[list]
[*]Download WC 6.0: http://www.seeedstudio.com/forum/download/file.php?id=2488
[*]unzip it
[*]open file explorer an change where you unzipped WC 6.0
[*]switch your dso off
[*]Hold >[] Button (most left button) while switching DSO on. => Screen shows "... The DFU Virtual USB Disk" (last of four lines)
[*]connect dso to computer with usb cable => (waiting some seconds ...) new drive letter will appear
[*]copy app1.hex from unzipped directory to this new drive => new drive will disappear for a moment
[*]new drive will reappear. => you will see app1.rdy (if you see app1.err something went wrong)
[*]switch dso off and on => :) [/list]
