EM7430 QMI devices error

[pagu586]

sudo qmicli --device-open-mbim -p -d /dev/cdc-wdm0 --dms-swi-set-usb-composition=6
[/dev/cdc-wdm0] Successfully set USB composition

     You may want to power-cycle the modem now, or just set it offline and reset it:
             $> sudo qmicli ... --dms-set-operating-mode=offline
             $> sudo qmicli ... --dms-set-operating-mode=reset

sudo qmicli --device-open-mbim -p -d /dev/cdc-wdm0 --dms-set-operating-mode=reset
[/dev/cdc-wdm0] Operating mode set successfully

couldn’t QMI devices /dev/cdc-wdm0

After executing the above command, the QMI device was no longer recognized and I was unable to do anything.

Is there any way to cure it?

echo 1199 9077 > /sys/bus/usb-serial/drivers/option1/new_id

I was able to get it recognized using modprobe, but QMI and QDL don’t recognize it, so I can’t update the firmware.

you need to use the MBPL USB driver: ( MBPL_DRIVERS_R35_ENG4-usb-src.tar)

https://source.sierrawireless.com/resources/airprime/software/mbpl/mbpl-software-latest/#sthash.ZXRwiiKx.Ih35ge9z.dpbs

BTW, what is the response on these AT commands?

ati3
at!entercnd="A710"
at!usbcomp=?
at!usbcomp?

Lastly, you should use USB PID 9071 instead of 9077:

Em7430 no com port after vid:pid change

oh god, i did fix this by many many wierd steps on both Windows10 and Ubuntu 20.04, thanks you @dl5162 , this .nvu is helpful to change the pid, so driver and usb bus can be detected, my works are: using physical pc, dont use virtual machine with usb passthrough because the vm host will not detect usb bus without driver Clean the hardware, m2 pin, m2 adapter pin to avoid pin missing or short must know the device usb setting, i remember it was 3 so i plug it on usb 3.0 port Plug in on windows 1…

at!usbpid?
!USBPID:
APP : 9071
BOOT: 9070

OK
