Hi David,
Thanks for the recommendation I am trying to use your suggestion of using the app but having a problem with "No valid DFU device found."?

PROBLEMS UPDATING FIRMWARE ON TINY SA ULTRA
Powered device off, pushed down jog button all the way while powering on device. A black screen appeared as expected. Did not connect since device did not show up the list of com ports when device is powered on in this manner. COM port USB cable plugged in the entire time.
"No valid DFU device found."
What am I doing wrong???
?
