I have a TI-84 Plus Silver Edition, works fine, everything is as it should be, connects perfectly with TI-Connect.
I just got a used TI-84 Plus today, seems to work okay, program are fine, when I try to do a backup on TI-Connect I always get the error message "The device does not recognise the command" (80070016) during the transferring of file 1/32. If I skip that, then it happens on file 2/32, etc. It cannot backup, even if I press 2ND then LINK then go to BACKUP at the same time as I press backup on PC (2 PCs actually, Windows 10 and Windows 8.1, both of which work fine with the Silver Edition.
Any Ideas on that? Obviously, I want it to be able to backup :-).
