There is an guide available for creating an ftf file yourself. It can be found here
You can also look for the World A (C2104) or Generic World (C2105) which is the international version.
A list of ftf files can be found here
And last, you can also use my C2105 UK ftf file in my signature, but its 15.3.A.0.26
and not 15.3.A.1.14
