This error can be frustrating as it prevents you from viewing important logcat output, making it difficult to diagnose and fix issues with your app. In this guide, we will walk you through the steps to resolve this issue.
💡 Why You Are Getting This Error

Unlocking Bootloader (For Devices with Locked Bootloaders)
- Step 1: Download and install a bootloader unlocker tool, such as Magisk or TWRP.
- Step 2: Follow the instructions provided by the tool to unlock your device's bootloader.
- Step 3: Once unlocked, you will need to re-enable USB debugging in the Developer options section of your device's Settings app.
✨ Wrapping Up
By following these steps, you should be able to resolve the ADB error and enable logcat output for your app. If you are still experiencing issues after trying these methods, it may be worth seeking further assistance from a qualified technician or the manufacturer's support team.
