Great discovery.

The boot splash screen and OS icons are different from the production ones and similar to the ones already spotted on the TI-Nspire Color.

Are some of you getting it?
3.0.1.1651 is of course undumped, but the most interesting thing with those prototypes is that their Boot1 is on an external reflashable documented chip:

Yes, but with the downgrade protection it wouldn't say "update succesfully".



Let's reformat the filesystem.

While holding the reset button, press and hold simultaneously the 3 keys Home Enter EE, and then release the reset button.

You should get the maintenance menu around 60% of the loading bar.
Press 4 to clean the whole filesystem.

I think most people who have an HP Prime are on HP Museum forums it seems. It's hard to attract HP fans on a TI forum when there is an established HP-only board around, same problem we had with Casio people. Certain people might see TI boards as the "enemy" or something.

Then they have some maturity problem. TI-Planet is for maths and programming, and I don't see why we should restrict ourselves to one manufacturer when things are similar with other manufacturers models.

Both Cemetech and Omnimaga also deal with non-TI calculators, especially Casio. Omnimaga was affiliated with Planete-Casio long before TI-Planet.


And we're not being nicer with TI or less nice with other calculators manufacturers.

I'll easily admit that the TI-84 Plus CSE is a bad product although it seems to have been adopted by many people (based on the ticalc.org uploads).

I don't approve the latest TI-Nspire CX hardware.

I'll also admit that the Casio Prizm fx-CG10/20 is a very good product (and I'm sad it failed to be adopted and that interest for it did apparently die).

But I'll tell you that the Casio ClassPad II fx-CP400 is currently a bad thing (only the main (calculator) application can be rotated, Basic is far slower than on the TI-81/80 from the last century, except for the home screen the rest of the OS just copies the heavy black & white GUI of older Classpad calculators with many borders and hasn't been adapted at all for the color screen...). Let's hope for an OS update although they tend to be quite rare with Casio...

Classpad 300/330/400 native code programs should indeed be fast in relative terms if compared to TI-Z80, or to a lesser extent, TI-68k native code programs, but usually worse than Nspire (where native code programs are becoming a thing of the past)

Do you mean that we've lost the TI-Nspire battle and won't be able to bring native support back with the new hardware and OS?

Thank you DJ for your reply. I've just a little question about it.

Then try to get an used one somewhere while making sure that it ends with the letter H or below

Was it confirmed that HW-H Nspire CX are compatible with Boot2 3.1 and that HW-I are not?

In fact it's 2225022676 P-0213I.

You've got hardware revision I, and it came preflashed with the 3.2.4 versions if I understood well.

As for today, we don't know if HW-I can be downgraded to 3.1 versions.

Assuming it cas, you need an USB/TLL interface. They're often using an FTDI chip:



You then connect 3 cables to the following pins on the Dock/J01 port:


And you just send the 3.1 Boot2 image file with the HyperTerminal software included on Windows for example.

We just need to export the new B-Calls from OS 2.55/ORk.

Yes, with the Trace key I think.
