Unable to update my prime

[Marcelo Vanti]

Hi all,
I followed the footsteps of hp conectivity kit to update the fimware to my new Prime, but it not worked for me. When the update starts, the calc disconnects from CK, and an error message (update failed (104)) is shown. The same thing occurs in all USB ports. The calculator remains in recovery mode and so I need to reset it.
Please, any help is welcome
