Hi,<br>
<div class="moz-forward-container"> <br>
I try to updated the firmware of modem Sierra Wireless EM7455.<br>
Without success.<br>
<br>
I download the latest version of libqmi from its Git repository.<br>
I satisfy compilation prerequisites.<br>
I compile and install libqmi without errors.<br>
When the firmware starts, I see error:<br>
<span
