Owners of the line Samsung Galaxy Note often face limitations of the standard One UI firmware, which blocks access to system functions. obtaining root access superuser (Root) opens up opportunities for deep customization, removing built-in software and increasing device performance. However, this process requires strict adherence to the sequence of actions, since incorrect intervention can lead to serious software failures.
In this article we will look in detail at how to safely obtain Root access on smartphones of the series Noteusing a modern tool Magisk and the official Software Odin. We will consider the stages from unlocking the bootloader to the final setting of access rights, paying special attention to the specifics of working with devices of the Korean giant.
It should be immediately noted that the procedure for obtaining root access irreversibly changes the state of some service memory sections. This affects the operation of banking applications and proprietary security services, such as Samsung Knox. Be prepared for the fact that some functions, for example Samsung Pay or the protected folder, may stop working even after returning to factory settings.
Device preparation and backup
Before starting any manipulations with the system partition, it is critically important to save all personal data. The process of unlocking the bootloader and flashing it often leads to complete removal of information from the internal memory. Back up your contacts, photos and documents to cloud storage or to your computer.
Make sure your battery charge Samsung Galaxy Note is at least 60%. Interrupting the firmware process due to a low battery may result in the device turning into a brick. You will also need a high-quality original USB cable, since cheap analogues can cause failures when transferring large amounts of data.
⚠️ Attention: Unlocking the bootloader on Samsung devices irrevocably trips the physical fuse Knox. The counter value will change from 0x0 to 0x1, and this cannot be rolled back programmatically.
Developer mode must be activated to access debugging. Go to the menu Settings → Phone information → Software information and quickly click 7 times on the item Build number. After the message “Developer mode is enabled” appears, go to the menu that appears in the main settings and activate the switch USB debugging.
☑️ Preparing for firmware
Unlocking the bootloader
The first step towards getting Root is to unlock the bootloader. On modern models of the series Note this procedure requires confirmation through special key combinations. Turn off the smartphone completely, then press the Volume Down and Powerbuttons at the same time, holding them until the warning screen appears.
Press the button Volume Up to continue and enter Download Mode. Here you will need to hold the button for a long time Volume Up to unlock. The device will warn you about risks and data deletion - confirm the action. After this, the phone will reboot and perform a factory reset.
After the first boot, you will need to set up the language and Wi-Fi again. Return to Developer Mode and make sure that the item OEM unlock is now active and toggleable (it may be grayed out but enabled by default after the first reset). Without this item, further actions are impossible.
If the OEM unlock item is missing or inactive, wait 7 days with an Internet connection. This is Samsung's protection against device theft.
It is important to understand the difference between software and hardware locking. In some regions or firmware versions for telecom operators, bootloader unlocking may be completely prohibited at level CSC (region code). In this case, obtaining root access using standard methods is impossible without replacing the region identifier.
Installing custom TWRP recovery
To install superuser rights, we will need a custom recovery menu. Standard Recovery from Samsung does not allow flashing unsigned images. We will need the latest version TWRPadapted specifically for your model Galaxy Note.
Download the image file .tar or .img from a trusted resource, for example, the XDA Developers forum. Connect your phone to your PC in Download Mode. Run the app Odin on your computer and make sure that the port in the field ID:COM is highlighted in blue or yellow.
In the interface Odin click the button AP and select the downloaded TWRP file. A critically important point: in the settings Odin (Options tab) you need to uncheck the item Auto Reboot. If this is not done, the standard recovery will overwrite TWRP immediately after the first reboot.
| Button in Odin | File type | Purpose |
|---|---|---|
BL |
Bootloader | System bootloader |
AP |
System/Recovery | System or Recovery |
CP |
Modem | Radio module and network |
CSC |
Consumer Software | Regional settings |
After pressing the button Start wait for the message PASS! in the green field. Immediately, as soon as the progress bar disappears, force reboot the device into TWRP mode by holding down the combination Volume Down + Power. As soon as the screen goes dark, quickly release Volume Down and hold Volume Topwithout releasing Power.
⚠️ Attention: If you accidentally booted into stock Android, TWRP will be overwritten. You will have to repeat the flashing procedure via Odin again.
What to do if TWRP does not start?
