How to open root access on Android: a complete guide with risks and solutions

Getting root access on Android opens access to hidden system functions, but turns the smartphone into a “wild field” for experiments - with risks and opportunities. Without root, you will not be able to remove built-in applications from the manufacturer, change system files or overclock the processor, but you will not face blocking of banking applications or loss of warranty. This article will help you weigh the pros and cons, choose the appropriate method and avoid common mistakes.

We will look at current methods for modern devices (including models with a locked bootloader), we will understand terms like Magisk, TWRP and bootloader unlock, as well as Let's explain why some phones (for example, Google Pixel or Samsung Galaxy latest generations) require a special approach. If you are a beginner, start with the section on risks. If you have already tried and encountered problems, go to the block on solving errors.

What are root access and why you need them?

Root (from the English “root”) is administrative access to the Android operating system, similar to superuser rights in Linux. With it you can:

• 📱 Delete pre-installed applications (bloatware) from the manufacturer or telecom operator.
• ⚡ Overclock the processor or video accelerator to improve performance in games.
• 🔧 Modify system files: change animations, fonts, icons, or even the version of Android.
• 📡 Block ads at the system level (for example, through AdAway).
• 🔄 Make full backups of all data, including applications with their settings.

However, with opportunities come limitations. Many banking applications (for example, SberBank Online or Tinkoff) refuse to work on rooted devices due to the risk of hacking. Some games (like Pokémon GO or Genshin Impact) they can ban your account for using modified clients. And over-the-air updates (OTA) will stop coming - you will have to install them manually.

⚠️ Attention: On devices with Samsung Knox (for example, Galaxy S23 or Galaxy Z Fold5) obtaining root will cause the flag to be irreversibly triggered. Knox 0x1. This will deprive you of the ability to use Samsung Pay, Secure Folder and some corporate functions.

Preparing the phone: what to do before getting root

Before you begin, follow the required steps - they will save time and nerves:

1. Create a backup copy Root can lead to resetting. settings or loss of files. Use Google Drive, Titanium Backup (if you already had root) or transfer the files to your computer.
2. Charge your phone at least up to 70%. Interruption of the process due to low battery is fraught with “bricking” (turning into a “brick”).
3. Find out the model and firmware version. Go to Settings → About phone and write down:
   • Device model (for example, Redmi Note 12 Pro+ 5G).
   • Android version (for example, 13 MIUI 14.0.5).
   • Build number (Build number).

For some brands (for example, Xiaomi or Huaweiyou will need to obtain permission to unlock through the official website. Samsung the procedure is more complicated - you need special tools like Odin and firmware files. Check the details for your model on the forums. XDA Developers or 4PDA.

How to unlock the bootloader

Bootloader (bootloader) is a app that launches Android when you turn on the phone. By default, it is locked to prevent unauthorized changes to the system. Unlocking erases all data from the device, so we repeat: make a backup.

Instructions for most devices (except Samsung i Google Pixel, they have their own nuances):

1. Enable developer mode:
   • Go to Settings → About phone.
   • Press 7 times on Build number (Build number).
   • Enter the PIN code if required.

adb reboot bootloader

U Xiaomi you will additionally need to link your account Mi to the device and wait 7 days (72 hours on some models) before unlocking. U Samsung instead of fastboot mode Download Mode and app Odin.

⚠️ Attention: On devices with MediaTek (for example, Realme 9 Pro or POCO X5) unlocking the bootloader may lead to loss of IMEI. Before the procedure, save it using the application MTK Engineering Mode.

Ways to obtain root access: which one to choose

There are three main methods, and the choice depends on the phone model, Android version and your experience. The table below compares the pros and cons of each:

For most modern devices (2020 and newer), the optimal choice is Magisk. It allows you to hide root from applications, supports modules to expand functionality and is regularly updated. SuperSU is outdated, and One-Click solutions often contain advertising or viruses.

Step-by-step guide: how to install Magisk

This method is suitable for most devices with an unlocked bootloader. If you have Samsung, Google Pixel or Huawei - look for separate guides for these brands.

Step 1. Download the necessary files:

• 📱 Latest version of Magisk (file Magisk-v26.4.zip).
• 💻 ADB and Fastboot for PC.
• 📄 Firmware for your model (if you need to patch boot.img).

Step 2. Patching boot.img:

1. Download the original file boot.img for your firmware (can be extracted from the factory firmware or downloaded from 4PDA).
2. Move boot.img i Magisk-v26.4.zip to your phone.
3. Install Magisk APK as a normal application (allow installation from unknown sources).
4. Open Magisk, click Install → Select and patch the file and specify boot.img.
5. After patching, a new file magisk_patched.img will appear in the folder Download.

Step 3. Installation via fastboot:

1. Connect the phone to the PC and reboot into fastboot:

   adb reboot bootloader

2. Flash the patched boot.img:

   fastboot flash boot magisk_patched.img

3. Reboot the phone:

   fastboot reboot

If after reboot Magisk does not appear in the list of applications - install Magisk APK manually. To check the root, use the command in the terminal:

su

If the superuser prompt appears, everything was successful.

Solving typical problems after receiving root

Even if everything went smoothly, problems may arise. Here are the most common ones and how to fix them:

• 🔄 The phone does not turn on or is stuck on the logo:
  • Reflash the original one boot.img via fastboot.
  • If that doesn’t help, do a full reset via TWRP or fastboot (fastboot -w).
• 🚫 Banking applications do not work:
  • Enable in Magisk options MagiskHide (or Zygisk + DenyList in new versions).
  • Install modules Universal SafetyNet Fix and MagiskHide Props Config.
  • Check progress SafetyNet through the app YASNAC.
• 📱 OTA updates do not arrive:
  • Install the module Magisk Delta for OTA support.
  • Or download updates manually and flash them via TWRP.
• 🔋 Battery drains quickly:
  • Check active modules in Magisk —some may waste power.
  • Disable MagiskHideif you do not use banking applications.

If, after installing the root, NFC, Wi-Fi or mobile network stopped working, most likely the problem is the incompatibility of the custom kernel or module. Try:

1. Remove all installed modules in Magisk.
2. Flash the original kernel (boot.img).
3. Use alternative assemblies Magisk (for example, Magisk Alpha).

⚠️ Attention: On devices with Dynamic Partition (Android 10+), the wrong firmware boot.img can lead to data loss in the system or vendorpartitions. Always check file compatibility before. firmware.

How to remove root access and return the phone to its original state

If you decide to give up root (for example, to sell a phone or use banking services), there are two ways:

Method 1. Through Magisk (soft reset):

1. Open the application Magisk.
2. Go to Settings → Complete removal.
3. Confirm the action and restart the phone.

This method removes Magiskbut leaves the bootloader unlocked for some applications (for example, Netflix or Pokémon GO) this is enough to get them working again.

Method 2. Full reset via firmware (hard reset):

1. Download original firmware for your model from the manufacturer's official website or 4PDA.
2. Flash it via fastboot or Odin (for Samsung):

   fastboot flash boot boot.img
   fastboot flash system system.img
   fastboot flash vendor vendor.img
   fastboot -w

3. Lock the bootloader back (optional, but recommended for warranty):

On devices with It is impossible to lock Samsung Knox bootloader back - the Knox 0x1 flag remains forever. This does not prevent you from using the phone, but does not allow access to some functions (for example, Samsung Pay).
