1. Preconditions and risks

• Back up configuration: Save the current device configuration (WAN, LAN, VLAN, PPPoE credentials, VoIP settings) before updating. Misconfiguration may require re-provisioning by your ISP.
• Power stability: Use an uninterrupted power source or ensure the device won't lose power during update; power loss during flashing can brick the device.
• ISP restrictions: Many ISPs lock ONTs to their firmware or require signed images; attempting to flash unofficial firmware may break provisioning or void service support.
• Compatibility: Installing firmware for a different hardware revision or region can brick the unit. Confirm the model and PCB/hardware version.
• Legal/contractual: Check your ISP’s terms—modifying firmware might violate service terms.
