This is the easiest way to ensure you have the latest software version directly from ZTE.

Use this when OTA fails, you have a downloaded .bin or .pkg file from ZTE support or a forum, or you are cross-flashing carrier versions.

Click the Check button in the "Check New Version" section.

The router will download and install the update automatically. Do not power off the device during this process. Method 2: Manual (Offline) Firmware Installation

: Go to Settings > Device Settings > Update Management .
