Anyone have any experience with modding profiles over the cloud on 360?

I’m able to mod my profile off of my thumb drive no problem, but when i try to mod my buddies profile after downloading it to my thumb drive of course, the mod doesn’t stick. But every time i re-open the profile on horizon it says everything is there. Am i missing something here? I can’t figure this out for the life of me and any help is greatly appreciated.

Are you connecting to Xbox LIVE before modifying the profile further? This will sync the data. Be sure to select “Save, Re-hash, and Resign” before closing as well.

PS: I hope for your sake your not modifying your friends profile using Diamond-Subcription only tools!? This is against HorizonMB’s Terms of Service.
