Starts with MP-signed firmware. Then successively tries to flash three versions
to RW: dev, corrupted first byte, and corrupted last byte. Each of these should
flash successfully, but fail to boot (i.e., stay in RO mode). Finally, it
flashes an MP-signed version, which should successfully boot to RW.
