| Error Message | Likely Cause | Solution | | :--- | :--- | :--- | | | The file is corrupted or not intended for your exact hardware revision. | Re-download fw5000.upd from the official vendor portal. Verify SHA-256 checksum if provided. | | "Update failed: File too large" | The device’s flash memory partition is smaller than the file. | This often means you are trying to load a full-feature firmware onto a stripped-down model. Contact support for the lite version. | | "Timeout during erase" | Interference on the communication bus (serial/UART) or faulty flash memory. | Retry using a direct Ethernet cable (not Wi-Fi). If using serial, lower baud rate to 115200. | | Device reboots continuously after update | The new firmware has a configuration incompatibility. | Perform a factory reset by holding the reset pin for 30 seconds immediately after POST. | | File not recognized by loader | The .upd extension is associated with another program on your PC. | This is a false alarm. Do not open the file locally. Use the device’s built-in updater only. |
