Hi all,
I just bought a Dell Inspiron N4050 and everything was working properly until I decide to upgrade my BIOS version, from A06 to A07. This was indicated as recommended upgrade on Dell Support page, but this update broke my Bluetooth driver, as you can see below (my system is on Portuguese):
I already tried many approaches to solve, since remove the BT driver and re-installed or using the generic driver provided by Windows 7. Nothing worked for me. When I try to run the old BIOS upgrade utility (N4050A06.EXE), I receive the following message:
Checking further I found some event logs from Windows saying that my BT is not responding, and that is the reason of Windows but it as disabled on Code 43.
Does anyone know how to force BIOS downgrade?
Regards,
Davi Garcia
