The Launchpad/FET programmers are JTAG programmers (though not general
purpose ones -- they're designed to be used with MSP430s only), and you
can perform a mass erase using them. The problem you have can't be
solved this way though, because of the JTAG fuse issue.

The bootstrap loader is an entirely different way of accessing the chip
which reads commands and data via a UART interface. Once you've done a
mass erase via the bootstrap loader, you should be able to access it
again via JTAG (i.e. using the Launchpad/FET).
