Hi. Just got the X Cube Mini with Firmware 1.02 installed but smok seems to have a later version available. Every time I try to "check version" it says it failed. Not sure why this keeps on happening. It states you are supposed to do this before you plug in the mod but I just can't figure it out and there are no good YouTube tutorials to show...in fact, I could only find one and that guy even had problems. Any advice? Do I even need to upgrade? Thanks for any help and guidance on this one!
