Cistemnaya folder Data v Android 11 stores critical information: application settings, cache, databases and user files. Odnako Google uzhestochila ogranicheniya na dostup k etomu razdelu, motiviruya eto zashchitoy konfidentsialnosti. Esli vam nuzhno vosstanovit udalennye dannye, perenesti nastroyki mezhdu ustroystvami ili vruchnuyu redaktirovat konfiguratsionnye fayly — standartnye metody ne srabotayut.

V etoy state my razberyom 5 legal ways to access the Data folder on Android 11 without losing your warranty, vklyuchaya ispolzovanie ADB, storonnikh faylovykh menedzherov i skrytykh rezhimov developer. Vazhno: vse metody trebuyut ostorozhnosti — nepravilnye deystviya mogut privesti k app crashes ili dazhe data loss. We will indicate the risks for each option and give recommendations for backup.

Why does Android 11 block access to the Data folder?

Nachinaya s Android 10, Google vnedrila kontseptsiyu Scoped Storage — izolirovannogo khranilishcha, gde kazhdoe prilozhenie rabotaet v svoey "pesochnitse". V Android 11 ogranicheniya uzhestochilis eshchyo silnee:

  • 🔒 Zapret na dostup k chuzhim dannym: Prilozheniya ne mogut chitat fayly drugikh programm bez yavnogo razresheniya.
  • 📁 Hidden system paths: Papki /data/data/ i /data/app/ became invisible to the user.
  • 🛡️ Default security: Even with rights root additional configuration is required SELinux.

These changes are aimed at combating malware, but create problems for experienced users. Naprimer, nevozmozhno vruchnuyu:

  • 🔄 Perenesti sokhraneniya igr mezhdu ustroystvami.
  • 📝 Otredaktirovat konfiguratsionnye fayly prilozheniy (naprimer, shared_prefs).
  • 🗑️ Vosstanovit udalennye SMS ili zhurnal zvonkov cherez /data/com.android.providers.telephony/.
⚠️ Vnimanie: An attempt to access /data/ on devices with locked bootloader (for example, Samsung Knox or Xiaomi with MIUI) may result in protection triggered and automatic factory reset.

Method 1: Using ADB (without root access)

The most universal method is connecting via Android Debug Bridge (ADB)It works on most devices, but it requires. turning on USB debugging and computer.

Steps to access:

  1. Activate Developer mode:
    • Go to Settings → About phone → Build number.
    • Press 7 times in a row until the "You have become a developer" notification appears.
  • Enable USB Debugging in Settings → System → For Developers.
  • Connect your phone to the PC and confirm the trusted device.
  • Open the command line (Windows) or terminal (macOS/Linux) and enter: 
    adb shell

    su -c "setenforce 0" # Disables SELinux (requires root access, if any)
    

    ls /data/data/ # View folder contents

    • If you have no root, use an alternative command to copy files:

    adb pull /data/data/com.example.app/ ./backup/
    ⚠️ Attention: The command setenforce 0 temporarily disables protection SELinux, which can make the system vulnerable. Always return the value 1 after completion of work:

    su -c "setenforce 1"

    Method 2: File managers with root support

    If your device has unlocked bootloader rights superuser, use specialized explorers:

    Application Requires root? Features Link (Play Market)
    Root Explorer ✅ Yes Full access to /data/, built-in text editor Download
    FX File Explorer ✅ Yes Support ADB and SFTP, cloud storage Download
    Solid Explorer ❌ No (partial access) Can view some system folders without root Download

    Instructions for Root Explorer:

    1. Open the application and grant permissions superuser.
    2. Go to the root directory (/).
    3. Find the folder data → data → select the desired application (for example, com.whatsapp).
    4. Copy or edit files (for example databases/msgstore.db for WhatsApp).
    💡

    Before editing system files, create a backup copy of them in the cloud or on a PC. For example, for a database Telegram copy the folder /data/data/org.telegram.messenger/databases/ entirely.

    Method 3: Backup via TWRP

    If custom recovery is installed on your device custom recovery TWRP, you can create a full backup of the partition /data:

    Step-by-step guide:

    1. Turn off the phone and boot into TWRP (usually Power + Volume Up).
    2. Go to section Backup.
    3. Select section Data (not to be confused with Internal Storage!).
    4. Start the copying process. File backup will be saved on the memory card (.tar or .win).
    5. Connect the card to the PC and extract the necessary files from the archive using 7-Zip or WinRAR.
      6. ⚠️ Attention: Backup via TWRP can take up to 30 minutes and requires at least 50% battery charge. Interrupting the process will lead to data loss.
      How to extract a specific file from a TWRP backup?

      1. data-i="148">in 7-Zip. data.win001 in 7-Zip.

