Solution 36494: Differences Between TI-Nspire™ Family Handheld Operating Systems 126.96.36.1995 and 188.8.131.521
Why is the handheld operating system for my TI-Nspire Family Unit different than the operating system that is available from Texas Instruments?
For the 3.9 release of the TI-Nspire Family, there are two different operating systems that can be loaded onto TI-Nspire Family Handhelds. The most widely available operating system is posted on education.ti.com, and it is listed as operating system version 184.108.40.2065. However, when upgrading handheld operating systems through the TI-Nspire Navigator™ System, you'll notice that your operating system version is 220.127.116.111.
It is suggested that you upgrade from version 18.104.22.1685 to version 22.214.171.1241 there are some stability and improvements made in this new version.
