I bought an Ego one mega, i didn't unpack it until after the warranty had expired (stupid i know) but basically everytime i fire it the device flashes 40 times and locks until i plug the charger into it, it'll then let me drag 1 maybe two clouds if i'm lucky, then lock again, my first 1.0 ohm coil worked perfect, but after i tried the temp control coils (NI and TI) (using temp control settings on both) this is where the device started this fault, on these two coils, so i order a pack of 5 1.0ohm coils and vaped under W mode again, however i am still having the 40 flash lock problem, any advice? Really missing my vape
