  + "서비스 불가능 지역입니다. (This service is not available in your region)" 오류가 뜬다면 본체 설정에서 기기의 국적을 2.1.0 CTRTransfer에서 설치한 NAND의 지역에 맞게 바꿔 주세요.
  + CTRTransfer 작섭 중 청소년 보호 기능을 끄는 것을 깜박했거나 다른 이유로 무선 통신 설정에 접속할 수 없다면, 기기가 `attwifi`라는 이름의 네트워크에 비밀번호 없이 자동으로 접속할 것이라는 것을 명심해 주세요.
  + 다른 오류가 뜨면 이 [문제 해결 가이드](troubleshooting#ts_browser)를 참고해 주세요.

  + **"Show NAND or user string in System Settings"**
1. (start)를 눌러 저장하고 기기를 다시 시작해 주세요.
