I have a problem installing fastboot drivers for my X following the instructions in the official flashing instructions: it gives the following link:


But these seem to be regular usb drivers for X, not fastboot. The inf file from the above link lists PID 51E0, which is what device manager shows for my X when I connect it when running Android.

When starting in fastboot mode, device manager shows the X as having PID 0DDE, and of course it won't install the above drivers.

I found https://developer.sonymobile.com/downloads/drivers/fastboot-driver/. That one has inf file with the right PID (0DDE). Trying to install this one with device manager goes one step forward but gives a different error:

"Windows encounter a problem installing the driver software for your device. Windows found driver software for your device but encountered an error while attempting to install it. Android ADB Interface The system cannot find the file specified."

So the inf-file is now the correct one, but something else is missing. What next? Any help is appreciated.

You can do without the Android SDK. Check this page for the drivers on Windows: http://www.droidviews.com/setup-androxyde-flashtool-sony-xperia-devices-windows/

a. If you are running Windows: You need to install additional drivers.

  1. When completing the installation, open the Android SDK Manager and go to the Extras folder to install the Google USB driver.
  2. Download and install an updated Fastboot driver. This is the standardandroid_winusb.inf-file, with a few lines of code added to enable Fastboot to support Sony devices.
  3. Replace the original android_winusb.inf-file with the downloaded file in theusb_driver folder, located in the Android >sdk > extras > google folder on your computer.

Thanks, tested this, and it works. I had Android SDK already installed.
