The MC400 already has two SIM Card slots. Plus, his question was related to flashing the modem.

Has anyone been able to get the second sim slot on a MC400LP6 to work? I am using the MC400LP6 as a stand alone USB attached modem and it works well except for getting the second slot to work. I have tried both the ATT image after a factory reset and a separate current ATT image. I enable and pick the slot as in this thread and boot the modem with a sim in the second slot and with the slot selected. The status is always "sim not inserted".
I am beginning to think that there is some additional AT command to enable the second slot.
