      What firmware revision are they running? Could be someone forgot to
      apply the latest update (which supports the patch commands.)

On one of the minis after i did the 0102 patch on reset it stopped turning on and booting.... the other mini took the patch and rebooted but no joy... I can send these 2 mini's back to you scott if you like and see what's up... I will order 2 of the larger t3's so i can use them on the event this weekend and not get pressured to get the minis up and running till after... I still have to get the micro's working tonight as it is...
