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?

Best regards,
