Connect your phone to computer. slide your finger from top to bottom of screen. Select usb mode then ok. Find file on tour computer, highlight it, right click, send to what ever hub you have it plugged into. Since I synced my phone to my computer it says Droid X. Unplug phone after status bar says that it is done. Hope that is clear enough for you. You did get the correct theme right. The one for the DX that will work with your system.
