Can I buy old Xbox 360 gamer pics so I can change it when I play xbox360 games on my Xbox one

I'm Samy an independent advisor. Welcome to the Xbox community. How are you?

You can add a custom gamerpic to your account via the Xbox app on your phone or the Xbox Companion app on your PC. And there are no costs for that.

How do you change your Xbox One gamer pic back to your Xbox 360 gamer pic? I changed mine for my clan and now I want my old Xbox 360 gamer pic back on showing my Xbox One. How do I do that?

Oh and a reason why I no longer have my Xbox 360 gamer picture, is I messed around with avatar app on Xbox One exited without saving and now it's changed my gamer pic to what you see now. I can still change it though. However when I log in on my Xbox 360
slim console, my original Xbox 360 gamer pic is still there.

Iv tried everything that I no now, turned everything off, reset the wifi, turned the smartglass on, in the settings on the xbox, the screen come up on the laptop, and I can see what games have been played but once I try to connect the smartglass it says
console not listed, and keeps bringing up the xbox 360 ip address, also when I log on to the xbox one site it has my old gamer pic from xbox360.

I created a gamer pic on my xbox one and the only one that shows on the forums is my old one from my 360 and when I go to change it in the edit profile it says I have to log into my 360. Why can't I make that change on my xbox one since it is my console
now and not the 360?
