Dell Latitude 5400 Firmware update trouble

Latitude 5400 – “Configuring mobile broadband device” – no WWAN hardware is present

Fix for the “errror” when Dell Latituce 5400 loops with firmware updating.

Create VBS file

Const ForReading = 1
Const ForWriting = 2

Set fso = CreateObject(“Scripting.FileSystemObject”)
FileToChange = “C:\windows\firmware\FwSwitchbin\fbconfig.ini” If fso.FileExists(FileToChange) Then set oFile = fso.OpenTextFile(FileToChange, ForReading)
sText = oFile.ReadAll

sNewText = Replace(sText, “;FLASH_SIM_NEED = 1”, “FLASH_SIM_NEED = 1”)

set oFile = fso.OpenTextFile(fileToChange, ForWriting)
oFile.WriteLine sNewText
End If

This will find the file and change it so that the firmware will be silenced for ever.
