ftpd VS SwitchThemeInjector

you can interact with your SD card without taking it out using FTPD

Run sys-ftpd or ftpd and access your files from a computer using an FTP client

Use FTPD for quick file transfers to the 3DS over wifi without the need of removing the SD card. Available in the Universal Updater app.

I don’t have what you’re looking for but I have a solution for your screwdriver problem. Here is a video explaining how it works.

I have ftpd on my 3ds and I use FTPCafe FTP Client on my Android phone, then i download DS roms on my phone, after this I share internet (hotspot) to my 3DS, start ftpd on it, then put the IP that it says on the phone.

I updated my whole setup to the latest of everything at the time of TotK release. I'm not running 16.0.3 though, still on 16.0.2 Make sure you installed the ips patches intended for 16.x https://github.com/exelix11/SwitchThemeInjector/releases

I got it to work, I guess the issue was that I downloaded nxthemesinstaller from the HB app store. I downloaded from here and replaced the .nro and now I can see the themes

Nxthemes is supported on ver16 if you already have the nxthemes installer on your switch it should automatically install the update itself if not here's the GitHub page https://github.com/exelix11/SwitchThemeInjector/releases

Saw this and figured it might be of a little use to you. You might end up redoing Atmosphere because it would seem something might be wrong with your install. Just a guess. https://github.com/exelix11/SwitchThemeInjector/issues/119

First off download your image and the layout provided in your Themezer link, then grab the Switch Theme Injector (download the latest .zip, not the .nro). Your image needs to be 1280x720 in size otherwise this won't work. The layout file is what will be altering the icons' position along with maybe some colors/aesthetics adjustments.
