Obtaining superuser rights, or root accessopens up unlimited possibilities for the smartphone owner to customize and optimize the system. However, the process of turning a regular user into a device administrator is fraught with serious risks, including loss of warranty and the possibility of turning the gadget into a “brick.” In this article, we will analyze in detail the modern algorithm of actions necessary to make the device root Androidusing current tools and methods.
The modern security ecosystem Android has significantly complicated hacking procedure compared to earlier versions of the OS. If previously it was enough to launch one application, now the process requires deep intervention in the boot partitions. You have to not just install the app, but modify the system image boot.img, which requires understanding the architecture of the file system of your smartphone.
Before starting any manipulations, it is critically important to realize that unlocking the bootloader automatically erases all user data. This is a built-in security mechanism that cannot be bypassed by software. Therefore, the first and most important step is to create a complete backup copy of all important information on external media or in cloud storage, since restoring deleted files after formatting will be impossible.
Preparation of tools and diagnostics of the device
The success of the operation depends 90% on the quality of preparation of the workplace and software. You will need a personal computer with ADB and Fastbootdrivers installed. Without these utilities, communication between a PC and a smartphone in bootloader mode will be impossible. You can download them as part Android SDK Platform-Tools from the official website of the developers.
You also need to enable USB debugging mode on the smartphone itself. 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 section For developers and activate the switch USB debugging. This will allow the computer to send commands to the device.
Special attention should be paid to the condition of the battery. The battery charge should be at least 60-70%. Interrupting the firmware process due to a discharge may result in irreversible damage to the bootloader. In addition, make sure that you are using an original or high-quality certified cable that is capable of transferring data, and not just charging the device.
- 🛠️ Installed ADB and Fastboot drivers on the PC
- 🔋 Smartphone battery charge is above 60%
- 💾 Full backup data
- 🔌 Original USB data cable
⚠️ Attention: Using unsuitable drivers or a damaged cable may result in the computer not seeing the device in Fastboot mode, which will interrupt the procedure at the very start.
☑️ Ready for rooting
Unlocking the bootloader
The bootloader is a app that runs in front of the operating system and verifies the digital signatures of loaded components. Manufacturers block it to prevent the installation of unverified software. To make the device rootthis protection must be removed. The process is unique for each brand: it requires a wait of 7 to 15 days and a special Mi Unlock utility, and the command is entered directly through the console. Make the device root. data-i="73">For devices with an unlockable bootloader, the procedure usually looks like this: switch the smartphone to Fastboot mode (most often by pressing the volume down button when connecting to a PC). Then, in the computer command line, enter the command to test communication: Xiaomi requires a wait of 7 to 15 days and a special Mi Unlock utility, and Pixel or OnePlus the command is entered directly through the console.
For devices with an unlockable bootloader, the procedure usually looks like this: put the smartphone into Fastboot mode (most often by pressing the volume down button when connecting to a PC). Then, at your computer's command prompt, enter the following command to test connectivity:
fastboot devicesIf the device is displayed in the list, you can send an unlock command. On many smartphones it looks like fastboot flashing unlock or fastboot oem unlock. A data loss warning will appear on your phone screen. Confirm the action with the volume buttons. After the reboot, the device will be completely cleared, and the bootloader status will change to “Unlocked.”
Nuances of unlocking Samsung
On Samsung smartphones, the process is different: instead of Fastboot, Download Mode is used (a combination of the volume and power buttons), and unlocking is done through specific Odin commands or directly in the bootloader menu, where you need to press and hold the volume up button to confirmation. This may void the warranty and trigger the Knox counter, irreversibly disabling Samsung Pay and Secure Folder.
Searching and modifying the boot partition image
The most reliable and modern method of obtaining root access is using a manager Magisk. Unlike older methods that directly modified the system partition, Magisk is applied to the boot image. This allows you to gain root access system-free, that is, without changing system files, which increases stability and allows you to hide the presence of rights from banking applications. /systemMagisk is applied to the boot image boot.img. This allows you to gain root access system-free, that is, without changing system files, which increases stability and allows you to hide the presence of rights from banking applications.
You need to find the exact version of the firmware that is currently installed on your smartphone. Download the official ZIP archive with firmware from the manufacturer’s website or a trusted resource like Sammobile or XiaomiFirmware. Extract the file boot.img from the archive (sometimes init_boot.img on new models with Android 13+). Copy this file to the internal memory of the phone.
Install the Magisk application (apk file from the official GitHub repository). Launch it, click the “Install” button in the Magisk block and select “Patch the boot image”. Specify the previously copied file. The application will create a modified version of the file with a name like magisk_patched_[random].img in the Download folder.
- 📂 Download the exact firmware version for your model
- 📱 Extract the boot.img or init_boot.img file
- 🔨 Use Magisk to patching the image
- 💾 Return the patched file to the computer
If you cannot find the boot.img file in the firmware, try unpacking the payload.bin image (for Pixel and some others) using the payload_dumper utility to gain access to the necessary partitions.
