Hey, i have a SE K800I

and i'd like to put some Generic FrimWare on it, preferably USA, or AMERICIAN
but i dont know which one to put on, so which one would be the best? ( Must have BE ENGLISH)

P.S. When i run the phone with XS++ it asks me if i want to update to cid 52 and says it cant be undone, so should i do that?
