Viewing system files Android from a computer is a task that requires caution and technical training. These files store critical data for the operation of the operating system: from kernel configurations to application settings. Access to them may be needed for debugging, modifying the firmware or restoring deleted data, but incorrect actions can lead to device inoperability.

Unlike user files (photos, videos, documents), system data is hidden from the user's eyes by default. Manufacturers limit access to them to prevent accidental damage. However, with the help of a computer, special tools and knowledge, these limitations can be overcome. In this article we will analyze 5 proven methods - from safe (through ADB and backups) to advanced (using root access).

It is important to understand: the deeper the access level, the higher risks. For example, changing files in a folder /system without a backup can make the phone “bricked.” Therefore, before any manipulation be sure to create a full backup of your data and make sure that the battery charge exceeds 50%.

Before you start viewing system files, prepare the necessary tools and devices. Without them, further steps will be impossible or unsafe.

You will need:

  • 📱 Android device with an unlocked bootloader (for methods with Root or TWRP).
  • 💻 A computer running Windows, macOS or Linux with installed drivers for your smartphone.
  • 🔌 Cable USB Type-C/Micro-USB (preferably original to avoid problems with connection).
  • 🛠️ Software: ADB i Fastboot, file manager with support Root (for example, Root Explorer), backup utilities.

Also check the following settings on your phone:

  • 🔄 Enable developer mode: go to Settings → About the phone → Build number and tap on it 7 times.
  • 🔧 Activate USB debugging in the developer menu (Settings → System → For developers).
  • 🔒 Allow OEM unlocking (if you plan to work with the bootloader).
⚠️ Attention: Unlocking the bootloader resets the device to factory settings. All data will be deleted. Create a backup copy in advance! data-i="72">📊 Which method of connecting Android to a PC do you use more often?

2. Method 1: Viewing system files via ADB (without Root)

Android Debug Bridge (ADB) is an official tool from Googlethat allows you to interact with the device via the command line. Using it, you can view (but not edit!) some system files without obtaining root access.

This is how it is. works:

  1. Install ADB on your computer (download Platform Tools from the site Google and unpack the archive).
  2. Connect your phone to the PC via USB and confirm permission to debugging on the smartphone screen.
  3. Open the command line (cmd v Windows or Terminal v macOS/Linux) and go to the folder with ADB:
cd path_to_platform-tools_folder
  1. Check the device connection:
adb devices

If the device is displayed in the list, you can start viewing files.

Examples of commands for working with files:

  • 📂 Viewing the contents of a folder /system:
adb shell ls /system
  • 📄 View a text file (for example, build.prop):
adb shell cat /system/build.prop
  • 🔍 Search for files by name:
adb shell find /system -name "file_name"
⚠️ Attention: Commands adb pull and adb push allow you to download and upload files, but changing system data without Root is limited. Some folders (for example, /data) will not be available.

3. Method 2: Using backups (without Root)

If you do not need direct access to files, but only need to view their contents, you can use backups. This method is safer, since it does not require intervention in the system. data-i="109">Methods for creating backups:

Ways to create backups:

  • 📱 Built-in tools Android:
    • Go to Settings → System → Backup.
    • Activate option Backup to Google Drive.
  • 💾 Third-party utilities:
    • Titanium Backup (requires Root).
    • Swift Backup (works without Root on some devices).
    • ADB Backup (via the command adb backup).

To create a backup via ADB:

  1. Connect the phone to the PC and open the command line.
  2. Run the command:
adb backup -f C:\backup.ab -apk -obb -shared -all -system

Where:

  • -apk — backups APK files of applications.
  • -system — includes system applications (required Root on some devices).
  • C:\backup.ab —path to save the backup.

After creating a backup, it can be opened using archivers (for example, 7-Zip) or specialized apps like Android Backup Extractor.

Backup method Root required? What is saved Can I view system files?
Google Disk ❌ No Settings, contacts, some application data ❌ No
ADB Backup ⚠️ Partially Applications, settings, some system data ⚠️ Only some files
Titanium Backup ✅ Yes All applications, system data, settings ✅ Yes
TWRP ✅ Yes Full system image (/system, /data etc.) ✅ Yes
💡

If you need to extract only a specific file (for example, build.prop), use the command adb pull /system/build.prop C:\ —this will save time compared to a full backup.

4. Method 3: Obtaining root access for full access

Root access opens unlimited possibilities for working with system files, but also carries maximum risks. With its help you can:

  • 📂 Edit files in /system, /data, /vendor.
  • 🔧 Remove built-in applications (bloatware).
  • 🔄 Modify system settings (for example, change build.prop to overclock the processor).

How to get Root:

  1. Unlock the bootloader (bootloader) via the command:
fastboot oem unlock
  1. Install custom recovery (TWRP or OrangeFox).
  2. Flash Magisk or SuperSU via TWRP.

After receiving Root you will be able to use file managers like Root Explorer, FX File Explorer or Solid Explorer with support RootThey will allow you to view and edit any files, including:

  • 📄 /system/build.prop - configuration. system.
  • 📄 /system/etc/hosts — hosts file for blocking sites.
  • 📁 /data/app — data of user applications.
⚠️ Attention: Some manufacturers (for example, Samsung c Knox, Huawei) block the warranty when unlocking bootloader. Check your brand's policy before taking action.
What to do if, after receiving Root, the phone stops booting?

