Ok im trying to mod my gamertag with a usb flash drive. i extract the file with Usb Xtaf Xplorer and when i try to extract it the file name says. i pressed save and it said its an invalid file name. So i changed the name to E0000....... and save it. now i opened up Ezgt 2.1(and i have tried 2.2) when i open my profile it says "Wasn't a profile" and "Filename should begin with E0000...". So now i dont know what im doing wrong? any help?
