With the release Android 13 Google has significantly tightened its security policy, limiting access to critical system systems directories, including the folder /data/data. Previously, users could view the contents of applications relatively easily through file managers or the computer, but now standard methods Android Debug Bridge (ADB) without root access block reading this area. This change is aimed at protecting personal data from malware and unauthorized copying, but creates difficulties for advanced users who need access to databases or cache files. Unlocking a folder on modern versions of the operating system requires not only enabling USB debugging, but also understanding the permissions architecture. If you try to run a command
Unlocking a folder Data on modern versions of the operating system, it requires not only enabling USB debugging, but also understanding the permission architecture Selinux. If you are trying to run the command adb pull /data/data on stock firmware, the system will return a "Permission denied" error. To bypass these restrictions, there are various approaches: from obtaining root access to using specialized utilities like Shizukuthat work in privileged mode without completely flashing the device.
In this guide we will examine in detail the technical aspects of accessing protected memory sections. We will look at both legal methods of working with the file system via a computer, and radical ways to gain complete control over the device. Remember that any manipulation of system files carries risks, so before starting work you need to create a complete backup of important information.
Why Android 13 blocks access to the Data folder
The main reason for the inability to view the contents of the directory /data/data is the application isolation mechanism known as Sandboxing. B Android 13 this mechanism has been strengthened at the kernel and security policy level. Each application runs in its own space with a unique user identifier (UID), and by default, processes do not have rights to read data from other applications or system services. Selinux. Each application runs in its own space with a unique user identifier (UID), and by default, processes do not have rights to read data from other applications or system services.
⚠️ Warning: Attempting to force chmod changes to system folders without understanding the file structure may result in a device bootloop or data loss.
Google also limited the capabilities of the protocol ADB in read-only mode. Even if you connect your smartphone to the PC and enable debugging, the daemon adbd runs with limited user privileges shellwho does not have rights to bypass restrictions Selinux. This means that standard commands for copying files from protected areas will simply not be executed by the system.
In addition, the latest security updates have closed a vulnerability that allowed some file managers to bypass these restrictions through special URIs or temporary permissions. Now access to /data is possible only for processes running with rights root (superuser) or through special system services with elevated privileges.
Preparing the device and enabling debugging
The first step towards gaining access is to correctly configure the smartphone itself. You need to activate the hidden developer menu, which is disabled by default for the safety of the average user. Without this step, any attempts to connect to a computer to send commands will be unsuccessful.
Go to the settings of your device and go to the About phonesection. Find the item Build number and quickly click on it 7 times in a row. The system will notify you that you have become a developer. After this, a new section will appear in the main settings menu For developerswhere you need to find and activate the switch USB debugging.
When After connecting the cable to the computer, a request for permission to debug from this PC will appear on the smartphone screen. Be sure to check the box "Always allow from this computer" and confirm the action. This will create a trusted connection between devices, necessary for working with ADB.
☑️ Checking the readiness of the device
To work, you will also need to install the package Platform-tools on your computer. This is a set of utilities from Google, including adb and fastboot. After unpacking the archive, open the command line in the folder with the utilities and enter the command adb devices. If everything is configured correctly, you will see the serial number of your device in the list.
Method of obtaining root access through Magisk
The most reliable and complete way to unlock a folder /data is to obtain superuser rights. The tool Magisk allows you to do this in a system-seamless way, without violating the integrity of the system partition /system, which is important for the operation of banking applications and Google Pay services (although in Android 13 root access is becoming increasingly difficult).
The process begins with unlocking the bootloader (Bootloader). Device manufacturers implement this procedure in different ways: for Xiaomi a special utility and waiting a week is required, for Pixel and Motorola the command fastboot flashing unlockis sufficient. Remember that this operation will completely delete all data from the device, performing a factory reset.

fastboot flashing unlock
After unlocking the bootloader, you need to flash a modified image boot.imgcontaining patches Magisk. First, extract the image from the official firmware of your model, then open the Magisk application on your phone, select "Install" -> "Select and patch file", specify the extracted image. The resulting file magisk_patched.img needs to be flashed through a computer in Fastboot mode.
⚠️ Attention: Unlocking the bootloader and obtaining root access will void the warranty on the device. Some applications (banks, games with anti-cheat) may refuse to work on rooted smartphones.
After successful installation and loading of the system, you will have full access to the file system. You will be able to use root-enabled file managers such as Root Explorer or Mixplorerto view and edit the contents of the folder /data/data. ADB commands will now be executed with superuser privileges after entering adb shell and subsequent su.
Risks of using Magisk
Although Magisk tries to hide the fact of obtaining root access (MagiskHide/Zygisk), some applications have learned to bypass this protection. In addition, errors when flashing the boot image can cause the phone to stop booting, requiring recovery via EDL mode or flashing the stock image.
