    You will find the error code description in the SDK documentation.

    Either the recoveries you are attempting to run are corrupt or they are simply not compatible.

    S1040 usually has to do with MobileJ being edited. Have you used some xex to change the test kit to dev Kit or used anything to unlock the ability to see the flash partition of the kit?
