When you call 18004myxbox it comes up with an automated thing. Max is its name i believe. He goes through something like unplugging the xbox, taking off the HD, plugging the xbox back in, and turning it on. Then it says to put the HD back on? And i call BS on them saying that it shows signs of being tampered with. They tell you to take off the faceplate when you send it in. I would know because i just got mine back like 3-4 days ago, and its still messed up. Why does xbox makes custom faceplates if they are going to consider it tampereing? Thats not tampering... And yes, I'm pretty sure you screwed yourself in whatever you did because they track the xboxs with the serial number. So when you told them what it was when you sent it in they marked it as tampered. The 3 red lights is either a serious internal problem, or your power supply has failed.
