Note: You can also restart XCS and view the firmware version in Device settings > Basic info > Firmware version.

(2) Check the network 

If there is a network exception, repair the network and try updating the firmware again.

Ensure that the device is stably connected to XCS by using the USB cable. If the device is disconnected from XCS, reconnect the device by using the USB cable and try updating the firmware again.

Note: Using the USB cable to connect the device to XCS provides a more stable connection. If you are using the Wi-Fi connection, the firmware update may be interrupted due to an unstable network.

The firmware update may fail if any of the following occurs during the process:

• The computer enters sleep or hibernation mode

• xTool F2 Ultra is cut off from the power supply

Check your computer settings and the power supply. Ensure that the computer stays active and the power supply is stable. Then, try updating the firmware again.
