Hello,
i dont really understand what you need. if you plan to clone the firmware of the ssd to the ultra plus ssd, just for your info you cant. all the firmwares for the ssds are unique so you cant just copy randomly ones.
you can download for free the ssd dashboard from sandisk site and see if the ultra plus has another firmware update itself.
