Before upgrading the firmware, please ensure that the USB DAC driver(Click here) has been installed. It is recommended not to connect the computer to other devices except the K7 BT to avoid upgrade failure: 


Upgrade steps:

1、After the computer is connected to K7 BT, switch [INPUT] to USB mode; double-click "FiiO_Dfu_K7BT", and the firmware "K7BT_xmos_v110_dfu(RGB_OFF).bin" will be automatically detected, as shown in the figure below:


2、Click "Start" to start the upgrade. Before the upgrade is completed, please do not interrupt or close the interface; after the upgrade is completed, when the interface displays "Firmware upgrade finished successfully", it means the upgrade is successful. At this time, the RGB light of K7 BT will go out!
