Just got my lost vape paranormal dna250c two days ago. Having the same problem the mod fire by itself. This will happen whenever I changed the atty or attach the atty after disconnect from eScribe. It immediately blow my coil. However, an unnecessary precaution help to prevent this from happening. Whenever I want to attach a new atty, First, I have to press the fire button until it display no atomizer, then press fire 5x to lock the mod, then only I can screwed in new atomizer. Seems like a glitch on the software... Everytime I wanted to change the atty, I have to repeat this procedure again...
