You need to type “legato start” in console ---

can you re-download the FW with one click EXE in windows? seems something is missing in your module ---

I’m running on a virtual machine because i have read that windows is not supported. This is maybe the problem? ---

you might also swiflash in linux to flash the image [https://source.sierrawireless.com/resources/airprime/software/swiflash/#sthash.A1vix7Wb.dpbs](https://source.sierrawireless.com/resources/airprime/software/swiflash/#sthash.A1vix7Wb.dpbs) ---

is it ok to flash FW? You can upgrade FW in Windows with EXE file ---

Yeah, i will try. Do i need to start all over again? ---

what do you mean by start all over again? Just download the FW in windows and see if “legato status” is running ---

Seems it cannot find the usb DM port in linux. You might also try one click exe in windows ---

what did you see in the one click tool? Another unofficial way to update module FW is as follows: 1. download a WP77 FW EXE 2. use 7zip to extract it 3. there should be a fdt2.exe inside 4. put the new xxx.cwe inside the same folder 5. use command prompt to update by “fdt2.exe xxx.cwe” > **[AT Commands problem FX30S](https://forum.sierrawireless.com/t/at-commands-problem-fx30s/22764/14)** > > I don’t know the password of your device… Another unofficial way to update module FW is as follows: download a WP77 FW EXE use 7zip to extract it there should be a fdt2.exe inside put the new xxx.cwe inside the same folder use command prompt to... ---
