If you really want to use Boot2 1.4, you have to flash it (option 2).

When I select option 2 (flash), the screen freezes.

Are there other things that I need to prepare, for it to complete successfully?

Flashing takes some seconds.
You should then be able to press 0.

Unless... does it show you a warning/error message?


If it's really a freeze, please provide me with some details as I never ran into this:
- your TI-Npire model
- your original Boot2 version

I pressed 0 and it went back to the previous screen.

1- Does flashing not show any progress indicators, that it has commenced and completed the flashing?
2- How do I know if I have successfully flashed my boot2?
3- How do I check my version of boot2?

There is no progress bar currently.

Your Boot2 version is shown on the main screen.
So you can immediately check if it's been flashed correctly or not.

It looks like I bricked my device. The screen is stuck with the message:

Operating System not found. Install OS now.

Using a linking software, I can see that the My Documents folder doesn't
contain anything.

What should I do from here?

You should, precisely, install an OS, as your boot2 suggests you to ;)

AFAWCT, only the oldest Nspires (prototype or old production Clickpads) can be bricked - and that requires reprogramming the boot1 with garbage, which you haven't done, otherwise you wouldn't see the boot2 telling you to install an OS :)

You can now add me to the list of people who can verify that your work, along with the works of others, function as expected.

I own a TI-Nspire with Touchpad (non CAS).

Inserted below is a picture I just took now of the About screen, after using nsNandMgr, nLaunch, TNOC, and ndless, to "upgrade" my device to the CAS version.



Thank you to all that have made this possible. Your work is well appreciated.

It seems you just have to resend an OS.
But this shouldn't have happened if you 'just' flashed the 1.4 Boot2 - I'm going to check on non-CAS ClickPad/TouchPad again.

when I try to flash my boot2 it gives me this error message:
Image rejected as determined unsafe if flashed on this model
press a key...

What am I doing wrong?

I have Nspire-CX and I'm trying to flash 1.4.1571 boot2

See my TI-Planet PM reply to the topic you created, then deleted, on TI-Planet.

For the reference of others trying to do the same thing which cannot work:

Hi,

I wrote a reply to your message before you suppressed it. Here's my reply anyway ;)

Quote
I have Nspire-CX and my current boot2 is 3.10.16 and I'm trying to flash 1.4.1571 boot2
1.4.1571 boot2 works only for Clickpad and Touchpad calculators. nsNandMgr and FlashBoot2 are fully right not to let you flash that to a CX calculator. If they did, you'd have to fix your calculator through the RS232 port, which requires extra equipment (cheap enough, but not provided out of the box by TI).

Quote
I don't care how I get my boot2 to 1.4.1571
Nobody shall help you making a "dangerous" operation (which will semi-brick your calculator until you reflash the boot2 through the RS232).

Quote
I just need it to happen.
Why, in the first place, do you need to make happen something that will flat out not work and leave your calculator in a sorry state ?
If you're interested in running arbitrary OS (Linux without going through TI's OS, to begin with) on your Nspire CX, then use "nLaunch CX", which works directly with the CX boot2 3.10.16 that you already have ;)
