when I try to flash my boot2 using nsNandMgr 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 my current boot2 is 3.10.16 and I'm trying to flash 1.4.1571 boot2

my current OS is 3.1.0.392

Help please

I also tried FlashBoot2. When I flashed it, the calculator restarted and when I checked my boot it hasn't change. I don't care how I get my boot2 to 1.4.1571, I just need it to happen.

No need to create multiple topics

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).

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).

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

But indeed, don't create multiple topics, it won't get you anything more and they will get deleted anyway

heimsothe -> I don't know what you intend to do, but you should have a look at the latest news / tutorials about nLaunch CX.

On which page did you deduce that you had to install Boot2 1.4 on your TI-Nspire CX?
It might be that some of our tutorials need some clarification/update.

Thanks.
