As far as I can tell that phone was originally released with 4.2.2. This means that there will not be a build of an earler version for that phone, and hence no way of downgrading it.

(Android, like all mobile operating systems, needs to be built for the specific device, so you can't just find a "generic" android 4.0 or 2.3 and install it on your phone. And nobody will have built a custom ROM based on an older version, even if the drivers would work with the older version).
