Hey all. I just received 2 Slice SE's in silver from Vaporcube. For $15 bucks each, why not. This lot must have been lost or hidden though cause the firmware on both is 1.2.1. Any idea how I can get to 2.5.7 since Hohmtech doesn't support them anymore? Sorry if this is readily available information but I'm having a difficult time locating it. I'm trying to quit smoking and my first foray into vaping was to get two Slices and a G2 which apparently get their best performance from recent firmware.
