Is it in any way possible? My first thought was simply to download the latest CAS operating system and update my calc with it, haven't tried as of yet as my computer cable has gone missingfor the moment, however I seriously doubt it's that easy otherwise everyone would be doing it. I have 2 ti-spire CAS clickpads, both of their screens got damaged, they flicker and one of the screens has gone blue. However if I hold them in the sunlight and squint I can just see the screen and they appear to be working fine, the screen just can't be read. So any way any of these calcs can be fixed so I have a working Ti-nspire CAS? Thanks in advance for any help!
