Thank you for the reply, but I don’t have modem manager installed at all. I do have libqmi, but there is no active process running that would be related to the device.
However, after the first failure something must be wrong now, because now it fails with a callback status code.
./fwdldarm -s ./slqssdk -d 9x30 -p /tmp/
