But today , I try to install os3.6 ,it can success install the os, but when it first reboot, it stop at the grey screen with a clock ,and the clock did not work.A few seconds later , it rebooted again,and showed that there is no operating system,please install.
I have tried many times, but it still like this.
At last ,I tried to install os3.1 ,but because the boot2,it refused to install os3.1.
Now ,how can I save my clickpad?

Hi.

Indeed, OSes 3.6/3.9 don't work on ClickPad EVT/DVT prototypes, they just uninstall themselves because of a difference they're checking in the ASIC flags.

To use OSes 3.6/3.9 on ClickPad EVT/DVT prototypes, you need a third party boot loader, like nLaunch CXM : archives_voir.php?id=19507
But nLaunch* require Boot2 1.4. What's your current Boot2 version ? It can be checked with the TI-Nspire Computer Link software for example.

The boot 2 is os 3.6 now

I can not install os3.1 .
WoW
I think I need to flash the boot 2?
Is it right?

There is no 3.6 Boot2.

If you want to run OS 3.6/3.9 on your prototype, yes you'll have to flash Boot2 1.4 and install nLaunch CXM.
