IOS IOS IOS.. XD - 改機

我是日規的偽 4.1J, 我一直不了解目前系統 IOS 的狀態，

今天用了一個小工具來檢查 IOS 的狀態，得到的結果是:



IOS number Trucha bug Flash access Boot2 access Usb2.0 IOS tree

IOS61 (ver 4890) Disabled Disabled Disabled Disabled
IOS60 (ver 6174) Disabled Disabled Disabled Disabled
IOS56 (ver 4890) Disabled Disabled Disabled Disabled

IOS22 (ver 780) Disabled Disabled Disabled Disabled
IOS17 (ver 518) Disabled Disabled Disabled Disabled
IOS14 (ver 263) Disabled Disabled Disabled Disabled
IOS13 (ver 16) Disabled Disabled Disabled Disabled

從這邊可以看得出什麼嗎？
是不是有的 IOS 很舊，需要更新呢？

我用的工具是 SignCheck 0.3b
