Troubleshooting / upgrade checklist

  1. Record ONT model, serial number, MAC address and current firmware version (from device web UI or sticker).
  2. Contact ISP support for official firmware and upgrade window.
  3. Confirm upgrade method (TR-069 push, web UI upload, TFTP).
  4. If web/TFTP upload is permitted, verify firmware checksum and compatibility.
  5. During upgrade: do not power-cycle; keep logs and screenshots.
  6. After upgrade: verify WAN connectivity, VLAN/VoIP/IPTV functions, Wi‑Fi settings, and restore any saved config.

10. Final Thoughts

  • Stay on the official firmware unless you have a compelling reason to switch to a custom ROM.
  • Back up first – a simple copy of the /sdcard folder and a Nandroid backup are cheap insurance.
  • Follow the checklist step‑by‑step; the process is straightforward for the F670L because it uses a MediaTek chipset and SP Flash Tool is the standard flashing utility.
  • Keep the firmware file saved in a safe location for future restores; the same file works across many ZTE F670L variants as long as the region code matches.
