Step-by-Step Solution

  1. Deep Power Off: Unplug the power cord for at least 30 seconds.
  2. Memory Clear: Disconnect all network or USB cables to see if the error persists without external load.
  3. Factory Reset: Try to access the configuration menu to reset settings (only if the error allows access).
  4. Firmware Update: Download the latest firmware version from the official website and update it via USB.
