Important things to know beforehand

• It is recommended to connect your machine to your computer with a USB cable for the upgrade.
• During the upgrade, ensure that the power supply, Internet, and USB connection are stable and secure.
• Keep your computer in an active state during the upgrade. Do not let it go into sleep, hibernate, or shutdown state.
• During the upgrade, ensure that xTool F1 Lite is on and its touchscreen controller and other accessories are connected.

Upgrade the firmware

(1) Ensure that your computer is connected to the Internet. Open XCS on your computer, and then connect xTool F1 Lite to XCS via a USB cable.

(2)  In the top-right corner of XCS, click the  icon next to the image of xTool F1 Lite.

(3) On the pop-up Device settings window, click Check for updates under Firmware version. If a new version is found, update the firmware.

How to deal with firmware upgrade failure

• Check the network. If there is a network exception, repair the network and try updating the firmware again.
• Check the device connection. Ensure that the device is stably connected to XCS by using the USB cable. If the device is disconnected from XCS, reconnect them and try updating the firmware again.
• Check the firmware version. The firmware has been upgraded, but the error on XCS shows that the update failed. In this case, restart the XCS software, enter the firmware settings page, and check whether the firmware version is updated. If there is an update, the firmware update is sucessful.
• Failure of the firmware upgrade may occur due to unexpected conditions like computer hibernation, shutdown, or a sudden power loss in the F1 Lite. In such cases, restart both the F1 Lite and the computer, then try updating the firmware again.
