<div dir="ltr"><div class="gmail_signature"><div dir="ltr"><div>Hi,</div><div><br></div><div>I seem to have one MC7455 in QDL mode. I can see that after bootup it will do several USB interface connect/disconnects, and after that set itself in QDL (this would be normal, according to the specs).</div><div><br></div><div>The reason might be a failed FW upgrade done before installation or any corruption on the board itself so it can not load the firmware. </div><div><br></div><div>I was thinking if there is any way I could solve it without disconnecting the modem and do the normal FW upgrade in another machine. Since the /dev/ttyUSB0 port is exposed, I could, maybe, initiate the FW upgrade via qmi-firmware update.</div><div><br></div><div>Which I tried, but I get following (whole printout at the bottom of the email).</div><div><br></div><div><div>[22 Nov 2017, 05:04:07] [Debug] [qfu,dload-message] sent sdp:</div><div>[22 Nov 2017, 05:04:07] [Debug] [qfu-qdl-device] >> 70:00:00 [3,
