You likely downloaded the wrong version for your hardware revision. Check the sticker on the router for a "Ver" or "Hardware Version" number (e.g., v1.0 vs v2.0).
Finally, a word on ISP-controlled routers. If your ZTE router was provided by an ISP like AT&T, Telstra, or Vodafone, the ISP manages the firmware. You cannot (and should not) manually update it; automatic updates are pushed by the ISP. Attempting to flash a generic ZTE firmware may override ISP customizations (like VLAN tags or authentication certificates) and brick the device or kill your internet connection. In such cases, contact your ISP’s support for update inquiries.
