Thanks for your reply. There is just no such folderThis issue comes up a lot. See the program numbers? Go to your switch folder in contents I believe and find that folder that matches the numbers next to program. It's the themes folder. Delete it. You had a custom theme installed before you updated or you didn't properly remove the theme before updating. Deleting the folder should fix this error.
Thank you for your reply. But even if I delete the entire content folder, I still get an error.It's been awhile. My bad. On your SD card go to atmosphere then contents. Then find that folder and delete it. Depending on how much stuff you have on your switch you it may take a minute to find.
