Hi,<br>
<br>
I try to update the firmware of modem Sierra Wireless MC7355.<br>
I use the command when logged as root:<br>
<font size="+1" face="Courier New, Courier, monospace">#
qmi-firmware-update \<br>
--update \<br>
-d $USB_ID \<br>
$FIRMWARE_IMG \<br>
-L /tmp/qfu.log<br>
</font><br>
An error appears:<br>
loading device information before the update...<br>
error: couldn't open QMI device: Failure<br>
<br>
I attach additional information.<br>
<br>
What is the reason?<br>
What troubleshooting steps should I take.<br>
<br>
Note: I am not a developer and I do not understand source code in
C/C++.<br>
<br>
Thank you in advance,<br>
Pavlin Georgiev<br>
