Hi to everyone. After two falls (mod was still working) something rattle inside the mod, so I decided to disassembly it and see what is happening. Everything was normal so I assembled it again. After that the mod is not working. I can connect it to pc and display is turning on, battery is charging. After disconnecting, the mod turn off. When is connected to pc and atomizer is attached, the mod keeps restarting. Tried with different battery and attomizer, but it's still not turning on.
