Not sure if this makes sense, but it's an idea anyway: could it be that wrong version of libqmi gets used somehow? You mentioned just changing to latest libqmi, maybe the old version is still around somehow and causes problems? Maybe check using ldd which libqmi is really used, and/or rebuild from scratch after double- checking that any old libqmi version is removed so that it can't pick the wrong one?
