| Error Message | Cause | Solution |
| :--- | :--- | :--- |
| "Firmware file mismatch" | You downloaded firmware for the wrong hardware revision (e.g., V1 vs V2). | Check the hardware version on your router sticker. Download the exact match. |
| "Integrity check failed" | The .bin file is corrupted or tampered with. | Re-download the file. Ensure your antivirus isn't blocking it. |
| "Connection lost" during update | Ethernet cable came loose or PC went to sleep. | Do not click anything. Wait 15 minutes. If bricked, use the TFTP recovery method. |
| Update tool is greyed out | The router is currently in bridge mode or managed by an ISP TR-069 protocol. | Contact your ISP. They control updates remotely; you cannot override it. | | Error Message | Cause | Solution |
