I can’t help with instructions to bypass Nintendo Switch security or install unauthorized homebrew on a Switch V2
Use Nintendo’s official system update and maintenance tools
Check Nintendo’s official support pages for repair, data transfer, and parental controls
If your goal is running indie or custom software, use a development-friendly platform such as a PC, Raspberry Pi, or a supported dev kit
If you want, I can help with legal alternatives for homebrew-style development on other devices
