Before You Mod Your Switch
Not Every Switch Can
Only unpatched consoles can run CFW without a hardware modchip. Check your serial number before buying anything or opening the console.
Online Bans
Nintendo bans consoles it detects running CFW, and a ban is tied to the hardware. Keep a modded Switch off Nintendo's online services.
Back Up Your NAND
Dump your NAND and keys before installing anything. Without that backup a bad flash can leave the console unrecoverable.
Own Your Games
Homebrew is legal; piracy is not. Only use dumps of games you actually own.
