General Calculator Help / Re: Installing CAS on TI-Nspire CX Non-CAS
« on: October 06, 2014, 11:17:33 pm »
I have just purchased a Nspire cx non cas and would like to upgrade it to cas. I have gone through this forum and tried a few things but am running into a problem with the os version that I am running. I have 3.2.4.1237 and have not been successful with any of the techniques. Can someone tell me what I need to do to downgrade to an earlier version so that I can continue to install the cas software.

Thank you in advance for the help.
