How to use OTA to update the firmware of SOVOL Zero

3. Before upgrading the firmware, please connect to the network. You can use the cfg file in the USB to connect, or you can use the LAN cable to connect. (The printer only supports 2.4G network. If it is a dual-band signal, please turn off the 5G network. Please make sure that the network signal remains good. It is recommended to use a LAN cable for firmware upgrade)
(1) Use Notepad to open the cfg file and enter the WIFI account and password. Please make sure that the WIFI information is correct. The network SSID name cannot contain spaces or underscores due to certain restrictions of Linux (for example, the SSID name "network_ name" is not acceptable, it must be "networkname").
- The security type in Linux network management can only be WPA2, not WPA3
If 127.0..0.1 appears, it means that the WIFI connection is not successful. Please unplug the USB and plug it into another port. If you still cannot connect to the network, please try to shut down and restart or change other WIFI signals.
Insert the USB, click Advanced, click Show IP, and the current IP address of the printer is displayed, indicating that the network connection is successful. Continue to step 4