Flashing the modified image via Fastboot
After creating a patched image, it must be written to the boot partition of the device. Put your smartphone into Fastboot mode again and connect it to your PC. Make sure that the file magisk_patched.img is located in the platform-tools folder on your computer for ease of entering commands.
Enter the command to burn the image. The syntax may vary depending on the processor architecture and Android version. For most devices, the command is relevant:
fastboot flash boot magisk_patched.imgOn devices with a partition init_boot (for example, Google Pixel 7/8, Xiaomi 13 and newer) the command will look different:
fastboot flash init_boot magisk_patched.imgAfter successful recording, enter the command fastboot reboot to reboot. If your device boots normally, open the Magisk app. If the version number is displayed in the “Magisk” line and the “Installed” status is active, congratulations - you have successfully made the device root.
⚠️ Attention: If after flashing the phone the phone goes into a cyclic reboot (bootloop), immediately boot into recovery or fastboot mode and flash the original (unpatched) boot.img file to restore system functionality.
Setting access rights and hiding root
Having root access in itself does not give access to all functions at once. Applications that require superuser privileges will ask for permission the first time they are launched. In the Magisk interface, you can manage these requests by granting or denying access to specific apps. This is an important element securitythat prevents unauthorized access of malware to the system.
Many banking applications and services (Google Pay, Mir Pay) refuse to work on rooted devices. To solve this problem, Magisk has a feature called Settings → Zygisk (enable) and Hide Magisk App (rename package). Additionally, it is recommended to install the module Shamiko or configure the DenyList, excluding banking applications from it in order to hide the presence of modifications.
It is also worth mentioning expansion modules. The module store inside Magisk allows you to install various tweaks: from changing fonts and animations to overclocking the processor and improving sound. However, install only proven modules, since incompatible software may cause instability. Android.
| Action | Risk | Complexity | Impact on warranty |
|---|---|---|---|
| Unlocking bootloader | High (data loss) | Medium | Warranty void |
| Patching boot.img | Medium (risk of bootloop) | High | Depends on testing during repair |
| Installing Magisk modules | Low (software conflicts) | Low | Can be hidden |
| Using banking applications | Access blocking | High (requires configuration) | Does not affect |
Modern rooting via Magisk is a reversible process: by flashing the original boot.img, you will completely remove traces of interference, which can help with warranty service if physical unlocking of the bootloader was not recorded by the service.
Possible problems and methods for solving them
During the rooting process, users often encounter the “Verification” error failed" or endless loading. This occurs if the integrity of the boot image is compromised or the signature does not match. In such situations, you need to return to the step with the original firmware and repeat the patching procedure, making sure that the file version 100% matches the installed system. Another common problem is the lack of Internet after flashing the firmware on some models. This is due to corruption of the NVData partition. To avoid this, before unlocking the bootloader, it is strongly recommended to dump the partition boot.img 100% consistent with the installed system.
Another common problem is the lack of Internet after flashing the firmware on some models MediaTek. This is due to corruption of the NVData partition. To avoid this, it is highly recommended to dump the partition before unlocking the bootloader persist or NVData via ADB commands in order to be able to restore IMEI and network settings in case of a failure.
⚠️ Attention: Settings interfaces and partition names may differ depending on the version of Android and the manufacturer's shell. Always check the relevant threads on the 4PDA or XDA forum for your specific model before entering commands.
What is SafetyNet and how to get through it?
SafetyNet is a system integrity check service from Google. To complete it on a rooted device, you need to activate Zygisk in the Magisk settings and use modules like Play Integrity Fix. Without this, some applications (banks, games with anti-cheat) will not start.
Is it safe to root on modern Android?
The procedure has become safer thanks to the Magisk system, which does not directly change the system partition. However, risks remain: an error when unlocking the bootloader or flashing the wrong file can lead to the device becoming inoperable. In addition, some applications (banks, games) can block operation on rooted devices.
Will the warranty expire after obtaining root access?
Formally, yes, unlocking the bootloader is grounds for refusal of warranty service from most manufacturers (Xiaomi, Samsung, OnePlus). However, if you return the original firmware and lock the bootloader (where possible), the fact of the intervention can be hidden, although electronic counters (for example, Samsung's Knox) may remain disabled forever.
Is it possible to remove root access and return everything to the way it was?
Yes, this is possible. The Magisk app has a “Remove Magisk” button that restores the original boot image. After this, you need to re-lock the bootloader with the command fastboot flashing lock (if the manufacturer allows) and perform a factory reset to make the device look like new.
Will the phone be updated over the air (OTA) after rooting?
Usually no. Modifying the boot partition violates the digital signature of the system, and the update servers will reject the OTA installation. To update, you need to temporarily remove the root (restore the original boot.img), install the update, and then patch the new image again via Magisk.
