Troubleshooting KernelSU Service Issues: No Such File or Directory Error
in Post with 0 comment

This guide addresses a common issue encountered when setting up custom services with KernelSU: the 'No such file or directory' error. While KernelSU installation often proceeds smoothly, launching custom services can sometimes fail. This error typically arises from misconfigurations or path issues. Let's delve into potential causes and troubleshooting steps.

**Understanding the Error:**
When KernelSU fails to start a custom service with a 'No such file or directory' error, it indicates that the system cannot locate the service's executable file. This could be due to inaccuracies in the service's path, permission problems, or a discrepancy between installed APKs and the service's manifest.

**Troubleshooting Steps:**
1. **Verify Service Path:**
- Double-check the service's path in the KernelSU configuration. Ensure it accurately reflects the location of the service's executable file (e.g., /system/app/your_app_name/your_service.apk).
2. **Check APK Installation and Permissions:**
- Ensure the APK containing your service is properly installed and accessible by the system.
- Verify the service's permissions within the APK's manifest. It should have the necessary rights to run as a system service.
3. **Compare with Existing APKs:**
- Analyze how other system APKs are mounted and configured. Compare your service's APK structure and file naming conventions to those of system APKs.
4. **Log Inspection:**
- Examine KernelSU logs for more detailed error messages. These logs can provide valuable insights into the exact cause of the failure. Look for messages related to file access or permission errors.
5. **Test with a Simple Service:**
- Create a minimal, test service with a basic executable to rule out complex issues within your main service.

**Additional Considerations**:
If you're modifying the /system partition, ensure you've taken appropriate backups and are familiar with the potential risks involved. Make sure your modifications are compatible with your device's operating system version and KernelSU configuration.

**Need More Help?**
If you've followed these steps and are still encountering issues, consider providing the following information for further assistance:
- Device model and Android version
- KernelSU version
- Relevant code snippets from your service implementation
