You need to make sure that the changes you're going to make are compatable with the ROM you're using. Do you know off hand if you're on a 6.1 or 6.5 version? Is it still stock uscc? Do you have any other mods on the phone? In all honesty, your best bet is to take a little bit to read up on what you want to do, not just jump into it saying I want this, this and this. Understand what you're doing and we'll all be here to help. first things first though, make sure all your contacts are backed up, since it you load something that borks your phone, you may need to do a hard reset which will erase all of that data.
