My Vamo V2 just decided the other day it was done with me. Go to vape, nothing doing. Try settings. Nothing. Tried unlocking it, nope, and I even pulled and swapped batteries till all of my batts had been in it. Does anyone know if this is pseudo-common, and if it is, is there a good way to open the casing and repair a wire or replace a chip? Or is my new favorite toy just done for?
