When the copy progress bar completed, that means the upgrade is completed, eject the "TTARTISAN" USB drive and unplug the Type-C USB cable (as shown in Figures 9).

LAST STEP.

Wait 5 seconds and then reconnect to the computer via Type-C USB cable, then click TTARTISAN->DeviceInformation.txt to check the version number. If it is the latest version number, the firmware update is successful(as shown in Figures 10).
