After the erase procedure the calculator had always drawn about 8 mA from the power supply. It now draws only 1.8 mA no matter what. If there's a way to recover, I don't know what it is.

It is a common mistake in boot loader software design, that it is not completely immune against midway interruption. Even in some Application Notes of processor manufacturers you may find these wrong designs. I think the MySamba compatible boot loader is hardcoded in the ARM processor, but possibly they made the same mistakes there.

The new ACTs boot loader is immune against midway transmission interruption.
