SXmini G and T classes, and Evolv DNA C chipsets it can be done easily.
Vaporesso over time has lost a lot of customisation in their tools, years ago you could change the images and text to whatever you wished. But no more unfortunately.
But I've not heard of any customisation when it comes to Vaporesso for quite some time
@Superuser187.
But for current devices that you can easily customise visually, you're probably looking at the Evolv DNA75C and DNA250C chipset mods. As Escribe, the custimisation and monitoring software also has a theme editor.
When you have a chance you may wish to watch a few YouTube videos about Escribe though.
