    **Back up all important data to a computer or memory card before starting. It will be lost in the downgrade.

    Download Nokia Software Recovery tool and install. Run it, it will ask you to plug your phone in. When it sees your phone there should be a button labelled install (or words to that effect). Press that and don't unplug the phone or anything until it's finished.

    There is a more detailed guide somewhere on here but that's the short version.

    After you hit go, the phone will restart and the screen will go red, with "NOKIA" in white near the top of the screen and a progress bar. Just let it do it's thing and eventually the bar will fill and the background will go from red to green, then the phone will restart again and you *should* be on the initial set up screen - as if you've switched it on for the first time after taking it out of the box.

    Make sure your cable is plugged in firmly at both ends. Also, if your system has USB3 (the USB socket will be very blue), plug it into one that isn't blue. Apparently USB3 causes issues with the application.
