If you mean in the calc to check if the checksum is right, it is in the
bootloader, and that is unchangeble. (without soldering Iron)
even if it was in ordinary changeble flash, it wouldn't make any difference..
think about it.. ofcourse it checks the rom before it is installed. And then
your changes have not had any effect.
To generate is no problem. To encrypt it afterwards is impossible without TI:s
private key.
