exProfileEditor 2.0.315.1 Released 18.May.2013 Great new update and fixes. Its the only tool I would use if your wanting to do any profile modding of this sort. Do Not Use Le Fluffie as it corrupts your XBL Profile everytime. adf.ly: exProfileEditor 2.0.315.1 or AdF.ly Quick TUT Extract you entire contents of your profile to a new folder using Horizon and open the folder up in exProfileEditor edit what you want to change and save. Once done there will be a new folder called "Changed Files" inside the new folder just inject those files back into your profile again using Horizon and rehash resign and save and your done. Always backup your profile first and sign into your profile offline on your Xbox360 just to check everything is OK. Hope this helps don't forget to say thanks if it helped you. And leave a comment if you need any help with using this.
