EM7565 problem after firmware update failure

IoT Modules MC/EM Series
1

Hello,

It looks like I bricked this EM7565 card after a failed attempt to update the firmware, now only one USB interface is present and it’s not an AT interface:

dmesg:

ls /dev | grep USB
ttyUSB0

Has anyone encountered this problem?, how do we recover from this?
Thank you

This is the bootloader. You should be able to fix the issue by rerunning the firmware upgrade. Possibly with another firmware version, depending on why it failed initially. But I would have tried the same version first.

Thank you dl5162, the firmware downloading software is finding the device in an unexpected state and stops immediately:

Tried -i -1 & -u -1 options with the same result (also with any other possible option)
I’m using Gobi package S2.36N2.56, It could be failing because of /dev/qcqmi0 not being mapped.
Any other ideas of potentially another package that could work only on /dev/ttyUSBx?
Thank you

Hello there!
Do you have a solution of this problem? I have EM7565 that stuck at QALoder port too :C

you need to use MBPL version upper than R27 to run the lite-fw-download to upgrade module in boot and hold mode

sudo ./bin/fwdwl-litehostx86_64 -c QMI -m 4 -d /dev/ttyUSB0 -f /home/jordan/Downloads/FW_EM74x1/SWI9X50C_01.14.03.00_GENERIC_002.036_010/

I’m using that command:

ubuntu-mate@ubuntu-mate:~$ ./fwdwl-litehostx86_64 -d /dev/$devpath --modelfamily 4 --logfile "fwdwl-lite-$devpath.log" -e 1 --fwpath "./swi_fw0105/"
litefw version :lite-fwSLQS04.00.15 
INFO: QDL Port  : /dev/

From this post:

I’m not Linux user (Windows 99,9% time), how i need to edit this command?
My modem starts with QDLoader port vid 1199:9090 VID/PID

How to check what is my version is and how to install the new one?

you are using the old Gobi SDK.
To download new MBPL SDK, you can go to here:
