I dont think its broke, i remember using an iclear30 on my vamo v5. With 2.2 coil head stock.. It was in there for 2 1/2 3 weeks ( the head ). One day i went to go and take a vape on it, was using other mods but my iclear 30 is for a specific juice. Took a vape and only lasted for a second. So tryed again nothing said short like yours, put my nautilus on there samething, other tanks same thing. Opened all tanks checked all coils. The iclear30 coil popped so i changed it, turned off the vamo v5 took batt out then back in on etc. then re did RMS mode put iclear30 back on and been working fine for awhile now. It even took a 7ft fall O_O and survived ( the x.1 is now slanted lol ) works like a champ, i dont hear the rattlesnaking now lol hope that helps man
