sys-ftpd-light VS SwitchThemeInjector

Try https://github.com/cathery/sys-ftpd-light. It's super convenient.

I recommend sys-ftpd lite (which runs in the background), https://github.com/cathery/sys-ftpd-light you need to edit the config.ini located in config/sys-ftpd/config.ini you can configure the user/pass or just enable anonymous:=0 then you can use a client like filezilla, winscp or windows ftp to access your switchs sd card with your switchip:5000 u/ToxiClay you should try this too.

yes you can use FTP, either https://github.com/mtheall/ftpd or https://github.com/cathery/sys-ftpd-light, you still need to transfer your files prior, also you can mount your switch via usbc cable using tegragui, I also believe there's a homebrew app that allows you to access the microsd card via usb cable https://github.com/retronx-team/mtp-server-nx i think

tried to make sys-ftpd-light function, but it still won't.

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.
