hello!

i've been searching for this here at the forums but haven't found any clear answer. i'm still new here so i hope this is the right forum to ask this:

if a gamertag/profile is shared across different platforms, namely the 360, xbox one, gfwl and/or windows phone, would it prevent me from modding the gamerscore for my 360 games primarily? i am not familiar if there are any profile mod tools for gfwl, windows phone, or xbox one games, but if there are, same question above: will it prevent me from modding my gamerscore?

thank you.
