Gamerscore was modded by friend

my friend modded my gamerscore would u please derank it

And? What's your point? Nobody is harassing you. If you don't want negative responses then play by the rules and don't mod your gamerscore. And especially don't mod your gamerscore and then lie saying it was your friend.

Hello Obey,

These forums are for official support. Any discussion of modding, or troubleshooting involving modded accounts/consoles, is not allowed as per the Xbox
Forum Guidelines.

We will be locking this thread. if you have another question, don't hesitate to create a new thread. We look forward to hearing more from you soon!

There isn't anything you can do. Microsoft's stance on this is whatever happens on your account is your responsibility even if someone else was using it. You will probably end up with a gamerscore reset and your profile marked as a cheat.

you should contact support and see if they can help
