FW: adjust KitKat easter egg to display static "K"

*the easter egg is set up to display the first letter of the
 build_id, which is suppose to be a K. However, some devices
 override the build_id with a previous one to match the fingerprint
 which results in some other letter being shown instead. This
 just makes it so it will always display a 'K' like it should.
