Modern smartphones Samsung have powerful hardware and rich functionality, but the built-in limitations of the operating system Android often prevent them from unlocking their full potential. Many advanced users seek to obtain root accessto remove system junk, install specialized modules or completely customize the device interface.
The process of obtaining superuser on devices of the Korean giant has become significantly more complicated in recent years. If previously there were “one-click” solutions, now the user has to go through unlocking the bootloader, installing custom recovery and patching system images. This requires care and understanding of the architecture One UI.
In this material we will analyze in detail the current rooting method, which is suitable for most models released after 2019. You will learn how to prepare the device, what tools to download and how to avoid turning your smartphone into a “brick.”
Preparation of the device and risk assessment
Before you start modifying the system partition, you need to understand all the consequences of interfering with the work bootloader. The company Samsung has implemented reliable protection Knoxthat physically reacts to any unauthorized access attempts.
As soon as you unlock the bootloader, a special electronic fuse (e-fuse) will work. This action is irreversible and will permanently reset the counter. Knox Warranty Bit.
⚠️ Attention: Once the Knox trigger is triggered, the device's warranty will be voided, and features such as Samsung Pay, Secure Folder, and some banking apps will stop working permanently, even if you return to stock firmware.
You will need to create a full backup a copy of all personal data, since the process of unlocking the bootloader involves full data reset (Factory Reset). Also make sure that the battery charge is at least 60-70% to avoid a power outage at a critical moment.
To work, you will need an original USB cable and a computer running Windows. Drivers Samsung USB Driver must be installed correctly in the system, otherwise the firmware tools will not see the smartphone in mode Download Mode.
Save important information from a secure folder (Secure Folder) to a cloud server or external storage device before starting work, as access to it will be lost irrevocably.
Unlocking the bootloader (Bootloader)
The first and mandatory step is to unlock the bootloader. On newer models, this option is hidden in the developer menu. Go to Settings → About phone → Software information and quickly click 7 times on the item Build number.
After activating the developer menu, go to the new section in the main settings. Here you need to find the item OEM unlocking and move the switch to the active position. If this item is not present, the device may be locked to an operator or the firmware region does not support this function.
Next, you need to switch the smartphone to a special mode. Turn off the device completely. Then press the Volume Down and Power buttons simultaneously and hold them until the warning screen appears. After that, release the buttons and press Volume Up once to confirm unlocking.
⚠️ Attention: The warning screen may be in English. Look for a line that mentions "Device custom binaries" or "OEM unlock". Confirming the action will clear all user data.
The reset process will take several minutes. After rebooting, you will see a notification that the bootloader is unlocked. Now the device is ready to accept custom images through the mode. data-i="79">Didn’t try to unlock Download Mode.
Installing custom TWRP recovery
Standard recovery menu Samsung does not allow installing third-party ZIP archives or making full system backups. For these purposes it is used TWRP Recovery. You need to find the exact version of the recovery designed specifically for your model (device code name, for example, SM-G991B).
Download the image file twrp.img and move it to the folder with the installed platform Odin. Boot the phone into mode Download Mode (by holding Volume Up, Volume Down and connecting the cable to the PC).In the Odin app, the recovery file must be written to the slot AP.
Critical point: after flashing TWRP, you should not allow the system to boot in normal mode. Immediately after the process is completed, you must perform a special procedure in Odin. combination of buttons to enter recovery.
Hold Volume Up + Power (hold until the TWRP logo appears)If you make a mistake and the phone boots into a normal system, the stock recovery Samsung will automatically overwrite TWRP, and you will have to repeat the procedure firmware again. In the TWRP menu, immediately swipe to allow modifications.
Why does TWRP crash after the first boot?
The stock Android system checks the integrity of the recovery partition when loading. If a signed TWRP image is detected, the system replaces it with the original one. Logging into TWRP immediately after flashing it prevents this. process.
The process of obtaining superuser rights through Magisk
The most reliable and modern method of obtaining Root-right is to use the utility Magisk. It works on the systemless principle, that is, it does not make direct changes to the system partition, which increases stability and allows you to hide the fact. rooting from some applications.
You will need the original firmware file that is currently installed on your device. You can download it from specialized resources (for example, SamMobile or Frija). From the archive with the firmware you need to extract the file starting with AP_.
