I updated my 3ds to 10.5...but after that the home menu would not load. It would go to the power off screen if I briefly press the power button. When I try going to the home menu from there, I get stuck on the screen that says HOME MENU with the icon, but the home menu never comes up. Meanwhile if I remove my microSD, the home menu loads just fine with the default theme. From there I went and moved all signs of homebrew out of the SD card, and the home menu still wouldn't load, which leads me to conclude that it's the custom theme I had loaded on my microSD. So, I am wondering if it is possible to reset my theme to the default theme through the SD card since I can't do so through my 3ds? I also have an old 3ds at 9.9, but when I try using my SD card using a microSD adapter, none of the content loads, like none of my games or anything.
