How to Change Read-Only File System to Read-Write on Android

Changing the read-only file system to read-write on Android can be a daunting task, especially for those who are not familiar with the intricacies of this operating system. However, it is an important skill to have, as it allows you to modify and customize your device in ways that are not possible with a read-only file system. In this blog post, we will explore the challenges of changing the read-only file system to read-write on Android, and provide you with several methods to accomplish this task.

The Challenge of Changing the Read-Only File System to Read-Write on Android

Changing the read-only file system to read-write on Android comes with its fair share of challenges. Here are a few key points to keep in mind:

  • Android devices are typically designed with a read-only file system to prevent accidental or unauthorized modifications to the system files. This ensures the stability and security of the device.
  • Modifying the read-only file system requires root access, which is essentially gaining administrative privileges on your device. Rooting your Android device can void the warranty and may introduce security risks if not done properly.
  • Some manufacturers make it more difficult to gain root access on their devices, implementing additional security measures to prevent unauthorized modifications. This means that the methods for changing the read-only file system may vary depending on the device make and model.

Now that we understand the challenges, let’s explore some methods to change the read-only file system to read-write on Android.

Method 1: How to Change the Read-Only File System to Read-Write using ADB

ADB (Android Debug Bridge) is a command-line tool that allows you to communicate with an Android device. Here’s how you can use ADB to change the read-only file system to read-write:

1. Enable USB debugging on your Android device. To do this, go to Settings > Developer Options (If Developer Options is not visible, go to Settings > About Phone and tap on the build number 7 times to enable Developer Options). Once in the Developer Options, toggle on the USB debugging option.
2. Connect your Android device to your computer using a USB cable.
3. Open a command prompt or terminal window on your computer.
4. Navigate to the directory where ADB is installed. This is usually the platform-tools directory in the Android SDK folder.
5. Type the following command to verify that your device is recognized by ADB: adb devices
6. If your device is recognized, you should see a device ID in the output.
7. Run the following command to gain root access: adb root
8. Once you have root access, run the following command to remount the system partition as read-write: adb remount
9. Your system partition should now be remounted as read-write, allowing you to make modifications. You can verify the status by running the command: adb shell mount | grep -i /system

Pros:
1. ADB is a powerful tool that allows for precise control over an Android device.
2. The method is applicable to a wide range of Android devices.

Cons:
1. ADB requires some technical knowledge to use effectively.
2. Rooting your Android device can void the warranty and may introduce security risks.

Method 2: How to Change the Read-Only File System to Read-Write using a File Manager App

If you prefer a more user-friendly approach, you can use a file manager app with built-in root functionality to change the read-only file system to read-write. Here’s how you can do it:

1. Install a file manager app with root functionality from the Google Play Store. Examples include Solid Explorer, ES File Explorer, and Root Explorer.
2. Launch the file manager app and grant it root access when prompted.
3. Navigate to the file or directory you want to modify in the system partition.
4. Long-press on the file or directory, then select the "Properties" option.
5. In the properties window, look for the permissions section and make sure the "Write" permission is enabled.
6. If the "Write" permission is not enabled, tap on it to toggle it on.
7. The file or directory should now be writable.

Pros:
1. File manager apps are generally more user-friendly and easy to navigate.
2. No need for command-line knowledge or ADB.

Cons:
1. The method may vary depending on the file manager app you use.
2. It may not work if the manufacturer has implemented additional security measures.

Method 3: How to Change the Read-Only File System to Read-Write using a Custom Recovery

Another method to change the read-only file system to read-write on Android is by using a custom recovery. Custom recoveries like TWRP (Team Win Recovery Project) provide additional features and options compared to the stock recovery. Here’s how you can use TWRP to make the necessary changes:

1. Download the TWRP recovery image for your device from the official TWRP website (https://twrp.me/Devices/).
2. Install the necessary drivers on your computer for your Android device.
3. Enable USB debugging on your Android device.
4. Connect your Android device to your computer using a USB cable.
5. Open a command prompt or terminal window on your computer.
6. Navigate to the directory where ADB is installed.
7. Type the following command to boot your device into fastboot mode: adb reboot bootloader
8. Once in fastboot mode, flash the TWRP recovery image by running the command: fastboot flash recovery twrp.img (replace "twrp.img" with the actual filename of the TWRP image).
9. After flashing TWRP, boot your device into recovery mode by running the command: fastboot boot twrp.img (replace "twrp.img" with the actual filename of the TWRP image).
10. Once in TWRP recovery, navigate to the "Mount" menu.
11. Tap on the "System" partition to mount it.
12. Go back to the main menu and tap on "Advanced," then "File Manager."
13. Navigate to the file or directory you want to modify in the system partition.
14. Long-press on the file or directory, then select the "Permissions" option.
15. Enable the "Write" permission and save the changes.
16. Reboot your device.

Pros:
1. Custom recoveries provide advanced features and options.
2. The method allows for a more fine-grained control over the system files.

Cons:
1. Flashing a custom recovery can void the warranty and may introduce security risks.
2. The method requires a compatible custom recovery for your device.

Method 4: How to Change the Read-Only File System to Read-Write using a Custom ROM

If you are comfortable with more advanced modifications, you can install a custom ROM on your Android device to change the read-only file system to read-write. Custom ROMs are aftermarket firmware that brings additional features and customization options. Here’s how you can do it:

1. Research and find a custom ROM that is compatible with your device. Websites like XDA Developers (https://www.xda-developers.com/) are good resources for custom ROMs.
2. Download the custom ROM for your device from a trusted source.
3. Install the necessary drivers on your computer for your Android device.
4. Enable USB debugging on your Android device.
5. Connect your Android device to your computer using a USB cable.
6. Push the custom ROM file to your device using the following command: adb push custom_rom.zip /sdcard/
7. Disconnect your device from the computer and reboot it into recovery mode.
8. In the custom recovery, perform a full system backup to ensure you can revert if something goes wrong.
9. Wipe the system, data, and cache partitions.
10. Install the custom ROM from the ZIP file you pushed to your device.
11. Reboot your device and enjoy the new custom ROM.

Pros:
1. Custom ROMs provide extensive customization options and additional features.
2. The method allows for a complete overhaul of the device’s software.

Cons:
1. Flashing a custom ROM can void the warranty and may introduce security risks.
2. The process is more advanced and carries a higher risk of something going wrong.
