Default Downgrading Kitkat 4.4.2 to 4.2

Dear all,

I managed to get my HTC One Dual Sim to 4.4.2 Kitkat (European version) - happy with the software BUT, I am unhappy with the bluetooth, it is not functioning well in my car, sometimes connects, sometimes doesn't connect. How can I downgrade it to the previous version 4.2? Please guide me the steps and download links.

Thank you all

you can't downgrade it officially.

First S-OFF then use 3rd party's ROM..
