Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Device does not power on. | Battery may be depleted. Charge the device for at least 30 minutes. If the issue persists, try a different USB port or charging cable. |
| Cannot transfer files to the device. | Ensure the device is properly connected to the computer/smartphone. Try a different USB port or cable. For OTG transfer, ensure your smartphone supports OTG and use an appropriate adapter. Transfer files in smaller batches (under 1GB) for better stability. |
