Receiving root access on a device with the Android operating system gives the user access to deep system settings that are usually hidden by the manufacturer. This allows you to remove pre-installed junk, change the system beyond recognition, and install specialized applications for power or processor management. However, this procedure is associated with serious risks, including loss of warranty and potential “bricking” of the smartphone if done carelessly.
Many enthusiasts wonder whether it is worth spending time hacking the system to expand functionality. The answer depends on your goals: if you need maximum performance or specific modules, then rooting necessary. Otherwise, for the average user, modern versions of Android provide a sufficient set of capabilities without the need to interfere with system files.
Before you begin, it is important to understand that the process is not universal for all models. Different manufacturers, such as Samsung, Xiaomi or Pixel, use different protection and unlocking methods. Below we will analyze in detail the stages of preparation, the necessary tools and ways to implement superuser rights in your firmware.
Preparation of the device and mandatory security measures
The first and most critical step is to create a complete backup of all data. The process of obtaining superuser rights often requires completely wiping the internal memory of the device. Make sure that your photos, contacts and documents are saved on external media or in cloud storage.
You also need to activate developer mode. To do this, go to Settings → About phone and quickly click 7 times on the item Build number. After the message “You have become a developer” appears, go to the new menu For developers and enable the option USB debugging. Without this item, the computer will not be able to interact with the smartphone at a deep level.
⚠️ Attention: Unlocking the bootloader (Bootloader) in most cases automatically erases all data from the device and may permanently void the manufacturer's warranty.
Download and install the ADB and Fastboot drivers on your computer. These utilities are a standard tool for communicating with Android devices via the command line. Check the cable connection: use the original cable or a high-quality analogue that supports data transfer, and not just charging.
Unlocking the bootloader
The bootloader is a app that runs before the operating system and verifies the digital signature of the loaded software. Most manufacturers block it to prevent the installation of unofficial firmware. The unlocking procedure is unique for each brand.
On devices Xiaomi and Redmi requires the official Mi Unlock utility and linking the account to the device for a period of 7 to 15 days. At the same time, for Google Pixel or OnePlus it is enough to execute the command in Fastboot mode. Devices from Huawei in recent years are practically impossible to officially unlock without obtaining special codes through third-party services.
- 🔓 For Samsung: combination of volume buttons and use of Download Mode with confirmation via command
adb reboot bootloader. - 🔓 For Xiaomi: hold down the buttons
Volume down + Powerand connect to the Mi Unlock Tool app on the PC. - 🔓 For Moto: obtaining a unique unlock code on the official Motorola Support website.
After successful unlocking, a warning that the device is not certified often appears on the boot screen. This is fine. Now the phone is ready to install custom recovery or directly implement root access through patching the image.
Installing custom recovery TWRP
Standard recovery menu (Stock Recovery) has limited functionality and does not allow you to install modified files. TWRP (Team Win Recovery Project) is the most popular custom recovery that provides full access to the file system.
To install, you will need to find an image twrp.imgcreated specifically for your smartphone model. Download it from the official website of the project or trusted forums such as 4PDA or XDA Developers. Place the file in the ADB tools folder on your computer.
fastboot flash recovery twrp.imgAfter entering the command, the device will overwrite the standard recovery. It is important not to boot into the system immediately after flashing the firmware, but to press the button combination to enter Recovery mode. If you boot into Android right away, the stock system can automatically replace TWRP back to its original bootloader.
If the recovery button does not work, use the adb reboot recovery command immediately after flashing the image, without disconnecting the cable.
Introducing superuser rights through Magisk
On today Magisk is the de facto standard for obtaining root access. Its main advantage is the systemless approach, which allows you to obtain rights without directly changing the section /system. This increases the chances of successfully passing security checks (SafetyNet/Play Integrity).
The process begins by downloading the official firmware image (boot.img or init_boot.img) corresponding to your current system version. This file needs to be transferred to your smartphone, open the Magisk application and select “Install” → “Select and patch file”. The application will create a modified image with the suffix _patched.
| Stage | Action | Result |
|---|---|---|
| 1 | Copying boot.img | File on device |
| 2 | Patching in Magisk | File patched_boot.img |
| 3 | Flashing via Fastboot | Activation of Root |
The final step is to return the modified file to the computer and flash it via Fastboot mode. The command depends on the partition structure of your device: most often used fastboot flash boot patched_boot.img. For new devices with a partition init_boot the command will be similar, but indicating the corresponding partition.
⚠️ Attention: Never try to flash an image from a different phone model or another version of Android. This is guaranteed to cause the device to malfunction (hard brick).
☑️ Checking the Root installation
Checking operation and setting up access
After rebooting the device, make sure that the Magisk application appears in the menu. Open it and check the status: the "Magisk" line should show the version, and the "Root" status should be active. For a detailed check, you can install the utility Root Checker from the application store.
When you first launch an application that requires elevated privileges, a system window will appear on the screen asking you to grant access. You can select Grant, Deny, or Temporary Only. Proper management of these requests is critical for security.
It is recommended to enable the function Zygiskin the settings of Magisk itself. It allows you to run Magisk code in the Zygote process, which is necessary for many modern modules to work and hide root access from banking applications. It is also worth activating the “Isolated Process” to increase system stability.
What to do if Magisk does not see root?
Try to reflash the image again, making sure you took the correct boot.img. Sometimes clearing the Dalvik/ART cache in Recovery mode helps.
Risks and limitations after obtaining Root
Having superuser rights changes the status of the device in the eyes of many services. Banking applications such as Sberbank, Tinkoff or Google Paymay refuse to work if they detect a modified environment. This is done to protect financial transactions from fraud.
In addition, some streaming services, for example Netflix, can reduce the quality of content playback to SD, since the integrity of the DRM trust chain (Widevine L1) is violated. Restoring a high level of protection after unlocking the bootloader can be extremely difficult, and sometimes impossible.
- 📉 Loss of warranty: service centers easily detect the fact of unlocking by the counter Knox (on Samsung) or the bootloader flag.
- 🔒 Blocking applications: banking software requires hiding root through modules type Play Integrity Fix.
- ⚡ Security risk: malware with root access can cause irreparable damage to the system.
⚠️ Attention: Settings interfaces and unlocking methods may change with Android updates. Always check the latest instructions for your specific firmware version on specialized forums before starting work.
However, for advanced users, the advantages outweigh the disadvantages. The ability to make full backups via Titanium Backup, block advertising at the system level and fine-tune processor frequencies makes root access a powerful tool in the hands of a knowledgeable person.
The main risk of getting root is not a technical breakdown, but the loss of access to banking applications and payment systems without the possibility of quick recovery.
Frequently asked questions (FAQ)
Will my applications be reset after rooting?
Yes, in 99% of cases, the process of unlocking the bootloader, which is a mandatory step, initiates a full reset of the device to factory settings (Wipe Data). All personal data will be deleted.
Is it possible to remove root access and return everything as it was?
Yes, this is possible. The Magisk app has a "Full uninstall" feature that restores the original boot image. However, if the guarantee counter (for example, Knox) was triggered, it cannot be returned to its original state programmatically.
Will Google Pay stop working after rooting?
By default, yes, it will stop. But with the use of Magisk modules (for example, Play Integrity Fix) and the inclusion of Zygisk, you can successfully hide the presence of root access and resume contactless payment.
Is it dangerous to give root access to unknown applications?
Extremely dangerous. An application with superuser rights has full control over the system: it can read passwords, delete files, turn on the camera without your knowledge. Trust access only to trusted software.