If the device goes into a bootloop (cyclic reboot), try:

1. Boot into TWRP and flash the stock kernel.

2. Reset via fastboot erase userdata.

3. Reflash the full stock ROM via Odin (for Samsung) or Fastboot (for other brands).

If all else fails, contact a service center - you may need to resolder the memory.

5. Method 4: Using TWRP to mount system partitions

Team Win Recovery Project (TWRP) is a custom recovery that allows you to mount system partitions and work with them directly. The advantage of the method is that you can view files even if Android does not download.

Instructions for working with TWRP:

  1. Install TWRP on the device (instructions depend on the model, look on the forum XDA Developers).
  2. Boot into recovery mode (usually Power + Volume Up).
  3. In the menu TWRP select Mount → System.
  4. Connect the phone to the PC via USB and select MTP in settings TWRP.
  5. Now system files will be available for viewing on your computer like a regular flash drive.

What can be done through TWRP:

  • 🔍 View and copy files from /system, /vendor, /boot.
  • 📥 Create full backups of partitions (Backup → Select Partitions).
  • 🔧 Restore damaged files from a backup.

Example commands for working with TWRP via ADB:

adb pull /system/app /sdcard/system_app_backup # Copies system applications to the memory card

adb shell "cat /system/build.prop" > build.txt # Saves build.prop to a file on the PC

6. Method 5: Alternative methods (for advanced users)

If standard methods are not suitable, you can use alternative approaches. They require more in-depth knowledge, but sometimes they are the only solution.

Method 1: Extract files via Fastboot

Some devices allow you to read partitions directly via Fastboot:

fastboot getvar all # Shows available partitions

fastboot flash system system.img # Firmware example (not for extraction!)

To extract data, you can use the utility dd:

adb shell

su


dd if=/dev/block/mmcblk0pX of=/sdcard/system.img

Where mmcblk0pX is the system partition (find out its number through ls /dev/block).

Method 2: Firmware analysis (.img files)

If you have a stock one firmware for your model (file .zip or .img), you can unpack it and study the system files:

  • 📦 Use 7-Zip to extract system.img.
  • 🔧 Convert .img in .ext4 using DiskInternals Linux Reader or Ext4Fsd.
  • 📂 Mount the image as a disk in Windows or Linux.

Method 3: Debugging via Android Studio

Android Studio provides advanced tools for working with files:

  1. Install Android Studio and connect the device.
  2. Open Device File Explorer (View → Tool Windows → Device File Explorer).
  3. View files in real time (access depends on rights).
⚠️ Attention: Working with partition images (.img) requires knowledge of their structure. Incorrect mounting can lead to data loss.
💡

If your goal is to simply view files without editing, use methods without Root (ADB or backups are needed only for deep changes.

7. Risks and how to avoid them

Working with system files Android is fraught with consequences. Here are the main risks and ways to minimize them:

Risk Consequences How to avoid
Deleting critical files The phone does not turn on (bootloop) Always make a backup before making changes
Change build.prop Corruption of applications or system Edit only known parameters
Unlocking the bootloader Reset to factory settings, loss of warranty Check the manufacturer's policy before unlocking
Installing an inappropriate one firmware Brick (complete failure of the device) Use firmware only for your model

Safety rules:

  • 🔋 Always check the battery charge (at least 50%).
  • 📋 Keep a log of changes (which files and why you edited).
  • 🔄 Test changes on custom ROMs before applying them on the main device.
  • 🛡️ Use trusted sources for downloading firmware and utilities (XDA Developers, official sites).

FAQ: Frequently asked questions

Is it possible to view Android system files without Root?

Yes, but with limitations. Through ADB you can view some files (for example, in /system), but you won't be able to edit them. You can also create a backup via adb backup and extract data from it. However, access to folders like /data without Root is closed.

Which file manager is better for working with Root?

The most popular options:

  • Root Explorer - classic manager with support Root and cloud storage.
  • FX File Explorer - fast, with built-in FTP server.
  • Solid Explorer - modern interface, support Root and archives.
  • Mixplorer - lightweight, highly customizable.

The choice depends on your tasks: for simple viewing, any is suitable, for complex operations (mounting images, working with symlinks) it is better Root Explorer or FX.

Which what to do if after editing the system files the phone does not turn on?

If the device goes into bootloop or does not respond:

  1. Try to boot into Recovery Mode (Power + Volume Up).
  2. If installed TWRPrestore the backup (Restore).
  3. If TWRP no, flash the stock firmware via Fastboot or Odin (for Samsung).
  4. As a last resort, use service utilities like SP Flash Tool (for Mediatek) or QFil (for Qualcomm).

If all else fails, contact the service center - you may need to flash the firmware via EDL-mode (emergency mode).

Is it possible to get Root on phones with Exynos or Kirin?

Yes, but the process may differ:

  • Exynos (Samsung): Use Magisk + patch for AP file: Since 2018, via Odin. On new models, you may need to bypass the RMM/Knox.
  • Kirin (Huawei/Honor): Since 2018 Huawei has blocked bootloader unlocking. On older models (up to Mate 10), you can use DC-Unlocker or FunTool.

For current models (Samsung Galaxy S22, Huawei P50) it is almost impossible to obtain Root without exploits that are quickly covered by updates.

How to protect system files from changes?

If you are afraid of accidental changes:

  • 🔒 Disable Root access for applications in settings Magisk.
  • 📋 Regularly create backups via TWRP or ADB.
  • 🛡️ Install applications to monitor changes (for example, AFWall+ to control network access).
  • 🔄 Use Read-only mount for the system partition (via TWRP or init.d-scripts).
