before you update to lt, make sure you save your dummy's. other wise you have to do the mra hack to get your firmware off.
he doesn't necessarily have to do mra. he could use the probe method. since he already has the 1.6 firmware on his drive, the cal data is long gone. it will make no difference which method he uses to get the dummy info.
that being said, saving it now would make sense and make things easier in the future
