so i got the smok stick v8 via mail and i opened it up and everything was fine but i took one puff and then after, it has been blinking 4 times everytime i take a puff and it just wont fire i looked up in the internet and i saw that it has to do something about the atomizer connection i used a different mod to check if it is the atomizer connection and it has worked there what do i need to do to fix it? i changed the coil to a different one and it still hasn't puffed i also took the base of the tfv8 and checked it on another mod it worked perfectly fine so i know for sure it has to do with the mod but i don't really know what to do... hope you guys can actually help me...
