I am on my way porting kitkat to our beloved Razr I. There is not much progress so far, as I started from a mostly fresh product environment a lot of work has to be done with much time consuming testing (The build system is really slow and not everything can be tested without rebuilding the rom).
A bit of a showstopper seems to be the precompiled binaries we need. They are compiled against some JellyBean Android system libraries and are not compatible. Instead of adding to the Kitkat-Libs I really would like to use vendor blobs compiled against Kitkat... Does anybody know of a firmware image of any X86-atom 4.4 Phone?
Development thread and github sources will be published within the next few days - but I still need 9 more posts to get access to that board
