I just had the same issue. I have an original mcModule 110 and trying to get into it to do an update. I did the erase script, which went through fine. Then I did Erase database, and it "Erase Failed!" and now I can't connect to it. I've tried a couple batteries, and the red light doesn't flash. I think I bricked it. Also, I had just installed OTA app and mcStudio onto my PC for the first time.
