Not sure it's a UD03?
Boxes lie and labels fade. The app reads the model from the drive and shows you before anything happens. If it's a different drive, it tells you what it is.
What the flash does
Downloads the firmware, checks the files and the drive, asks you to confirm and hold, writes, then checks again. Firmware changes carry risk. Read the precautions first.
