| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | | ISP pushed a new config during the time you were working. | Disconnect fiber, factory reset again. Do not reconnect fiber until TR-069 is disabled. | | Bridge mode kills all internet | You forgot the VLAN ID or your router doesn't support VLAN tagging. | Set your personal router's WAN to VLAN ID (usually 10 or 35). | | Web page shows "404 Not Found" | The ISP custom firmware removed the debug pages. | You must use Method 2 (Fiber Recovery). There is no software workaround for these units. | | ONT keeps rebooting | Your modified config corrupted the boot loop. | Use a serial TTL adapter (3.3V) on the internal UART pins to interrupt boot and force a TFTP recovery.
