That sounds accurate. If the machine is locked and you want to avoid
the hassle of getting a dev key, take the file
/bootpart/boot/bootfw.zip from a XO-1.5 12.1.0 machine and put it in
the same place on the XO in question, overwriting the previous file.
Then reboot the system with power attached (normal boot - don't try to
reflash yet), it should auto-update the firmware.
