told you about it in more detail.

 

Remember, in any case, that unlocking root permissions on Android can prove dangerous. Do not allow root access to apps that you do not know exactly the “connotations” because, in doing so. You would provide full action permissions on the entire operating system.

 

 

How to have root permissions on Linux

If you intend to obtain administrative privileges on Linux distributions. A recommendation is a must: root permissions provide almost uncontrolled access to all parts of the operating system. Even the most delicate ones. So, use this mode only if you are well aware of what you are about to do. A single incorrect command could compromise the functioning of the entire operating system. I warned you!

 

However, there are many ways to get root permissions on Linux. For example, if you are interested in running a program in elevated mode directly from the Terminal. You can issue the command in the latter sudo nome Programma(e.g. sudo gedit, to open the GNOME text editor with administrative privileges) followed by pressing the Enter key of the keyboard: following this operation. You will be asked to enter the administrative password of the computer after that, The required software will be started with administrative privileges.

 

If, on the other hand. You have to issue several instructions in sequence. Run the command sudo -sfollowed by pressing the Enter key. When prompted, enter the Linux administration password. Starting from this moment, all the other commands given inside the Terminal will run with administrative privileges. When you’re done, don’t forget to exit root by typing the command exit.
