I really believe this is a firmware bug of some sort, nothing to do with libqmi.

Could it be that whenever an image is uploaded, the
"index_of_running_image" gets the value from the "storage index", but
then after doing selections with --dms-select-stored-image the
"index_of_running_image" is again the correct one, i.e. the index from
the list reported?
