I am trying to update my friends TI-Nspire in TI-84+ Mode to OS 2.55MP using the calc-to-calc cable, but when I connect the cable, the calculators freeze up.
Any reasons as to why, or solutions would be awesome!
You cannot update the 84+ OS of an Nspire by sending an 84+ OS update. You need to update the entire Nspire OS to do that. It sounds weird that the calcs freeze as soon as you connect the cable, though...
