I have installed OS3 and now I want to install OS2. My french so bad. But I understand that I should:
1. Install OS3 without boot2
2. Install old version of boot2 via UART.
3. Install OS I want via USB(TI Computer Link)
(Am I right?)
I have done 1 and 2, but I cant install OS2 because "You cant install OS older then installed now". At this moment I have TI Nspire CAS with:
1. boot1 version: 1.4.8916.
2. boot2 version: 1.4.1571
3. OS version: 3.0.2.1791

What do I should do to install OS 2.x?
PS Sorry for my english.
