1. ⚠️ WARNING:

   Flashing incorrect firmware can brick your ONT. Ensure you have the exact file for your hardware revision (e.g., F670L V1 vs V2). Also, some ISPs lock firmware upgrades. If your “Upgrade” button is greyed out, you may need to request the update from your ISP or use a technician-level firmware tool.
