If your console already has an arm9loaderhax or boot9strap based custom firmware, you will need to follow the instructions indicated to upgrade your setup to a modern one.
If your console has a menuhax-based CFW setup, you should [clear HOME Menu's extdata](troubleshooting#clear-home-menu-extdata), then follow all instructions on your SysNAND. You probably a menuhax-based setup if your system version when booting without an SD card is 9.2.0-20.
If you see something not described by the above options, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.
