🧠 Requirements

• ADB (Android Debug Bridge) installed and available in your system PATH
• Root access enabled on each target Android device
• Devices must be accessible over the same network via adb connect
• Optional: a wallpaper.png file in the same directory (to set a custom wallpaper)

---

⚙️ Configuration

Open the script file (change.sh) and edit the following line to include your device IPs:

DEVICE_IPS="192.168.109.150|192.168.109.151|192.168.109.152|192.168.109.153"

📌 Devices should be separated by the pipe symbol (|).

---

🧩 Usage

Run the script in your terminal:

sh change.sh

The script will:

1. Connect to each device via adb
2. Gain root access
3. Apply all configurations (time, brightness, lock screen, etc.)
4. Push wallpaper (if available)
5. Reboot the device

---

📁 Log Output

All operations are logged to a file with a timestamp:

device_config_YYYYMMDD_HHMMSS.log

You can review logs to verify success or troubleshoot connection issues.

---

🖼️ Wallpaper Setup (Optional)

To set a custom wallpaper:

1. Place your image in the same directory as the script
2. Name it exactly wallpaper.png

If no file is found, the script will skip this step gracefully.

🛠️ Troubleshooting

• Device not found: Ensure the device is connected and accessible via IP. Test with:

  adb connect <IP_ADDRESS>

• Permission denied: Confirm the device has root permissions and ADB debugging enabled.

• Wallpaper not applied: Make sure the file wallpaper.png exists and has correct permissions.

---

🔒 Security Notes

• Only use on trusted networks
• Do not include unknown IP addresses
• Ensure devices are company-owned and rooted intentionally

🧠 Tip

To run automatically on startup, you can create a systemd service or schedule it via cron for maintenance routines.
