Pretty curious.

Beyond what appears to be an aesthetic change, does your APP menu look different, now? (i.e. Datastream access)

[KlaasKuperus]

From your picture (https://cldup.com/YlSFF-HogZ.png) it really looks like the hardware (or at least compatibility) have changed, although that seems weird.. Did you test with an actual network or datastreamer?

It is all part of the riddle hahaha

Haha, got some nice testing to do tomorrow at the office. Would be nice for the stack of Rev-A models I have on my desk to change them.

Eried,

Just curious, how did you manage to apply Arm assembler to the Prime?
(I just checked that this thread didn't originate 1st April ;-)

Erwin.

Riddle Solved!

This is documented in ticalcs and other sites but you basically mount the firmware image file as a drive and then use IDA or something similar.

Well done! So you are ready for riddle 2? Shall we say your riddle "exam"?

Let's do it

[Tim Wessman]

Just please stay away from exam mode stuff... nobody wants an arms race. It will waste our time which means less and less productive stuff will happen. Nobody wants to go the TI route and start encrypting and trying to lock everything down.

We know that from the beginning. We will remain out of the game. Nothing to worry about. With "exam" eried means that will be "final test", It doesn't have anything to do with the exam calculator mode.

[Tim Wessman]

I know. Just restating it for a reminder. :-)

critor showed a modified official firmware running on the Prime several months after the Prime became available on the market, around November 2013 IIRC.

And thoroughly failing at it, predictably
TI's (and HP's) best protection is that pretty much nobody cares, rather than the fact that the code is rock-solid.

It may be less of a, "pretty much nobody cares," than lack of a better mousetrap / security issue. This product is purpose-designed for educators; thus misses the whole other market, (non-educators), who want, and would probably purchase again, a full-blown, unconstrained version, built on this platform.

If there were a bridge between these two target markets to cross over that divide, I think interest would peak dramatically. Those of us less able to create that kind of firmware, and don't see anything emerging that is particularly close at this point, are left with a "nobody cares," sentiment. There's plenty of room for innovation, especially as the OEM firmware matures, to make very desirable enhancements. I would rather obtain firmware from official channels though, rather than a 'hacked' source. Official releases come from a more 'trusted' source, and there are some especially clever hackers out there, that continue to compromise IT devices, (ransomware, etc.). At least, this is what specifically drives my interest in alternate source firmware...

How do I change the firmware?

Short answer: Use the Connectivity Kit.

Complete answer:
Step 1: Install the HP Prime Connectivity Kit on a computer which has a USB port.
Step 2: Run it.
Step 3: Click Help / Check for update. Let it load an update if one is available.
Step 4: Plug your Prime into your computer using a USB cable.
Step 5: When your Prime's name appears on the Connectivity Kit's window, it might ask if you want to update. Say yes. If it doesn't ask, right click your Prime's name and select "Update firmware".
Step 6: Follow the instructions and be patient. It takes a minute or two.

The latest TI Nspire II OS (5.1) seems much harder to crack so far. At least the people at Ndless (who are some of the best TI hackers) haven't been able to do it yet.

Hasn't this somehow happened with the G2 which seems to use a certificate to validate the uploaded firmware?
