I loaded the Arctic Fox firmware on my Cuboid and all of the 510 issues went away. This firmware is awesome. It add much more control to pretty much all Joyetech, Eleaf and Wismec mods. It allows you to set up and monitor the performance of your mod from your computer as well.
I am running it on the the Cuboid, Cuboid Mini, VTC Mini and RX200s.
Ceck it out. http://nfeteam.org/