      2. Go to the folder /data/data/com.package.name/.

      3. Find the file you need (for example, shared_prefs/app_settings.xml).

      4. Extract it to a separate folder.

      5. To restore, copy the file back via ADB or Root Explorer.

      Method 4: Using applications for backup

      Some apps can create backups of application data without root access, using Android Backup ServiceThe best options:

      • 📦 Swift Backup (requires adb backup or root).
      • 🔄 Titanium Backup (only for root).
      • ☁️ OAndBackupX (free, works via ADB).

    Example with OAndBackupX:

    1. Install the application and connect the phone to PC.
    2. In the terminal, do: 
      adb backup -f backup.ab com.example.app

      (replace com.example.app with the package of the desired application).

    3. On your phone, confirm the creation of a backup (do not set a password!).
    4. The file backup.ab will appear on the PC. Unpack it using abe (Android Backup Extractor): 
      java -jar abe.jar unpack backup.ab backup.tar

    Method limitations:

    • ❌ Not all applications support adb backup (for example, Facebook or Banking applications block this function).
    • ❌ Critical files may be missing in the backup (for example, lib/ or cache/).

    Method 5: Manually mounting the partition (for advanced)

    This method is suitable for devices with unlocked bootloader and requires knowledge of commands LinuxWe. mount the partition /data on the PC via ADB:

    Instructions:

    1. Connect the phone in mode ADB and do: 
      adb shell

      su
      

      mount -o rw,remount /data

    2. Copy the necessary files to your PC: 
      adb pull /data/data/com.example.app/ ./app_data/
    3. To edit system files (for example, build.prop) use: 
      adb shell

      su
      

      mount -o rw,remount /system
      

      nano /system/build.prop

    ⚠️ Attention: Incorrect mounting can lead to the cyclic reboot device. If after the commands the phone does not turn on, perform a reset via Fastboot:

    fastboot erase userdata

    fastboot reboot

    💡

    Mounting the partition /data in rw (read-write) mode temporarily disables protection. Always return the mount to ro (read-only) mode after completing work.

    Common errors and how to avoid them

    When working with a folder Data users encounter typical problems:

    Error Cause Solution
    Permission denied Insufficient rights or enabled SELinux Run su -c "setenforce 0" or get root
    Device not authorized Not USB debugging confirmed Reconnect the device and allow access on the phone screen
    Folder /data/ empty Device with dynamic partition (for example, Pixel 4) Use ls /data/media/0/ to view user data

    Additional tips:

    • 🔌 If ADB does not see the device, update the drivers via SDK Platform Tools.
    • 🔄 On some devices (Huawei, Xiaomi), you need to disable MIUI Optimization in the developer settings.
    • 📱 For Samsung s Knox use Odion or Heimdall instead of the standard ADB.
    Can I access the Data folder without root and a computer?

    Partially - yes. Some file managers (for example, FX Explorercan show system folders through the built-in ADB server, but for full operation you will still need to connect to a PC for authorization.

    Without a computer you will be able to view only those files that are not protected SELinux (usually cache and temporary data).

    How to find the batch name of an application to access its data?

    Use the command:

    adb shell pm list packages | grep "keyword"

    Replace keyword with part application name (for example whatsapp). To view all installed packages, remove | grep "keyword".

    Will Knox or blocking work on Xiaomi when accessing Data?

    Yes, on devices with Knox (Samsung) or MIUI (Xiaomi/Redmi/Poco) any attempt to change system files can lead to:

    • Flag activation Knox 0x1 (loss of warranty and Samsung Pay).
    • Loader lock on Xiaomi (requires unlocking via Mi Unlock Tool).

    Before experiments, check the blocking status with the command:

    adb shell getprop ro.boot.veritymode

    If the value is enforcing the protection is active.

    How to recover deleted files from the Data folder?

    If the files were recently deleted, try:

    1. Create a full backup of the partition /data via TWRP.
    2. Use utilities like Scalpel or Foremost to restore from an image: 
      scalpel -o output_dir/ backup.img
    3. For databases (.db files) try SQLite Database Browser.

    The chances of recovery depend on whether the data was overwritten. On F2FS (the file system of many modern Androids) recovery is more difficult than on ext4.

    Are these methods legal?

    The methods themselves are legal if you work with his device. However: Google may block access to services (for example,

    • Google may block access to services (for example, Google Payif it detects changes in system files). (especially build.prop).
    • On devices with SafetyNet (for example, for Netflix or Pokémon GO) protection is triggered when the bootloader is unlocked.
    • Changing banking application files or DRM-protected content (Netflix, Widevine) can lead to account blocking.

    To check the status SafetyNetuse the application SafetyNet Test.
