LXNAV S100 calibration and firmware question

I have an S100. I want to calibrate it and have removed it from the glider.. We’ve put it in the calibration chamber, but are not having any luck getting it to record a flight without the gps recognizing movement. Ideas?

Second. I’ve updated firmware before without issues. This time, the file is on the MicroSD, inserted into the slot, the S100 recognizes the update file and asks for “Update?�. I select with lower knob, and press/click to update. The screen goes dark and then stays off. When I restart the instrument, it asks if I want to update. Ideas?

Thanks.
