- Click download to get `ELEGOO_UPDATE_DIR.zip`.
- Unzip and copy the `ELEGOO_UPDATE_DIR` folder to an empty USB drive (root level).
- Safely eject, insert into your ELEGOO Neptune 4 series printer, then power it on.
- The printer applies the update and WiFi credentials automatically on boot—wait for the second boot/light-up before removing the USB.
- Plug a supported USB WiFi dongle (tested: TP-Link TL-WN725N, buy it here).
