Downgrade nSpires boot2 via serial?
« on: April 28, 2011, 05:29:24 pm »
I updated to os 3 without removing the new boot2(3D-Graping enticed me) and i want to have the ability to downgrade. I have the hardware to connect the calc to my computer. Well my netduino but it has enough memory to store the boot2 image to send.

I found this post on ti-bank but ti does not say anything on how to send the boot2.

Anyone have anymore info?

I think you use xmodem to send the image to /phoenix/install, but as I've never done it I'm not sure.

Yes, you reset your Nspire while pressing Home+Enter+B, and then send the boot2.img file in Xmodem, as described here:
