James,Thank you for contacting Texas Instruments.I will be more than happy to answer your questions about the TI-Nspire with ClickPad.From time to time Texas Instruments will update the Operating System (OS) of its products. This is done to enhance the features of the products. Some of these changes may require updates that will prevent the handheld from downgrading to a lower OS.Another resource you can use to find answers to your questions, example calculations and other information is our Knowledge Base. The Knowledge Base is accessible to you 24 hours a day, 7 days a week.http://support.education.ti.comI hope that you find this information helpful. If you have further questions or comments, please feel free to send me an email.Warmest Regards,Cesar Lopez
Thank you for your reply.I like to do a little asm coding and other types, and i can not see how these changes would need to prevent the downgrading of an operating system. To me it seems like it would take more work as you would have to specify in newer operating systems that it would be allowed to be upgraded. What kind of features are there that require that there be no downgrades? Is it that there were permanent changes to some kind of boot to method making downgrading unstable and dangerous?Thank you,- james
lol, ask if using nleash is a good idea!

I have noticed the lack of 3D graphing in the Nspire products. As such, I have made my own 3D graphing program to do it. Initially, it was in TI-BASIC, but that ended up being much too slow and cumbersome, due to the number of lines that had to be drawn. I decided then, to use Ndless, a tool to run assembly progams on handhelds, and write a 3D grapher in assembly language. It runs much faster, but I am frustrated at the fact you must use OS 1.1 to run it, therefore sacrificing all the other math features added in later OSes. Is there a way to make this run on later operating systems? (Also, I am not concerned about not being able to run this in the computer software, there are plenty of other programs to do that for PC.)
Last year our class was required to buy Nspires, but this year when I was uploading a Quadratic solver for Nspire I made, I noticed that there was a new OS! I upgraded immediately! Shortly after, I lost my Nspire, so I bought a new one. It was a touchpad, but my teacher didn't know how to use, so he required me to get a regular clickpad, so I bought a clickpad. But then she said I must stick to the same OS everyone else was using, OS 1.3 because she didn't know the menus very well, so I tried to downgrade, I couldn't find the OS anywhere? Could you attach me a copy?-yunhua
I understand that new features will require a new OS, but that still does not explain why I cannot downgrade to a lower OS if I choose. Please help me downgrade my OS, unless there is a valid reason I should not.Thank you.
James,Thank you for the reply.You bring up a good question, one that I do not have an answer to. Since there is nothing documented it may be considered proprietary information but I will forward your question to our developers and see if I can find any information for you. If you do not hear from me within three business days it may indicate that our developers have not responded back to me, please feel free to contact me at that point for any updates that I may have for you.I hope that you find this information helpful. If you have further questions or comments, please feel free to send me an email.Warmest Regards,Cesar Lopez
You have just made my day, Thank you. I really appreciate it. I love learning as much as i can, and this may turn out to be a great opportunity. I am eager for a responce.thank you so much, -James
