qmicli-firmware-update failure on a batch of EM7455

[Amol Lad]

Hi Aleksander,

I'm facing a strange issue. I've received a new batch of Sierra EM7455 modems 
and trying to update firmware in the modem and I get following error message:

# qmi-firmware-update -t /dev/ttyUSB0 -U SWI9X30C_02.33.03.00.cwe 
SWI9X30C_02.33.03.00_VERIZON_002.079_001.nvu
finalizing download... (may take more than one minute, be patient)
error: error downloading image: couldn't write in session: operation returned 
an error status: 134

Any idea what error status 134 could mean? This is definitely something to do 
with the modem and I am able to update EM7455 from an older lot just fine..

How to enable more debugs in qmicli-firmware-update to understand what error 
modem is reporting?

Thanks,
Amol

Problem solved. Just submitted a MR [1] for the unlock script.

Thanks,
