Bluetooth firmware downgrade on linux
I have a D820 that was purchased pre installed with Vista I have since installed linux. (non duel boot)
I have been unable to get bluetooth to work but have found that Vista updates the firmware to allow bluetooth kbd and mice to work in bios
Below appears to be the fix but requires Windows which I no longer have
1) Boot into Vista and download from the Dell support site the last BT 350 driver for Windows XP and unzip it in a folder
2) Find a directory in that folder called "DFU"
3) Find the file called "DFU.exe", right click it and choose "Run as administrator"
4) Wait until the firmware downgrade has finished, then reboot into Vista and you will find that the bluetooth chip is now not recognized. Go to Device manager and manually reinstall the Vista BT driver (don't use the setup.exe provided by the driver pack, simply install it using the "have disk" way and load the .inf file directly from the Vista driver directory).
5) Reboot into Linux. Voilà but I can not find a way to get the firmware install done on a linux only box. can anyone point me in the correct direction.
is there a linux version of DFU.exe?