If the recovery menu does not appear, try clearing the Dalvik/Cache partition inside Download Mode before flashing again. Also make sure that you are using a version of TWRP that is compatible with your version of Android (Android 10, 11 or 12 require different builds).
Magisk firmware to get Root
The modern standard for obtaining superuser rights is Magisk. Unlike the outdated SuperSU, it uses a systemless modification method, which allows you to hide the presence of Root from some applications. Download the current Magisk APK file and rename its extension to .zip (if you are flashing via TWRP) or leave .apk (if you are patching the image).
After booting into TWRP, go to the Installsection. Locate the Magisk firmware file on your internal memory or memory card. Swipe to confirm installation. The process will take a few seconds, after which a message indicating successful completion will appear.
An alternative and more reliable method is patching the image boot.img. Extract the file boot.img from the official firmware of your model. Transfer it to your phone, open the Magisk application, press Install and select Boot image patch. The resulting file magisk_patched.img return to the PC and flash it via Odin in the field AP.
- 🔹 Systemless Root —does not modify the system partition, which simplifies OTA updates.
- 🔹 Magisk Hide —allows you to hide rights from banking applications and games.
- 🔹 Modules — support for plugins for changing fonts, sounds and system parameters.
After installation, restart your smartphone in normal mode. If the Magisk icon appears in the list of applications, and at startup you are asked to grant superuser rights - congratulations, the procedure is successful. Now you can control access to the system kernel.
Setting up rights and working with modules
Gaining access is only half the battle. For stable operation, it is necessary to correctly configure the rules for granting privileges. The first time you launch any application that requires Root, Magisk will ask for confirmation. Do not grant rights to dubious apps unnecessarily.
It is recommended to enable the function in the settings of the Magisk application itself Zygisk. This is a new code injection technology that is more stable than older methods. Also activate the item Follow the list of exceptionsto add banking applications to the black list of modifications.
Using modules you can expand the functionality Galaxy Note. For example, the module LSPosed allows you to implement tweaks into the One UI interface, changing the behavior of the notification panel or navigation gestures. However, installing a large number of modules may reduce the performance of the device.
Check for Magisk kernel updates regularly. Developers often release patches that fix vulnerabilities or improve compatibility with new versions of Android. The update is similar to the initial installation: through the app menu or flashing the patched image.
The use of Zygisk and the exclusion list (DenyList) is mandatory for running banking applications on a rooted device.
Possible problems and ways to solve them
In the process of modifying the system, users may encounter a number of typical problems errors. The most common is a cyclic reboot (bootloop). If the phone does not boot beyond the Samsung logo, you need to go into TWRP and reset the data (Wipe Data/Factory Reset), and then clear the cache Dalvik.
Another problem is the lack of Internet access after the firmware. This may be due to radio module incompatibility. In this case, flashing the file CP (modem) from your firmware version via Odin helps. Never use a modem from a different model or region.
If banking applications still detect Root despite the hide settings, try changing the name of the Magisk package in the application settings before installation. Also make sure that all components of Google Play Services and the banking application itself are checked in the list of hidden processes.
⚠️ Attention: The interfaces of the Odin and Magisk apps may be updated. If the buttons or menu items differ from those described, check with the official documentation of the developers, since the operating logic remains the same, but the visual design changes.
Frequently asked questions (FAQ)
Will Knox work after receiving Root?
No, the Knox physical fuse triggers when the bootloader is unlocked. This is an irreversible process. Services that depend on Knox (Secure Folder, Samsung Pay) will not work even if you remove root access.
Is it possible to get OTA system updates with Root?
Official over-the-air (OTA) updates are usually not installed on modified devices. You will have to download the full firmware manually and update via Odin, while maintaining the data (unless you change the region).
Is it safe to use banking applications?
When Magisk Hide (or DenyList) and Zygisk are configured correctly, most banking applications work correctly. However, some banks use advanced detection methods, and access may be blocked.
What to do if the phone went into Bootloop?
Go into Recovery mode (TWRP), execute Wipe -> Dalvik/Cache. If that doesn't help, do a full reset Factory Reset. As a last resort, reflash the stock firmware via Odin in Download Mode.
Do you need to reflash the phone when changing the region?
Yes, for correct operation of all functions and receiving updates, it is recommended to flash the complete set of files (BL, AP, CP, CSC) corresponding to the region code of your device or the desired region.
