TI has released version 3.1.0.392 of their Nspire OS. It is available at http://education.ti.com/calculators/downloads/US/Software/Search/Results?cp=6001 .
According to Ti-Planet you are still should able to downgrade to 3.0.2 .

The CX boot2 has been updated to version 3.1.0.16, while the the other Nspire's stay at 3.0.1.131.

Thanks to Ti-Planet for reporting the news.

It seems that the lua print() function doesn't print to the console (or RS232) anymore....

Hm, this is newsworthy. So we can't control RS232 stuff in Lua?

I dont know yet, I only have tested the OS on the computer software, and now the print() function doesn't work anymore.
I hope it's not the same on the calc itself.

Or to stop easy dumping/debugging.
I really really hope its only for the software, otherwise I'm going to cry

Adriweb, do you still see the messages when the calc is booting up? If so, I think it is just the lua print function that is affected.

you guys can tell me what to type for oclua, and I can test it (Have it in mah calc right now)

Dump of the Lua environment: http://paste.bwns.be/p/m22cc805b .
print is removed (the one in the dump is a function we defined to work more easy) in the software, and according to calc84maniac it doesn't work in the emulator (that means also on calc).
So no more sound and other fun stuff with the serial port in 3.1.0 :'(

Also, there is another function added named gcinfo, we are busy finding its use.
