EM7565 problem after firmware update failure

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
