How to deal with firmware upgrade failure

1. Check the firmware version
   The software may prompt you that the firmware update fails, even though the update actually succeeds. To check if an update succeeds, view the firmware version on the touchscreen to know if it is the latest version.

2. Check the network
   If there is a network exception, repair the network and try to update the firmware again.
3. Check the device connection
   Ensure that the device is stably connected to xTool Studio through the USB cable. If the device is disconnected, reconnect through the USB and try to update the firmware again.

4. Check the computer status and the power supply for xTool F1 Ultra

The firmware update may fail if:

• The computer goes into sleep or hibernation mode.
• The computer is turned off.
• xTool F1 Ultra is disconnected from the power supply.

To avoid this, check your computer settings and the power supply. Ensure that the computer stays active and the power supply is stable. Then, try to update the firmware again.
