Not so long ago, we reported about the Boot2 that comes with OS 3.0.1 installing a strong anti-downgrade protection on your TI-Nspire that couldn't be bypassed without extra hardware. Well... this was nothing. Now you got even more reasons to run your OS through TNOC before installing it on your calculator, because now there are at least 4 reports of calculators being bricked by unmodified OS 3.0.1 copies!
