I received my unit a few days ago it came with version DRAG V1.0.0.1. I downloaded the app and update flies Version: V1.5.1.26. I was able to edit the start screen and have my name appear. I found 27 files in the Resource file and put about 7 in the unit, so I now have a voltage mode and a power mode for wattage. I was able to find the Drag V1.0.01 and downloaded that file so I would be able to bring it back to the original state it was in when I received it. It would have been nice to know what the files being put in were. Any info on this would be helpful.
