    Hello everyone.

    As updating my Lumia 800 to version 7.8 included the preposterous thing of lowering the volume of my phone by a tremendous amount, I'd like to downgrade it back.
    I tried using Zune for that, but it gives me an error so I'm not able to do it.
    I've been Googling for some answers and I found something about a programme called NaviFirmPlus but there seems to be an issue with it.
    Is there any way which I could use to downgrade my phone back to 7.5?