Using Shizuku for access without Root
For users who do not want to unlock the bootloader or risk the warranty, there is an alternative solution - the application Shizuku. This service allows ordinary applications to use system APIs with elevated privileges, using the mechanism ADBbut running directly on the device.
Unlike standard ADB, which works through a cable, Shizuku runs a service that has user rights shell with advanced capabilities. Although it does not give full access to all files in /data/data (since Selinux limitations remain), it allows many tools (for example Titanium Backup in limited mode or specialized managers) to perform actions previously only available with root.
To activate Shizuku on Android 13 without a computer (on some devices) you can use wireless debugging. Go to the developer menu, turn on "Debugging over Wi-Fi", click "Use pairing code". In the Shizuku app, select "Run via wireless debugging", enter the code and port. The service will start and work until the device is rebooted.
| Access method | Root required | Access to /data/data | Difficulty | Security |
|---|---|---|---|---|
| Standard ADB | No | Forbidden | Low | High |
| Shizuku | No | Partial | Average | High |
| Magisk (Root) | Yes | Full | High | Medium |
| Custom Recovery | Yes (temporary) | Full | High | Low |
It is important to understand that Shizuku is not an analogue of root access in the full sense. It can't modify system files or bypass all security checks, but for backing up user application data its capabilities are often sufficient.
Working with file managers and ADB commands
If you've rooted or configured Shizuku, the next step is to choose the right file management tool. Standard Android Explorer will not see changes in permissions. You will need specialized applications, such as MT Manager, Root Explorer or Solid Explorer with the root access plugin enabled.
When working through a computer and ADBafter gaining superuser rights in the console, you can use commands to extract data. First, log into the shell:
adb shell
su
After the symbol appears # instead $ you have full rights. Now you can copy the desired folder to temporary storage, accessible for reading, and then take it to your PC. For example:
cp -r /data/data/com.example.app /sdcard/backup_appexit
adb pull /sdcard/backup_app
⚠️ Warning: When copying databases of running applications (for example, SQLite), the files may be damaged if the application is actively writing data to them at the time of copying. It is recommended to force stop the application before extracting files.
Some file managers allow you to mount the file system in read-write mode directly. This is convenient for quickly editing configs, but extremely dangerous. An error in one byte of the configuration file can render the application inoperable. Always create backup copies before editing.
The safest way to work with files from the Data folder is to copy them to the internal memory (/sdcard), edit them on the PC and replace them, rather than directly edit them on the system partition.
Possible problems and solutions
Even with root access, users Android 13 may encounter a "Read-only file system" error when trying to write to a folder /data. This is because modern file systems (often F2FS or ext4) are mounted read-only by default after boot. To change this status, the partition must be remounted.
Use the command mount with the remount flags. In a root terminal, enter:
mount -o rw,remount /dataAnother common problem is data encryption. Android 13 uses file-level encryption (FBE). If the device is not unlocked (the screen is turned off or is on the PIN entry screen), the folder /data/data is physically unreadable even with root access, since the decryption keys have not yet been loaded into memory. Access appears only after the user successfully enters the password for the first time after switching on.
- 📱 Make sure the screen is unlocked before attempting to access data.
- 🔐 Check if additional folder encryption is enabled through the security settings.
- 🔄 Reboot the device if the file manager gives access errors after getting root.
- 🛡️ Disable anti-virus scanners that may block access to system files.
It is also worth considering that some manufacturers (for example, Huawei or Honor on new models) have completely closed the ability to unlock the bootloader. On such devices, gaining access to the folder /data by legal methods is almost impossible without using vulnerabilities (exploits), which is unstable and dangerous.
Frequently asked questions (FAQ)
Is it possible to unlock the Data folder on Android 13 without losing data?
Obtaining root access by unlocking the bootloader always implies a complete data reset (Wipe Data). However, using the method Shizuku or vulnerabilities (if they exist for a specific model) allows you to get expanded access without formatting, but the functionality will be limited compared to full Root.
Why does the adb pull /data/data command give a Permission denied error?
This is standard behavior in Android 13. The ADB daemon runs with user rights shell, which does not have rights to read other people's data for security reasons. To bypass, you need to either get root access on the device and use the command su inside the shell, or use specialized backup tools.
Is it safe to edit files in the /data/data folder?
No, this action is associated with a high risk. Changing access rights (chmod/chown) or editing critical databases can lead to unstable system operation, application crashes, or the inability to boot the OS. Always make a backup before making changes.
Does this method work on all smartphones with Android 13?
The security logic is the same for the entire Android platform, but methods for obtaining root access is highly dependent on the manufacturer. On devices with a locked bootloader (some Xiaomi, Huawei, American versions of Samsung), standard Magisk firmware methods will not work.
How to get everything back if something went wrong?
If you have changed access rights to system folders, the best solution is to reset to factory settings (Factory Reset) through the Recovery menu. This will return the original Selinux rights and permissions. If the device does not boot, you will need to flash the stock image via Fastboot or Odin.
