Both great questions, and I don't think there's an answer for Linux.
 Also be wary of random firmware, I've had devices re-locked to a
specific operator after flashing them.

You might be able to try different usb_modeswitch magic since that
flips some devices to different modes, or you might be able to use
AT^U2DIAG to do the switch too.  But be careful with U2DIAG since it
has the possibility to brick the device.
