We are able to send OSes between calculators, which means the RSA signature is kept somewhere in ROM.

On basic TI-84+, the signature found at the end of the .8Xu file seems to be at 0xE8100 in ROM files.
But strangely, I wasn't able to find such offsets for other models (TI-83+, TI-83+SE, TI-84+SE).


Can you tell me more on that?


Thanks.
Unless I'm misremembering, don't most of the calculators use a Rabin cryptosystem and not RSA?
