이미 커펌이 되는 제품을 

https://damota.me/ssnc/checker/ 여기서 조회를 해봤는데 

XAK로 시작되는 번호는 그냥 WARNING으로 뜨네요.. 

다른 기기로 조회를 해도 전부다 WARNING으로 뜨네요.. 

그런데 https://ismyswitchpatched.com/ 여기서는 전부 다 조회가 가능 다더군요~

저는 밑에서도 질문 했지만 XAK10005 5월 제퓸이겠죠? 이건 윗 사이트에서는 조회 안되고

밑에 사이트에서는 문제 없는 제품으로 나옵니다. 

웃긴건.. https://damota.me/ssnc/checker/ 여기서는 XAW XAJ 등 이런번호는 잘 나오는거 같더군요~ 즉 여기서는 XAK의 정보는 없어서 조회가 안되는거 같더군요~~

암튼.. 본인의 시리얼번호가 

XAK이면.. https://ismyswitchpatched.com/ 여기로 조회하는게 정보가 나옵니다. 

https://damota.me/ssnc/checker/ 여기서 조회를 하면 XAK에 대한 정보가 없어서 WARNING으로 만 뜹니다.. 

밑에 참고 하세요
