If you put them in wrong, the console turns on then very quicky off (had this happen on a zephyr.) Also FTR, if you install the switch or the LT switch, be sure to flip the switch back to the "normal" position mode to read the firmware. Also, for some reeason, while reading and flashing my drive, I had to work quickly. I would get the key and firmware, but when I was ready to flash the LT firmware, it returned error 0x80. I worked faster and did the whole process from reading FW to flashing the CFW in 1 minute. Polrobably my crap computer, but if you have the problem like me, try doing it faster
