After DiagsLauncher comes Boot2Launcher
« on: March 30, 2011, 05:24:59 pm »
As mentionned in the previous news article, the method used by DiagsLauncher to circumvent the RSA signatures protections to launch any Diagnostic Software images on any TI-Nspire model, this method could be possibly used to do the same with Boot1 and Boot2. Well, here comes Boot2Launcher, by bsl too!



Boot2 is what verifies the OS and launch it, for example to disallow the execution of commercial OSes on prototype models for example. What could possibility be done with a modified Boot2 image?

Thank you for the news.

Just for information, Boot2Launcher has been developped by Bsl.

This is awesome! So it means we can develop and boot 3rd party boot2 and OSes on the Nspire?

This is a great day in the Nspire history.

Now I want an Nspire.

now the hard part, making an entire OS :P

though it would probably take 1/3rd the size of the current OS, and be 6 times better.

Woah, modified boot image! This looks great, how awesome!

The community is moving faster, but still thanks to Ndless :D

also, this is good because if we crack the RSA and TI changes it, then we're not totally screwed :P

As I understand it, no. If you want to run a modified OS, you need this and a modified boot2. But it will give you problems on a reboot. I don't think there is  a way to install a custom OS, as boot2 is checked by boot1 every boot. All this does is launch boot2 directly so boot1 does not check it. Every time you want to run your custom OS you would need to boot a normal OS, ndless it, and then run this. (I have no idea what the next step to get the loaded boot2 to load your os wold be. Just drag a tnc into ti-link?)

Please correct me if I'm wrong, I think this also requires you to re-install the os at every reboot. (As the installed boot2 would reject the custom image)

So for this to be useful for that you would need to modify boot2 to accept all OSes (I don't know how) and then pack your custom OS in an image inside a tno/tnc. But as goplat suggested in the other thread, the best way to load your own os is just as an ndless prog.

And it's more likely to rain pink robotic unicorns then it is for the RSA key to be factored.

:D Nobody can stop us, not even the mighty TI!

I'm sure we can hack the CX in half the time it took us for this. :P

I wonder if they'll postpone the CX to fix this stuff when they find out about this...

I bet it will take longer than it did to hack the Prizm. :P

Maybe built in ndless. No more reinstalling. I switch between the ti-84 pad and the nspire ones.

Well, that was an insanely fast hack :P

Maybe built in ndless. No more reinstalling. I switch between the ti-84 pad and the nspire ones.

Or an entirely new OS. The possibilities are Ndless (:P).

But that's a really good idea, for compatibility. Plus teachers/parents wouldn't get suspicious.
