7. Troubleshooting Common Issues

• "File type is invalid" Error: This usually means you downloaded firmware for the wrong Hardware Version (e.g., trying to flash A2 firmware on an A1 device). Double-check the sticker on the bottom of the router.
• Router Bricked (Power LED blinking): If the power light is blinking green/red and you cannot access the interface, the firmware flash failed. The DWR-M960 does not always have a simple recovery mode; you may need to contact D-Link technical support for a recovery file or procedure via TFTP.
• SIM Locked: If a firmware update locks your SIM, you may need to re-enter the unlock code provided by your carrier.

6. Hardening Recommendations for D-Link

Based on the analysis of the new d39link firmware, we recommend: "File type is invalid" Error: This usually means

1. Remove AT passthru: The lte command should be removed or require cryptographic authentication.
2. Fix DHCPv6 bounds checking: Implement __builtin_object_size checks or replace memcpy with memcpy_s.
3. Encrypt static strings: The "d39link_supervisor" credential should be derived from a TPM or secure element.
4. User Action: Disable IPv6 on LAN/WAN interfaces if firmware cannot be updated. Block UDP port 546/547 internally.
