    Hi, I think my cell originally may have had a TTT rom, but the thing is I bought the cell in Chile, and it’s indeed a southamerican model, SM-G900M, but I am wondering if I can just install any southamerican ROM in it, be it Chile (CHO) or any other country’s rom?

    Will the cell phone remain rooted after this, or will I need to root it again?
