I accidentally flashed a new firmware onto the Modem and now i can’t get it out of low power mode or flash to another firmware.

```auto
AT!IMPREF?
!IMPREF: 
 preferred fw version: 02.24.05.06
 preferred carrier name: GENERIC
 preferred config name: GENERIC_002.026_000

 current fw version: 02.33.03.00
 current carrier name: GENERIC
 current config name: GENERIC_002.026_000
 current subpri index: 000

 fw version mismatch

OK

```

This is the version mismatch i have, but everytime i try to flash another firmware onto it, i get

```auto
FDT version: 1.0.1806.0

i need a link for the old firmware (since i only have newer one) and a way to flash it to the modem, but i simply don’t know how to do anymore.

if you can help me i will be very grateful, thank you.

Does this help to find old firmware?

Thank you for the Firmware link!

Yes, i installed both Qualcomm-HS-USB-QDLoader-9008-Driver and Qualcomm USB Driver v1.0.10061.1.

I still get

when trying to run FDT.

While using QFIL, it says no port available

which i guess is because the modem doesn’t show up as a COM Port, but as a Network Adapter

My guess is that this whole trouble is over once i flash the old correct firmware, but i dont know how to that with all the errors i am encoutering.

BTW, you can see here on other user update the DELL DW5819 driver: (From your screenshot, you are using DW5818)

i now have 3 COM Ports, but either 2 of them are active, or the other one  
 ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/b/bcb6646039f238a1339d6805ac196255fc210860.png)

my AT Commands only work on COM6.  
This is another thing that is happening. When i connect it, i have a small time windows in which com5&com6 are there and then it disconnects and only com3 is there.

on my linux VW, it behaves likes this:  
i have ttyUSB0, ttyUSB1 and ttyUSB2 at first and i can type my commands with screen/dev/ttyUSB2/.

but then, it kicks me and only ttyUSB0 is there. when i open screen/ttyUSB0/, every character i enter is displayed as ‘0’, with now way to press enter (pressing enter will just add another ‘0’).

AT Commands work for a brieve moment on COM6/ttyUSB2  
after that, only COM3/ttyUSB0 is available with only zeroes

i did enter your AT Commands.

```auto

AT!ENTERCND="A710"

if you use AT!USBCOMP=1,1,100D as previous case, will the module kick you out from AT command mode?