Copy this file to your smartphone Install. application Magisk Manager (APK file). Open the application, click on the button Install next to Magisk and select the option Select and patch the file. Specify the previously copied file AP_....
After the process is completed, a new file with the name type Download a new file will appear with the name view magisk_patched_[random].tar. This file must be transferred back to the computer and flashed through Odin into the slot AP, after removing the checkmarks from the items Auto Reboot i F. Reset Time.
| Odin slot | Firmware file | Purpose |
|---|---|---|
BL |
Bootloader | System bootloader |
AP |
magisk_patched.tar | System with root access |
CP |
Modem | Radio module and communication |
CSC |
Consumer Software Customization | Regional settings and data |
After flashing the patched file, perform a forced reboot (by holding Volume Down and Power for 7 seconds), and then immediately enter the mode Recovery so that the system does not erase the changes. A successful boot with the Magisk application running means that superuser rights activated.
☑️ Checklist for successful Root installation
Checking operation and hiding root access
After the first launch, open the application MagiskIf at the top of the screen you see the version of the installed utility and the status. “Installed” means the procedure was successful. To check, you can use specialized utilities, for example Root Checker from the application store.
However, having root access often blocks the operation of banking applications and contactless payment services. To bypass this limitation, you need to activate the function Zygisk in the Magisk settings and enable the list of exceptions. (DenyList).
Add all banking applications, Google Pay (Wallet) and Google Play services to this list. This will force Magisk to hide the presence of superuser rights for these apps. In some cases, you may need to install an additional module. Universal SafetyNet Fix.
⚠️ Attention: Dazhe so skrytymi pravami nekotorye bankovskie prilozheniya mogut opredelyat razblokirovannyy zagruzchik. In such cases, working with them may not be possible using any software methods.
Regularly update the Magisk application and modules, as methods for detecting rooting by banks are constantly being improved. Keep an eye on thematic forums for your specific model.
Hide Root from banks is possible through the Magisk settings (Zygisk + DenyList), but it is impossible to hide the unlocked bootloader (Knox 0x1), which limits the operation of Samsung Pay.
Possible problems and ways to solve them
In progress Rooting may cause various errors. One of the most common problems is the “bootlap” (endless reboot). If the phone is stuck on the logo Samsung, try entering Recovery mode (TWRP) and wipe the cache (Wipe Cache/Dalvik).
If TWRP does not start or the phone immediately reboots into the system, you may be using the wrong version of recovery for your device revision. Make sure to download the file for the correct processor (Exynos or Snapdragon) and region.
Another common error is the "Secure Check Fail" message when flashing firmware via Odin. This means that you are trying to flash a file from a different model or version of Android. Always check the revision bits (Binary Version) before flashing the firmware.
In case of failure, you can always return to the factory state. Download the full stock firmware (4 files: BL, AP, CP, CSC) and flash it via Odin. This will remove root access and return the guarantee at the software level, although the physical Knox trigger will remain triggered.
What to do if Odin hangs at the SetupConnection stage?
Reboot the phone in Download Mode, reconnect the USB cable to another port (preferably USB 2.0 on the back of the PC) and restart Odin ot imeni administratora.
FAQ: Chastye voprosy po rutirovaniyu Samsung
Mozhno li poluchit Root na Samsung bez razblokirovki zagruzchika?
Net, na sovremennykh ustroystvakh Samsung eto nevozmozhno. Unlocking the bootloader is a prerequisite for installing a custom recovery and modifying the system partition. Any applications that promise root without PC and unlocking do not work on new models.
Will Knox work when using only Magisk without TWRP?
Yes, it will work. The physical fuse reacts to a change in the bootloader unlock flag (OEM Unlock), and not to the fact that TWRP or Magisk is installed. As soon as you allowed unlocking in the settings, the Knox counter went to state 0x1.
Will I receive OTA updates after rooting?
Automatic over-the-air (OTA) updates will not work because the system partition has been modified. When you try to update, you will receive an error. To update the system, you will have to manually download the firmware and flash it through Odin, which will again require patching the AP file through Magisk.
Is it safe to use banking applications with Root?
It depends on the Magisk settings. With the correct configuration (Zygisk, DenyList, hiding modules) most applications work correctly. However, the risk of account blocking by the bank (as suspicious activity) theoretically exists, although in practice it is rare.
