General Calculator Help / Reflash boot2 Via Arduino Uno?
« on: July 29, 2012, 02:51:32 am »
Is this possible, I have been trying for a while but I continue to get the error: retrying. I am guessing that the calculator will not accept the boot2 from my computer when trying to send via Xmodem. I am using hyperterminal and it just gives me an error when I try to send the file, it never gets past 0 percent. I am not sure why it refuses to do this. I get to the poing where it says ready to Download boot2 then it will not accept the file it just retries until it reboots. Can anyone give advice?

General Calculator Help / [Q]Boot2 Flashing
« on: March 19, 2012, 12:46:24 am »
Just a question (Don't know if this is a dumb question), What If I were to flash a CAS boot2 to my non-CAS? Would that allow me to install a CAS OS? Or will the boot1 say it isn't valid and break my system. Also Was wondering if someone could clear up the issue we are having with cracking the RSA key. What is the RSA key used for?

Just introducing myself :D. My name is Kevin, and I am joining this forum to learn more about Calculators, and how they function, and hopefully put forward some of my own work.

General Calculator Help / How would I go about to downgrade Ti Nspire 3.1
« on: February 27, 2012, 11:47:57 pm »
I am an idiot and upgraded to this firmware but now I want to downgrade it to something like 2.1. Either way, I came across this and was wondering what else do I need? I have a usb to serial adapter and was wondering If I needed other hardware to change my boot2 so I can downgrade. I found this tutorial as well Can anyone clarify what I need inorder to downgrade (I am not sure what kind of serial this usb to serial adapter is) here are some pics of the serial adapter:


If anyone can please help me I would greatly appreciate it
