Sorry if this has been answered before, but I couldn't find any threads with my specific problem. I downgraded my N3DS a while ago, and I chose to format my EMUnand instead of my SYSnand so I could keep my original NNID as clean as possible in case I ever wanted to just update back to normal. Anyway, I don't remember how but I got a custom theme installed on my EMUnand, and when I went to change it to something else it didn't work, and now I don't have a theme. I don't have internet access on my 3DS at the time, and I guess all of the ways I have of installing themes requires me to download a theme from the eshop first. If I had a custom theme at one point, it seems there should be a way to at least install one. I tried CHMM, a cia of a theme, and homemenu hax with Tinker (hoping that since I didn't have internet access it would just install the theme without the hax) TL;DR: I had a custom theme, now I don't, how can I install one without internet access or any other themes already installed?
