您好,现在SBS页面的ManufacturerAccess 框中输入密码看是否能解码,如果能解码说明密码是对的。
再到SMB 界面中的60地址连续输入密码试一下。
详细请参考TRM B.16 UnSealKey (0x60)
您好,从Unsealed模式变为Full Access,请在ManufacturerAccess 下两遍FFFF,FFFF试一下。
修改密码方法如下:
The unseal key can be read and changed via the extended SBS block command UnSealKey when in FULL ACCESS mode. To return to the SEALED mode, either a hardware reset is needed, or the ManufacturerAccess seal device command is needed to transit from FULL ACCESS or UNSEALED to SEALED.
