I have same problem with Therion DNA166 from box. I have inserted batteries and see blinking logo Lost Vape when push the fire bottom. If I press bottom longer the second I see «check battery» and logo of empty battery. Installing SP5, restoring defaults, using another part of batteries does not help. If I try to do hard or soft reset in Escribe it says «Hard/soft reboot command issued» and nothing happen. Device Monitor in Escribe shows in Cell 1: 0,01V, in Cell 2: 5,20V. I donât know what to do. Please help.
