No. The downgrade protection has changed.

there are libraries since a long time (every document in the MyLibs folder is a "library", because you can access programs(basic ones(if on may call them programs)) in those documents then from every document.

yeah nope no document changes: the things that changes is you can complete the square (as if i needed that i couldve just made a function for it), 3d graphing so ti 89 users have nothing over the nspire anymore except programming, differential equations, stats and probs and finally you can do a lot more with series. which helps in calc bc.

What nspire model are you using? CAS or basic, clickpad or touchpad?

Anybody analysing the new downgrade protection?

It's not in the TNC/TNO header anymore...


Hard-coded in the OS?

They probably did it this way to avoid the following scenario:
  • person installs OS 3.0 on his ancient clickpad TI-Nspire made in 2007 (which still has boot2 1.1.8981)
  • during installation, downgrade protection from TNC/TNO header written to bootdata
  • OS 3.0 won't boot because of the bug in old boot2 versions that prevent them from launching large OSes
  • person reads about bug, deletes OS 3.0 with maintenance menu, tries to install OS 1.7, but...
  • OS 1.7 won't install because of downgrade protection
  • TI forced to fix calc at their own expense to avoid lawsuit

Intresting, they now post a procedure on their website for upgrading from an OS lower than 1.4:

I've just removed the boot2 from the 3.0 TNO file.
I'm currently installing that file on a basic TI-Nspire running boot2 1.4.


I'll tell you if I get anything interesting.

I think it does deserve a double-posting.


I just managed to upgrade and downgrade!!!

I've used:
- a TI-Nspire running boot2 1.4 (won't work with boot2 1.1)
- a modified 3.0 TNO file, with the new 3.0 boot2 removed



I upgraded to the 3.0 OS, which did boot correctly.
I then immediatly downgraded to the 2.1 OS which did boot correctly too.

Seems the new protection is related to the new boot2.
Just use TNOC to remove it before installing the OS.

Thanks for testing this! I was kind of afraid to, since I only have one Nspire.
