One of the guesses I've made earlier during the first few minutes of the release (actually, add an hour to that to accompany the actual release time :P) is that TI deleted all OS upgrade code in boot2 (hence the shrunken size). *However*, if OS 3.0 can still be reinstalled, it may indicate:

1) A boot2 with significantly less checks... aka only a version check.
2) A boot2 relegating the checks to some magical code in the OS image... stupid idea for protecting, but hey, it's TI.
3) A boot2 [insert something crazy/insane TI would do here]

Of course, we have no idea what weirdness TI has for us until boot2 is disassembled and analyzed... and perhaps harassed to death with random testcases... :P

Yes, I've done it many times on prototype Nspire calculators, with my RS232 interface.
You can send me all your bricked Nspire. Just include the return shipping cost ;)

But I don't know if downgrading the boot2 will be enough. It might have allready modified something permanently in the NAND ROM...


so critor is there a way to modify the boot2 so nspire 2.x or 1.x documents can work on the new os (3.0)?

Old documents don't work?...

Oh nice. I like how you already found cheats as soon as the OS gets released.

Running Ndless is not related to the boot2 but to the OS.

Here's the TI-Bank news about downgrading, with the link to TNOC at the end.

To my advice, you should download it quickly, before TI asks us to remove it...

I think you should news, or edit the 1st post about the downgrade protection.

The TNOC way can only work if applied before the 3.0 upgrade.
Else, you'll have to buy an RS232 interface, or send the calculator to me.

critor, I've downloaded TNOC and mirrored it. :)
If you don't mind, I'll eventually also be mirroring all the OSes on TI-Bank as well. ;)

(I maintain a "secret" mirror - that is, it's available for public use, but can't be found on Google. A person would have to PM me to get a link to my little mirror.)

Also, is there maybe an "easy" way to build the RS232 interfacing?

I added it!  Thank you for your tests, critor! :)

I guess TI didn't think we could beat our established record of about 2 weeks with Nleash. :P
