I mean, I assumed there must have been a TI-Nspire OS 1.1 and 1.2 at some point, but I’ve never seen them, and I’ve been looking at these devices pretty much since they were first released. I’ve got a kid that showed up with 1.1.” I told him he must be mistaken. So back in the spring, my math team assistant coach popped into my room and said, “I need help with an Nspire upgrade. If a kid shows up with a version older than 2.0, generally 1.4 or 1.7, my colleagues bring the Nspire to me to oversee the upgrade process. At our school, we want everyone running the same operating system, so we upgrade them to the latest version immediately. This is generally no problem, as TI has provided upgrades all the way back to the original TI-Nspire Clickpad. Sometimes students purchase older used Nspires on eBay or Amazon to save a few bucks. The Nspire may refuse to upgrade for many attempts, it my require a full system wipe, and on rare occasions, the upgrade bricks the device. If you’ve upgraded enough TI-Nspires (and I’ve probably upgraded a couple thousand times over the years), I don’t need to tell you that while the process is typically very smooth for 2.0 and above, sometimes older versions of the OS are stubborn. That includes what I’d call “unusual” upgrade problems. I took the pictures at the time but started my online data science studies shortly thereafter and just never got around to writing the story, but it was such an unusual thing that probably once a month I’ve continued to think about writing it up.ĭuring my years of teaching at my school, I’ve been the guy who troubleshoots all of the graphing calculator problems for teachers and students alike. I need to preface this story by saying that this is something that happened over 6 months ago.
