I have a new X Cube 2, upgraded the firmware, and Smok still wants 2.99 to "activate" TC for stainless by using their stupid in app purchase. I'm betting that editing a line or 2 in the firmware, will activate it just fine. Could sombody who has the stainless TC on their X Cube 2 do a compairisone of the hex between the 2 firmwares? I think that Smok has begun engaging in fuckery here. They should have spent more time making sure the fire bars fit properly, and did not stick in the fire postion, and less time trying to nickle and dime their custys.
