Android Rooting Techniques if Necessary (en)

What is Rooting?

Rooting is the process of gaining root (full administrative) access to the Android operating system. With root access, you can perform deep customizations on your device, install applications that are not available on the Google Play Store, improve performance, and much more.

Why Use ADB?

Android Debug Bridge (ADB) is a versatile tool that allows you to communicate with your Android device from your computer. With ADB, you can run various commands to manage your device, including performing rooting.

Warning:

• Rooting voids your device warranty.
• The rooting process can risk damaging your device if not done correctly.
• Ensure you have backed up important data before proceeding.

Prerequisites:

• Android Device: Make sure your device has developer options and USB debugging enabled.
• USB Cable: To connect the device to the computer.
• Ubuntu Linux: The operating system to be used.
• Android SDK Platform-tools: A package containing ADB and other tools.

Steps to Root:

1. Install Android SDK Platform-tools:

• Open a terminal in Ubuntu.
• Run the following command:

sudo apt-get install android-sdk-platform-tools

2. Connect the Android Device:

• Connect the Android device to the computer using a USB cable.
• Ensure the device's USB drivers are installed correctly.

3. Verify Connection:

• Open the terminal and run the command:

adb devices

• If the device is detected, the device's serial number will appear.

4. Unlock Bootloader (If Necessary):

• Some devices require an unlocked bootloader to be rooted.
• The method to unlock the bootloader varies for each device. It usually involves entering fastboot mode and running certain commands.

5. Flash TWRP (or other custom recovery):

• TWRP is a custom recovery that allows you to perform various modifications on the Android system, including flashing custom ROMs and rooting.
• Download the appropriate TWRP file for your device.
• Run the following command to flash TWRP:

    fastboot flash recovery twrp.img

Replace "twrp.img" with the name of the TWRP file you downloaded.

6. Boot into TWRP:

• Power off the device.
• Press the power and volume up buttons simultaneously to enter recovery mode.

7. Backup Data (Optional):

• Within TWRP, back up your important data before making modifications.

8. Flash SuperSU (or Magisk):

• SuperSU or Magisk are applications that provide root access to the device.
• Download the appropriate SuperSU or Magisk file for your device.
• Copy the file to the device's internal storage.
• From TWRP, select "Install," then choose the SuperSU or Magisk file you copied.
• Swipe to confirm the flashing.

9. Reboot the Device:

• After the flashing process is complete, select "Reboot system."

Complete Example:

# Install platform-tools
sudo apt-get install android-sdk-platform-tools

# Connect the device and check connection
adb devices

# Unlock bootloader (if necessary)
fastboot devices
fastboot oem unlock

# Flash TWRP
fastboot flash recovery twrp.img

# Reboot into TWRP and flash SuperSU
# (These steps are performed within TWRP)

Notes:

• Commands and file names may vary depending on the device and Android version.
• Always look for device-specific guides before starting.
• Rooting may void your device warranty.
• You are fully responsible for any risks that may occur.
