4. Backup DVR configuration to a USB drive (Settings → System → Maintenance → Export).
5. Ensure stable power and network during the process.

Troubleshooting & cautions

• If upgrade fails or DVR is unresponsive, do not unplug immediately; wait 10–15 minutes.
• If device becomes bricked, contact vendor support or an authorized service center — avoid attempting incompatible recovery files.
• Restoring settings from backup can help avoid reconfiguration but ensure compatibility with new firmware.
• Never use firmware intended for a different model or region.

When to skip an update

• If your DVR is functioning and release notes don’t list fixes or features you need.
• If you cannot ensure stable power or you don’t have a backup.
