Default [q] i8190xxamj3

Hello:

I installed I8190AMJ3.ZIP from here:
http://forum.xda-developers.com/show....php?t=2546043)

I had two problems:

1) Doesn't appear any csc with csc select; I needed PHE; them I copy csc folder from another rom, and it Works

2) When I want choose melody for phonebook contacts, I ca'nt do it from "My files" because this application is not installed.

How can I install "My files", and it Works as explorer in other applications as phonebook when choose melody?

THANKS

REGARDS
